imdur 40 mg

In 10 healthy male subjects the pharmacokinetics and haemodynamic effects of sustained-release isosorbide-5-mononitrate 60 mg (IS-5-MN) were studied after oral administration at two different times in the day (08.00 h and 20.00 h). Effects on blood pressure and heart rate after 3 min standing upright were measured in relation to the individual circadian control values. The pharmacokinetic parameters (Cmax, tmax, AUC, t 1/2) did not differ after morning and after evening dosing, tmax being 5.2 h and 4.9 h, respectively. In contrast, the cardiovascular effects of IS-5-MN were clearly circadian phase-dependent. The maximum decrease in blood pressure decrease and increase in heart rate occurred significantly earlier after the evening (BPsys 2.8 h; BPdia 2.9 h; HR 3.8 h) than after the morning dose (BPsys 5.0 h; BPdia 6.0 h; HR 5.2 h). Thus, the peak haemodynamic effects coincided with the peak drug concentration after the morning dose, whereas the peak effect was in advance of the peak drug concentration after the evening dose of IS-5-MN. The data provide evidence of circadian phase-dependency in the dose-response relationship of oral IS-5-MN.

This study was designed to determine the extent, to which isosorbide-5-mononitrate (5-ISMN) contributes to the hemodynamic effect of isosorbide dinitrate (ISDN) in conscious dogs. Test drugs (ISDN or 5-ISMN) were given orally. Either ISDN or 5-ISMN produced a decrease in blood pressure dose-dependently, the decrease in pulse pressure being specific; the pattern of blood pressure change induced by ISDN or 5-ISMN was different from that induced by nifedipine or prazosin. The effect of ISDN (2 mg/kg) was almost equivalent to that of 5-ISMN (4 mg/kg) and the effect of ISDN (4 mg/kg) to that of 5-ISMN (8 mg/kg). After administration of ISDN, both ISDN and 5-ISMN appeared in the plasma, and the effect of ISDN well-correlated with the increase in the plasma concentration of 5-ISMN. Contribution of 5-ISMN to the effect of ISDN was estimated to be about 30% from the value of the plasma concentration of 5-ISMN at 3 to 4 hr after administration, when the maximal response to ISDN occurred. Based on the data of the area under the plasma concentration curve of 5-ISMN (from 0 to 10 hr after administration), the fraction of biotransformation to 5-ISMN from ISDN was calculated to be 73.6 to 76.6% (based on moles). Because the ability of 5-ISMN to decrease pulse pressure was about 1/2 (or 41% based on moles) of that of ISDN, the contribution of 5-ISMN to the effect of ISDN was estimated to be about 30% in total, the value being similar with that estimated at 3 to 4 hr after administration.

One hundred and forty-four MHD patients with hypertension were enrolled in this perspective, randomized, controlled, single-center trial. All patients accepted antihypertensive drugs at baseline, including renin-angiotensin system inhibitor, calcium channel blocker, ß-receptor blocker or a-receptor blocker. Seventy-two patients (nitrate group) took isosorbide mononitrate 30 mg daily, titered to a maximal dosage of 120 mg daily for 24 weeks. The dosage was adjusted once a week according to BP. The remaining 72 patients (non-nitrate group) did not take nitrate drugs other than antihypertensive drugs. BP, left ventricular mass index (LVMI), heart rate, interdialytic weight gain (IDWG) and hemoglobin (Hb) were monitored.

The aim of this work was to optimize time-dependent tablets using artificial neural network (ANN). The time-dependent tablet consisted of a tablet core, which contained sustained release pellets (70% isosorbide-5-mononitrate [5-ISMN]), immediate release granules (30% 5-ISMN), superdisintegrating agent (sodium carboxymethylstarch, CMS-Na), and other excipients, surrounded by a coating layer composed of a water-insoluble ethylcellulose and a water-soluble channeling agent. The chosen independent variables, i.e., X(1) coating level of tablets, X(2) coating level of pellets, and X(3) CMS-Na level, were optimized with a three-factor, three-level Box-Behnken design. Data were analyzed for modeling and optimizing the release profile using ANN. Response surface plots were used to relate the dependent and the independent variables. The optimized values for the factors X(1)-X(3) were 4.1, 14.1, and 29.8%, respectively. Optimized formulations were prepared according to the factor combinations dictated by ANN. In each case, the observed drug release data of the optimized formulations were close to the predicted release pattern. An in vitro model for predicting the effect of food on release behavior of optimized products was used in this study. It was concluded that neural network technique could be particularly suitable in the pharmaceutical technology of time-dependent dosage forms where systems were complex and nonlinear relationships often existed between the independent and the dependent variables.

A case-control study was conducted using the Dutch PHARMO Record Linkage System (1991-2002, n = 6,763 hip fracture cases and 26,341 controls). Cases had their first admission for hip fracture, whereas controls had not sustained any fracture after enrollment. Current users of organic nitrates were patients who had received a prescription within 90 d before the index date. The analyses were adjusted for disease and drug history.

