Detailed explanation-1: -Opiates (e.g., morphine, codeine, and thebaine) exert their main effects on the brain and spinal cord. Their principal action is to relieve or suppress pain. The drugs also alleviate anxiety; induce relaxation, drowsiness, and sedation; and may impart a state of euphoria or other enhanced mood.
Detailed explanation-2: -Codeine is a morphine derivative with less analgesic and sedative effects than morphine. Codeine is metabolized to morphine by the cytochrome P450 enzyme (CYP) 2D6. Inhibitors of this enzyme (such as fluoxetine and citalopram) can decrease or even abolish the effect of codeine.
Detailed explanation-3: -Morphine and codeine are naturally occurring alkaloids in opioid plants, have long been used as a drug, and are also abused.
