[Pediatric pharmacology of azlocilin (author's transl)].

Pharmacokinetic investigations of acylureido-penicillins azlocillin in newborns, infants and school shildren showed age dependend results. The differences were especially evident in a prolongation of the serum half-life to 2,56 hours in newborns compared to 0.94 hours in school children. On the basis of our pharmacokinetic results and of the dosages resulting from the data the antibiotic was used clinically in twenty eight patients with Pseudomonas aeruginosa infections and one patient with a Proteus mirabilis infection. The results were much better in infections of the urinary tract than in infections of the respiratory tract. This might be due to an observe bacterial presistence in spite of highly effective levels of azlocillin in bronchial secretion. The tolerance to the antibiotic was good.
