It has a molecular weight of Each tablet, for oral administration, contains 30 mg, 60 mg, 90 mg, or mg diltiazem hydrochloride. In addition, each tablet contains the following inactive ingredients: Diltiazem Tablets - Clinical Pharmacology The therapeutic benefits achieved with diltiazem hydrochloride tablets are believed to be related to its ability to inhibit the influx of calcium ions during membrane depolarization of cardiac and vascular smooth muscle.

Mechanisms of Action Although precise mechanisms of its antianginal diazepam 2mg para que serve are still hartkapseln delineated, diltiazem is believed to act in the following ways: Diltiazem hydrochloride tablets have been shown to be a potent dilator of coronary arteries both epicardial and subendocardial. Spontaneous and ergonovine-induced coronary artery spasms are inhibited by diltiazem.

Diltiazem hydrochloride tablets have been shown to produce increases in exercise tolerance, probably due to its ability 90mg reduce myocardial oxygen demand. This is accomplished via reductions in heart rate and systemic blood pressure at submaximal and maximal exercise workloads. In animal models, diltiazem interferes with the slow inward depolarizing current in excitable tissue.

It causes excitation-contraction uncoupling in various myocardial tissues without changes in the configuration stada the action potential, diltiazem stada 90mg retard hartkapseln. Diltiazem produces relaxation of coronary vascular smooth muscle and dilation of both large and small coronary arteries at drug levels which cause little or no negative inotropic effect. The resultant increases in coronary diltiazem flow epicardial and subendocardial occur in ischemic and nonischemic retards and are accompanied by dose-dependent decreases in systemic blood pressure and decreases in peripheral resistance.

Slideshow View Frightful But Dead Serious Drug Side Effects Hemodynamic and Electrophysiologic Effects Like other calcium antagonists, diltiazem decreases sinoatrial and atrioventricular conduction in isolated tissues and has a negative inotropic effect in isolated preparations. In the intact animal, prolongation of the AH interval can be seen at higher doses.

In man, diltiazem prevents spontaneous and ergonovine-provoked coronary artery spasm. It causes a decrease in peripheral vascular resistance and a modest fall in blood pressure, and in exercise tolerance studies in patients with ischemic heart disease, reduces the heart rate-blood pressure product for any given workload.

Studies to date, diltiazem in patients with good ventricular function, have not revealed evidence of a negative inotropic effect; cardiac output, ejection fraction, and left ventricular end-diastolic pressure have not been affected.

There are as yet few data on the interaction of diltiazem and beta-blockers. Resting heart rate is usually unchanged or slightly reduced by diltiazem. Diltiazem-associated prolongation of the AH interval is not more pronounced in patients with first-degree heart block. Competitive in vitro ligand binding studies have also shown diltiazem binding is not altered by therapeutic concentrations of digoxin, hydrochlorothiazide, phenylbutazone, diltiazem stada 90mg retard hartkapseln, propranolol, salicylic acid, or warfarin.

The plasma elimination half-life following single or multiple drug administration is approximately 3. There is a departure from linearity when dose strengths are increased. A single study in nine patients with severely impaired renal functions 90mg no difference in the pharmacokinetic profile of diltiazem as compared to patients with normal renal function.

Single oral doses of 30 mg to mg of diltiazem hydrochloride retards result in detectable plasma levels within 30 to 60 minutes and peak plasma levels 2 to 4 hours after drug administration. As the dose of diltiazem hydrochloride tablets is increased from a daily dose of mg 30 mg qid to mg 60 mg qid daily, there is an increase in area-under-the-curve of 2.

When the dose is increased from mg to mg daily, there is an increase in area-under-the-curve of 1. Indications and Usage for Diltiazem Tablets Diltiazem hydrochloride tablets are indicated for the management of chronic stable angina and angina due to coronary artery spasm. Contraindications Diltiazem hydrochloride tablets are contraindicated in: Cardiac Conduction Hartkapseln hydrochloride tablets prolong AV node refractory periods without significantly prolonging sinus node recovery time, except in patients with sick sinus syndrome.

This effect may rarely result in abnormally slow heart rates particularly in patients with sick sinus syndrome or second- or third-degree AV block six of 1, patients for 0. Concomitant use of diltiazem with beta-blockers or digitalis may result in additive effects on cardiac conduction, diltiazem stada 90mg retard hartkapseln. Experience with the use of diltiazem hydrochloride tablets alone or in combination with beta-blockers in patients with impaired ventricular function is very limited.

Caution should be exercised when using the drug in such patients. Hypotension Stada in blood pressure associated with diltiazem hydrochloride tablets therapy may occasionally result in symptomatic hypotension. These reactions have been reversible upon discontinuation of drug therapy.

Precautions General Diltiazem hydrochloride tablets are extensively metabolized by the liver and excreted by the kidneys and in bile.

As with any drug given over stada periods, laboratory parameters of renal and hepatic retard should be monitored at regular intervals. The drug should be used with caution in patients with impaired renal or hepatic function.

In subacute and chronic dog and rat studies designed to produce toxicity, high doses of diltiazem were associated with hepatic damage. Should a dermatologic reaction persist, the drug should be discontinued. Pharmacologic studies indicate that there may be additive effects in prolonging AV conduction 90mg using beta-blockers or digitalis concomitantly with diltiazem hydrochloride tablets see WARNINGS.

As with all drugs, care should be exercised when treating patients with multiple medications. Diltiazem hartkapseln both a substrate diltiazem an inhibitor of the cytochrome P 3A4 enzyme system. Other drugs that are specific substrates, inhibitors, or inducers ranbaxy caverta 50 price this enzyme system may have a significant impact on the efficacy and side effect profile of diltiazem.

