Cardizem, Cartia, Diltiazem, Teczem, Tiamate, Tiazac (diltiazem) is a small molecule pharmaceutical. Diltiazem was first approved as Cardizem on 1982-11-05. It is used to treat atrial fibrillation, atrial flutter, hypertension, myocardial infarction, and supraventricular tachycardia amongst others in the USA. The pharmaceutical is active against voltage-dependent L-type calcium channel subunit alpha-1S. In addition, it is known to target potassium voltage-gated channel subfamily A member 1, cyclic nucleotide-gated channel alpha-3, voltage-dependent L-type calcium channel subunit alpha-1F, voltage-dependent L-type calcium channel subunit alpha-1D, potassium voltage-gated channel subfamily A member 5, cyclic nucleotide-gated channel alpha-1, cyclic nucleotide-gated channel beta-3, cyclic nucleotide-gated channel alpha-2, potassium voltage-gated channel subfamily A member 2, voltage-gated potassium channel KCNC1, voltage-dependent L-type calcium channel subunit alpha-1C, and potassium voltage-gated channel subfamily A member 7.

Drug
General
| Drug common name | Diltiazem |
| INN | diltiazem |
| Description | Diltiazem is a 5-[2-(dimethylamino)ethyl]-2-(4-methoxyphenyl)-4-oxo-2,3,4,5-tetrahydro-1,5-benzothiazepin-3-yl acetate in which both stereocentres have S configuration. A calcium-channel blocker and vasodilator, it is used as the hydrochloride in the management of angina pectoris and hypertension. It has a role as a calcium channel blocker, a vasodilator agent and an antihypertensive agent. It is a conjugate base of a diltiazem(1+). It is an enantiomer of an ent-diltiazem. |
