DEXTROMETHORPHAN

also called d-3-methoxy-n-methylmorphinan synthetic drug related to morphine and used in medicine as a cough suppressant. The hydrobromide salt of dextromethorphan is administered orally in syrups and tablets. It acts upon the central nervous system to suppress the cough reflex. It does not produce addiction or central depression, as do a number of other morphine derivatives, and it has no analgesic effect. Dextromethorphan hydrobromide occurs as white crystals or a white crystalline powder, soluble in water, alcohol, and chloroform.
