Diltiazem Hydrochloride is a calcium channel blocker with vasodilating activity. Anti-anginal; anti-hypertensive; anti-arrhythmic (class IV). | [Uses]
Peripheral Vasodilator | [Definition]
ChEBI: A hydrochloride salt resulting from the reaction of equimolar amounts of diltiazem and hydrogen chloride. A calcium-channel blocker and vasodilator, it is used in the management of angina pectoris and hypertension. | [Manufacturing Process]
β-Diethylaminoethyl chloride is condensed with 2-(4-methoxyphenyl)-3-
hydroxy-2,3-dihydro-1,5-benzothiazepin-4(5H)-one in a first step. Then a
mixture of 1.5 grams of 2-(4-methoxyphenyl)-3-hydroxy-5-(βdimethylaminoethyl)-2,3-dihydro-1,5-benzothiazepin-4(5H)-one and 20 ml of
acetic anhydride was heated on a water bath for 5 hours. The reaction
mixture was evaporated under reduced pressure to remove acetic anhydride
and the concentrated product was poured into ice water. The resulting mixture
was made alkaline with sodium bicarbonate and extracted with chloroform.
The chloroform layer was dried and evaporated to remove the solvent. The
residue was dissolved in acetone, and an ethanol solution containing hydrogen
chloride was added thereto producing 1.53 grams of 2-(4-methoxyphenyl)3-
acetoxy-5-(β-dimethylaminoethyl)-2,3-dihydro-1,5-benzothiazepin-4(5H)-one
hydrochloride having a melting point from 187° to 188°C.
The starting material is made by reacting 4-methoxybenzaldehyde with ethyl
chloroacetate; that product with sodium ethoxide; and that product with 2-
aminothiophenol. | [Brand name]

Coronary vasodilator | [General Description]
Diltiazem hydrochloride,(+)-cis-3-(acetoxy)-5-[2(dimethylamino)ethyl]-2,3-dihydro-2-(4-methoxyphenyl)1,5-benzothiazepin-4(5H)one hydrochloride(Cardizem), was developed and introduced inJapan as a cardiovascular agent to treat angina pectoris. Itwas observed to dilate peripheral arteries and arterioles. Thedrug increases myocardial oxygen supply by relieving coronaryartery spasm and reduces myocardial oxygen demandby decreasing heart rate and reducing overload. Diltiazemhydrochloride is used in patients with variant angina. Thedrug has electrophysiological properties similar to those ofverapamil and is used in clinically similar treatment conditionsas an antiarrhythmic agent, but it is less potent.
The drug is absorbed rapidly and almost completely fromthe digestive tract. It reaches peak plasma levels within 1hour after administration in gelatin capsules. Oral formulationson the market are sustained-release preparations providingpeak plasma levels 3 to 4 hours after administration. | [Biological Activity]
Antihypertensive and cardioprotective agent; an inhibitor of L-type Ca 2+ channels. | [Biochem/physiol Actions]
Product does not compete with ATP. | [Clinical Use]
Calcium-channel blocker:
Prophylaxis and treatment of angina
Hypertension | [Metabolism]
Diltiazem is almost completely absorbed from the
gastrointestinal tract after oral doses, but undergoes
extensive first-pass hepatic metabolism resulting in a
bioavailability of about 40%. It is extensively metabolised
in the liver, mainly by the cytochrome P450 isoenzyme
CYP3A4; one of the metabolites, desacetyldiltiazem,
has been reported to have 25-50% of the activity of the
parent compound
About 2-4% of a dose is excreted in urine as unchanged
diltiazem with the remainder excreted as metabolites in
bile and urine. | [storage]
Store at RT | [Mode of action]
Diltiazem Hydrochloride is a benzothiazepine calcium channel blocking agent. Diltiazem hydrochloride inhibits the transmembrane influx of extracellular calcium ions into select myocardial and vascular smooth muscle cells, causing dilatation of coronary and systemic arteries and decreasing myocardial contractility. Because of its vasodilatory activity, this agent has been shown to improve the microcirculation in some tumors, thereby potentially improving the delivery of antineoplastic agents to tumor cells. | [References]
