ISOKET RETARD 40 TABLETS - patient leaflet, side effects, dosage

1. what isoket retard is and what it is used for

Isoket Retard belongs to a group of medicines called organic nitrates. Organic nitrates work by widening the blood vessels in your heart to allow an increased amount of blood to flow to areas which need it.

Isoket Retard is used to prevent and treat angina pectoris. Angina usually feels like a tight pain in the chest, neck or arm area. The pain comes from the heart muscle and is a sign that part of it is not getting enough oxygen for the amount of work it is doing.
