Diltiazem is in a class of drugs called calcium channel blockers. Diltiazem relaxes (widens) your
blood vessels (veins and arteries), which makes it easier for your heart to pump and reduces its
workload.
Enalapril is in a class of drugs called angiotensin-converting-enzyme inhibitors (ACE inhibitors).
Enalapril prevents the constriction (narrowing) of blood vessels (veins and arteries).
The combination, diltiazem and enalapril, is used to lower blood pressure and to prevent and
treat heart failure.
Diltiazem and enalapril may also be used for purposes other than those listed in this medication
guide.
