Pravastatin sodium is widely used in the medical field primarily for managing cholesterol levels. It is prescribed to lower high levels of LDL cholesterol, often referred to as "bad" cholesterol, and to increase HDL cholesterol, known as "good" cholesterol. This helps reduce the risk of heart disease, heart attacks, and strokes in individuals with high cholesterol or those at risk of cardiovascular issues. It is also used to slow the progression of atherosclerosis, a condition where arteries become clogged with fatty deposits. Patients with a history of heart-related conditions or those who have undergone certain procedures like angioplasty may be prescribed this medication as a preventive measure. It is typically taken orally and is often combined with lifestyle changes such as a healthy diet and regular exercise for optimal results.
