Abstract

The invention relates to a medicinal composition containing pitavastatin and telmisartan. The medicinal composition contains pitavastatin or a salt thereof, and telmisartan or a salt thereof. The medicinal composition has a synergistic effect in the field of the treatment of hyperlipidemia and hypertension, and is better than medicines in the prior art.

Description

technical field [0001] The invention belongs to the field of combined application of blood pressure-lowering and blood-lipid-lowering drugs, in particular to a pharmaceutical composition containing telmisartan and pitavastatin. Background technique [0002] Pitavastatin, a 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitor, can reduce the synthesis of mevalonate, thereby reducing the amount of cholesterol synthesis. Pitavastatin mainly acts on the liver, inhibits the synthesis of cholesterol in the liver, reduces the concentration of cholesterol in liver cells, promotes the concentration-dependent increase in the density and activity of low-density lipoprotein (LDL) receptors, accelerates the catabolism of LDL, and can reduce the concentration of low-density lipoprotein (LDL) receptors. The synthesis of high-density lipoprotein (VLDL) reduces the conversion of VLDL into LDL, thereby reducing the level of plasma low-density lipoprotein cholesterol (LDL-C). P...
