Popis: In a recent series of unprecedented collaborative meetings between U.S. FDA members of the controlled substances staff (CSS) within the center for drug evaluation and research (CDER) and the pharmaceutical industry (pharmaceutical research and manufacturers association–PhRMA) members have delineated a “standard” for conducting preclinical abuse liability screening of all new molecular entities that affect the CNS. We argue for a “mind shift” in policies and methodologies used to quantify the potential discontinuation syndrome that may be engendered following abrupt cessation of repeated dose administrations of all New Molecular Entities under this new model. We argue against the use of the current “fixed dose” strategy to the more informative “escalating dose” or “equivalent dose” strategies that more accurately predicts the dependence potential of drug substances regardless of expected therapeutic doses.
