5. Uses of Pravastatin
Pravastatin (81093-37-0) is commonly used for lowering blood pressure, cholesterol drugs. As a reductase inhibitor, for a variety of models have reduced the role of hyperlipidemia, for lowering blood pressure, cholesterol, from the micro-organisms to be hydroxide. Pravastatin is one of the lower potency statins; but its increased hydrophilicity is thought to confer advantages such as minimal penetration through lipophilic membranes of peripheral cells, increased selectivity for hepatic tissues, and a reduction in side effects compared with lovastatin and simvastatin.
