Trandolapril Drug Profile

What is Trandolapril?

Trandolapril is a prescription medication belonging to a class of drugs called ACE (angiotensin-converting enzyme) inhibitors. It is primarily used to treat high blood pressure and heart failure by helping blood vessels relax and widen. This medication is taken orally and works by blocking an enzyme that causes blood vessels to narrow.

Uses

Trandolapril is approved for several cardiovascular conditions:

• Hypertension (High Blood Pressure): Used as a first-line treatment to lower blood pressure and reduce the risk of stroke, heart attack, and kidney problems
• Heart Failure: Helps improve symptoms and survival in patients with reduced heart function by decreasing the workload on the heart
• Post-Heart Attack Treatment: Prescribed to patients who have survived a heart attack to prevent further cardiovascular events and improve long-term outcomes
• Diabetic Kidney Disease: May be used to slow the progression of kidney damage in diabetic patients with high blood pressure
• Cardiovascular Risk Reduction: Prescribed for patients at high risk of heart disease to prevent future cardiovascular events

How it works

Trandolapril works by blocking the angiotensin-converting enzyme (ACE), which normally converts angiotensin I to angiotensin II, a powerful substance that causes blood vessels to constrict. By inhibiting this enzyme, trandolapril allows blood vessels to remain relaxed and dilated, reducing blood pressure and decreasing the heart’s workload. Additionally, it reduces the breakdown of bradykinin, a substance that also helps keep blood vessels open.

Side effects

Common side effects include:

Submit Your Paper

• Dry, persistent cough
• Dizziness or lightheadedness
• Fatigue or weakness
• Headache
• Nausea or stomach upset
• Low blood pressure
• Elevated potassium levels
• Skin rash

Serious side effects requiring immediate medical attention:

• Angioedema (swelling of face, lips, tongue, or throat)
• Severe kidney problems or kidney failure
• Dangerously high potassium levels
• Severe allergic reactions
• Liver dysfunction

Warnings and precautions

• Pregnancy: Trandolapril is contraindicated during pregnancy, especially in the second and third trimesters, as it can cause serious harm or death to the developing fetus
• Kidney disease: Patients with severe kidney disease or those on dialysis should use this medication with extreme caution, as it can worsen kidney function
• Angioedema history: Individuals with a previous history of angioedema should not take trandolapril due to increased risk of life-threatening swelling
• Dehydration: Patients who are dehydrated, have low sodium levels, or are taking diuretics may experience dangerous drops in blood pressure
• Liver impairment: Those with liver disease may need dose adjustments, as the medication is processed by the liver

Interactions

• Potassium supplements and salt substitutes: Can cause dangerously high potassium levels when combined with trandolapril
• Diuretics: May increase the risk of low blood pressure, especially when starting treatment
• NSAIDs (ibuprofen, naproxen): Can reduce the effectiveness of trandolapril and increase kidney damage risk
• Lithium: Trandolapril may increase lithium levels in the blood, leading to toxicity
• Diabetes medications: ACE inhibitors may enhance the blood sugar-lowering effects of diabetes drugs
• Other blood pressure medications: Combined use may cause excessive blood pressure reduction
• Aliskiren: Should be avoided in patients with diabetes or kidney disease due to increased risk of complications
• Gold injections: May cause severe reactions when used with ACE inhibitors

Dosage

The typical starting dose for adults with hypertension is 1-2 mg once daily, which may be increased gradually to a maintenance dose of 2-4 mg daily based on blood pressure response. For heart failure, the starting dose is usually 1 mg daily, potentially increased to 4 mg daily as tolerated. Patients with kidney or liver impairment may require lower doses. The maximum recommended dose is generally 8 mg daily. Dosage adjustments should always be made under medical supervision, and patients should take the medication at the same time each day, with or without food.
