GlossaryIn Vitro Release

measuring drug release from formulations in a lab setting

In Vitro Release (IVR) refers to the process of measuring how a drug is released from a formulation (like a cream, gel, or tablet) into a controlled environment outside of a living organism, typically in a laboratory setting. This method helps researchers understand the rate and extent of drug release, which is crucial for predicting how the drug will behave in the human body.
