Tiazac

Generic name: Diltiazem
Dosage form: extended-release capsules (120 mg; 180 mg; 240 mg; 300 mg; 360 mg; 420 mg)

Usage of Tiazac

Tiazac extended-release capsules are used in adults alone or in combination with other medicines to treat hypertension (high blood pressure) or symptoms of chronic stable angina. (chest pain). Lowering blood pressure may lower your risk of a stroke or heart attack.

Tiazac belongs to a class of medications called calcium-channel blockers. It works by relaxing the blood vessels so the heart does not have to pump as hard.

Tiazac also increases the supply of blood and oxygen to the heart.
