[Pharmacokinetics of protegentin, a combined preparation].
Protegentin is a combined preparation in the form of ointment containing 0.1 per cent of gentamicin, 0.25 per cent of erythromycin and 0.1 per cent of protease C. Pharmacokinetic studies on the preparation were conducted. Protegentin and gentamicin ointment, currently manufactured in this country, were applied to the surface of experimental pure cutaneous wounds in guinea pigs in a dose of 1 g. It was shown that inspite of the same contents of gentamicin in the ointments, the mean maximum concentration of the antibiotic in the underlying muscular tissue after the protegentin application was somewhat higher than that after the use of the gentamicin ointment. The differences in the drug concentration maintained during the whole observation period of 24 hours. However, they were not statistically significant. The gentamicin concentrations in serum after the use of protegentin were also somewhat higher than those after application of the gentamicin ointment (the differences were not statistically significant). Still, in no case the concentrations reached the potentially toxic ones. The erythromycin concentrations in the muscular tissue were much higher than those in the blood.
