Product Description
Diltiazem is a nondihydropyridines calcium channel blocker used in the treatment of hypertension,angina pectoris, and some types of arrhythmia. It relaxes the smooth muscles in the walls of arteries, which opens (dilates) the arteries, allows blood to flow more easily, and lowers blood pressure. Additionally, it lowers blood pressure by acting on the heart itself to reduce the rate, strength, and conduction speed of each beat.
It is also used off-label as an effective preventive medication for migraine. It is a class 3 antianginal drug, and a class IV antiarrhythmic.
Diltiazem is a potent vasodilator, increasing blood flow and variably decreasing the heart rate via strong depression of A-V node conduction. Its pharmacological activity is somewhat similar to verapamil, another nondihydropyridine (non-DHP) calcium channel blocker.Chemically, it is based upon a 1,4-thiazepine ring making it a benzothiazepine-type calcium channel blocker.
