Physiological Accessibility

Meaning

Physiological Accessibility is a clinical term describing the ease and efficiency with which an administered therapeutic agent, nutrient, or endogenous signaling molecule can reach its intended target tissue and elicit a biological response. This concept encompasses pharmacokinetics—absorption, distribution, metabolism, and excretion—and pharmacodynamics, including receptor density and sensitivity. High accessibility is a prerequisite for maximum therapeutic efficacy and biological effect.
