In short
This article summarizes several clinical trials investigating the use of Trandolapril, an angiotensin-converting enzyme (ACE) inhibitor, in treating hypertension and other medical conditions. These studies examine Trandolapril's effectiveness, safety profile, and potential benefits compared to other treatments. The trials cover various aspects, including bioequivalence studies, combination therapies, and its effects on specific patient populations such as those with diabetes or aortic stenosis.

What is Trandolapril?
Trandolapril is a medication that belongs to a class of drugs called Angiotensin-Converting Enzyme (ACE) inhibitors. It is known by various brand names, including Mavik and Gopten. Trandolapril is also available in combination with other medications, such as verapamil, under brand names like Tarka, VeraTran, or ABT-TARKA.
Uses of Trandolapril
Trandolapril is primarily used to treat the following conditions:
- Hypertension (High Blood Pressure): Trandolapril is effective in lowering blood pressure in patients with hypertension.
- Coronary Artery Disease (CAD): It is used in the management of patients with CAD, often in combination with other medications.
- Diabetic Nephropathy: Trandolapril may help prevent or slow the progression of kidney disease in patients with type 2 diabetes.
How Trandolapril Works
Trandolapril works by inhibiting the angiotensin-converting enzyme (ACE) in the body. This enzyme is responsible for producing a substance called angiotensin II, which causes blood vessels to narrow. By blocking this enzyme, trandolapril helps blood vessels relax and widen, which lowers blood pressure and improves blood flow.
Forms and Dosages
Trandolapril is available in tablet form and comes in various strengths, including:
- 0.5 mg
- 1 mg
- 2 mg
- 4 mg
The dosage may vary depending on the patient's condition and response to treatment. In some studies, dosages were escalated from 0.5 mg to 4 mg daily over several weeks.
Clinical Studies
Several clinical studies have been conducted to evaluate the efficacy and safety of trandolapril:
- TRAIL Study: This study examined the effects of escalating doses of trandolapril on lowering blood pressure in patients with Stage 1-2 hypertension.
- BENEDICT Study: This study investigated the use of trandolapril, alone or in combination with verapamil, in preventing kidney disease in patients with type 2 diabetes.
- INVEST Study: This large international study compared treatment strategies involving trandolapril and other medications in patients with hypertension and coronary artery disease.
- MEAD Study: This study looked at the metabolic effects of trandolapril in people with metabolic syndrome, a condition that increases the risk of diabetes and heart disease.
Side Effects and Safety
While trandolapril is generally well-tolerated, it can cause side effects in some patients. Common side effects may include:
- Dizziness
- Headache
- Cough
- Fatigue
In clinical trials, the safety of trandolapril was closely monitored. For example, in the MEAD study, researchers specifically looked at how trandolapril affected blood sugar levels in people at risk for diabetes.
Special Considerations
There are some special considerations to keep in mind when using trandolapril:
- Pregnancy: Trandolapril can harm an unborn baby and should not be used during pregnancy.
- Kidney Function: Patients with kidney problems may need dose adjustments.
- Aortic Stenosis: While traditionally contraindicated, some studies have investigated the use of ACE inhibitors like trandolapril in patients with aortic stenosis (narrowing of the aortic valve).
- Combination Therapy: Trandolapril is often used in combination with other medications, such as verapamil or hydrochlorothiazide, for better blood pressure control.
