Abbreviated New Drug Application
DILTIAZEM HYDROCHLORIDE- DILTIAZEM HYDROCHLORIDE TABLET, FILM COATED PD-RX PHARMACEUTICALS, INC. ---------- DESCRIPTION Diltiazem hydrochloride is a calcium ion cellular influx inhibitor (slow channel blocker or calcium antagonist). Chemically, diltiazem hydrochloride 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: Diltiazem hydrochloride, USP is a white to off-white crystalline powder with a bitter taste. It is soluble in water, methanol, and chloroform. It has a molecular weight of 450.99. Each tablet, for oral administration, contains 30 mg, 60 mg, 90 mg, or 120 mg diltiazem hydrochloride. In addition, each tablet contains the following inactive ingredients: ethylcellulose, hypromellose, lactose monohydrate, magnesium stearate, maltodextrin, polyethylene glycol, and sodium lauryl sulfate. For oral administration. 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 actions are still being delineated, diltiazem is believed to act in the following ways: ANGINA DUE TO CORONARY ARTERY SPASM: 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. EXERTIONAL ANGINA: Diltiazem hydrochloride tablets have been shown to produce increases in exercise tolerance, probably due to its ability to 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 i Lue koko asiakirja
