Amlodipine

Amlodipine is a Calcium Channel Blocker (CCB). It works by reducing calcium flow into the smooth muscle cells of blood vessel walls, causing blood vessels to relax and widen. This improves blood flow and lowers blood pressure.

Amlodipine has an exceptionally long half-life (30-50 hours), meaning one daily dose provides smooth, consistent blood pressure control over the full 24-hour period — no fluctuations throughout the day.

Amlodipine isn't just for high blood pressure.

💊 Hypertension — The primary indication. Amlodipine effectively reduces both systolic and diastolic pressure. Can be used alone or combined with other blood pressure drug classes.

💊 Angina (chest pain from coronary artery disease) — Amlodipine dilates coronary arteries and reduces the heart's workload, relieving chest pain from reduced blood flow to the heart.

💊 Raynaud's disease — A condition where blood vessels in the fingers and toes constrict in response to cold. Amlodipine helps by dilating these vessels.

Amlopine and Ambes both contain the same active ingredient: Amlodipine. They differ only in brand and manufacturer.

Bottom line: Same drug, same effectiveness. Choose based on brand familiarity or budget. Consult a pharmacist for guidance.

💊 Dosage — Starting dose is typically 5 mg once daily. May be increased to 10 mg if needed. Elderly patients often start at 2.5 mg.

⏰ Timing — Take at the same time every day, morning or evening. Can be taken with or without food. Consistency is what matters most.

🚫 Never stop on your own — Even if blood pressure normalises. Stopping abruptly can cause pressure to rebound. Any dose changes must be gradual and medically supervised.

🍊 Grapefruit — Avoid grapefruit juice while taking Amlodipine, as it may increase drug levels in the blood.

Amlodipine has a strong safety profile. Most side effects are mild and often improve as the body adjusts.

Common side effects:

• Ankle swelling (Peripheral Oedema) — Most common, especially at 10 mg. Caused by blood vessel dilation, not kidney problems. Elevating legs while resting can help.
• Facial flushing — Due to blood vessel dilation. Usually improves within 1-2 weeks.
• Headache — Common initially, usually resolves on its own.
• Dizziness — Especially when first starting.

Important: Amlodipine does not cause dry cough — a key advantage over ACE Inhibitors (like Enalapril), which cause dry cough in 10-15% of users.

At Intimo Life, we offer blood pressure medications across multiple classes.

Amlodipine (CCB) vs Enalapril (ACE Inhibitor) — Anapril / Enaril

• Amlodipine doesn't cause dry cough (key advantage) / ACE Inhibitors cause cough in 10-15%
• ACE Inhibitors offer better heart and kidney protection, especially for diabetic patients

Amlodipine (CCB) vs Losartan (ARB) — Loranta

• Neither causes dry cough / Losartan offers kidney protection and slightly lowers uric acid — suitable for patients with gout
• Amlodipine requires no dose adjustment for kidney patients

Amlodipine (CCB) vs Doxazosin (Alpha Blocker) — Cardura XL / Cazosin

• Doxazosin also helps with enlarged prostate symptoms — ideal for men with both conditions

✅ Common safe combinations — Other blood pressure medications, especially ACE Inhibitors or ARBs (e.g. Amlodipine + Losartan is a popular combination) / cholesterol medication (Statins) / diabetes medication

⚠️ Caution needed — Avoid grapefruit juice / use care with ED medication (e.g. Sildenafil) as both lower blood pressure — may cause excessive drops. Consult a pharmacist first / caution with high-dose Simvastatin (above 20 mg) combined with Amlodipine due to increased muscle pain risk

A common concern among men taking blood pressure medication.

The good news: Amlodipine is among the blood pressure medications with the least impact on sexual function, unlike Beta Blockers or certain diuretics which may have more noticeable effects.

If you experience erectile difficulties while taking blood pressure medication, do not stop the medication. Consult a pharmacist about switching drug classes or adding ED treatment.

Blood pressure medication works best alongside lifestyle changes.

🧂 Reduce sodium — No more than 2,000 mg/day. Cut back on soy sauce, fish sauce, and processed foods.

🏃 Exercise regularly — 150 minutes per week, moderate intensity.

⚖️ Maintain healthy weight — Every 1 kg lost reduces blood pressure by approximately 1 mmHg.

📏 Monitor at home — Measure morning and evening. Keep a log for your pharmacist or doctor.

🚭 Quit smoking, limit alcohol — Both accelerate arterial damage.

🚨 See a doctor if — Significant or painful ankle swelling / severe dizziness or fainting / unusually rapid heartbeat or palpitations / blood pressure not decreasing despite consistent medication / chest pain or breathing difficulty / you want to adjust or change your medication
