The pharmacokinetic profile of 200 mg sustained-release flurbiprofen capsules was compared in nine elderly (mean age 84.2 years) and 10 young (mean age 38.1 years) patients with arthritis. After a single capsule, a 48 h plasma concentration profile was performed. The patients then took 1 capsule daily for a further 13 days with plasma levels of the drug being measured pre-dose on alternate days. Following ingestion of the last capsule, a further 48 hour plasma concentration profile was performed. These results were compared with each other and with computer predicted data obtained from dosing with 200 mg conventional flurbiprofen (as 100 mg b.d.). In both young and elderly patients, the two 48 h plasma concentration profiles confirmed the sustained-release characteristics of the capsule. There was no evidence of dose-dumping, although, in one elderly patient with a partial gastrectomy, higher plasma concentrations were observed. Inter- and intra-patient variability was acceptable. A steady-state was achieved within the predicted four days in both groups and there was no evidence of accumulation with the daily dosing interval. A mean steady-state level of approximately 6 micrograms/ml was achieved for both populations. Computer predicted data for 200 mg conventional flurbiprofen (as 100 mg b.d.) showed a pre-dose/peak range of 1-12 micrograms/ml. The pre-dose/peak ranges for the young and old patients were 4-10 micrograms/ml and 4-8 micrograms/ml respectively. One young patient developed a hypersensitivity reaction of moderate severity; one young and four elderly patients developed a low haemoglobin concentration during the study. No other changes in haematological or biochemical parameters were seen.
