Ivabradine
Pharmacology
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.
Dosage Administration
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).
Side Effects
Visual symptoms, blurred vision, bradycardia, 1st degree AV block, ventricular extrasystoles, headaches, and dizziness.
Pregnancy And Lactation
Studies in rats have shown no effect on fertility in males and females. There are no or limited amount of data from the use of ivabradine in pregnant women. Therefore, ivabradine is contra indicated during pregnancy. Animal studies indicate that ivabradine is excreted in milk. Therefore, ivabradine is contra-indicated during breast-feeding.
