Lotensin Patient Tips
Medically reviewed on Oct 29, 2017 by C. Fookes, BPharm.
How it works
- Lotensin is a brand (trade) name for benazepril.
- Benazepril inhibits an enzyme called angiotensin-converting enzyme. This enzyme is involved in the production of angiotensin II, a powerful vasoconstrictor (narrows arteries), which also stimulates the release of the hormone aldosterone from the adrenal glands (aldosterone increases blood pressure). By inhibiting this enzyme, benazepril opens up the arteries (vasodilates) and lowers blood pressure.
- Lotensin (benazepril) belongs to a group of medicines known as angiotensin-converting enzyme (ACE) inhibitors.
- Lotensin is used in the treatment of high blood pressure (hypertension), to lower blood pressure. This reduces the risk of fatal and nonfatal cardiac events, including strokes and heart attacks.
- Effective alone or in combination with other treatments for high blood pressure.
- Lotensin is available as a generic under the name benazepril.
If you are between the ages of 18 and 60, take no other medication or have no other medical conditions, side effects you are more likely to experience include:
- A headache and cough are the most common side effects. The cough usually resolves on discontinuation of therapy and is a side effect common to all ACE inhibitors.
- Dizziness, tiredness and postural hypotension (rapid lowering of blood pressure when going from a sitting or lying down position to standing) are also common.
- Occasionally lowering of blood pressure may be excessive. The risk is higher in those on diuretic therapy or who are sodium depleted or dehydrated.
- Rarely may cause angioedema of the face, lips, tongue, throat, and extremities. May occur at any time during treatment. Immediate discontinuation is warranted if angioedema is affecting breathing.
- Also rare is the development of blood disorders and kidney and liver failure.
- May increase blood potassium levels, the risk is higher in people with diabetes, poor kidney function, and in people using potassium-sparing diuretics or taking potassium supplements.
- A ready-made suspension is not available; however, one can be prepared although this is light-sensitive and must be kept in a refrigerator.
- May have less of a blood pressure-lowering effect in patients of African-American descent compared to those without this ethnicity. Also, the incidence of angioedema (skin reaction associated with head and neck swelling) is higher in African-American patients.
- May not be suitable for some people and can interact with a number of other medications (including NSAIDs, lithium) - consult your prescribing doctor before taking any other medications including those brought over the counter. A dosage reduction may be needed in people with kidney disease.
Notes: In general, seniors or children, people with certain medical conditions (such as liver or kidney problems, heart disease, diabetes, seizures) or people who take other medications are more at risk of developing a wider range of side effects.

- May be taken with or without food.
- Usually administered once daily; however, can be administered twice daily if Lotensin's blood pressure lowering capabilities start to wear off too early.
- Treatments that lower blood pressure, such as Lotensin, should always be part of a comprehensive cardiovascular risk reduction plan that also targets, if appropriate, cholesterol lowering, diabetes risk reduction, exercise, weight loss, and smoking cessation.
- Report a sore throat or any signs or symptoms of angioedema (swelling of the face or throat, difficulty breathing) immediately to your doctor.
- Your doctor may require you to undergo regular monitoring (such as kidney and liver tests) while taking Lotensin.
- May cause a fall in blood pressure that may be noticed as light-headedness; this usually goes away after a few days of therapy. However, if it persists, call your doctor and ask for advice; symptoms usually resolve with continued therapy. Ensure you do not become dehydrated.
- Do not use salt substitutes containing potassium without first consulting your doctor.
- Report any signs of a fever or a sore throat to your doctor who may carry out further tests to ensure it is not neutropenia (a decrease in white blood cells).
- Ensure you use adequate contraception or are abstaining from sex to avoid pregnancy while taking Lotensin. If you inadvertently become pregnant while taking Lotensin, contact your healthcare provider immediately.
Response and Effectiveness
- Peak concentrations of Lotensin are reached within half an hour to one hour of oral administration. Lotensin (benazepril) is metabolized to an active metabolite, benazeprilat, which also lowers blood pressure.
- Blood pressure lowering effects are seen within an hour of oral administration with peak effects achieved between two and four hours after dosing. Blood pressure lowering effects are maintained for at least 24 hours, although in some patients these effects may diminish towards the end of the 24 hour period. It may take several weeks before optimal blood pressure lowering effects are achieved.
- Abrupt withdrawal of Lotensin has not resulted in an abrupt increase in blood pressure; however, as with most antihypertensive drugs, it is best to discontinue Lotensin slowly.
