Bioavailability Mechanics

Meaning

The comprehensive study and application of the physiological and biochemical processes that determine the rate and extent to which an administered substance is absorbed and becomes available at its intended site of action. This clinical focus ensures that hormones, nutrients, or pharmaceutical agents are delivered effectively to target tissues. Understanding bioavailability mechanics is critical for maximizing therapeutic efficacy and minimizing waste or adverse effects. It quantifies the fraction of an administered dose that reaches the systemic circulation unchanged.
