Pharmacology
Indication

For treatment and management of pain (systemic). It is also used as an antidiarrheal and as a cough suppressant.

Structured Indications
Pharmacodynamics

Codeine, an opiate agonist in the CNS, is similar to other phenanthrene derivatives such as morphine. It is selective for the mu receptor, but with a much weaker affinity than morphine. The analgesic properties of codeine have been speculated to come from its conversion to morphine. The principle therapeutic action is analgesia. Codeine concentrations do not correlate with brain concentration or relief of pain. The minimum effective concentration is highly variable is influenced by numerous factors, including but not limited to, age, previous opioid use, age, and general medical condition. However, the effective dose for patients that have developed tolerance is significantly higher than the opioid-naive patients.

Mechanism of action

Opiate receptors are coupled with G-protein receptors and function as both positive and negative regulators of synaptic transmission via G-proteins that activate effector proteins. Binding of the opiate stimulates the exchange of GTP for GDP on the G-protein complex. As the effector system is adenylate cyclase and cAMP located at the inner surface of the plasma membrane, opioids decrease intracellular cAMP by inhibiting adenylate cyclase. Subsequently, the release of nociceptive neurotransmitters such as substance P, GABA, dopamine, acetylcholine and noradrenaline is inhibited. Opioids also inhibit the release of vasopressin, somatostatin, insulin and glucagon. Codeine's analgesic activity is, most likely, due to its conversion to morphine. Opioids close N-type voltage-operated calcium channels (OP2-receptor agonist) and open calcium-dependent inwardly rectifying potassium channels (OP3 and OP1 receptor agonist). This results in hyperpolarization and reduced neuronal excitability.

Absorption

Well absorbed following oral administration with a bioavailability of approximately 90%. Maximum plasma concentration occurs 60 minutes post-administration. Food does not effect the rate or extent of absorption of codeine.

Volume of distribution

Apparent volume of distribution = 3-6 L/kg

Protein binding

7-25% bound to plasma proteins.

Metabolism

Hepatic. Codeine is a prodrug, itself inactive, but demethylated to the active morphine by the liver enzyme CYP2D6 to morphine. 70-80% of the dose undergoes glucuronidation to form codeine-6-glucuronide. This process is mediated by UDP-glucuronosyltransferase UGT2B7 and UGT2B4. 5-10% of the dose undergoes O-demethylation to morphine and 10% undergoes N-demethylation to form norcodeine. CYP2D6 mediates the biotransformation to morphine. CYP3A4 is the enzymes that mediates the conversion to norcodiene. Morphine and norcodeine are further metabolized and undergo glucuronidation. The glucuronide metabolites of morphine are morphine-3-glucuronide (M3G) and morphine-6-glucuronide (M6G). Both morphine and morphine-6-glucuronide are active and have analgesic activity. Norcodiene and M3G do not have any analgesic properties.

Specific Function:
Receptor for endogenous opioids such as beta-endorphin and endomorphin. Receptor for natural and synthetic opioids including morphine, heroin, DAMGO, fentanyl, etorphine, buprenorphin and methadone. Agonist binding to the receptor induces coupling to an inactive GDP-bound heterotrimeric G-protein complex and subsequent exchange of GDP for GTP in the G-protein alpha subunit leading to dissociati...
