[Pharmakokinetic and clinical studies with azlocillin in paediatrics (author's transl)].

Abstract

Azlocillin, an acylureido penicillin with bactericidal activity, is particularly effective against Pseudomonas, enterococci and Haemophilus influenzae. It is also very active against E. coli, various Proteus species and Bacteroides. Pharmacokinetic studies were carried out in 138 children of various ages (prematures, newborns, infants, schoolchildren) after administering 50-75-100 mg/kg/ body weight azlocillin via the i.v. or i.m. routes; The constant of elimination and the distribution volumes were calculated besides the serum levels. In prematures and newborns, therapeutically effective serum levels were obtained on administering 50 or 100 mg/kg body weight twice daily. Infants and older children required 100 or 75 mg/kg body weight t.i.d. Determination of azlocillin in the bronchial secretion after i.v. doses of 75 mg/kg body weight showed good elimination. Azlocillin was always identified up to the 5th hour post injectionem. Inspite of parenteral administration, azlocillin was identified in different concentrations in the meconium as well. 39 children were treated with azlocillin, 35 of whom had Pseudomonas infection. Very good results were obtained in infections of the urinary tract, wound infections, conjunctivitis, dacryocystitis and in one case of meningitis. Bronchopulmonary diseases did not take an equally good course, but in these cases the conditions had not been favourable. No serious side effects were revealed by testing several laboratory parameters.
