Drug Metabolite Standards

A drug metabolite is a byproduct of the body breaking down, or “metabolizing” a drug into a different substance. Most drugs undergo chemical alteration by various bodily systems as a way to create compounds that are more easily excreted from the body. Drug metabolism can produce metabolites with physicochemical and pharmacological properties that differ substantially from those of the parent drug, and consequently have important implications for both drug safety and efficacy.
