The analgesic and antipyretic effects of EB-382 as a new non-steroidal antiinflammatory agent were examined in mice and rats. EB-382 had an equipotent inhibition to ibuprofen on the writhing syndrome caused by acetic acid, phenylquinone and acetylcholine in mice, but phenylbutazone was less potent in these experiments. EB-382 had a much more potent inhibition on the pain by the Randall-Selitto method and silver nitrate-induced arthritic pain in rats than ibuprofen and phenylbutazone. EB-382 had no analgesic effect on the pain of non-treated foot by the Randall-Selitto method in rats and by the hot-plate method in mice. EB-382 had a much more potent inhibition on the yeast-induced chronic inflammatory and adjuvant arthritic pains in rats than ibuprofen and phenylbutazone. The antipyretic activity of EB-382 was almost equipotent to that of ibuprofen in rats. EB-382 had no effect on the normal body temperature in rats, which was different from aminopyrine. The above results suggest that EB-382 will be a useful analgesic agent with an antipyretic antiinflammatory activity in clinical studies. 相似文献

The antiinflammatory, analgesic and antipyretic activities of 3-formylamino-7-methylsulfonylamino-6-phenoxy-4H-1-benzopyran-4-on e (T-614, CAS 123663-49-0) were investigated in various animal models and compared with those of nimesulide, indomethacin and ibuprofen. The antiinflammatory potency of T-614 on carrageenin-induced paw edema, paper disk granuloma and established adjuvant arthritis was greater than that of ibuprofen, but slightly lower than those of nimesulide and indomethacin. In acute inflammatory models, unlike indomethacin, T-614 suppressed the edemas provoked by dextran and bromelain in rats, but its inhibitory action on ultraviolet erythema in guinea-pigs was weak. Although the analgesic activity of T-614 was hardly demonstrated in writhing tests in mice, its potency against the inflammatory pain such as Randall-Selitto test, adjuvant-induced hyperalgesia and antigen-induced arthritic pain in rats was superior to that of ibuprofen. Moreover, it had a potent analgesic effect on urate-induced synovitis in dogs. T-614 exerted a prompt and strong antipyretic effect in both yeast-induced febrile rats and lipopolysaccharide-induced febrile rabbits. T-614 had virtually no gastrointestinal ulcerogenic action and did not affect water and sodium excretion in rats. T-614 is a novel antiinflammatory compound with different pharmacological properties from that of the reference drugs. 相似文献

In the present study, 70% ethanol extract of Mimusops elengi Linn. bark was assessed for antiinflammatory, analgesic and antipyretic activities in animals. The antiinflammatory activity of ethanol extract of Mimusops elengi (200 mg/kg, p.o) was evaluated using carrageenan-induced paw edema and cotton pellet-induced granuloma models. Analgesic effect was evaluated using acetic acid-induced writhing and Eddy's hot plate models and antipyretic activity was assessed by Brewer's yeast-induced pyrexia in rats. The ethanol extract of Mimusops elengi (200 mg/kg, p.o) significantly inhibited the carrageenan-induced paw oedema at 3rd and 4th h and in cotton pellet model it reduced the transudative weight and little extent of granuloma weight. In analgesic models the ethanol extract of Mimusops elengi decreases the acetic acid-induced writhing and it also reduces the rectal temperature in Brewer's yeast induced pyrexia. However, Mimusops elengi did not increase the latency time in the hot plate test. These results show that ethanol extract of Mimusops elengi has an antiinflammatory, analgesic and antipyretic activity. 相似文献

The antiinflammatory activity of the novel pyrrolidin-2-one derivative N-methoxy-3-(3,5-di-tert-butyl-4-hydroxybenzylidene)pyrrolidin-2-o ne (E-5110) was investigated and compared with those of indomethacin and piroxicam in various antiinflammatory, analgesic and antipyretic animal models. The acute antiinflammatory activity of E-5110 on the carrageenin paw edema was similar to that of indomethacin, and half that of piroxicam. The chronic inflammatory responses in established adjuvant- and type II collagen-induced arthritis, which are widely used models of rheumatoid arthritis, were suppressed as effectively by E-5110 as by indomethacin and piroxicam. E-5110 decreased the pleural exudate volume and inhibited leucocyte infiltration in a reversed passive Arthus reaction more potently than indomethacin, suggesting that mediators other than prostaglandin E2 may play an important role in this inflammatory process. The analgesic potency of E-5110 against inflammatory pain was similar to that of indomethacin or piroxicam, but the antipyretic activity of E-5110 was more potent than that of the reference drugs. The ulcerogenic effect of E-5110 on rat gastric mucosa was less than those of indomethacin and piroxicam. In conclusion, E-5110 is a very potent antiinflammatory compound acting against various types of inflammation, and has a favorable therapeutic index. 相似文献

In a double-blind cross-over study on 22 healthy subjects the analgesic efficacies of the antipyretic analgesic drugs ibuprofen, dipyrone and paracetamol were tested against placebo using a model of experimentally induced pain. To this purpose interdigital webs were pinched repeatedly for 2 min periods. The painfulness of these stimuli was assessed by the subjects on an electronically controlled visual analogue scale at 10 sec intervals. In addition to the subjective pain ratings the stimulus induced reflex diminution of the blood flow in the stimulated hand was measured with photoplethysmography and laser Doppler flow analysis. The flare response around the stimulated area was assessed with infrared thermography. In this assay system ibuprofen and dipyrone, but not paracetamol, showed statistically significant analgesic effects by preventing hyperalgesia which is normally induced by the repeated stimulation of a skin site. This hypoalgesic effect was not related to the subjective impression of the subjects of the analgesic potency of the respective drug. Sympathetic reflex vasoconstriction was not quantitatively related to the drug induced hypoalgesia. Ibuprofen and, to a minor extent, the other antipyretic analgesic drugs also diminished the stimulus induced flare reaction around the stimulated skin sites. 相似文献