The hypothesis that nitrates evoke prostacyclin production by vascular endothelium has been reevaluated on cultured umbilical vein endothelial cells and in vascular fragments, both obtained from humans. Endothelial cell monolayers (passages 1 and 2) were washed free of culture medium and exposed for 3 to 5 min to buffer or nitroglycerin (NTG), isosorbide dinitrate (ISDN), or isosorbide-5-mononitrate (ISMN) over a range of concentrations (10(-9)M to 10(-6)M) encompassing those usually attained in vivo, with or without 25 microM sodium arachidonate. Basal prostacyclin production, measured by radioimmunoassay of the stable metabolite 6-keto-PGF1 alpha, depended on cell density in the endothelial monolayer (being higher in preconfluent cultures) and on incubation time. Basal prostacyclin, however, was not altered by incubation with NTG (3.3 +/- 2.0 pg/1000 cells without drug vs 3.9 +/- 3.8 pg/1000 cells with drug, mean +/- SD), ISDN (3.1 +/- 1.9 vs 3.1 +/- 2.2), or ISMN (2.0 +/- 0.9 vs 2.3 +/- 1.5) at 10(-7)M (all differences NS). Also, long-term incubation (2, 6, and 24 hr) with ISDN and ISMN did not alter prostacyclin production over control. Over a 30-fold increase (p less than .001) in prostacyclin production was obtained with arachidonate stimulation, but incubation with nitrates did not significantly modify the stimulated production. Saphenous vein, mesenteric artery, and atrial appendage fragments incubated at 37 degrees C for 20 min in a shaking water bath with a control buffer produced 27.8 +/- 13.9, 189.7 +/- 75.2, and 662.3 +/- 390.6 pg 6-keto-PGF1 alpha/mg tissue, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

The FMD decreased significantly (from 5.97±2.88 to 5.33±2.56%) in the ISMN group, whereas it increased from 6.27±3.23 to 6.96±2.84% in the control group after treatment for 1 year. There was a significant difference in the changes in FMD when the two groups were compared (-0.64±1.83 vs. 0.69±1.77%, P=0.006). There were no significant changes in serum superoxide dismutase, malondialdehyde, and hypersensitive C-reactive protein levels in the two groups.

The MTACs of low molecular weight (LMW) solutes in the ISMN period were greater than the placebo period: median urea, 16.7 vs 13.8 ml/min; creatinine (Cr), 7.9 vs 6.9 ml/min; and urate, 6.1 vs 5.5 ml/min (p < 0.05 for all except MTAC of urea). Administration of ISMN could also enhance the clearances of high molecular weight (HMW) solute with a magnitude of increase as follows: 10% for beta2-microglobulin, 50% for albumin, and 15% for immunoglobulin G (p < 0.05 for all). However, the values of restrictive coefficient of LMW as well as HMW solutes of both groups were not different, indicating that the increased solute transports are not due to alteration in the peritoneal membrane permeability. Despite the increased peritoneal solute clearance, net ultrafiltration (UF) was unchanged after drug administration, 110 (ISMN group) vs 120 ml (placebo group), (NS).

Temporary proteinuria occurring after exercise is a common finding, and it is explained predominantly by alterations in renal hemodynamics. In this study, we investigated whether nitric oxide (NO), which is known to have an effect on renal hemodynamics and to increase during exercise, has a role in postexercise proteinuria. In the first step of this study, the effect of acute NO synthase blockage on exercise proteinuria was evaluated. The urinary protein levels in animals that performed acute exhaustive treadmill running exercise were considerably elevated compared with the control animals. Significantly elevated urinary protein levels were also detected in animals that received Nomega-nitro-L-arginine methyl ester before exhaustion, compared with both control and exhausted groups, and mixed-type proteinuria was detected in electrophoresis, as in all exhausted animals. In the second step of the study, a NO donor (isosorbide mononitrate) was given to rats 1 h before exhaustive exercise. Mixed-type proteinuria and the elevation in urinary protein levels that occur as a consequence of exhaustive exercise were prevented by NO donor treatment. Finally, in the third step of our study, a calcium channel blocker (diltiazem), another vasodilator, was applied to the rats 1 h before exhaustive exercise. Urinary protein levels were not different in exhausted rats with or without calcium channel blocker treatment. On the other hand, in both groups, urinary protein levels were higher than in the control group. The tail-cuff blood pressure alterations caused by vasodilator drug applications before exercise were not different for NO donor and calcium channel blocker groups. These results suggest that endogenous NO might prevent the postexercise proteinuria from becoming more severe by affecting hemodynamic changes that occur during exercise.

