lanoxin 500 mg

Immunoreactive digoxin-like activity was found in the Chinese medicine, KYUSHIN tablet, taken popularly in Japan without prescription. The antibodies used in the assays of digoxin reacted with Ch'an-su, the major effective component of KYUSHIN, which contained cardiotonic steroids with a chemical structure similar to that of digoxin. One tablet of KYUSHIN had digoxin-like immunoreactivity equivalent to 1.9 micrograms. (TDx analyzer), 1.5 micrograms (Du Pont aca analyzer) and 72 micrograms digoxin (Enzymun-Test, Boehringer). These different equivalencies may be attributed to differences in cross-reactivity of the antibody used in the immunoassays. Two healthy volunteers took two KYUSHIN tablets three times a day, a typical dose, and digoxin-like immunoreactivity reached almost 0.4 microgram/l in 0.5 day. Recently, a competitive digoxin chemiluminescent immunoassay has been developed by Ciba Corning ACS 180. The assay utilizes an acridinium-ester labelled mouse monoclonal digoxin antibody as the tracer. In the extracted solution of KYUSHIN and serum after administration of two tablets, the digoxin-like immunoreactivity value on the Ciba Corning ACS 180 digoxin assay was < 0.10 microgram/l (off-range low). Therapeutic drug monitoring should be interpreted carefully in patients taking Chinese medicines, many of which contain the Ch'an-su component.

Chronic systemic hypertension causes cardiac pressure overload leading to increased myocardial O(2) consumption. Hypoxia-inducible factor 1 (HIF-1) is a master regulator of O(2) homeostasis. Mouse embryos lacking expression of the O(2)-regulated HIF-1α subunit die at midgestation with severe cardiac malformations and vascular regression. Here we report that Hif1a(f/f);Tie2-Cre conditional knockout mice, which lack HIF-1α expression only in Tie2(+) lineage cells, develop normally, but when subjected to pressure overload induced by transaortic constriction (TAC), they manifest rapid cardiac decompensation, which is accompanied by excess cardiac fibrosis and myocardial hypertrophy, decreased myocardial capillary density, increased myocardial hypoxia and apoptosis, and increased TGF-β signaling through both canonical and noncanonical pathways that activate SMAD2/3 and ERK1/2, respectively, within endothelial cells of cardiac blood vessels. TAC also induces dilatation of the proximal aorta through enhanced TGF-β signaling in Hif1a(f/f);Tie2-Cre mice. Inhibition of TGF-β signaling by treatment with neutralizing antibody or pharmacologic inhibition of MEK-ERK signaling prevented TAC-induced contractile dysfunction and pathological remodeling. Thus, HIF-1 plays a critical protective role in the adaptation of the heart and aorta to pressure overload by negatively regulating TGF-β signaling in endothelial cells. Treatment of wild-type mice with digoxin, which inhibits HIF-1α synthesis, resulted in rapid cardiac failure after TAC. Although digoxin has been used for decades as an inotropic agent to treat heart failure, it does not improve survival, suggesting that the countertherapeutic effects of digoxin observed in the TAC mouse model may have clinical relevance.

The isoprenoid pathway produces three key metabolites--digoxin (membrane sodium-potassium ATPase inhibitor and regulator of neurotransmitter/aminoacid transport), dolichol (regulates N-glycosylation of proteins) and ubiquinone (free radical scavenger). This was assessed in patients with essential hypertension, familial hypotension, acute coronary artery disease and acute thrombotic strokes. The pathway was also assessed in patients with right hemispheric, left hemispheric and bihemispheric dominance for comparison. In patients with acute coronary artery disease, acute thrombotic stroke, essential hypertension and right hemispheric dominance, there was elevated digoxin synthesis, increased dolichol and glycoconjugate levels and low ubiquinone and high free radical levels. There was also an increase in tryptophan catabolites, reduction in tyrosine catabolites, increase in cholesterol-phospholipid ratio and a reduction in glycoconjugate level of RBC membrane in this group of patients as well as in those with right hemispheric dominance. In patients with familial hypotension and left hemispheric dominance, the patterns were reversed. The role of a dysfunctional isoprenoid pathway and endogenous digoxin in the pathogenesis of essential hypertension and familial hypotension and in thrombotic vascular disease in relation to hemispheric dominance is discussed.

