Codeine/paracetamol, also called codeine/acetaminophen and co-codamol, is a compound analgesic, comprising codeine phosphate and paracetamol (acetaminophen). Codeine/paracetamol is used for the relief of mild to moderate pain when paracetamol or non-steroidal anti-inflammatory drugs (NSAIDs; such as ibuprofen, aspirin, and naproxen) alone do not sufficiently relieve symptoms.
Codeine is marketed as both a single-ingredient drug and in combination preparations with paracetamol (as co-codamol: e.g., brands Paracod, Panadeine, and the Tylenol-with-codeine series, including Tylenol 3 and 1, 2, and 4); with aspirin (as co-codaprin); or with ibuprofen (as Nurofen Plus).

Paracetamol's bioavailability is dose-dependent: it increases from 63 % for 500 mg dose to 89 % for 1000 mg dose. [6] Its plasma terminal elimination half-life is 1.9–2.5 hours, [ 6 ] and volume of distribution is roughly 50 L. [ 132 ] Protein binding is negligible, except under the conditions of overdose, when it may reach 15–21 %. [ 6 ]
Approved indication for dihydrocodeine is the management of moderate to moderately severe pain as well as coughing and shortness of breath. As is the case with other drugs in this group, the antitussive dose tends to be less than the analgesic dose, and dihydrocodeine is a powerful cough suppressant like all other members of the immediate codeine family (see below) and their cousins ...
Co-dydramol is a non-proprietary name used to denote a particular compound analgesic, a combination of dihydrocodeine tartrate and paracetamol. Co-dydramol tablets are used for the relief of moderate pain. Co-dydramol is part of a series of combination drugs available in the UK and other countries including co-codaprin (aspirin and codeine).
[20] 85% of the oral dose is excreted via the kidneys. [2] At high doses, the supply of glutathione cannot meet its demand, thus resulting in the accumulation of highly reactive compounds leading to liver damage.
The median effective dose is the dose that produces a quantal effect (all or nothing) in 50% of the population that takes it (median referring to the 50% population base). [6] It is also sometimes abbreviated as the ED 50, meaning "effective dose for 50% of the population". The ED50 is commonly used as a measure of the reasonable expectancy of ...
