The effect is evident after 20–30 minutes after administration and persists for at least 4 hours. It acts primarily at the level of the CNS, but also shows a slight activity in inhibiting the bronchospasm. In such use, it is less effective than codeine and more effective than dextromethorphan in inhibiting the tussive stimulus.
