It is the l-stereoisomer of methorphan. The effects of the two isomers are quite different. [[Dextromethorphan]] is an antitussive at low doses and a dissociative at much higher doses, whereas levomethorphan is an [[opioid]] analgesic. Levomethorphan has effects similar to levorphanol but is less potent as it must be demethylated to the active form by liver enzymes before becoming active.<br /> <br /> {{Analgesics}}<br /> {{Opioids}}<br /> [[Category:Drugs]]</div>
