Abstract

The present invention belongs to the field of medicine technology, in particular, it relates to a ketoprofen cataplasma preparation and its preparation method. The experiments of initial adhesion, paste content, excipient property, external release and external percutaneous test show that the invented ketoprofen cataplasma preparation can meet the requirements related to pharmacopeia.

Description

technical field [0001] The invention relates to the technical field of medicine, and relates to a ketoprofen cataplasm and a preparation method thereof. Background technique [0002] Ketoprofen (Ketoprofen) is a non-steroidal antipyretic analgesic anti-inflammatory drug (NSAID), has anti-inflammatory, analgesic, antipyretic effects, and is widely used clinically in the treatment of diseases such as rheumatism and rheumatoid arthritis. Similar to the adverse reactions of other non-steroidal antipyretic analgesic and anti-inflammatory drugs, oral administration of ketoprofen is also more likely to cause gastrointestinal reactions such as stomach pain, nausea, ulcers, and bleeding. The ketoprofen transdermal preparation can improve the local drug concentration of ketoprofen at the pain site, enhance the anti-inflammatory effect, avoid the gastrointestinal adverse reactions caused by oral administration, and can control the dosage by adjusting the area ...
