From an analysis of the above table it can be seen that: in a medium with pH of 6.8, the paracetamol serving as the main drug in the pediatric paracetamol and chlorpheniramine maleate granular preparation prepared by the invention is dissolved out by less than 5% within 5 minutes, and can reach more than 80% after 15 minutes.
According to the pediatric paracetamol, yellow and chlorphenamine maleate granule preparation, the popping candy is added into the medicine, so that the oral interestingness of children is increased; the raw materials are coated with powder to cover up the peculiar smell of the medicine, and the medicine is basically not released (the dissolution is less than 5%) after 3-5 minutes in the oral cavity, namely the delayed release of the medicine is realized; the drug-containing granules coated with the powder are 40 meshes in size, namely the required particle size is less than 40 meshes, otherwise the taste is affected, and the swallowing discomfort of children is caused. In addition, the preparation process of the pediatric paracetamol, atificial cow-bezoar and chlorphenamine maleate granules is simple, convenient to operate, low in production cost, suitable for industrial production, better in children oral administration adaptability and good in popularization and application values.
The embodiments of the present invention have been described in detail, but the embodiments are merely examples, and the present invention is not limited to the embodiments described above. Any equivalent modifications and substitutions to those skilled in the art are also within the scope of the present invention. Accordingly, equivalent changes and modifications made without departing from the spirit and scope of the present invention should be covered by the present invention.