This work has been carried out to evaluate over a short and medium space of time (100 days) the efficacy, tolerance and haemodynamic repercussion of 50 mg of sustained release Isosorbide 5-Mononitrate administered once day to patients with stable effort angina in a random and prospective study, which was double blind crossover and placebo-controlled. In this study we included 10 patients who showed positive exercise test using clinical (angina) and electrocardiographic (ischemic drop of the ST greater than 1 mm) criteria. The assessment was done with cycloergometry starting with 30W and increasing by 20W every 2 minutes until angina appeared accompanied by an ischemic drop of the ST. The effort tests were done basally and at intervals of 4, 12 and 24 hours after the dose. The parameters studied were obtained on the 1st, 25th and 100th days of the study and were compared with those of the placebo. The time taken for the ST to 1 mm to fall (seconds) increased when evaluated after 4 and 12 hours on the 1st, 25th and 100th days in comparison with placebo (p < 0.05). The time taken for angina (seconds) to appear lengthened considerably when evaluated 4 and 12 hours after the dose not only on the 1st day but also on the 25th and 100th days in comparison with placebo (p < 0.05). The duration of the effort (seconds) was significantly greater after 4 and 12 hours on the 1st, 25th and 100th days when compared to that of the placebo (p < 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

imdur heart medication

In a group of 13 patients with severe heart failure, both forced vital capacity (FVC) and forced expiratory volume in 1 s (FEV1) significantly improved after intensive medical therapy (FVC: from 77 +/- 17 to 92 +/- 20%, p < 0.001; FEV1: from 65 +/- 15 to 81 +/- 15%, p < 0.001) in the absence of change in M-mode echo cardiac dimension and left ventricular systolic function; on the other hand, a change of indices of left ventricular filling by Doppler transmitral flow was documented (E/A ratio: from 3.6 +/- 1.2 to 1.65 +/- 1.5, p < 0.01; early filling deceleration time: from 94 +/- 39 to 178 +/- 78 ms, p < 0.01), indicating a reduction of pulmonary capillary pressure; this probably positively affected pulmonary interstitial edema and bronchial wall congestion, thus enhancing pulmonary function.

Systematic review with meta-analyses of randomized trials on IsMn alone or with beta-blockers or endoscopic therapy for oesophageal varices. Electronic and manual searches were combined. Randomized trials on primary and secondary prevention were included. The primary outcome measure was mortality. Intention-to-treat random effects meta-analyses were performed. The robustness of the results was assessed in trial sequential analyses.

imdur medication uses

Differential scanning calorimetry (DSC) is a method which has been applied to obtain thermal information about both raw material and the determination of the content of 5-ISMN in dry mixtures with lactose. The main advantage this offers, compared to other methods, is that it is not necessary to use a standard, it only being necessary to know the data of its fusion heat. HPLC and TLC-densitometry are considered for the determination of 5-ISMN: lactose and pharmaceutical dosage forms. Linearity test, repeatability and accuracy were satisfactory in both methods. Recovery data in pharmaceutical formulations (expressed as the percentage of the label claim) from HPLC and TLC did not give any significant difference (P = 95%). The results show that the chromatographic methods are simple, fast and reliable procedures for the determination of 5-ISMN.

This review contains recent data on the pharmacokinetics and the hemodynamic effects on heart rate and blood pressure of three different groups of drugs (beta-blockers: propranolol; oral nitrates: isosorbide-dinitrate (ISDN), isosorbide-5-mononitrate (IS-5-MN); calcium channel blockers: nifedipine) which were investigated in healthy volunteers or in hypertensive patients after drug application at different times of the day. In the case of IS-5-MN and nifedipine two different galenic formulations were studied. The results clearly demonstrate chronopharmacokinetics for propranolol, ISDN, and the immediate-release formulations of IS-5-MN and nifedipine, whereas no pharmacokinetic daily variations were observed with the sustained-release formulations. However, all drugs exhibited daily variations in their hemodynamic effects. These data greatly support the view that pharmacokinetics and drug effects should be studied simultaneously when chronopharmacologic studies are performed.

