usually biotransformation results in a more water soluble, more readily excreted form of the parent drug. In most cases this inactivates the drug, but there are some exceptions which involve the formation of metabolites with activity (diazepam) or when an inactive prodrug is given (levodopa) which becomes active after the first step in the
biotransformation pathway (DOPA) sometimes are asked in questions of this form.
