Abstract

The invention relates to a sustained-release preparation which takes guaiacol olycerin ether, pseudoephedrine or salt which is physiologically accepted by pseudoephedrine, and dextromethorphan or salt which is physiologically accepted by dextromethorphan as active ingredients. The sustained-release preparation of the invention not only can fully overcome relative symptoms such as cold and express the effect of synergy of compound medicines, but also the release and absorption of three active ingredients of the sustained-release preparation can reach synchronization, and the expected medicine release behavior can be gained inside and outside a human body. The medicine release behavior can reduce the times of taking medicine (from 4 times each day to 2 times each day, i.e. respectively taking medicine once in the morning and in the evening). The preparation is characterized in that times of taking medicine are reduced, the medicine can be slowly released in the human body, the blood concentration is stable, the fluctuation is small, the bioavailability is high, and the safety is high.

Description

technical field [0001] The invention relates to a sustained-release preparation with guaiacol glyceryl ether, pseudoephedrine or a physiologically acceptable salt thereof and dextromethorphan or a physiologically acceptable salt thereof as active components, and belongs to the field of medicine. Background technique [0002] A cold is an infection of the upper respiratory tract mucosa caused by many different types of viruses. The main symptoms are nasal congestion, sneezing, mild sore throat, and fever. Systemic symptoms include general discomfort, headache, and myalgia. Because there is no specific treatment at all, it is not necessary to make the virus firm, and only symptomatic treatment can be used to promote the relief of many symptoms of the cold. Since there is still no one drug to alleviate the coexisting symptoms, various compound preparations have been listed one after another. These compound preparations are composed of drugs with different curative effects to r...
