ASTIN D 10MG TABLET helps lower bad cholesterol (low-density lipoprotein-LDL) and triglycerides (fats) levels. Hence, it reduces the risk of heart attack and stroke in the future. It contains Atorvastatin and Cholecalciferol (Vitamin D3), which work by blocking liver enzymes, causing the liver to make less cholesterol. So, it increases the uptake and breakdown by the liver of cholesterol already in the blood. Thus, it lowers the levels of lipids known as cholesterol and triglycerides in the blood when lifestyle changes (like a low-fat diet) on their own have failed. It reduces the bad cholesterol and increases the good cholesterol by blocking our body's production of bad cholesterol. It also improves your body's ability to remove it from your blood. In some cases, you may experience allergic reactions, headache, blurred vision, pain, constipation, nausea, diarrhoea, muscle spasms, joint swelling, and back pain.
