Adult: The usual recommended starting dose of Ivabradine is 5 mg twice daily which may be increased after 3-4 weeks of treatment to 7.5 mg twice daily, depending on therapeutic response. Usual dose is 1 tablet in the morning and 1 tablet in the evening during meals. If the heart rate decreases persistently below 50 bpm at rest or if symptoms related to bradycardia, the dose must be adjusted downwards to 2.5 mg twice daily (one half of the 5 mg tablet twice daily). Treatment must be discontinued if heart rate remains below 50 bpm or symptoms of bradycardia persist.

Elderly: Consider a lower starting dose (2.5 mg twice daily i.e. one half 5 mg tablet twice daily).

Visual symptoms, blurred vision, bradycardia, 1st degree AV block, ventricular extrasystoles, headaches, and dizziness.

Symptomatic treatment of chronic stable angina pectoris in coronary artery disease patients with normal sinus rhythm. Ivabradine is indicated:

• In patients unable to tolerate or with a contra-indication to the use of beta-blockers or
• In combination with beta-blockers in patients inadequately controlled with an optimal beta-blocker dose and whose heart rate is > 60 bpm.

Ivabradine is a pure heart rate lowering agent. It acts by selective and specific inhibition of the cardiac pacemaker I f current that controls the spontaneous diastolic depolarization in the sinus node and regulates heart rate. By decreasing heart rate, Ivabradine decreases the cardiac workload and therefore oxygen consumption. Concomitantly, Ivabradine prolongs diastole allowing increased perfusion of coronary arteries and increased oxygen supply to the heart. The cardiac effects are specific to the sinus node with no effect on intra-atrial, atrioventricular or intraventricular conduction times, nor on myocardial contractility or ventricular repolarization.
