Benzil Tablet (Benazepril) | Used to Treat High Blood Pressure and Heart Failure
Benzil Tablet (Benazepril) is an ACE (angiotensin-converting enzyme) inhibitor used to treat high blood pressure (hypertension) and heart failure. It helps relax blood vessels, improve blood flow, and reduce strain on the heart.
Product Overview
Benzil Tablet is a highly effective, nonsulfhydryl angiotensin-converting enzyme (ACE) inhibitor containing Benazepril Hydrochloride. Benzil Tablet is primarily indicated as a baseline clinical intervention for the management of hypertension (high blood pressure) and as an adjunctive therapy in managing chronic heart failure. As a prodrug, it undergoes rapid hepatic conversion to its active metabolite, delivering sustained, 24-hour cardiovascular protection by dilating systemic arteries and reducing total cardiac workload.
Product Composition
- Active Ingredient: Benazepril Hydrochloride (Commonly available in oral tablet strengths such as 5 mg).
- Inactive Components: Typically includes lactose monohydrate, microcrystalline cellulose, corn starch, crospovidone, zinc stearate, and hypromellose within its film coating.
Product Specification

Mechanism of Action
The clinical efficacy of Benzil Tablet relies on its precise targeting of the renin-angiotensin-aldosterone system (RAAS) to manage cardiovascular stress:
- Inhibition of Angiotensin II: The active metabolite, benazeprilat, binds to and inhibits the angiotensin-converting enzyme. This prevents the converting step that turns inactive Angiotensin I into the potent vasoconstrictor Angiotensin II.
- Widespread Vasodilation: By suppressing Angiotensin II levels, it relaxes vascular smooth muscles. This results in direct dilation of peripheral arteries, lower systemic vascular resistance, and a smooth reduction in blood pressure.
- Reduction of Aldosterone Secretion: Lowered Angiotensin II stops the adrenal cortex from secreting aldosterone. This decreases renal sodium and water reabsorption, reducing total circulating blood volume without depleting potassium levels.
- Bradykinin Potentiation: ACE is also responsible for breaking down bradykinin (a natural structural vasodilator). By blocking this breakdown process, it raises local bradykinin levels, further assisting artery dilation.
Key Benefits
- Sustained Blood Pressure Lowering: Provides dependable, once-daily blood pressure control, significantly dropping the long-term risk of stroke or myocardial infarction.
- Excellent Renal Protection: Relaxes the efferent arterioles in the kidneys, lowering intraglomerular pressure to slow down diabetic nephropathy and kidney decline.
- Reduces Cardiac Afterload: Makes it easier for a failing heart to pump blood by lowering systemic arterial resistance, improving overall exercise tolerance.
- Balanced Dual Clearance: Its equal removal via liver and kidney pathways makes it safer for patients with mild to moderate kidney impairment than drugs cleared strictly by the kidneys.
- Prevents Vascular Remodeling: Minimizes the long-term structural thickening of heart muscle tissues (cardiac hypertrophy) caused by chronic high blood pressure.
Precautions
| Precaution | Description |
|---|---|
| Kidney Disease | Use carefully; may require regular kidney function monitoring. |
| High Potassium Levels | Can increase potassium; avoid potassium supplements unless advised. |
| Dehydration | May cause low blood pressure if dehydrated. |
| Pregnancy | Not recommended; can harm the developing baby. |
| Breastfeeding | Use only if clearly advised by a healthcare professional. |
| Surgery/Anesthesia | Inform doctor before any surgical procedures. |
| Allergy | Do not use if allergic to ACE inhibitors. |
Important Points
- Take exactly as prescribed by your doctor.
- Monitor blood pressure and kidney function regularly.
- Avoid sudden discontinuation without medical advice.
- Report dizziness, swelling, or persistent cough immediately.
Usage
Dosage and administration for this systemic cardiovascular medication must be personalized under regular clinical evaluation. Benzil Tablet should be taken at the same time every day to maintain steady drug levels and prevent sudden fluctuations in blood pressure.
Uses
Essential Hypertension: Prescribed as a primary baseline or combination therapy to lower high blood pressure and reduce the long-term risk of fatal strokes and heart attacks.
Chronic Heart Failure Management: Used alongside other cardiac medications to reduce structural strain on the heart muscle, making it easier to pump blood and improving survival rates.
Diabetic Nephropathy Protection: Utilized in hypertensive patients with type 2 diabetes to lower pressure in kidney capillaries, slowing down progressive kidney damage.
Post-Myocardial Infarction Recovery: Administered post-heart attack to help stabilize cardiac output and prevent dangerous thinning or stretching of the heart wall tissues.
Chronic Kidney Disease Adjunct: Helps reduce high protein levels in the urine (proteinuria) in individuals with non-diabetic kidney conditions.

FAQs
Q: What is Benzil Tablet used for?
A: Benzil Tablet (Benazepril) is used to treat high blood pressure (hypertension), chronic kidney disease, and as an adjunct therapy in the management of heart failure. It also helps slow the progression of kidney disease in patients with diabetes and hypertension.
Q: How does Benazepril work?
A: Benazepril works by blocking the ACE enzyme responsible for converting angiotensin I to angiotensin II, a potent vasoconstrictor that causes blood vessels to narrow. By inhibiting this process, Benazepril causes blood vessels to relax and widen, reducing the workload on the heart and lowering blood pressure.
Q: How should I take Benzil Tablet?
A: Benzil Tablet can be taken with or without food at the same time each day. Swallow the tablet whole with a full glass of water. Take it exactly as prescribed by your doctor and do not alter the dose without medical advice.
Q: What are the common side effects of Benzil Tablet?
A: Common side effects include a dry persistent cough, dizziness, headache, fatigue, nausea, and low blood pressure. Contact your doctor if any side effects become severe or persistent.
Q: Can Benzil Tablet cause a persistent cough?
A: Yes. A dry persistent cough is one of the most common side effects of Benazepril and other ACE inhibitors. If the cough becomes bothersome, consult your doctor as an alternative medication such as an angiotensin receptor blocker (ARB) may be recommended.
Q: Can Benzil Tablet protect the kidneys?
A: Yes. Benazepril helps slow the progression of kidney disease by reducing pressure within the kidney's filtration system. This makes it particularly beneficial for patients with hypertension associated with diabetes and chronic kidney disease, helping to preserve kidney function over time.
Q: Can Benzil Tablet affect potassium levels?
A: Yes. Benazepril can cause elevated potassium levels (hyperkalaemia) in some patients, particularly those with kidney disease or those taking potassium supplements or potassium-sparing diuretics. Regular monitoring of potassium levels is recommended during treatment.
Q: Who should not take Benzil Tablet?
A: Benzil Tablet should not be taken by patients who are pregnant, have a history of angioedema, have severe kidney or liver disease, or are allergic to Benazepril or other ACE inhibitors. Always inform your doctor of your full medical history before starting treatment.
