title: Azidocillin levels in tracheobronchial secretions.
abstract: Concentrations of azidocillin in serum and tracheobronchial secretions were followed in 20 patients after an oral dose of 0.75 g of the drug. Serum concentrations were followed for 4 h and the concentration in tracheobronchial secretion was determined in samples taken through a fibreoptic bronchoscope 1--2 h after administration. The concentration in secretions varied between hardly measurable levels and 1.1 micrograms/ml. No correlation between levels in serum and tracheobronchial secretion was found. A slight tendency to higher secretion levels was found when the bronchoscopy showed signs of tracheobronchitis.