Both EVL and drug therapy are effective in the prevention of variceal rebleeding. Comparisons between the two modalities are few, and only in cirrhotics. This prospective randomized controlled trial compared EVL with drug therapy (propranolol + ISMN) in the prevention of rebleeds from esophageal varices in cirrhotic and noncirrhotic portal hypertension (NCPH) patients. One hundred thirty-seven variceal bleeders were randomized to EVL (Group I; n = 71) or drug therapy (Group II; n = 66). In Group I, EVL was done every 2 weeks till obliteration of varices. In Group II, propranolol (dose sufficient to reduce heart rate to 55 bpm/maximum tolerated dose) and ISMN (incremental dose up to 20 mg BD) were administered. Group I and II patients had comparable baseline characteristics, follow-up (12.4 vs. 11.1 months), cirrhotics and noncirrhotics [50(70.4%) and 21(29.6%) vs. 51(77.3%) and 15(22.7%)] and frequency of Child's A (35 vs. 27), B (26 vs. 28), and C (9 vs. 11). The mean daily dose was 109 +/- 46 mg propranolol and 34 +/- 11 mg ISMN and was comparable in cirrhotic and NCPH patients. Upper GI bleeds occurred in 10 patients in Group I (5 from esophageal varices) and in 18 patients in Group II (15 from esophageal varices) (P = 0.06). The actuarial probability of rebleeding from esophageal varices at 24 months was 22% in Group I and 37% in Group II (P = 0.02). The probability of bleed was significantly higher in Child's C compared to Child's A/B cirrhotics (P = 0.02). On subgroup analysis, in NCPH patients, the actuarial probability of bleed at 24 months was significantly lower in Group I compared to Group II (25% vs 37%; P = 0.01). In cirrhotics, there was no difference in the probability of rebleeding between patients in Group I and those in Group II (P = 0.74). In Group II, 25.7% patients had adverse effects of drug therapy and 9% patients had to stop propranolol due to serious adverse effects, none required stopping ISMN. There were 10 deaths, 6 in Group I (bleed related, 1) and 4 in Group II (bleed related, 1); the actuarial probability of survival was comparable (P = 0.39). EVL and combination therapy are equally effective in the prevention of variceal rebleeding in cirrhotic patients. EVL is more effective than drug therapy in the prevention of rebleeds in patients with NCPH and, hence, recommended. However, in view of the small number of NCPH patients, further studies are needed before this can be stated conclusively.

The objective of this study was to compare NO-donor isosorbide mononitrate to misoprostol, both applied as vaginal tablets for cervical ripening prior to first trimester curettage in patients with missed abortion.

imdur 30 mg

Extended release formulations of isosorbide mononitrate (IMN), based on osmotic technology, were developed. Target release profile was selected and different variables were optimized to achieve the same. Formulation variables like type (PVP, PEG-4000, and HPMC) and level of pore former (0-55%, w/w of polymer), percent weight gain were found to affect the drug release from the developed formulations. Drug release was inversely proportional to the membrane weight but directly related to the initial level of pore former in the membrane. Burst strength of the exhausted shells was inversely proportional to the level of pore former, but directly affected by the membrane weight. Satisfactory burst strength (more than 320 g) was obtained when PVP was used as pore former (up to 55%, w/w of polymer) at the membrane weight of 7.5% and more. The release from the developed formulations was independent of pH and agitational intensity, but dependent on the osmotic pressure of the release media. Results of SEM studies showed the formation of pores in the membrane from where the drug release occurred. The formulations were found to be stable after 3 months of accelerated stability studies. Prediction of steady-state levels showed the plasma concentrations of IMN to be within the desired range.

Twenty-six patients with coronary artery disease who had fixed segmental defects on exercise-rest-Tl-201 imaging were studied. All of them underwent Tl-201 reinjection study. Within 1 week of Tl-201 imaging, rest-Tc99m MIBI imaging was performed after sublingual 5 mg ISDN administration (2-day protocol). For each study, tomograms were divided into 20 segments based on three short-axis slices, one vertical long-axis representing the totality of the left ventricle and regional tracer uptake was quantitatively analyzed. Regional tracer uptake was evaluated in 20 myocardial segments for all patients. Viability was defined as presence of tracer uptake >/=50% of peak activity on each study. A total 520 myocardial segments were assessed by semi quantitative analysis.

Progress in the investigations upon factors influencing the course of the ischemic heart disease focused our attention on the deformability of erythrocytes. That attribute of the red blood cells (RBC) is described by their susceptibility to changes in shape without changing volume. Because of that feature, RBC can reach the smallest capillaries of the circulatory system. The aim of the study was to determine the influence of mononitrates (Olicard Ret.) on the deformability of RBC (EDI) in correlation to the clinical course of the ischemic heart disease and to evaluate the role of catecholamines in the course of the disease and their influence upon EDI. 30 patients (pts) treated with mononitrates for 4 weeks were enrolled into the study. In 27 pts clinical improvement was recorded, as evaluated by the results of repeated exercise tests buy imdur and changes in the number of anginal attacks. Mean weekly number of anginal attacks decreased from 6.2 to 2.1 (p < 0.05), and parameters of exercise tests improved: DP/Wmac decreased from 0.694 to 0.479 (p < 0.001) and maximal workload attained increased from 6.8 to 9.0 METS (p < 0.001). Correspondingly to the clinical improvement, beneficial changes in RBC deformability were seen: 0.033 vs 0.040 (p < 0.01). Correlation factor for changes in EDI (r = 0.628) was higher than that for the number of anginal attacks (r = 0.589), but lower than the correlation factor for exercise test parameters (r = 0.969 for DP/Wmax and r = 0.858 for METS). There were no significant changes in the urinary output of catecholamines and no correlations were seen between urinary output of adrenaline, noradrenaline and EDI.(ABSTRACT TRUNCATED AT 250 WORDS)