Irish Wolfhound dogs were prospectively randomized to receive pimobendan (Vetmedin®), benazepril HCl (Fortekor®), or methyldigoxin (Lanitop®) monotherapy in a 1:1:1 ratio in a blinded clinical trial. The prospectively defined composite primary endpoint was onset of CHF or sudden death. To assure stringent evaluation of treatment effect, data from dogs complying with the study protocol were analyzed.

With the increasing number of implantable cardioverter-defibrillator (ICD) implantations in patients with sustained ventricular tachyarrhythmias, there is a growing interest in typical complications associated with this therapy. We analyzed the reasons and the incidence of inadequate therapy deliveries in 100 patients with epicardial (n = 27) or transvenous (n = 73) ICDs during a follow-up period of 10 +/- 8 months. A total of 21 of 100 patients received inadequate therapies. The most common reason was sinus tachycardia in eleven patients. Additional unnecessary shocks were avoided by reprogramming and application of beta-blockers. Lead failures caused the erroneous detection and defibrillation of ventricular fibrillation without any preceding clinical symptoms in four patients with an epicardial and in one patient with a transvenous ICD. All patients underwent successful surgical revision of their system. Atrial fibrillation with rapid ventricular response triggered inadequate shocks in four patients. Following digoxin administration no patient had additional inadequate shocks. In one patient non-sustained tachycardias caused unnecessary defibrillations. These results demonstrate that inadequate defibrillations are a common complication in patients after ICD-placement. The performance of x-ray, stress testing, and Holter monitoring on a regular basis may facilitate early diagnosis of possible reasons for unnecessary therapy deliveries. The improvement of detection and memory functions in future ICD-generations appears to be mandatory as well.

lanoxin dosage range

Using four different digoxin kits, it was disclosed that the majority of various samples including amniotic fluid, cord blood, and serum from neonates contained substantial levels of digoxin-like immunoreactive substance. The differences in data seemed to be due to the range of epitopes which are recognized by antidigoxin antiserum. The day-to-day studies on sera serially obtained from infants at birth to 48 days old revealed that the level of the substance (0.31 +/- 0.12 ng/ml) in sera of the 1-day-old neonates rapidly declined to the level of 0.1 ng/ml by the 2nd postnatal wk and thereafter gradually declined. The immunological specificity and accuracy of the detection of digoxin-like immunoreactive substance was confirmed by a sample dilution test, a recovery test for standard digoxin, and an absorption test with antidigoxin antiserum. The amniotic fluid and cord blood also contained four to eight times more of a digitoxin-like immunoreactive substance than they did digoxin-like immunoreactive substance. A significant correlation was observed between the levels of digoxin-like immunoreactive substance and of digitoxin-like immunoreactive substance (p less than 0.01).

Since we have previously shown that the ratio of the 17.5-/22-kDa GH1 transcripts correlates with severity of the IGHD II phenotype, our findings here suggest that selected previously unconsidered agents could possibly reduce the severity of IGHD II, while other agents could possibly exacerbate the disease phenotype.

lanoxin overdose death

A digoxin-like immunoreactive substance (DLIS) has been reported in the amniotic fluid. Since radioimmunoassay kits are standardized using serum-based standards, we hypothesized that measurement of DLIS may be an artifact related to the low protein content of amniotic fluid. We analyzed 12 amniotic fluid samples before and after supplementation with lyophilized human serum. The means +/- SDs for DLIS (nmol/l) at protein concentrations of 0, 32 and 63 g/l were 1.4 +/- 0.16, 0.6 +/- 0.09, and 0.4 +/- 0.09 nmol/l, respectively. We, therefore, hypothesize that DLIS in amniotic fluid may in part be explained by a technical artifact.

