It is commonly prescribed to prevent heart disease, stroke, and other cardiovascular conditions in patients with high cholesterol or risk factors such as diabetes, obesity, or a family history of heart problems. ROSTAB 20 mg works by blocking an enzyme in the liver that produces cholesterol, helping maintain a healthy lipid balance in the body.
