WebAlthough diamorphine has a lower lipid solubility compared with fentanyl, there is a higher proportion of unionized drug available for diffusion to receptor sites which is metabolized to active analgesic with a relatively long duration of action. WebPhase 1 metabolism of opioids mainly involves the CYP3A4 and CYP2D6 enzymes. The CYP3A4 enzyme metabolizes more than 50% of all drugs; consequently, opioids …
WebParacetamol is extensively metabolised (predominantly in the liver), the major metabolites being the sulphate and glucuronide conjugates. A minor fraction of drug is converted to a highly reactive alkylating metabolite which is inactivated with reduced glutathione and excreted in the urine as cysteine and mercapturic acid conjugates.
