Acidic antiinflammatory agents--correlations of some physical, pharmacological and clinical data.

Abstract

Fifteen acidic antiinflammatory agents, for which some clinical data have previously been published, have been examined for their potency in the carrageenan-induced rat foot edema test, and for their acidity (pKa) and partition coefficients. Published serum half-life data and daily clinical (anti-arthritic) dose have been tabulated for these drugs and correlations between these various parameters are discussed. The rat foot edema carrageenan test has proved to be a fairly reliable predictor of clinical dose for most acidic antiinflammatory agents of moderate serum half-life.
