Efficacy and Tolerability of Levodropropizine in Adult Patients with Non-productive Cough. Comparison with Dextromethorphan
The results of a double-blind, randomized clinical trial involving 209 adult patients of either sex with moderate non-productive cough are reported. The therapeutic efficacy and the tolerability of levodropropizine syrup (60 mg t.i.d. for 5 days) was evaluated in comparison with dextromethorphan syrup (15 mg t.i.d. for 5 days). Efficacy was assessed by the number of coughing spells in a 6 h period, the cough frequency classes, the cough intensity and the night awakenings due to cough. Tolerability was evaluated by laboratory results, vital signs and any adverse event occurred during the clinical trial, including presence or absence of somnolence.
