Origins, practices and future of safety pharmacology.
The origins of safety pharmacology are grounded upon observations that organ functions (like organ structures) can be toxicological targets in humans exposed to novel therapeutic agents, and that drug effects on organ functions (unlike organ structures) are not readily detected by standard toxicological testing. Safety pharmacology is " em leader those studies that investigate the potential undesirable pharmacodynamic effects of a substance on physiological functions in relationship to exposure in the therapeutic range and above em leader " [International Conference on Harmonization (ICH) S7A guidelines; Safety Pharmacology Studies for Human Pharmaceuticals]. This publication provides a comprehensive review of the history of safety pharmacology, international regulatory guidelines that govern the practices of this important field, and the scientific challenges that are being faced by its rapid emergence in pharmaceutical development. The criticality of identifying undesired adverse effects of new drugs in nonclinical models, which reflect the overall human condition, is reflected in the importance of generating an integrated and accurate assessment of possible human risk. The conundrum posed by the challenge of formulating a reliable risk assessment is the importance of improving and enhancing the safe progression of new drugs to the marketplace, while preventing unnecessary delays (or discontinuances), based on nonclinical findings that are not relevant or interpretable in terms of clinical response or human risk.
