(A multicentre clinical trial) The authors treated 120 patients showing the symptoms of chronic bronchitis with BV or placebo for 6 months during the winter period of 1992-93 in a multicentre double-blind clinical trial. The status of the patients was evaluated monthly and the data were analyzed at an independent computer company. The clinical symptoms were significantly milder in the BV group as compared with the placebo group and antibiotics consumption in the BV group was almost half of that recorded in the placebo group. These findings confirm that BV can be effective in the prophylaxis of the exacerbation of chronic bronchitis.
