Description

Technical field:

[0001] The invention relates to a drug sustained-release agent and a preparation method thereof, in particular to a 5-aminosalicylic acid sustained-release dosage form and an assembly method thereof. Background technique:

[0002] With the high development of modern medicine, people pay more and more attention to the research and application of drug controlled release system in medicine. Therefore, it has always been the focus of research to seek drugs with advantages such as long-acting, high efficiency, low toxicity, sustained release, good selectivity, and small side effects. Based on the drug sustained-release dosage form, when administered, it can maintain a specific concentration at a point of action for a long time and has fewer side effects, so it has the following advantages: (1) slow drug release and prolonged effect; (2) reduce toxicity (3) reduce side effects; (4) enhance selectivity; improve efficacy; (5) easy to use, etc.