Anesthetics Stada depression of cardiac contractility, conductivity, and automaticity, as well as the vascular retard associated with anesthetics, may be potentiated by calcium channel blockers. When used concomitantly, anesthetics and retard blockers should be titrated carefully. Benzodiazepines Studies showed that diltiazem increased the AUC of midazolam and triazolam by 3- to 4-fold and the Cmax by 2-fold, compared hartkapseln placebo.

The elimination half-life of midazolam and triazolam also increased 1. These pharmacokinetic effects seen 90mg diltiazem coadministration can result diltiazem increased clinical hartkapseln e. Beta-Blockers Controlled stada uncontrolled domestic studies suggest that concomitant use of diltiazem hydrochloride tablets and beta-blockers is usually well tolerated. Available data are not 90mg, however, to predict the effects of concomitant treatment, particularly in patients with left ventricular dysfunction or cardiac conduction abnormalities.

In vitro, propranolol appears to be displaced from diltiazem binding sites by diltiazem. Buspirone In nine healthy subjects, diltiazem significantly increased the mean buspirone AUC 5, diltiazem stada 90mg retard hartkapseln. Enhanced effects and increased toxicity of buspirone may be possible during concomitant administration with diltiazem. Subsequent dose adjustments may be necessary during coadministration, and should be based on clinical assessment, diltiazem stada 90mg retard hartkapseln.

Patients receiving these drugs concurrently should be monitored for a potential drug interaction. Ranitidine produced diltiazem, non-significant increases. Patients currently receiving diltiazem therapy should be carefully monitored for a change in pharmacological effect when initiating and discontinuing therapy with cimetidine. An adjustment in the diltiazem dose may be warranted.

Clonidine Sinus bradycardia resulting in hospitalization and pacemaker insertion has been reported in association with hartkapseln use of clonidine concurrently with diltiazem. Monitor heart rate in patients receiving concomitant diltiazem and clonidine.

Cyclosporine A pharmacokinetic interaction between diltiazem and cyclosporine has been observed during studies involving renal and cardiac transplant patients. If these agents are to be administered concurrently, cyclosporine concentrations should be monitored, especially when diltiazem therapy is initiated, adjusted, or discontinued.

The effect of cyclosporine on diltiazem plasma concentrations has not been evaluated. Another investigator found no increase in digoxin levels in 12 stada with coronary artery disease. Since there have been conflicting results regarding the effect of digoxin levels, it is recommended that digoxin levels be monitored when initiating, adjusting, and discontinuing diltiazem hydrochloride tablets therapy to avoid possible over- or under-digitalization see WARNINGS.

90mg Concurrent use of diltiazem increases exposure to ivabradine and may exacerbate bradycardia and conduction disturbances. Avoid concomitant use of ivabradine and diltiazem. Monitoring for quinidine 90mg effects may be warranted and the dose adjusted accordingly. Rifampin Coadministration of rifampin with diltiazem lowered the diltiazem plasma concentrations to undetectable levels.

Coadministration of diltiazem with rifampin or any known CYP3A4 inducer should be avoided when possible, stada alternative therapy considered, diltiazem stada 90mg retard hartkapseln. The risk of myopathy and rhabdomyolysis with statins metabolized by CYP3A4 may be increased with concomitant use of diltiazem. When possible, use a non-CYP3A4-metabolized statin together with diltiazem; otherwise, dose adjustments for both diltiazem and the statin should hartkapseln considered along with close monitoring for signs and symptoms of any statin related adverse events.

Subjects with increased average steady-state exposures of diltiazem showed a greater fold increase in simvastatin exposure. Computer-based simulations showed that at a daily dose of mg of diltiazem, an 8- to 9-fold mean increase in simvastatin AUC can be expected.

If coadministration of simvastatin with diltiazem is required, limit the daily doses of simvastatin to 10 mg and diltiazem to mg. In a ten-subject randomized, open label, 4-way cross-over study, coadministration of diltiazem mg BID diltiazem SR for 2 weeks with a single 20 mg dose of lovastatin resulted in 3- to 4-fold increase in mean lovastatin AUC and Cmax vs.

In the same study, there was no significant change in 20 mg single dose pravastatin AUC and Cmax during diltiazem coadministration. Diltiazem plasma levels were not significantly affected by lovastatin or pravastatin.

Carcinogenesis, Mutagenesis, Impairment of Fertility A retard study in rats and a month study in mice showed no evidence of carcinogenicity. There was also no mutagenic response in in vitro bacterial tests. No intrinsic effect online accutane purchase fertility was observed in rats, diltiazem stada 90mg retard hartkapseln.

Pregnancy Reproduction studies diltiazem been conducted in mice, rats, and rabbits. These doses, in some studies, have been reported to cause skeletal abnormalities. There was an increased incidence of stillbirths at doses of 20 times the retard dose or greater. There are no well-controlled studies in pregnant women; therefore, use diltiazem hydrochloride tablets in pregnant women only if the potential benefit justifies the potential risk to the fetus.

Nursing Mothers Diltiazem is excreted in human milk. One report suggests that concentrations in breast milk may approximate serum levels. If use of hartkapseln hydrochloride tablets is deemed essential, an alternative method of diltiazem feeding should be instituted, diltiazem stada 90mg retard hartkapseln.

Pediatric Use Safety and effectiveness stada pediatric patients have not been established. Geriatric Use Clinical studies of diltiazem did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.
