[Chemical Properties]

White Solid
[Uses]

Present in opium from 0.7% to 2.5%, depending on the source. Weak narcotic analgesic, perhaps due to conversion to morphine, with minimal hypnotic properties; potent antitussive. Controlled substance (opiate)
[Definition]

ChEBI: A morphinane alkaloid found in the opium poppy, Papaver somniferum var. album; has analgesic, anti-tussive and anti-diarrhoeal properties.
[General Description]

Colorless to white crystalline solid or white powder. Sublimes at 284°F. Odorless. Bitter taste. pH (saturated aqueous solution) 9.8.
[Air & Water Reactions]

CODEINE is light sensitive and sensitive to prolonged exposure to air. Insoluble in water.
[Reactivity Profile]

CODEINE is incompatible with bromides, iodides and salts of heavy metals. . CODEINE is an amine. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.
[Fire Hazard]

CODEINE is combustible.
[Hazard]

Habit-forming narcotic, sale legally restricted.
[Description]

Codein phosphate and hydrochloride caused contact dermatitis in a worker in the production of opium alkaloids. Codeine bitartrate caused contact dermatitis in a worker in the production of concentrated poppy straw. Codeine was a sensitizer in a laboratory worker at an opiate-manufacturing pharmaceutical company, also sensitive to the baine.
[Description]

Codeine (CRM) (Item No. ISO60140) is a certified reference material categorized as an opioid. Like other opioid analgesics, codeine is commonly abused. Codeine is regulated as a Schedule II compound in the United States. Codeine (CRM) (Item No. ISO60140) is provided as a DEA exempt preparation. This product is intended for research and forensic applications.

[World Health Organization (WHO)]

Codeine, which has antitussive, opioid analgesic and antidianhoeal activity, was first extracted from opium in 1832 and has since been widely used in medicine. The development of dependence and its potential for abuse resulted in the control af the substance under Schedule II of the 1961 Single Convention on Narcotic Drugs. Preparations containing codeine remain widely available and are included in the WHO Model List of Essential Drugs.(Reference: (WHTAC1) The Use of Essential Drugs, 2nd Report of the WHO Expert Committee, 722, , 1985)
[Biological Functions]

Like morphine, codeine is a naturally occurring opioid found in the poppy plant. Codeine is indicated for the treatment of mild to moderate pain and for its antitussive effects. It is widely used as an opioid antitussive because at antitussive doses it has few side effects and has excellent oral bioavailability. Codeine is metabolized in part to morphine, which is believed to account for its analgesic effect. It is one of the most commonly used opioids in combination with nonopioids for the relief of pain. The administration of 30 mg of codeine in combination with aspirin is equivalent in analgesic effect to the administration of 65 mg of codeine. The combination of the drugs has the advantage of reducing the amount of opioid required for pain relief and abolition of the pain via two distinct mechanisms, inhibition of prostanoid synthesis and opioid inhibition of nociceptive transmission. When given alone, orally administered codeine has about one-tenth to one-fifth the potency of morphine for the relief of pain. In addition, IV codeine has a greater tendency to release histamine and produce vasodilation and hypotension than does morphine. Thus, the use of IV codeine is rare. Codeine is rarely addictive and produces little euphoria.
[Health Hazard]

The toxic effects due to codeine are similarbut less toxic than those of morphineand other opium alkaloids. An overdosecan cause respiratory failure. It is a weakdepressant of the central nervous system.It also exhibits stimulant action. Toxicsymptoms from high dosages may includedrowsiness, sleep, tremors, excitement, andhallucinations. It may also produce gastricpains and constipation. An oral LD50 value in rats is 427 mg/kg. The habit-forming effectsof codeine are lower than those associatedwith morphine.
Nagamatsu and coworkers (1985) havereported in vitro formation of codeinonefrom codeine by rat or guinea pig liverhomogenate. Codeinone may be a metabolicintermediate in the presence of nicotinamideadenine dinucleotide (NAD). Its acute toxicityin mice was determined to be 30 timeshigher than that of codeine.
[Pharmacology]

Codeine is a constituent of opium. Up to 10% of a dose of codeine is metabolised by the hepatic microsomal enzyme CYP2D6 to morphine, which contributes significantly to its analgesic effect. The rest is metabolised in the liver to norcodeine and then conjugated to produce glucuronide conjugates of codeine, norcodeine and morphine. Codeine is considerably less potent than morphine. A round 8% of Western Europeans are deficient in the CYP2D6 enzyme and may not experience adequate analgesia with codeine. S imilarly, with super-metabolisers, there may be problems with opioid toxicity; particular care is needed in the breastfeeding mother as morphine is transferred in milk. Codeine can cause significant histamine release, and intravenous administration should be avoided. It has marked antitussive effects and also causes significant constipation. It is often combined with paracetamol.
[Purification Methods]

Codeine crystallises from water or aqueous EtOH. Dry it at 80o. Evaporation of a CHCl3 extract gives a colourless glass which crystallises on scratching. It crystallises from H2O as the monohydrate, m 157-158.5o, and has [] D -136o (c 2.8, EtOH). The hydrobromide crystallises in needles from H2O, and effervesces at 151-160o, solidifies and remelts with extensive decomposition at 273-278o. It sublimes at 100o/0.03mm.