Sensory neurons mediate diabetic peripheral neuropathy. Using a mouse model of diabetic peripheral neuropathy (BKS.Cg-m+/+Lepr(db)/J (db/db) mice) and cultured dorsal root ganglion (DRG) neurons, the present study showed that hyperglycemia downregulated miR-146a expression and elevated interleukin-1 receptor-activated kinase (IRAK1) and tumor necrosis factor receptor-associated factor 6 (TRAF6) levels in DRG neurons. In vitro, elevation of miR-146a by miR-146a mimics in DRG neurons increased neuronal survival under high-glucose conditions. Downregulation and elevation of miR-146a in DRG neurons, respectively, were inversely related to IRAK1 and TRAF6 levels. Treatment of diabetic peripheral neuropathy with sildenafil, a phosphodiesterase type 5 inhibitor, augmented miR-146a expression and decreased levels of IRAK1 and TRAF6 in the DRG neurons. In vitro, blockage of miR-146a in DRG neurons abolished the effect of sildenafil on DRG neuron protection and downregulation of IRAK1 and TRAF6 proteins under hyperglycemia. Our data provide the first evidence showing that miR-146a plays an important role in mediating DRG neuron apoptosis under hyperglycemic conditions.

During the hospital stays, 192 ADRs were identified in 183 patients (5.8% of the sample). Cardiovascular and arrhythmic complications (20.3% of all ADRs) were the most frequent ADRs, followed by gastrointestinal (18.8%), dermatologic and allergic (12.5%), hemorrhagic (11.5%), and electrolyte (9.9%) disturbances. Adverse drug reactions were recorded in 101 (7.4%) of 1363 depressed patients and in 82 (4.6%) of 1771 nondepressed patients (P =.001). After adjusting for potential confounders, depression was associated with a significantly higher rate of ADRs (odds ratio, 1.58; 95% confidence interval, 1.14-2.20; P =.006). This effect seemed more pronounced in women (odds ratio, 1.85; 95% confidence interval, 1.16-2.95) than in men (odds ratio, 1.38; 95% confidence interval, 0.85-2.34).

Overall 75 patients with rheumatic mitral heart disease were examined for the effect of the clinical and echocardiography characteristics of central and intracardiac hemodynamics on the efficacy of the use of digoxin. The development of digoxin resistance in patients with the predominance of stenosis of the mitral opening depended to the greatest degree on the duration of heart decompensation, area of the mitral opening and duration of the phase of left ventricle relaxation; in patients with the predominance of mitral insufficiency, it depended on the level of endosystolic stress, pressure of left ventricle filling and duration of the phase of isometric left ventricle contraction. Based on the calculation of the information content of the parameters under study, a prognostic table was made. The use of the table allowed forecasting the development of glycoside resistance in 77.6% of cases.

Studies in the fetal lamb have shown that atrial pacing beyond a rate of 300-320 beats/min may be associated with dramatic changes of venous blood velocity waveforms, an increase of venous pressure by up to 75%, hydrops, polyhydramnios and placental edema. The aim of our study was to determine the 'critical' heart rate frequency in the human fetus. In 11 fetuses (five with and six without hydrops) with supraventricular tachycardia, pulsed wave Doppler analysis of flow velocity waveforms of the inferior vena cava, the ductus venosus and the left hepatic vein were performed before and after drug treatment. In ten cases cardioversion was achieved by in utero antiarrhythmic drug therapy; in one case treated with digoxin and flecainide the supraventricular tachycardia was decreased to 160-190 beats/min with disappearance of hydrops. Before intrauterine treatment of supraventricular tachycardia, pulsatile reversal of blood flow in the inferior vena cava, ductus venosus and left hepatic vein was visible, with monophasic forward flow during systole and reversed flow during diastole in ten of 11 fetuses. One fetus with supraventricular tachycardia of 195 beats/min showed a normal biphasic forward flow pattern. During drug-induced sinus rhythm, a normal biphasic forward venous blood flow pattern was shown in all ten cases. In five cases pulsatile reversal was demonstrated during a drug-induced reduction of the heart rate from 280 to 210 beats/min and a normal biphasic forward flow velocity waveform appeared during supraventricular tachycardia below 210 beats/min.(ABSTRACT TRUNCATED AT 250 WORDS)

