Indications

  • Essential hypertension
  • Angina pectoris
  • Post-MI patients
  • Refractory angina pectoris

Pharmacology

  • Fixed-dose combination of Amlodipine and Atenolol
  • Amlodipine is a dihydropyridine calcium antagonist
  • Amlodipine inhibits transmembrane influx of calcium ions into vascular smooth muscle and cardiac muscle
  • Amlodipine acts directly on vascular smooth muscle to reduce peripheral vascular resistance
  • Amlodipine reduces tone, decreases coronary vasoreactivity, and lowers cardiac demand
  • Atenolol is a cardioselective beta-blocker
  • Atenolol causes a reduction in blood pressure by lowering cardiac output
  • Atenolol decreases the plasma renin activity and sympathetic outflow from CNS
  • Atenolol reduces myocardial oxygen demand by its negative inotropic and negative chronotropic effects

Dosage & Administration

  • Recommended dosage: Amlodipine and Atenolol 5/25 mg tablet once daily
  • Dosage may be increased to 5/25 mg two tablets daily or as advised by physicians
  • Dosage should be individualized

Interaction

  • Disopyramide: Atenolol reduces the clearance of disopyramide by 20%
  • Additive negative inotropic effects on the heart may be produced
  • Ampicillin: may reduce Atenolol levels at doses of 1 gm and above
  • Oral antidiabetics and insulin: Beta-blockers may decrease tissue sensitivity to insulin and inhibit insulin secretion
