Abstract

The invention relates to a compound paracetamol and chlorphenamine slow release tablet and method for preparation, which comprises paracetamol, chlorpheniramine maleate, caffeine, artificial ox gallstone and slow release matrix material, lubricating agent, core and damp-proof membrane consisting binding agent and flow adjuvant, wherein the proportion of the composition is, acetaminopher 30%-80%, chlorpheniramine maleate 0.5%-4%, caffeine 2%-10%, taurine 1%-10%.

Description

technical field [0001] The invention relates to a compound paracetamol sustained-release tablet and a preparation method thereof. Background technique [0002] The granules and capsules for treating colds made of acetaminophen, chlorpheniramine maleate, caffeine, and artificial bezoar composition have been included in the non-prescription drug management range by the state. Due to the short half-life of the components in the composition, the half-life of paracetamol is 75-180 minutes, the half-life of chlorpheniramine maleate is 2-15 hours, and the half-life of caffeine is 3-4 hours. Due to the short half-life of the components, the absorption is fast after oral administration, so the elimination in the body is also fast. In order to maintain the effective blood concentration, three times of daily administration should be taken in a balanced manner, which will cause peaks and valleys in the blood, which will significantly affect the therapeutic effect, and It is inconvenien...