Hawthorn is an herb indicated for treating cardiac illness. Because a patient taking digoxin may also take hawthorn, we investigated potential interference of hawthorn in serum digoxin measurements using immunoassays as well as pharmacodynamic interaction between hawthorn and digoxin. Hawthorn contains alkaloids that are structurally similar to digoxin and may interfere with serum digoxin measurement using immunoassays. In addition, hawthorn has cardioactive properties similar to digoxin.

lanoxin medication 2016-06-23

To investigate whether measuring levels of digoxin in patients with idiopathic dilated cardiomyopathy (IDC) is helpful in dose adjustment of digoxin we did the following study. In 77 patients (63 male, 14 female) with invasively verified IDC serum-digoxin levels were buy lanoxin measured after a treatment period with beta-acetyldigoxin of at least 6 months. All patients received digoxin, 76 had ACE-inhibitors and 69 used diuretics. Mean serum-levels of digoxin were 0.96 ng/ml while using a mean daily dose of digoxin of 0.24 mg. Those who showed a serum level of digoxin within the recommended range took a slightly higher daily dose of digoxin when compared to those with low levels of digoxin (0.26 vs. 0.23 mg/day, p < 0.05). Therefore, we conclude that low serum-levels of digoxin are mainly caused by low intake of digoxin and it is justified to measure digoxin-levels in IDC-patients even if it increases costs.

Our data suggest that gastric acidity causes the breakdown of digoxin to products that cross-react in the assay (EIA) that is commonly used clinically. In patients with reduced gastric acidity, increased plasma concentrations of unchanged digoxin may not be buy lanoxin detected because of limitations of the EIA, which may invalidate the quantitative use of the plasma digoxin concentration as a predictor of digoxin toxicity. Omeprazole, and presumably other gastric-acid inhibitors, may increase the bioavailability of unchanged digoxin.

It was examined whether the digoxin-like immunoreactive substance (DLIS buy lanoxin ) extracted from cord blood has a natriuretic activity. The DLIS was prepared from cord blood of healthy fullterm infants by acetone-HCl extraction and a gel filtration column. A solution (solution A) containing 1.0 ng/ml of DLIS or another solution (solution B) consisting of solution A from which the DLIS had been completely absorbed by rat brain synaptosome, a crude digoxin receptor, were infused directly into the renal arteries of rats. Serum and urine were serially sampled. The excretion of sodium into the urine increased gradually after the initiation of infusion and reached a level two or three times higher than that before infusion (p less than 0.05). The infusion of a buffer solution or of the extract from which the DLIS had been absorbed by rat brain synaptosome did not significantly increase the urinary excretion of sodium. Statistical analysis showed a clear difference in the natriuretic activity between solutions A and B (p less than 0.01, p less than 0.05). Well-known natriuretic substances such as atrial natriuretic hormone, prostaglandin E2, F2 alpha, bradykinin and oxytocin dopamine were not detected enough to contribute to natriuresis in the extracts. From this data, we speculated that the DLIS in cord blood has a natriuretic activity and that it plays a role in water and sodium homeostasis in perinatal life.

Compared with placebo, digoxin resulted in an increase in RR-interval (p < 0.0001), a decrease in ST-segment and T-wave amplitude (p = 0.009 and p = 0.002, respectively), and in the QTc interval (p = 0.01). These changes were present 2 h after the first dose, but were more buy lanoxin pronounced after 16 h. There was no significant correlation between serum concentration of digoxin and ECG changes at 16 h.

