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: <IMAGE> wherein R1 stands for a group represented by COR3 [R3 denotes a group of OR4 (R4 is a hydrogen atom or an alkyl group with C1 DIFFERENCE C4), an alkyl group with C1 DIFFERENCE C3, a phenyl group, or an amino group], a nitro group, or an alkylsulfonyl group represented by SO2R5 (R5 is an alkyl group with C1 DIFFERENCE C3); and R2 stands for a hydrogen atom, an alkyl group with C1 DIFFERENCE C4, a hydroxyalkyl group with C1 DIFFERENCE C4, a cyano group, or an acyl group represented by COR6 (R6 is an alkyl group with C1 DIFFERENCE C3), 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.
An anti-inflammatory, analgesic, and antipyretic pharmaceutical composition which comprises an effective amount of a 3,5-di-tert-butyl-4-hydroxystyrene derivative represented by the general formula: ##STR8## wherein R 1 stands for a group represented by --COOR 4 ; R 4 is a hydrogen atom or an alkyl group with C 1 ˜C 4 ; R 2 stands for an alkyl group with C 1 ˜C 4 , a hydroxyalkyl group with C 1 ˜C 4 , or an acyl group represented by --COR 6 ; and R 6 is an alkyl group with C 1 ˜C 3 or its pharmaceutically acceptable salt as an active ingredient in combination with pharmaceutical excipients.
