The content of this page:
How does this medication work? What will it do for me?
This combination product contains two active ingredients: trandolapril and verapamil. Trandolapril belongs to the class of medications called ACE inhibitors. Trandolapril works by relaxing blood vessels and making it easier for the heart to pump blood. Verapamil belongs to the class of medications called calcium channel blockers. Verapamil works by relaxing blood vessels and normalizing heart rhythms.
This combination medication is used to treat mild-to-moderate high blood pressure (hypertension). This combination medication is prescribed when your doctor feels it is appropriate for you to be taking both medications and you have taken trandolapril and verapamil as separate medications without any problems. Trandolapril - verapamil combination should not be used for initial treatment. The blood-pressure-lowering effects are usually seen within a week of starting this medication but it may take longer to see the full effects of the medication.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.
Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.
