Atenodip SR Capsule (Sustained Release)

Atenodip SR Capsule (Sustained Release) is manufactured by Incepta Pharmaceuticals Limited. Atenodip SR Capsule (Sustained Release) contains 50 mg+20 mg Atenolol + Nifedipine. It is Combined antihypertensive preparations class drug.

Atenolol belongs to a group of medicines called beta-blockers. It has an effect on the heart by blocking the action of chemicals called noradrenaline and adrenaline on beta receptor and control its rate and rhythm of beating. By reducing the heart rate and the force of muscle contraction, atenolol reduces the need of heart muscle for oxygen (demand). Because angina occurs when oxygen demand of the heart exceeds supply, atenolol is helpful in treating angina.

Nifedipine belongs to a group of medicines called calcium-channel blockers. These medicines block the transport of calcium, via holes called channels, into the smooth muscle cells lining the heart blood vessels and other blood vessels of the body. Blocking calcium transport relaxes the muscles of the blood vessels and makes them wider.


Management of hypertension where therapy with either a calcium channel blocker or a beta-blocking drug proves inadequate.

Management of chronic stable angina pectoris where therapy with calcium channel blocker or a β-adrenoceptor blocking drug proves inadequate.

  • Others: fatigue


Due to its beta-blocker component this combination may increase the number and duration of angina attacks in patients with Prinzmetal's angina due to unopposed alpha receptor mediated coronary artery vasoconstriction. Due to its negative effect on conduction time, caution must be exercised if it is given to patients with first degree heart block.

Atenodip SR


This combination must not be used in conjunction with calcium channel blockers with negative inotropic effects. eg. verapamil, diltiazem. Concomitant therapy with additional dihydropyridines, e.g. nifedipine, may increase the risk of hypotension, and cardiac failure may occur in patients with latent cardiac insufficiency.

This combination should not be used in patients with any of the following conditions: known hypersensitivity to either active component, or any other excipient or other dihydropyridines. Bradycardia; cardiogenic shock; hypotension; metabolic acidosis; severe peripheral arterial circulatory disturbances; second or third degree heart block; sick sinus syndrome; untreated phaeochromocytoma; uncontrolled heart failure; women capable of childbearing or during pregnancy or during lactation; patients with clinically significant aortic stenosis; patients with marked renal impairment. This combination should not be used for secondary prevention of myocardial infarction.

Special Warning

Use in Children: Safety and effectiveness in pediatric patients have not been established.

Acute Overdose

Symptoms: Bradycardia, hypoglycaemia, bronchospasm, hypotension and acute cardiac failure.
