Some patients request to be switched to a different narcotic due to stigma associated with a particular drug (e.g. a patient refusing methadone due to its association with opioid addiction treatment). [4] Equianalgesic charts are also used when calculating an equivalent dosage of the same drug, but with a different route of administration.
Opioid dose conversions may be necessary when switching medications given the differing pharmacodynamics between opioids. Generally, parenteral (IV or IM) morphine is used as the standard for converting between opiates to achieve equivalent analgesic effects.
Oral hydrocodone has a mean equivalent daily dosage (MEDD) factor of 0.4, meaning that 1 mg of hydrocodone is equivalent to 0.4 mg of intravenous morphine. However, because of morphine's low oral bioavailability, there is a 1:1 correspondence between orally administered morphine and orally administered hydrocodone. [56]

The choice of what opioid drug to use in which patient thus tends to be a balance between many different factors that must be considered, and the need for opioid rotation in chronic pain patients makes it advantageous for a wide range of different opioid drugs to be available, even though they may be broadly equivalent in action when used in ...
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.
