Levorphanol (Levo-Dromoran®) is an dextromethorphan, and others. One morphinan derivative, cyclorphan was found to be highly hallucinogenic and psychotomimetic and have other untoward effects and of course was never marketed as an analgesic.

Levorphanol has the same properties as NMDA receptor antagonist.[2] Typical doses of levorphanol include 2 mg by mouth or subcutaneous injection every 6 to 8 hours.

Levorphanol has affinity to μ, κ, and δ ketobemidone, make levorphanol useful for types of pain that other analgesics may not be as effective against.

It is chemically related to dextromethorphan, an methyl ether dextrorotatory isomer of levorphanol.
