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. Overdose symptoms may include slow heartbeat, weakness, chest pain, shortness of breath, or fainting.

There are no well-controlled studies in pregnant women; therefore, use Cardizem in pregnant women only if the potential benefit justifies the potential risk to the fetus. Höglund P, Nilsson LG. Physiological disposition of intravenously administered 14C-labeled diltiazem in healthy volunteers. Ther Drug Monit. Patients whose BP is adequately controlled with diltiazem therapy as tablets or other extended-release capsules alone or in combination with another antihypertensive agent may be safely switched to Cardizem CD or Cartia XT extended-release capsules or Cardizem LA extended-release tablets at the nearest equivalent daily dosage. 187 323 325 Subsequent titration of dosage is based on the clinical response of the patient.
Sick sinus syndrome unless a functioning ventricular pacemaker is in place. Cyclosporine: A pharmacokinetic interaction between diltiazem and cyclosporine has been observed during studies involving renal and cardiac transplant patients. In renal and cardiac transplant recipients, a reduction of cyclosporine trough dose ranging from 15% to 48% was necessary to maintain concentrations similar to those seen prior to the addition of diltiazem. 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. Gershanik J, Boecler B, Ensley H et al. The gasping syndrome and benzyl alcohol poisoning. N Engl J Med.

WebMD does not endorse any specific product, service or treatment. 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, primarily 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. emot.info aprovel

Cimetidine: A study in six healthy volunteers has shown a significant increase in peak diltiazem plasma levels 58% and area-under-the-curve 53% after a 1-week course of cimetidine at 1200 mg per day and a single dose of diltiazem 60 mg. Ranitidine produced smaller, nonsignificant increases. The effect may be mediated by cimetidine's known inhibition of hepatic cytochrome P450, the enzyme system responsible for the first-pass metabolism of diltiazem. 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. Diltiazem is well absorbed from the gastrointestinal tract and is subject to an extensive first-pass effect, giving an absolute bioavailability compared to intravenous dosing of about 40%. Cardizem undergoes extensive metabolism in which 2% to 4% of the unchanged drug appears in the urine. In vitro binding studies show Cardizem is 70% to 80% bound to plasma proteins. Competitive in vitro ligand binding studies have also shown Cardizem binding is not altered by therapeutic concentrations of digoxin, hydrochlorothiazide, phenylbutazone, propranolol, salicylic acid, or warfarin.
