WebMetabolism [ edit] Remifentanil is considered a metabolic soft drug, [13] one that is rapidly metabolized to an inactive form. Unlike other synthetic opioids which are hepatically metabolized, remifentanil has an ester linkage which undergoes rapid hydrolysis by non-specific tissue and plasma esterases. WebThe opioids most commonly employed are diamorphine (UK), morphine (US), or more recently hydromorphone. The avoidance of first-pass metabolism increases bioavailability, although there is some variation in practice as to actual dosage regimens.