This study investigated the effects of nitrate on bone mineral density (BMD) and bone marrow perfusion in ovariectomized (OVX) female rats, and also the effects of nitrate on in vitro osteoblastic activity and osteoclastic differentiation of murine monocyte/ macrophage RAW 264.7 cells. Female Sprague-Dawley rats buy imdur were divided into OVX + nitrate group (isosorbide-5-mononitrate, ISM, 150 mg/kg/ day b.i.d), OVX + vehicle group, and control group. Lumbar spine CT bone densitometry and perfusion MRI were performed on the rats at baseline and week 8 post-OVX. The OVX rats' BMD decreased by 22.5% ± 5.7% at week 8 (p < 0.001); while the OVX + ISM rats' BMD decreased by 13.1% ± 2.7% (p < 0.001). The BMD loss difference between the two groups of rats was significant (p = 0.018). The OVX rats' lumbar vertebral perfusion MRI maximum enhancement (Emax) decreased by 10.3% ± 5.0% at week 8 (p < 0.005), while in OVX + ISM rats, the Emax increased by 5.5% ± 6.9% (p > 0.05). The proliferation of osteoblast-like UMR-106 cells increased significantly with ISM treatment at 0.78 µM to 50 μM. Treatment of UMR-106 cells with ISM also stimulated the BrdU uptake. After the RAW 264.7 cells were co-treated with osteoclastogenesis inducer RANKL and 6.25 μM ~ 100 μM of ISM for 3 days, a trend of dose-dependent increase of osteoclast number was noted.

In some patients with chronic stable angina the beneficial effects of nitrates may result not only from a reduction in venous return, but also from their action on coronary circulation. In buy imdur these patients, rate-pressure product at ischemia (RPPI) increases to > 2500 bpm x mmHg after sublingual nitrates (SLN). The relative susceptibility of the venous system and the coronary circulation to the development of nitrate tolerance and the effects of two different drug schedules on the development of tolerance were investigated in patients with these characteristics.

The major aim of this study was to prepare isosorbide-5-mononitrate (5-ISMN) sustained-release pellets and evaluate their stability. The pellets were prepared by extrusion/spheronization, and then the core pellets were coated with ethylcellulose (EC 10cp) and Eudragit(®)NE30D. Here, EC was used as the subcoating agent while Eudragit(®)NE30D acted as the outer-coating agent. 5-ISMN sustained-release pellets as a novel drug delivery system contained the immediate-release portion in the outer-coating layer. Unexpectedly, 5-ISMN was found to migrate from the interior of the pellets to the surface forming needle crystals and exhibited the phenomenon of sublimation, which resulted in a tremendous increase in the release rate buy imdur . Our research showed that the migration and sublimation of the active ingredient was related to the temperature and humidity. Polyvinylpyrrolidone (PVP K30) can affect the precipitation of 5-ISMN by forming a charge transfer complex between the drug and PVP, while hydroxypropyl methyl cellulose (HPMC E5) had no effect, and confirmed the correctness of this view through photographs and IR spectra. In the investigation of the stability, the results showed that there was no sublimation and migration while the pellets stored at 25°C/60%RH (ambient conditions) and 40°C/75% RH (stress conditions) during a 6-month period.

Our study was aimed to evaluate the hypotensive effects of a single dose of 100 mg IS-5-MN (Mack) using ambulatory blood pressure monitoring (ABPM). We have enrolled into the study 50 patients. Twenty-one of them were hypertensive (WHO-class I and II) and twenty nine were normotensive. The mean age of the patients was 52.88 +/- 12 years. ABPM was performed during 48 hours. After first 24 hours without any hypotensive drugs the IS-5-MN or placebo was given in double blind study. The readings in the second 24 hours were taken in the same procedure as in the first 24 hours i.e. every twenty minutes between 7.00 and 23.00 every half an hour between 23.00 and 7.00. Mean hourly systolic (SBP) and diastolic (DBP) blood pressures of the first day (without any treatment) and 2nd day (IS-5-MN or placebo) were compared in four group of patients:1. Hypertensives receiving placebo, 2. Hypertensives receiving IS-5-MN, 3. Normotensives receiving placebo and 4. Normotensives receiving IS-5-MN. Only in the fourth group of patients mean hourly blood pressures from the day 2 were significantly lower than from the day I. First hypotensive effects for SBP as well as for DBP were observed four hour after IS-5-MN was given. These effects last about buy imdur 8 hours. These data confirm the hypotensive effects of mononitrates in normotensive patients.

