Application of papaya latex-induced rat paw inflammation: model for evaluation of slowly acting antiarthritic drugs.

Abstract:

:Papaya latex-induced rat paw inflammation model for evaluating antiinflammatory activity has been developed and reported earlier. A number of drugs viz. aspirin, indomethacin, piroxicam, ibuprofen, prednisolone, levamisole, chloroquine, and boswellic acids showed antiinflammatory activity in this model. As the last three drugs showing the activity belonged to the group of slowly acting antiarthritic drugs, this present study was undertaken to study in detail the sensitivity of this model for slowly acting, clinically effective, antiarthritic drugs viz. chloroquine, levamisole, penicillamine, aurothioglucose, cyclophosphamide, and boswellic acids. These drugs are known to show no appreciable activity in the known models of inflammation and arthritis. All these drugs tested in three graded doses showed dose-related significant antiinflammatory activity in this model, whereas those drugs in the carrageenan model tested in similar doses showed insignificant activity. Aspirin employed as a reference standard showed significant activity in both the models. Thus the slowly acting antiarthritic drugs will be identified as those displaying significant activity in the papaya latex model and insignificant activity in the carrageenan model and to be aspirin-like by their significant activity in both the above models of inflammation.
