Abstract

The present invention relates to the field of medicine technology, in particular, it relates to a flurbiprofenbab preparation and its preparation method. Said preparation includes back lining layer, medicine storage layer and protecting film, said medicine storage layer is formed from flurbiprofen powder preparation or flurbiprofen emulsion, hydrophilic bab preparation matrix, osmotic acceleratorand additive. Its medicine-carrying quantity is large, moisture-holidng property and air permeability are good.

Description

Technical field: [0001] The invention relates to the technical field of medicine, and relates to a flurbiprofen cataplasm and a preparation method thereof. Background technique: [0002] Flurbiprofen (flurbiprofen) is a new non-steroidal anti-inflammatory drug with anti-inflammatory and analgesic effects. Effective and widely used for musculoskeletal and joint disorders such as rheumatism, rheumatoid arthritis, degenerative arthritis, osteoarthritis, ankylosing spondylitis; soft tissue disorders such as sprains and strains; mild pain relief such as dysmenorrhea and postoperative pain. But it, like other non-steroidal anti-inflammatory drugs, can easily cause gastrointestinal side effects such as peptic ulcer and bleeding when taken orally. The transdermal drug delivery preparation can increase the local drug concentration of flurbiprofen at the pain site, enhance the anti-inflammatory effect, and avoid adverse reactions of gastrointestinal drug delivery. There are flurbip...