In elderly patients with systolic hypertension resistant to treatment with conventional therapy, increased aortic pulse wave reflection and a high augmentation index are often present. These findings are indicative of endothelial dysfunction and deficient generation of nitric oxide, a potent vasodilator in the arterial tree. In such patients, treatment with the nitric oxide donor extended-release isosorbide mononitrate characteristically produces prompt and sustained falls in both pulse wave reflection and systolic blood pressure. The adjunct use of this nitrate produces useful additional decreases in systolic blood pressure ranging from 10 to 45 mm Hg, often achieving target blood pressure goals in isolated systolic hypertension. By combining this endothelium-independent nitric oxide donor with angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers, buy imdur the potential exists to address both the nitric oxide deficiency and endothelial dysfunction of the vascular endothelium in these patients. Other possibilities for synergism with this combination include complementary hemodynamic, circadian, and metabolic actions together with prevention of nitrate tolerance. Isosorbide mononitrate may also be used successfully with calcium channel blockers, beta blockers, and diuretics.

Chronic therapy with either ISMN or TD buy imdur -NTG is associated with development of vascular tolerance. Despite the induction of vascular tolerance, platelet responsiveness to NTG and SNP remains unaffected. Therefore, development of vascular tolerance is unlikely to compromise the anti-aggregatory effects of organic nitrates, or those of endogenous NO.

Imdur contains isosorbide-5-mononitrate (IS-5-MN) in a controlled-release (Durules) formulation. It has a significant anti-anginal effect when taken once daily at a dose of 60 mg. This anti-anginal effect persists during long-term treatment without the development of tolerance; once-daily treatment produces a plasma nitrate profile that is high enough to give anti-anginal protection during the daytime, but low enough during the latter part of the dosage interval to avoid the development of tolerance. Evidence shows that once-daily Imdur is equivalent in efficacy to plain tablets of IS-5-MN and isosorbide dinitrate taken three times daily at the same total daily buy imdur dosage (60 mg), and to the calcium antagonist diltiazem (60 mg three times daily). In addition, the anti-anginal protection provided by Imdur in combination with beta-blocker treatment is superior to that achieved with beta-blocker treatment alone. In long-term studies Imdur has been shown to be well tolerated.

In the large-scale trial, Gruppo Italiano per lo Studio della Sopravvivenza nell'Infarto Miocardico-3 (GISSI-3), patients receiving the combination of lisinopril and glyceryl Singulair 5 Mg trinitrate benefited most from experimental therapy. Therefore, a multicenter, randomized, double-blind study, Delapril Remodeling After Acute Myocardial Infarction (DRAMI), was designed to assess (1) the possible additive beneficial effect on left ventricular remodeling of nitrates when combined with an angiotensin-converting enzyme inhibitor (ACEI), and (2) the tolerability of a new ACEI, delapril, in respect to lisinopril in patients with large myocardial infarction (MI).

Thirty episodes of first upper bleeding occurred; 16 were in the Is-5-Mn group. Actuarial probability of bleeding did not differ between the two groups. Endoscopic variceal red signs were the only independent predictors of early bleeding. Of the 52 patients who died, 28 were in the Is-5-Mn group. The likelihood of death was greater among patients assigned to Is-5-Mn than to Pro, but only in patients older than 50 Effexor 75mg Generic years (72% vs. 48% at 6 years; P = 0.006). Child-Pugh score, bleeding, age, and assignment to Is-5-Mn were independent predictors of death. The likelihood of death without bleeding was also higher (P = 0.05) in the Is-5-Mn group.

58,050 patients entering 1086 hospitals up to 24 h (median 8 h) after the onset of suspected acute myocardial infarction (MI) with no clear contraindications to the study treatments (in particular, no cardiogenic shock or persistent severe hypotension) were randomised in a "2 x 2 x 2 factorial" study. The treatment comparisons were: (i) 1 month of oral captopril (6.25 mg initial dose titrated up to 50 mg twice daily) versus matching placebo; (ii) 1 month of oral controlled-release mononitrate (30 mg initial dose titrated up to 60 mg once daily) versus matching placebo; and (iii) 24 h of intravenous magnesium sulphate (8 mmol initial bolus followed by 72 mmol) versus open control. There were no significant "interactions" between the effects of these three treatments, and the results for each are based on the randomised comparison of about 29,000 active versus 29,000 control allocated patients. Captopril There was a significant 7% (SD 3) proportional reduction in 5-week mortality (2088 [7.19%] captopril-allocated deaths vs 2231 [7.69%] placebo; 2p = 0.02), which corresponds to an absolute difference of 4.9 SD 2.2 fewer deaths per 1000 patients treated for 1 month. The absolute benefits appeared to be Tofranil Medicine larger (perhaps about 10 fewer deaths per 1000) in certain higher-risk groups, such as those presenting with a history of previous MI or with heart failure. The survival advantage appeared to be maintained in the longer term (5.4 [SD 2.8] fewer deaths per 1000 at 12 months). Captopril was associated with an increase of 52 (SD 2) patients per 1000 in hypotension considered severe enough to require termination of study treatment, of 5 (SD 2) per 1000 in reported cardiogenic shock, and of 5 (SD 1) per 1000 in some degree of renal dysfunction. It produced no excess of deaths on days 0-1, even among patients with low blood pressure at entry. Mononitrate There was no significant reduction in 5-week mortality, either overall (2129 [7.34%] mononitrate-allocated deaths vs 2190 [7.54%] placebo) or in any subgroup examined (including those receiving short-term non-study intravenous or oral nitrates at entry). Further follow-up did not indicate any later survival advantage. The only significant side-effect of the mononitrate regimen studied was an increase of 15 (SD 2) per 1000 in hypotension. Those allocated active treatment had somewhat fewer deaths on days 0-1, which is reassuring a bout the safety of using nitrates early in acute MI.(ABSTRACT TRUNCATED AT 400 WORDS)

