title: Chronopharmaceutical drug delivery systems: Hurdles, hype or hope?
abstract: The current advances in chronobiology and the knowledge gained from chronotherapy of selected diseases strongly suggest that "the one size fits all at all times" approach to drug delivery is no longer substantiated, at least for selected bioactive agents and disease therapy or prevention. Thus, there is a critical and urgent need for chronopharmaceutical research (e.g., design and evaluation of robust, spatially and temporally controlled drug delivery systems that would be clinically intended for chronotherapy by different routes of administration). This review provides a brief overview of current drug delivery system intended for chronotherapy. In theory, such an ideal "magic pill" preferably with affordable cost, would improve the safety, efficacy and patient compliance of old and new drugs. However, currently, there are three major hurdles for the successful transition of such system from laboratory to patient bedside. These include the challenges to identify adequate (i) rhythmic biomaterials and systems, (ii) rhythm engineering and modeling, perhaps using system biology and (iii) regulatory guidance.
