[Clinical trial of amoxycillin in chronic bronchitis and bronchial dilatations].

The therapeutic results were followed of amoxycilline after application in 57 cases of chronic bronchitis and bronchial dilatations that had been treated previously with antibiotics (including ampicillin--in 37 cases). The amount of amoxycilline was of 2 g per day, given in four 0,5 g doses. A total of 23,3 percent "very good" results were obtained (expectoration either disappeared completely or was reduced to 2--3 ml per day), and 40,4 percent "good" results (with expectoration down to less than one half of the initial amount). Thus in two-thirds of the cases the results were favourable. The cases that did not respond to ampicilline gave only 10,8 percent "very good" results but the "good" results represented 51,3 percent, indicating an increased efficiency of the new drug as compared with ampicilline. The serum levels of Amoxycilline (9,4 mg/ml after 2 hours, and 4,4 mg/ml after 4 hours), when a 0,5 g dose was given every 6 hours, assure a continuous and efficient bacteriostatic concentration. No significant adverse reaction were noted.
