[Bioequivalence of phenylbutazone preparations following a single intramuscular administration].
Bioequivalence was estimated in 6 resp. 7 male volunteers for two combination drugs of phenylbutazone (Neuro-Elmedal, Sigma Elmedal) after intramuscular administration using a monopreparation as a standard. Plasma levels of phenylbutazone were assayed by high pressure liquid chromatography. With respect to rate and extent both combination drugs were identical to the mono drug.