Thirty-two hospitalized patients with angiographically-documented coronary artery disease and stable angina pectoris (NYHA class III) were randomly assigned to one of four treatment groups. After a one-week washout period, baseline examinations (systolic time intervals, blood pressure and exercise ECG) were performed. The patients were then treated with either 20 mg isosorbide dinitrate in sustained-release form (sustained-release ISDN), 20 mg isosorbide 5-mononitrate (IS 5-MN), 2.5 mg buccal nitroglycerin in sustained-release form (NTGB) or 6.5 mg oral nitroglycerin in sustained-release form (NTGO) and one hour thereafter, the heart rate, blood pressure and systolic time intervals were determined. Subsequently, the patients were treated with the respective nitrates four times daily for two weeks. On the seventh and 14th days, the heart rate, blood pressure and systolic time intervals were again determined before and after the first dose of the day. Additionally, after the first dose on the 14th day, an exercise ECG was performed. The effect of the nitrates on the venous capacitance system is reflected by the increase in the PEP/LVET ratio where NTGO and NTGB elicited marked actions and those of sustained-release ISDN and IS 5-MN were of a lesser extent. An effect on systolic and diastolic blood pressure at rest and during exercise could be documented only after administration of NTGB. The anti-ischemic effect of the nitrates was based on the reduction of ST-segment depression during exercise; after two weeks of treatment, sustained-release ISDN and IS 5-MN were associated with complete tolerance development while NTGO continued to exert a slight, and NTGB a clear reduction in ST-segment depression. Personal protocols documented that nitrate consumption and rate of anginal attacks during longterm treatment were unaffected by sustained-release ISDN, IS 5-MN and NTGO, but Zantac 150 Dosage were reduced by 50% while on treatment with NTGB.

Hepatic extraction of organic nitrates, including Viagra Compare Cost that of isosorbide dinitrate (ISDN), has been thought to be nearly complete in man but has never been directly measured. We examined the time course of plasma ISDN and metabolite concentrations in arterial and hepatic venous blood in four cardiac patients receiving an intravenous ISDN infusion. Apparent hepatic extraction of ISDN was high (90%) at the beginning of infusion but fell to about 44% 1 hr after termination of infusion. The decrease in ISDN concentration gradient across the liver correlates with an increase in plasma isosorbide-5-mononitrate concentration, but a cause-and-effect relationship resulting from metabolite inhibition cannot be established. The time-averaged hepatic extraction of ISDN, at about 70%, agreed with its oral bioavailability in patients.

In an open clinical trial 19 patients with angina pectoris (functional class Cipro Dosage II-III) received in turn either non-retard tablets of isosorbide dinitrate (nitrosorbid, cardiket) in a mean dose 80 mg/day or isosorbide 5-mononitrate (mono mac) in a mean dose 51.5 mg/day. Each drug was given for a month. The effect was assessed by changes in frequency of anginal attacks and exercise tolerance. Non-retard isosorbide dinitrate and isosorbide 5-mononitrate demonstrate a good antiischemic effect, are safe and well tolerated. Isosorbide dinitrate and mononitrates do not differ significantly in reduction of the anginal attacks and by an increase in exercise tolerance but the effective dose of mono mac was 1.5-2 times less than that of nitrosorbide or cardiket, thus it is more cost-effective.

The aortic pulse wave contour in isolated systolic hypertension often shows a prominent reflection peak, which combines with the incident wave arising from cardiac ejection so as to widen pulse pressure. We investigated the effects of an extended-release nitrate preparation and of 2 angiotensin II (AII) inhibitors (an AII receptor antagonist and an ACE inhibitor) on the aortic pulse wave contour and systemic blood pressure in hypertensive subjects with high augmentation index caused by exaggerated pulse wave reflection. Two double-blind, randomized, placebo-controlled crossover studies were carried out in a total of 16 elderly patients with systolic hypertension resistant to conventional antihypertensive therapy. In 1 study, pharmacodynamic responses to single doses of placebo, isosorbide mononitrate, Betnovate Dose eprosartan, and captopril were determined; in the other, single-dose isosorbide mononitrate and placebo were compared in subjects treated with AII inhibitors at baseline. Blood pressure was measured by sphygmomanometry and pulse wave components by applanation tonometry at the radial artery. All 3 agents were shown to decrease brachial systolic blood pressure, aortic systolic blood pressure, and aortic pulse pressure. Qualitative effects on the aortic pulse wave contour differed: augmentation index was not significantly altered by either captopril or eprosartan but was decreased (P<0.0001) by approximately 50% of the placebo value with isosorbide mononitrate in both study groups. We propose that isosorbide mononitrate corrected the magnified wave reflection in systolic hypertension of these elderly patients by an effect that was distinct from that exercised by either acute or chronic AII inhibition.

