This medication is used to treat high blood pressure (hypertension). Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. This product contains 2 medications, trandolapril and verapamil. Trandolapril is an ACE inhibitor, and verapamil is a calcium channel blocker. They both work differently to relax the blood vessels so that blood can flow more easily. Verapamil may also decrease the heart rate. They are used together when one medication is not controlling your blood pressure.
Take this medication by mouth with food, usually once daily or as directed by your doctor. Do not crush or chew extended-release tablets. Doing so can release all of the drug at once, increasing the risk of side effects. Also, do not split the tablets unless they have a score line and your doctor or pharmacist tells you to do so. Swallow the whole or split tablet without crushing or chewing.
The dosage is based on your medical condition and response to treatment.
Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day. It is important to continue taking this medication even if you feel well. Most people with high blood pressure do not feel sick. It may take up to several weeks before you get the full benefit of this drug.

Tell your doctor if your condition does not improve or if it worsens (for example, your routine blood pressure readings remain high or increase).
