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.
Regulations state the pharmacists may, without a prescription, sell low-dose codeine products (containing up to 8 mg of codeine per tablet or up to 20 mg per 30 ml in liquid preparation) if the preparation contains at least two additional medicinal ingredients other than a narcotic (S.36.1 NCR).
So when I go to the page for Tylenol, it states that Tylenol 1 contains 8 mg codeine, 2 contains 15 mg, 3 contains 30 mg, 4 contains 60 mg (all of which, so far, I know first-hand to be correct) and finally, that Tylenol 5 contains 90 mg of codeine. However, this page states that they only go up to Tylenol 4 and that 60 mg is the maximum dosage ...
An equianalgesic chart is a conversion chart that lists equivalent doses of analgesics (drugs used to relieve pain). Equianalgesic charts are used for calculation of an equivalent dose (a dose which would offer an equal amount of analgesia) between different analgesics. [1]
Threshold dose is the minimum dose of drug that triggers minimal detectable biological effect in an animal. [1] At extremely low doses, biological responses are absent for some of the drugs. The increase in dose above threshold dose induces an increase in the percentage of biological responses. [ 2 ]
The recommended maximum daily dose for an adult is three to four grams. [27] [39] Higher doses may lead to toxicity, including liver failure. [40] Paracetamol poisoning is the foremost cause of acute liver failure in the Western world, and accounts for most drug overdoses in the United States, the United Kingdom, Australia, and New Zealand. [41 ...
10 mg dihydrocodeine as co-dydramol 10/500, this is also the preparation to be dispensed if no strength is specified on a prescription. 20 mg dihydrocodeine as co-dydramol 20/500 (e.g. branded products Paracod 500/20 and Remedeine). 30 mg dihydrocodeine as co-dydramol 30/500 (e.g. branded products Paracod 500/30 and Remedeine Forte).
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 ...
