Abstract

Naproxen (Naprosyn - Syntex) and ketoprofen (Orudis - M & B) are new drugs for treating various forms of arthropathy. For both drugs the manufacturers claim good anti-inflammatory activity with a low incidence of unwanted effects, particularly gastric irritation, in comparison with other non-steroidal anti-inflammatory drugs. If these claims can be substantiated these preparations would be valuable. Like aspirin and other non-steroidal anti-inflammatory drugs they both inhibit prostaglandin synthesis. Both are chemically related to other such drugs, for example ibuprofen (Brufen - Boots).
