CLINICAL PHARMACOLOGY
DEXTROMETHORPHAN:
Dextromethorphan is an antitussive agent and, unlike the isomeric
levorphanol, it has no
analgesic or addictive properties.
The drug acts centrally and elevates the threshold for coughing. It is
about equal to
codeine in depressing the cough reflex. In therapeutic dosage
dextromethorphan does
not inhibit ciliary activity.
Dextromethorphan is rapidly absor
