Notes:
Summary Plasma concentrations of pirprofen were measured in 11 elderly arthritic patients and 6 healthy young volunteers at the beginning and end of 8 days treatment with 400 mg doses twice daily. The mean ages of the two groups were 74.5 and 21.8 years, respectively. There were no statistically significant differences in peak concentrations, times to peak, areas under the curve or terminal elimination half-lives between the groups after single dosing. Repeated dosing increased plasma drug concentrations in both groups but the extent was as predicted from the single dose data. Again there were no statistically significant differences between the groups, although pre-dosing plasma concentrations were higher in the elderly compared with the young individuals. The results of this relatively small study suggest that advancing age and arthritic disease appear to have little influence on the pharmacokinetics of pirprofen and no modification in the dosage recommendation in elderly patients without overt renal or hepatic impairment is indicated.
