PRESCRIPTION DRUG
Diltiazem hydrochloride tablets are indicated for the management of chronic stable angina and angina due to coronary artery spasm. Diltiazem is contraindicated in: - Patients with sick sinus syndrome except in the presence of a functioning ventricular pacemaker - Patients with second- or third-degree AV block except in the presence of a functioning ventricular pacemaker - Patients with hypotension (less than 90 mm Hg systolic) - Patients who have demonstrated hypersensitivity to the drug - Patients with acute myocardial infarction and pulmonary congestion documented by x-ray on admission

Abbreviated New Drug Application
DILTIAZEM HYDROCHLORIDE- DILTIAZEM HYDROCHLORIDE TABLET, FILM COATED BRYANT RANCH PREPACK ---------- DILTIAZEM HYDROCHLORIDE TABLETS, USP RX ONLY DESCRIPTION Diltiazem hydrochloride tablets, USP are a calcium ion cellular influx inhibitor (slow channel blocker or calcium antagonist). Chemically, diltiazem hydrochloride, USP is 1,5- Benzothiazepin-4(5_H_)-one,3-(acetyloxy)-5-[2-(dimethylamino)ethyl]-2,3-dihydro-2-(4- methoxyphenyl)-, monohydrochloride,(+)-cis-. The structural formula is: C H N O S•HCl M.W. 450.98 Diltiazem hydrochloride, USP is a white to off-white crystalline powder with a bitter taste. It is soluble in water, methanol, and chloroform. Each tablet for oral administration contains 30 mg, 60 mg, 90 mg, or 120 mg of diltiazem hydrochloride, USP. Each tablet also contains the following inactive ingredients: hypromellose, lactose monohydrate, magnesium stearate, polyethylene glycol, polysorbate 80, povidone, titanium dioxide and FD&C yellow No. 6 aluminum lake. CLINICAL PHARMACOLOGY The therapeutic benefits achieved with diltiazem 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 actions are still being delineated, diltiazem is believed to act in the following ways: ANGINA DUE TO CORONARY ARTERY SPASM: Diltiazem has 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. EXERTIONAL ANGINA: Diltiazem has been shown to produce increases in exercise tolerance, probably due to its ability to reduce myocardial oxygen demand. This is 22 26 2 4 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 myocardi Přečtěte si celý dokument
