Seloken ZOC Extended-Release Tablets are used to treat high blood pressure and certain heart conditions. They work by
lowering the heart rate and reducing cardiac workload, which improves the efficiency of blood pumping.
In Saudi Arabia Seloken ZOC contains Metoprolol Succinate, a selective beta-1 blocker. Its extended-release
formulation provides stable therapeutic coverage throughout the day. It is commonly prescribed for blood pressure
control, prevention of angina, and support in chronic heart failure under regular medical supervision.
