1. What DILZEM XL is and what it is used for

DILZEM XL contains the active ingredient, diltiazem hydrochloride.

Diltiazem hydrochloride belongs to a group of medicines called calcium channel blockers (which interfere with the movement of calcium in heart muscle cells). These medicines work to lower blood pressure and ease anginal chest pain by preventing the narrowing of blood vessels.

DILZEM XL is designed to release the active ingredient, diltiazem hydrochloride, in a controlled manner throughout the whole day so that blood pressure and angina are treated for a full 24 hour period.

DILZEM XL is used to treat and control mild to moderately high blood pressure and to prevent and treat chest pain (angina pectoris) due to the narrowing of blood vessels in the heart, which is brought on by exercise.
