Description

technical field [0001] The invention relates to a pharmaceutical composition of bezafibrate double-release sustained-release capsules, a double-release sustained-release capsule and a preparation method thereof. Background technique [0002] Cardiovascular disease is one of the most threatening diseases to humans today, and its morbidity and mortality have surpassed tumor diseases and ranked first. Actively treating hyperlipidemia is an important means to prevent cardiovascular and cerebrovascular diseases and reduce mortality. Lipid-lowering drugs have become the focus of modern drug research. With the increasing number of patients with hyperlipidemia around the world, the market potential of lipid-lowering drugs is becoming more and more obvious, and its market competition is becoming more and more fierce. In the 1940s, phenoxyaromatic acid (fibrates) drugs were first listed on the market. Phenoxyaromatic acid drugs are broad-spectrum systemic lipid regulators, which are ...
