WebGlucuronidation is the main metabolic pathway, but the principal metabolite, morphine-3-glucuronide (M3G), is inactive. Morphine-6-glucuronide (M6G) is produced in smaller amounts than M3G, but is pharmacologically active and many times more potent than M. Webdrugs are called prodrugs, they have no intrinsic activity before metabolism; examples include diamorphine, codeine, enalapril and levodopa. Some drug metabolites have significant activity similar to the parent compound e.g. diazepam and its metabolite desmethyldiazepam. ATOTW 179 The role of the liver in drug metabolism 17/05/2010 …

"When taken orally, heroin undergoes extensive first-pass metabolism via deacetylation, making it a prodrug for the systemic delivery of morphine. When the drug is injected, however, it avoids this first-pass effect, very rapidly crossing the blood–brain barrier because of the presence of the acetyl groups, which render it much more fat soluble than morphine itself. Once in the brain, it then i… " - Diamorphine metabolism
