Suprofen sustained release kinetics in healthy male volunteers. 2nd communication: a multiple dose steady-state kinetics of suprofen sustained release tablets during 6 days in healthy male volunteers.

To 12 healthy male volunteers, who had given their consent, 11 administrations of alpha-methyl-4-(2-thienyl-carbonyl)phenylacetic acid (suprofen, Suprol) sustained release tablets 600 mg were given twice a day with a dosage interval of 12 h. It could be demonstrated that suprofen given as multiple dose application of sustained release tablets was well tolerated. Effective mean plasma levels were reached after the second dosage. There was no indication of accumulation nor accelerated elimination during the 6-day period. There was no statistically significant difference between the mean plasma curve after the last administration of the 6-day period and the mean plasma curve after the 3rd application. Also the AUC's in the respective intervals turned out not to be statistically significantly different from each other. Clinical and laboratory tests showed no clinically relevant deviations from the normal range. No adverse reactions whatsoever were observed.
