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]
The WHO guidelines recommend prompt oral administration of drugs ("by the mouth") when pain occurs, starting, if the patient is not in severe pain, with non-opioid drugs such as paracetamol (acetaminophen) or aspirin, [1] with or without "adjuvants" such as non-steroidal anti-inflammatory drugs (NSAIDs) including COX-2 inhibitors.
Formulations containing 8 mg or less of codeine ("AC&C 8" or "222") are typically available from pharmacies over the counter. A prescription is not required, but the medication must be requested from the pharmacist. The "222" and higher numbers refer to the codeine narcotic content numbers as follows: 222 - contains 7.5 mg codeine
An analgesic adjuvant is a medication that is typically used for indications other than pain control but provides control of pain in some painful diseases. This is often part of multimodal analgesia, where one of the intentions is to minimize the need for opioids. [1] [2] [3]
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 ...
Nicocodeine is regulated in most cases as is codeine and similar weak opiate drugs like ethylmorphine, benzylmorphine, dihydrocodeine and its other close derivatives like acetyldihydrocodeine (although not the stronger hydrocodone or oxycodone, which are regulated like morphine) and others of this class in the laws of countries and the Single ...
Codeine without aspirin or acetaminophen (Tylenol) is very rarely available or prescribed to discourage abuse. Tablets of codeine in combination with aspirin or acetaminophen (paracetamol) and intended for pain relief are listed as Schedule III. Cough syrups are classed as Schedule III, IV, or V, depending on formulation.
In 1959, the combination of phenoperidine and haloperidol was first used in Europe in anesthesia to induce a detached, pain free state called neuroleptic analgesia; the use of that mixture boomed in early 1960s but was overtaken by the combination of fentanyl and droperidol, which was widely used through the 1980s. These combination approaches ...
