The effect of the preparation Duopect (narcotine hydrochloride + glyceryl guiacolate) on intensity and frequency of cough and expectoration was evaluated by the preferential test in 62 patients with chronic bronchitis. The preparation was compared to narcotine and to a placebo in a double-blind study. Duopect was found to be an effective antitussive and expectorant medicine with only minimal and transient side effects.
