What is this medication?
Cardizem CD is described in FDA/DailyMed prescribing information. No separate FDA Medication Guide was found for this label. This summary is based on FDA/DailyMed prescribing information.
What is this medication used for?
CARDIZEM CD is indicated for the treatment of hypertension. It may be used alone or in combination with other antihypertensive medications. CARDIZEM CD is indicated for the management of chronic stable angina and angina due to coronary artery spasm.
What should I know before taking it?
CARDIZEM CD is contraindicated in (1) patients with sick sinus syndrome except in the presence of a functioning ventricular pacemaker, (2) patients with second- or third-degree AV block except in the presence of a functioning ventricular pacemaker, (3) patients with hypotension (less than 90 mm Hg systolic), (4) patients who have demonstrated hypersensitivity to the drug, and (5) patients with acute myocardial infarction and pulmonary congestion documented by x-ray on admission.
What important warnings are listed?
Cardiac Conduction: Diltiazem hydrochloride prolongs 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 (13 of 3290 patients or 0.40%). Concomitant use of diltiazem with beta-blockers or digitalis may result in additive effects on cardiac conduction. A patient with Prinzmetal’s angina developed periods of asystole (2 to 5 seconds) after a single dose of 60 mg of diltiazem (see ADVERSE REACTIONS ). Congestive Heart Failure: Although diltiazem has a negative inotropic.
How is this medication usually taken?
Patients controlled on diltiazem alone or in combination with other medications may be switched to CARDIZEM CD capsules at the nearest equivalent total daily dose. Higher doses of CARDIZEM CD may be needed in some patients. Monitor patients closely. Subsequent titration to higher or lower doses may be necessary. There is limited general clinical experience with doses above 360 mg, but doses to 540 mg have been studied in clinical trials. The incidence of side effects increases as the dose increases with first-degree AV block, dizziness, and sinus bradycardia bearing the strongest relationship to dose. Hypertension: Adjust dosage to individual patient needs. When used as monotherapy,.
What side effects are listed?
Serious adverse reactions have been rare in studies carried out to date, but it should be recognized that patients with impaired ventricular function and cardiac conduction abnormalities have usually been excluded from these studies. The following table presents the most common adverse reactions reported in placebo-controlled angina and hypertension trials in patients receiving CARDIZEM CD up to 360 mg with rates in placebo patients shown for comparison. CARDIZEM CD Capsule Placebo-Controlled Angina and Hypertension Trials Combined Adverse Reactions CARDIZEM CD (n=607) Placebo (n=301) Headache 5.4% 5.0% Dizziness 3.0% 3.0% Bradycardia 3.3% 1.3% AV Block First Degree 3.3% 0.0% Edema 2.6%.
What interactions are listed?
Because of the potential for additive effects, slow titration is warranted in patients receiving diltiazem hydrochloride concomitantly with other agents known to affect cardiac contractility and/or conduction (see WARNINGS ). Pharmacologic studies indicate that there may be additive effects in prolonging AV conduction when using beta-blockers or digitalis concomitantly with CARDIZEM CD (see WARNINGS ). Diltiazem is both a substrate and an inhibitor of the Pg-p and cytochrome P450 3A4 enzyme system which may affect exposure to diltiazem and concomitant drugs metabolized by those pathways. Patients with renal and/or hepatic impairment may be particularly at risk of exposure changes.
