Generic Medicines for High Blood Pressure: Safety, Types & Benefits 

Introduction

Hypertension means an increase in blood pressure, i.e., greater than 140/90 mmHg. This happens when the blood pushes against the arteries at high pressure. People with hypertension may not feel any symptoms. But very high blood pressure can cause headaches, chest pain, and blurred vision. Severe hypertension can cause major complications like heart disease, stroke, etc¹. 

Appropriate treatment is important to prevent complications of hypertension, and the condition usually requires long-term treatment². Since high blood pressure requires long-term treatment, generic high blood pressure medicines can help reduce the treatment cost and encourage patients to take medicines consistently, leading to better blood pressure control³.

Why Are More Patients Switching to Generic Blood Pressure Medicines?

A generic drug is an approved form of the brand drug that mimics the branded drug in its safety, effectiveness, dosage and route of administration⁴. Many people with high blood pressure prefer switching from branded medicines to generics, which provide the same clinical effect at a lower cost. As hypertension is a long-term disease condition, affordability plays an important role in helping patients take their medications regularly. Doctors recommend generic medicines when an approved generic medicine is available in the market. 

Reasons to switch to generic hypertension drugs can be as follows⁵:

• Reduced medication costs: Hypertension is a long-term disease and may require medicines for a lifetime. Lower cost reduces the financial burden on the patients.  
• Same effectiveness as brand-name medicines: The same active ingredient is present in the generic medicine as compared to the brand-name medicine. Differences are only due to changes in the inactive ingredients, appearance, packaging, etc. 
• Better medication adherence: Due to increased medication costs, many patients skip doses. Affordability helps patients to refill prescriptions regularly and continue the long-term treatment. 
• Wider availability: Generic medicines are often available from multiple manufacturers and at more pharmacies, making them easier to access and obtain regularly. 

Types of Generic Medicines for High Blood Pressure

There are several types of generic high blood pressure medicines available. Each belongs to a different drug class and lowers blood pressure in a different way. Your doctor will choose the most suitable medicine based on your blood pressure, age, overall health, and other medical conditions. As per the regulatory authorities, these medicines are categorized as follows^6,7:

1. Angiotensin-Converting Enzyme (ACE) Inhibitors

• Captopril
• Enalapril 
• Lisinopril 
• Ramipril 

How do they work? 

These medicines reduce the production of a hormone called angiotensin II, which normally causes constriction of  blood vessels. 

2. Angiotensin II Receptor Blockers (ARBs)

• Losartan
• Valsartan 
• Telmisartan

How do they work? 

Instead of reducing the production of angiotensin II, ARBs prevent it from attaching to its receptors. This keeps blood vessels relaxed and helps lower blood pressure. 

3. Calcium Channel Blockers (CCBs)

• Amlodipine 
• Diltiazem 
• Verapamil 

How do they work? 

These medicines reduce the amount of calcium entering the muscle cells of the heart and blood vessels. As a result, blood vessels relax, making it easier for blood to circulate. 

4. Diuretics 

• Hydrochlorothiazide 
• Chlorthalidone
• Indapamide

How do they work? 

Diuretics help the kidneys remove extra salt and water from the body through urine. This reduces the amount of fluid in the blood vessels, lowering blood pressure. 

5. Beta Blockers

• Metoprolol 
• Atenolol 
• Bisoprolol 

How do they work? 

Reduces the heart rate and the force of heart contraction. This helps reduce blood pressure.  

Are Generic Blood Pressure Medicines Safe and Effective?

Generic medicines used to treat high blood pressure are considered safe, effective, and reliable once they have been approved by regulatory authorities. Before a generic medicine becomes available to patients, it undergoes a thorough scientific evaluation to confirm that it performs in the same way as the original brand-name medicine. This means it must contain the same active ingredient, be available in the same strength and dosage form (such as a tablet or capsule) and be administered in the same way. It must also show that the body absorbs and uses the medicine similarly to the branded product, ensuring that patients receive the same blood pressure-lowering effect. 

In addition to proving effectiveness, manufacturers must comply with strict quality standards during production. Every batch of an approved generic medicine is expected to meet the same manufacturing, purity, and quality requirements as the corresponding brand-name medicine. Therefore, patients can use approved generic blood pressure medicines with confidence, knowing they provide effective blood pressure control at a more affordable cost^4,5. 

Side Effects of Generic Blood Pressure Medicines

All blood pressure medicines have side effects. Mild side effects may improve over time. Some of the common side effects of blood pressure medicines include⁸:

• Constipation or diarrhoea 
• Coughing 
• Nervousness 
• Fatigue, feeling tired 
• Skin rashes 
• Headache 
• Dizziness or light-headedness

• Erection issues 

Contact your healthcare provider as soon as you observe any side effects. Changes in the dose of the medicines can help reduce the side effects. Do not stop or skip any medicines on your own. 

Tips for Taking Generic Blood Pressure Medicines Safely

• Check your blood pressure regularly at home. If abnormal, report to your healthcare physician

Although hypertension has no symptoms, regular blood pressure check-ups are important. Regular monitoring by a healthcare professional is particularly needed if you have factors that increase your risk of having hypertension, like a sedentary lifestyle, an unhealthy diet typically high in sodium, excessive body weight, smoking or alcohol habit, or a family history.  

Immediate medical attention may be needed in the following situations: 

• If your BP reading is higher than 180/90mmHg. 
• If you notice symptoms like severe headache, sweating, palpitations, numbness, weakness, blurred vision, difficulty in speaking or chest pain.
