About Tarka

What Tarka is used for

TARKA is used to treat hypertension (high blood pressure).

Both trandolapril and verapamil should normally be used in those patients in whom treatment with a diuretic or a beta-blocker were found to be ineffective or were associated with unacceptable adverse effects. They can be tried as initial agents in those patients in whom diuretics and/or beta-blockers are contraindicated or in patients with medical conditions in which these drugs frequently cause serious adverse effects.

What Tarka does

TARKA contains two different types of medicines: a calcium channel blocker and an Angiotensin Converting Enzyme (ACE) inhibitor.

Calcium channel blockers change the amount of calcium getting into the muscle cells of your heart and blood vessels. This can change the strength and speed at which your heart beats. It also opens up the blood vessels so that blood can be pumped around your body more easily. This helps to lower your blood pressure.

ACE inhibitors also work by widening blood vessels, so helping to lower your blood pressure.

When Tarka should not be used

TARKA should not be used if:

  • you are allergic to any component of TARKA, including active ingredients and non-active ingredients

  • you are pregnant or breast feeding or

  • you have certain serious heart conditions.

Ask your doctor for advice.

Proper Use of Tarka

Usual dose

Dosage must be individualized. The fixed combination is not for initial therapy. The dose of TARKA should be determined by titration of the individual components. TARKA should be taken once-a-day at the same time every day.

The usual adult dose for verapamil monotherapy is 180 to 240 mg/day.

The usual maintenance dose for trandolapril monotherapy is 1 to 2 mg once daily, as the recommended initial dose is 1 mg once daily.

Take TARKA with food to help it work better. TARKA sustained-release tablets should not be divided, crushed or chewed.


If you or someone you know accidentally takes more than stated dose, contact your doctor immediately or go to the nearest hospital with the tablets. Tell your doctor or hospital how much was taken. Treat even small overdoses seriously.

Missed dose

If you forget to take one tablet, take another as soon as you remember, unless it is almost time for your next dose. If it is, do not take the missed tablet at all.

Never double-up on a missed dose.
