Pharmacokinetics of azlocillin after intramuscular application.
The first pharmacokinetic data are reported of azlocillin injected intramuscularly to adult probands. The blood serum and urinary levels of azlocillin were determined microbiologically in 8 healthy volunteers after intramuscular injection of 2 grams. Peak serum levels of azlocillin were found by the end of hour 1 after injection, average level was (55.06 +/- 10.25) mg/l. At hour 2 the average level was (33.64 +/- 6.46) mg/l. and at hour 4, (9.47 +/- 1.79) mg/l. The biological half-life was 1.4 hour. In urine, (41.2 +/- 7.7)% of the administered dose was eliminated within 8 hours on average.
