Anti-inflammatory, analgesic, and antipyretic pharmaceutical composition

Abstract

A new anti-inflammatory, analgesic, and antipyretic pharmaceutical composition is disclosed which contains a 3,5-di-tert-butyl-4-hydroxystyrene derivative of the formula: ##STR1## wherein R.sup.1 stands for a group represented by COR.sup.3 [R.sup.3 denotes a group of OR.sup.4 (R.sup.4 is a hydrogen atom or an alkyl group with C.sub.1 .about.C.sub.4), an alkyl group with C.sub.1 .about.C.sub.3, a phenyl group, or an amino group], a nitro group, or an alkylsulfonyl group represented by SO.sub.2 R.sup.5 (R.sup.5 is an alkyl group with C.sub.1 .about.C.sub.3); and R.sup.2 stands for a hydrogen atom, an alkyl group with C.sub.1 .about.C.sub.4, a hydroxyalkyl group with C.sub.1 .about.C.sub.4, a cyano group, or an acyl group represented by COR.sup.6 (R.sup.6 is an alkyl group with C.sub.1 .about.C.sub.3), or its pharmaceutically acceptable salt as an active ingredient in association with pharmaceutical excipients. The pharmaceutical composition has excellent anti-inflammatory, analgesic, and antipyretic activities and low toxicity.
