Racemorphan, or morphanol, is the racemic mixture of the two stereoisomers of 17-methylmorphinan-3-ol, each with differing pharmacology and effects:
Dextrorphan - an antitussive and dissociative hallucinogen (NMDA receptor antagonist)
Levorphanol - an opioid analgesic
Racemorphan itself is under international control per the Single Convention on Narcotic Drugs 1961 and is therefore listed as a Schedule II Narcotic controlled substance in the US Controlled Substances Act 1970; it has an ACSCN of 9733 and in 2014 it had an aggregate annual manufacturing quota of zero. The salts in use are hydrobromide (free base conversion ratio 0.741), hydrochloride (0.876), and tartrate (0.632).

Levorphanol (brand name Levo-Dromoran) is an opioid medication used to treat moderate to severe pain. It is the levorotatory enantiomer of the compound racemorphan. Its dextrorotatory counterpart is dextrorphan. It was first described in Germany in 1946. The drug has been in medical use in the United States since 1953. Levorphanol acts predominantly as an agonist of the μ-opioid receptor (MOR), but is also an agonist of the δ-opioid receptor (DOR), κ-opioid receptor (KOR), and the nociceptin receptor (NOP), as well as an NMDA receptor antagonist and a serotonin-norepinephrine reuptake inhibitor (SNRI).
La noscapine est la dénomination commune internationale de la L-narcotine. C'est un alcaloïde dont les propriétés sont proches de celles de la codéïne et de la morphine. Son nom narcotine provient du mot grec signifiant assoupissements : narkê. Elle a été découverte en 1803 par Jean-François Derosne. Elle se présente sous la forme d'un solide cristallisé, blanc, de saveur amère. Utilisée comme un antitussif non narcotique elle peut néanmoins provoquer des vertiges, somnolences, troubles gastro-intestinaux, une certaine excitation-confusion ainsi qu'une dépression respiratoire en cas de surdosage.
