Why Science? | ICH S7A Safety Pharmacology and Vital Organ Functions

Safety pharmacology studies investigate effects on physiological functions in relation to exposure. They complement general toxicology and differ from primary pharmacology, which asks whether the intended target produces the desired effect.
