Norvasc vs Tenormin: Amlodipine vs Atenolol — Blood Pressure Medicines

Norvasc (Amlodipine) and Tenormin (Atenolol) lower blood pressure by very different mechanisms. Amlodipine is a calcium channel blocker that relaxes arteries; Atenolol is a beta-blocker that slows the heart. Treatment guidelines now generally prefer amlodipine as initial therapy for most adults, with beta-blockers used for specific indications.

Hamare expert ka khayal (Verdict)

For most adults newly diagnosed with high blood pressure in Pakistan — particularly South Asians and adults over 55 — Norvasc (Amlodipine) is the recommended first-line choice. Tenormin (Atenolol) remains useful after heart attack, in angina, in some arrhythmias, and in young patients with high resting heart rate. Only your doctor should choose and adjust BP medication.