A capsule formulation containing 50 mg of isosorbide mononitrate has been developed, 30% of which is in a nonsustained-release form to ensure rapid attainment of initial plasma levels. The remaining 70% is in a sustained-release form that ensures a long-lasting effect and the convenience of once-daily dosing. This formulation of sustained-release isosorbide mononitrate (Elantan LA 50 mg) provides plasma levels greater than 100 ng/ml for 17 hours after oral administration. For the remaining 7 hours, the nitrate plasma level ranges between 50 and 100 ng Imdur 60mg Tablets /ml.

Twelve trials were included (6 BL vs. PT, 4 BL+PT vs. BL, 2 BL+PT vs. PT). All trials used beta-blockers +/- isosorbide mononitrate (ISMN) as PT. Mortality was not significantly different among trials. Rebleeding was not significantly different for BL vs. PT (RR 1.00, 95% CI 0.73-1.37). BL reduced rebleeding compared with PT for trials with mean beta-blocker dose <80 mg/day (RR 0.67, 95% CI 0.49-0.91). There were nonsignificant differences in rebleeding for BL+PT vs. BL (RR 0.57, 95% CI 0.31-1.08) and BL+PT vs. PT (RR 0.76, 95% CI 0.56-1.03). There was no difference in adverse events between BL vs. PT, but was higher with BL+PT vs. BL.

L-isoidide mononitrate (L-IIMN) is the most potent mononitrate vasodilator described so far in the literature. Since other mononitrates, such as isosorbide-5-mononitrate and isosorbide-2-mononitrate, have been shown not to be subject to first-pass metabolism, we examined the pharmacokinetics of L-IIMN after oral administration to determine whether this compound also exhibited this behavior. An oral dose of 2 mg kg-1 L-IIMN dissolved in normal saline was given to seven rats. Absorption of L-IIMN after dosing was rapid with an apparent absorption half-life of 9.5 +/- 3.6 min (mean +/- SD). Plasma L-IIMN concentrations peaked between 5 and 20 min after dosing and declined thereafter in an apparently monoexponential manner. The average elimination half-life was 11.9 +/- 1.7 min (mean +/- SD). Oral bioavailability was estimated to be about 50%. Thus, unlike the other mononitrates so far examined in the literature, L-IIMN exhibits incomplete bioavailability. This pharmacokinetic behavior, however, is consistent with its faster systemic clearance compared to other organic mononitrates.

In Group 1 patients delta LVA 2 and delta RPPI 2 showed values which were similar to delta LVA 1 and delta RPPI 1 (mean value delta LVA 2 47 vs mean delta LVA 1 48.2 pixels, p = ns; mean value delta RPPI 2 5264 vs mean delta RPPI 1 5536 bpm x mmHg, p = ns). These results suggest that Group 1 patients did not develop tolerance either at the coronary or at the venous level. In Group 2 patients, delta LVA 2 was significantly lower than delta LVA 1 (mean delta LVA 2 18.4 vs mean delta LVA 1 54 pixels, p < 0.01). This finding indicated tolerance to nitrates at the venous level. On the other hand, in all Group 2 patients, values of delta RPPI 2, though lower than delta RPPI 1 (mean delta RPPI 2 3095 vs mean delta RPPI 1 6083 bpm x mmHg, p < 0.01) were still higher than 2500 bpm x mmHg, indicating that the effect of nitrates at the coronary level was preserved. These data suggest that in patients treated with high doses of nitrates, the effect of these drugs at the coronary level is still present when tolerance has already developed at the venous level.

This demonstrated that propranolol reduced both portal pressure gradient (7.7 +/- 2.3 to 5.5 +/- 2.1 mmHg, P < 0.01) and portal vein flow (925 +/- 123 to 597 +/- 99 mL/min, P = 0.01) significantly, implying a reduction in splanchnic inflow as its main effect. In contrast, isosorbide-5-mononitrate tended to increase portal vein flow (814 +/- 186 to 911 +/- 211 mL/min; P = 0.06) whilst reducing portal pressure significantly (108 +/- 12 to 92 +/- 10 mmHg P = 0.014). This suggests a fall in intrahepatic resistance and provides no evidence for baroreceptor-mediated reflex splanchnic vasoconstriction.
