Abstract

The invention provides a fluvastatin tablet containing an antiflatulent agent which is selected from dimeticone or simethicone. The fluvastatin tablet is characterized in that fluvastatin is dispersed on pharmaceutically applicable polymer carriers to achieve the aim of stabilization; and the polymer carriers are selected from one or more of polyethylene glycols, polyvidones, surfactants containing polyoxyethylene groups, water-soluble cellulose derivatives, organic acids, saccharides and alcohols. The fluvastatin tablet can effectively remove flatulence and symptom disorder caused by oral administration of fluvastatin.

Description

technical field [0001] The invention belongs to the field of biopharmaceuticals, and in particular relates to a fluvastatin tablet containing an antiflatulent agent, and also relates to a preparation method thereof. Background technique [0002] Statins (ie, HMG-CoA reductase inhibitors) are currently the main class of drugs clinically used to lower cholesterol. Currently clinically used statins include lovastatin, fluvastatin, rosuvastatin, pravastatin, atorvastatin and simvastatin. The most prominent and common side effect of statins is flatulence, which causes not only discomfort but also confusion of symptoms because its symptoms are similar to some symptoms of coronary heart disease. [0003] Antifoaming agents can be used to reduce flatulence, such as simethicone and simethicone, which can be used to treat flatulence and gas in the abdomen. Pharmaceutical compositions comprising an H2 antagonist such as famotidine, alginate and optionally an anti-flatulent amount of ...