We measured the activity of the Na,K ATPase, Mg dependent and inhibited by ouabain, in microsomal fractions obtained from guinea pig myocardium and kidney, as weel as red cell ghosts. A group of animal was treated with beta-methyl digoxin (0.2 mg intraperitoneally) about one hour before obtaining the tissues. The control group received no medication. The plasma of both group, control and treated, had similar potassium concentrations (4.3 +/- 0.87 mM and 4.3 +/- 0.66 mM, respectively). The plasma digoxin concentrations from treated animals was always high (76.4 +/- 34.1 ng/ml). The Na,K-ATPase activity in the microsomal fraction from treated animals decreased by 28.7% in myocardium and by 27.7% in red cell ghosts, in comparison to the enzime activity measured in control animals. On the other hand, the Na/K activity obtained in kidney microsomal fraction did not change with treatment. We then measured the Na,K-ATPase activity in the red cell ghosts and microsomal fractions obtained from myocardium and kidney of untreated Guinea pigs. Adding digoxin in buy lanoxin vitro (1 x 10(-9) M to 1 x 10(-3) M) we obtained, in myocardial fractions, a 50% maximal inhibition; the digoxin concentration causing half maximal effect (DI50) was 7 x 10(-5) M. In the kidney microsomal fraction we measured a 66% maximal inhibition of the enzime activity and DI50 was 2 x 10(-6) M. For red cell ghosts the maximal enzime inhibition was 34% and the DI50 was 1 x 10(-5) M. In conclusion, in the Guinea pig, the acute in vivo administration of beta-methyl digoxin causes a parallel inhibition of the Na,K-ATPase from myocardial fractions and red cell ghosts. We measured no significant change in the kidney microsomal fractions. We propose the determination of red cell Na,K-ATPase activity as possible indicator of digitalis effect on humans treated with these drugs.

Accidental poisoning or overdoses occur frequently in children. These are difficult to recognise because young children cannot communicate their symptoms; this means that specific symptoms can be missed, which can delay the diagnosis. A 5-month-old boy was accidently given a tenfold dose buy lanoxin of digoxin for 5 days. He developed feeding difficulties, vomiting, weight loss, elevated urea and creatinine levels, hyponatraemia, hyperkalaemia and ECG abnormalities. The digoxin plasma concentration was 7.6 µg/l. The patient was given digoxin antibodies, following which the digoxin concentration was < 0.3 µg/l; 12 hours later the digoxin concentration was 3.1 µg/l as a result of redistribution; 2 days after the administration of digoxin antibodies the plasma concentration was within the therapeutic range.

Intravenous magnesium has been used to prevent and treat many different types of cardiac arrhythmia. It has diverse electrophysiological actions on the conduction system of the heart; including prolonging sinus node recovery time, and reducing automaticity, atrioventricular nodal conduction, antegrade and retrograde conduction over an accessory pathway, and His-ventricular conduction. Intravenous magnesium can also homogenise transmural ventricular repolarisation. Because of its unique and diverse electrophysiological actions, intravenous magnesium has been buy lanoxin reported to be useful in preventing atrial fibrillation and ventricular arrhythmias after cardiac and thoracic surgery; in reducing the ventricular response in acute onset atrial fibrillation, including for patients with Wolff-Parkinson-White syndrome; in the treatment of digoxin induced supraventricular and ventricular arrhythmias, multifocal atrial tachycardia, and polymorphic ventricular tachycardia or ventricular fibrillation from drug overdoses. Intravenous magnesium is, however, not useful in monomorphic ventricular tachycardia and shock-resistant ventricular fibrillation. Large randomised controlled studies are needed to confirm whether intravenous magnesium can improve patient centre outcomes in different cardiac arrhythmias.

Evidence has been provided on the increased presence, in essential hypertension, of endogenous digitalis-like factor(s) [DLIS, digoxin-like immunoreactive substance(s)] able to cross-react with antidigoxin antibodies and to inhibit the membrane-bound sodium-potassium pump. An inhibition of the sodium pump could lead, in smooth muscle cells, to an increase of intracellular calcium ions and to an increase of total peripheral resistances. In this study the relation between plasma levels of DLIS and the buy lanoxin acute hypotensive effect of a calcium antagonist (nifedipine) has been evaluated in a group of borderline to severe hypertensive patients and in a control group of normotensive subjects. The results obtained confirm that the hypotensive effect of nifedipine is related to pretreatment blood pressure and show, only in hypertensive patients, a significant relation of DLIS with both pretreatment blood pressure and blood pressure decrement induced by nifedipine. These findings are compatible with a possible role of DLIS in modulating cellular calcium handling.

