Classification: Calcium channel blocking agent (antianginal, antihypertensive)

Action/Kinetics: Decreases SA and AV conduction and prolongs AV node effective and functional refractory periods. Also decreases myocardial contractility and peripheral vascular resistance. Tablets: Onset, 30-60 min; time to peak plasma levels: 2-3 hr; t 1/2, first phase: 20-30 min; second phase: about 3-4.5 hr (5-8 hr with high and repetitive doses); duration: 4-8 hr. Extended-Release Capsules: Onset, 2-3 hr; time to peak plasma levels: 6-11 hr; t 1/2: 5-7 hr; duration: 12 hr. Therapeutic serum levels: 0.05-0.2 mcg/mL. Metabolized to desacetyldiltiazem, which manifests 25%-50% of the activity of diltiazem. Excreted through both the bile and urine.

Uses: Tablets: Vasospastic angina (Prinzmetal's variant). Chronic stable angina (classic effort-associated angina), especially in clients who cannot use beta-adrenergic blockers or nitrates or who remain symptomatic after clinical doses of these agents. Sustained-Release Capsules: Essential hypertension, angina. Parenteral: Atrial fibrillation or flutter. Paroxysmal SVT. Cardizem Lyo-Ject is used on an emergency basis for atrial fibrillation or atrial flutter. Cardizem Monovial is used to maintain control of HR for up to 24 hr in atrial fibrillation or flutter. Investigational: Prophylaxis of reinfarction of nonQ wave MI; tardive dyskinesia, Raynaud's syndrome.

Contraindications: Hypotension. Second- or third-degree AV block and sick sinus syndrome except in presence of a functioning ventricular pacemaker. Acute MI, pulmonary congestion. Lactation.

Special Concerns: Safety and effectiveness in children have not been determined. The half-life may be increased in geriatric clients. Use with caution in hepatic disease and in CHF. Abrupt withdrawal may cause an increase in the frequency and duration of chest pain. Use with beta blockers or digitalis is usually well tolerated, although the effects of coadministration cannot be predicted (especially in clients with left ventricular dysfunction or cardiac conduction abnormalities).

Side Effects: CV: AV block, bradycardia, CHF, hypotension, syncope, palpitations, peripheral edema, arrhythmias angina, tachycardia, abnormal ECG, ventricular extrasystoles. GI: N&V, diarrhea, constipation, anorexia, abdominal discomfort, cramps, dry mouth, dysgeusia.

Laboratory Test Alterations: Alkaline phosphatase, CPK, LDH, AST, ALT.

Additional Drug Interactions: Anesthetics / Risk of depression of cardiac contractility, conductivity, and automaticity as well as vascular dilation Carbamazepine / Diltiazem effect R/T liver breakdown Cimetidine / Diltiazem bioavailability Cyclosporine / Cyclosporine effect possible renal toxicity Digoxin / Possible serum digoxin levels Lithium / Risk of neurotoxicity Ranitidine / Diltiazem bioavailability Theophyllines / Risk of pharmacologic and toxicologic theophylline effects
