Abstract

The invention discloses a new formulation of novel nonsteroidal antiinflammatory medicament-zaltoprofen, namely an enteric sustained-release preparation containing zaltoprofen. Matrix which is insoluble in water and is insoluble in gastrointestinal fluid is used as a sustained-release auxiliary material to prepare the enteric sustained-release preparation. The enteric sustained-release preparation prepared in the invention has no fast release phenomenon of the medicament, and the repeatability of in vitro medicament release action of the preparation with different batches is good, so as to bebeneficial to keep in-vivo plasma concentration of a patient stable after taking the medicament.