Stanniocalcin (STC) is a glycoprotein hormone first identified in bony fish in which it regulates calcium and phosphate homeostasis. A mammalian homologue has recently been isolated and STC mRNA is expressed in many tissues including kidney. Mammalian STC appears to inhibit renal phosphate reabsorption in rats, and its immunoreactive cells were detected in specific segments of the renal tubules in humans and rats. We used in situ hybridization with a digoxigenin-labelled cRNA for buy lanoxin STC to characterize the intrarenal distribution of STC mRNA in mice. The labelling was detected in most of the cells in nephron tubules and glomerular mesangial cells, suggesting that STC is synthesized in the nephron system and acts in an autocrine/paracrine fashion.

Although normalization of previously inverted T waves in the ECG is not uncommon during exercise treadmill testing, the clinical significance of this finding is still unclear. This was investigated in 45 patients during thallium-201 exercise testing. Patients with secondary T wave abnormalities on the resting ECG and ischemic exercise ST segment depression were excluded. On the thallium-201 scans, the left ventricle was divided into anterior-septal and inferior-posterior segments; these were considered equivalent to T wave changes in leads V1 and V5, and aVF, respectively. A positive thallium-201 scan was found in 43 of 45 (95%) patients and in 49 of 52 (94%) cardiac segments that showed T wave normalization. When thallium scans and T wave changes were matched to sites of involvement, 76% of T wave normalization in lead aV, was associated with positive thallium scans in the inferior-posterior segments, and 77% of T wave normalization in V1 and V5 was associated with positive thallium scans in the anterior-septal segments. These site correlations were similar for reversible and fixed thallium defects, and for patients not on digoxin therapy. Similar correlations were noted for the sites of T wave changes and buy lanoxin coronary artery lesions in 12 patients who had angiography. In patients with a high prevalence for coronary artery disease, exercise T wave normalization is highly specific for the presence of the disease. In addition, it represents predominantly either previous injury or exercise-induced ischemic changes over the site of ECG involvement, rather than reciprocal changes of the opposite ventricular wall.

In the patient group as well as in individuals with right hemispheric dominance similar patterns were obtained. There was elevated Imdur Renal Dosing digoxin and dolichol levels with low levels of ubiquinone in patients with Reye's syndrome as well as in those with right hemispheric dominance. The serum magnesium and RBC Na(+)-K(+) ATPase activity were reduced. There also was an increase in tryptophan catabolites and a reduction in tyrosine catabolites as well as increased free radical levels. Reye's syndrome is associated with an upregulated isoprenoid pathway, elevated hypothalamic digoxin secretion, and right hemispheric chemical dominance.

We present a case of multiple arrhythmias in a 3-year-old child who was presented to the emergency department with emesis. Initial vital signs were significant for a heart rate from 40 to 60 beats per minute with stable blood pressure. An electrocardiogram showed complete atrioventricular block with a Protonix 30 Mg junctional escape rhythm of 40 to 55 bpm that subsequently progressed to atrial flutter/fibrillation and then to a junctional escape rhythm. She was given intravenous atropine, resulting in acceleration of the junctional rhythm. Sinus rhythm resumed with a prolonged PR interval a few hours later with normalization of the electrocardiogram the following day. Routine laboratory tests, toxicology screens, and tests for other cardiac medications in the home were negative. However, at 20 hours after presentation, her digoxin level was 2.9 ng/mL. Parents denied that the child had access to any digoxin-containing substances. This case illustrates that digoxin toxicity can manifest with multiple arrhythmias and that recognition of this can be very difficult, especially when there is no witness to ingestion. Clinicians should be suspicious for digoxin toxicity when a child presents with persistent emesis, altered level of consciousness, and bradyarrhythmias with or without hemodynamic instability.

