Chrono– Drug Delivery System– A Comprehensive Review
Year: 2025
Type: article
Abstract: Chrono-modulated drug delivery systems (CDDS) are innovative treatment systems that ensure peak performance with minimal side effects by coordinating drug release with the natural rhythms of the body. Diseases such as diabetes, cancer, hypertension, arthritis, asthma, and cardiovascular ailments that exhibit time-dependent symptomatology greatly benefit from CDDS. In order to dispense medications at optimal times, CDDS employs methodologies such as pulsatile, time-controlled, stimuli-responsive, multi-particulate, and implantable devices. To enhance outcomes and patient adherence, CDDS ensures that maximal drug concentration aligns with maximal disease activity through utilization of circadian fluctuations in pharmacokinetics and pharmacodynamics. Their effectiveness relies on materials such as temperature-responsive gels, pH-sensitive coatings, and biodegradable polymers. To ensure lag duration, release profile, and bioavailability, evaluation involves extensive in vitro, in vivo, and pharmacokinetic/pharmacodynamic analysis. Strong evidence of safety, efficacy, and reproducibility, supported by stability studies and in vitro–in vivo correlation, is demanded by regulatory bodies like the FDA and EMA. As wearable biosensors, personalized medicine, and chrono-pharmacology advance, CDDS offer a promising future for time-dependent, tailored treatment in preventive and chronic care.
