levomethorphan การใช้

At the current time, no levomethorphan pharmaceuticals are marketed in the United States.
Levomethorphan is listed under the Single Convention on Narcotic Drugs 1961 and is regulated like morphine in most countries.
"' Levomethorphan "'( BAN ) is an opioid analgesic of the morphinan family that has never been marketed.
Levomethorphan is a prodrug to levorphanol, analogously to DXM acting as a prodrug to dextrorphan or codeine behaving as a prodrug to morphine.
As such, levomethorphan has similar effects to levorphanol but is less potent as it must be demethylated to the active form by liver enzymes before being able to produce its effects.
