Unistar 75 Capsule is a combination of blood-thinning agent and cholesterol-lowering agent, primarily used to prevent myocardial infarction (heart attack), stroke or peripheral vascular disease. It is also used to lower abnormally elevated cholesterol or fat levels (hyperlipidaemia or dyslipidaemia) in the body. A heart attack occurs when a blood clot blocks the blood flow to the heart. This blockage of arteries is often an accumulation of fat, cholesterol and other substances, which form a plaque in the arteries that feed the heart (coronary arteries).