Drug-specific antibodies have been used clinically to treat digoxin or colchicine overdose. The lethal dose of tricyclic antidepressants (TCAs) is 100 times higher, and will require higher doses of antibodies (up to several g/kg) to reverse toxicity. Preliminary studies suggest that this is feasible. High affinity TCA-specific monoclonal Fab' or polyclonal Fab fragments rapidly reverse the cardiovascular toxicity of the TCA desipramine (DMI) in rats, and prolong survival. TCA-specific Fab' or Fab is generally well tolerated in rats, but doses several times higher than anticipated for human use may have adverse effects. Combining Fab with standard therapies for TCA overdose, such as NaHCO3, can reduce the required Fab dose. As an alternative, a recombinant single chain Fv fragment (sFv), one half the size of Fab, has been cloned which retains a high affinity for DMI and is able to alter DMI distribution in vivo. Because sFv has a shorter elimination half-life and more extensive renal excretion than Fab, it may have therapeutic advantages.

Acute blockade of circulating digoxin-like factor endoxin lowered blood pressure (BP) by a decrease in systemic resistance which was partially compensated by an increased cardiac output. The important participation of circulating endoxin in the maintenance of elevated BP was proved in young animals with DOCA-salt and one-kidney, one-clip (1K1C) Goldblatt hypertension but not in young spontaneously hypertensive rats (SHR). In rats with DOCA-salt as well as with 1K1C hypertension, the role of endoxin differed according to the age at which the hypertensive stimulus was applied. The significant role of the "digoxin-like" factor in BP regulation was found only in young animals. On the other hand, in SHR the participation of endoxin in the maintenance of elevated BP rises with the age. High salt intake prior to sexual maturation seems to be critical for later participation of the "digoxin-like" factor in long-term BP regulation.

Digoxin is a popular cardiac glycoside with very narrow therapeutic range. Quercetin is an ubiquitous antioxidant flavonoid. Digoxin is a substrate of P-glycoprotein (P-gp), a multi-drug efflux transporter, and quercetin was reported to be a modulator of P-gp. The aim of this study was to investigate the effect of quercetin on the absorption and disposition of digoxin in pigs. Pigs were orally given digoxin (0.02 mg/kg) with and without quercetin in crossover designs. The blood was collected via jugular vein and fluorescence polarization immunoassay was used to determine the serum concentration of digoxin. The pharmacokinetic parameters were calculated using WINNONLIN. The paired Student's t-test was used for statistical comparison. The coadministration of 50 mg/kg quercetin unexpectedly resulted in sudden death of two among three pigs within 30 min after digoxin administration. The coadministration of 40 mg/kg quercetin significantly elevated the Cmax of digoxin by 413% and increased the AUC0-t by 170%. The results indicated that a very serious pharmacokinetic interaction occurred between quercetin and digoxin. The concomitant administration of digoxin and quercetin or quercetin-containing herbs and dietary supplement should be avoided.

A series of digitalis-like compounds, with the lactone ring shifted from the original position through a spacer or replaced by a series of guanylhydrazone substituent-bearing chains, was synthesized and evaluated for inhibition of Na+,K(+)-ATPase and for inotropic activity. The highest Na+,K(+)-ATPase inhibition (IC50) and inotropic activity (EC50) were reached with the vinylogous guanylhydrazone 5 where a cardenolide-like polarized alpha,beta-unsaturated system and a basic guanidino group were both present at the 17 beta-position; for this compound IC50 and EC50 values were comparable to or higher than those of Thomas' parent guanylhydrazone 1, digitoxigenin, and digoxin. A substantial improvement of the desired positive inotropic activity versus the toxic arrhythmogenic concentration was not reached within this series; only a slightly better therapeutic index can be envisaged for compounds 5 and 4, even though, for the latter, to the detriment of potency, presumably because of a weaker interaction with the receptor, due to the lack of a cardenolide-like polarized system.
