Analgesic and antipyretic effects of proglumetacin maleate (PGM), a new indomethacin (IND) derivative, were investigated in comparison with those of IND on an equimolar-dose basis. The suppression of phenylquinone-induced writhing in mice by PGM was about 0.8 and 2 times as potent as that by IND when given 1 and 4 hr before the phenylquinone injection, respectively. The analgesic activity of PGM in rat silver nitrate arthritis was about 1.5 times more potent than that of IND. PGM was slightly less active in rat adjuvant arthritic pain than IND. On the other hand, PGM provoked a dose-dependent antipyretic effect on the yeast-induced fever in rats within the dose range without affecting the normal body temperature. Furthermore, PGM showed a significant antipyretic effect on LPS-febrile rabbits. Generally, the antipyretic effect of PGM was moderate as compared with that of IND. These analgesic and antipyretic actions of orally administered PGM may be mainly due to its active metabolite, IND. The above results indicate that PGM may be useful for inflammatory diseases associated with pain and/or fever.
