    Notes: Summary The influence of cimetidine on its own pharmacokinetics after subchronic administration was assessed in 8 healthy volunteers, aged 26–29 years. On control Day 1, each subject received cimetidine 300 mg i.v., and serum and urine samples were obtained. Each subject was initiated on cimetidine 600 mg b.i.d. orally for 2 weeks. There were 3 further study days repeated after 1 and 2 weeks of cimetidine dosing and 1 week after stopping cimetidine. There was no significant difference in the mean total body clearance of cimetidine among the 4 study days. Mean elimination t1/2β and Vβ were similarly unchanged. However mean renal clearance (CLR) and fe were significantly increased following 2 weeks of drug dosing (CLR 5.41 ml·min−1 kg−1; fe 0.61) compared to control (CLR 4.00 ml·min−1·kg−1; fe 0.48). Although the non renal clearance was reduced from control values of 4.29 to 3.51 ml·min−1·kg−1 following 2 weeks of dosing the difference was not significant. Dosage adjustment of cimetidine appears unnecessary after short-term dosing in the presence of normal renal function.

    Notes: Summary Salbutamol was administered to sixteen healthy male volunteers intravenously and by mouth in liquid, tablet, and capsule form using a Latin-Squares design. Pharmacokinetic parameters from intravenous data were similar to previously reported values obtained with oral administration, with a mean terminal half-life of 3.8 h and a mean clearance of 439 ml·min−1·1.73 m−2. Peak plasma concentrations of 10–20 ng·ml−1 were obtained 1–3 h following oral administration. The absolute bioavailability of each of the oral preparations was 44%. While statistically significant differences in lag time and time to peak concentration were noted among the various oral preparations, the drug is rapidly absorbed in all three dosage forms and the observed differences are unlikely to be of clinical significance.
