A Randomized, Double-Blind, Crossover Study to Investigate the Pharmacokinetics of Extended-Release Melatonin Compared to Immediate-Release Melatonin in Healthy Adults.
Exogenous melatonin can be helpful for treatment of some sleep disorders. However, immediate-release formulations are rapidly absorbed and cleared from the body making it difficult to provide coverage for an entire sleep period. Extended-release melatonin formulations can better mimic the naturally occurring melatonin profile and increase efficacy, but few studies have reported on their pharmacokinetics. To assess the pharmacokinetics of extended-release melatonin, we conducted a randomized, double-blind, crossover study of extended-release melatonin (4 mg) compared to immediate-release melatonin (4 mg) in 18 healthy adults, ages 18-65 years. Participants received immediate-release or extended-release melatonin in clinic after an 8 h fast, and blood samples were taken over a 10-h period. After a 7-day washout period, the same procedures were repeated with the melatonin form not previously received. Extended-release melatonin had a longer time to peak concentration (1.56 vs 0.6 h) and elimination half-life (1.63 vs 0.95 h) compared with immediate-release melatonin. Maximum concentration was lower for extended-release melatonin compared with immediate-release melatonin (7581 pg/mL vs 13120 pg/mL). Extended-release melatonin raised melatonin levels in as little as 15 min and sustained elevated melatonin levels (>300 pg/mL) for 6 h before falling below 50 pg/mL by 9 h. No clinically relevant adverse events were observed, and safety parameters remained within normal ranges for both formulations. The pharmacokinetic profile of this extended-release melatonin formulation suggests that it could be used for future efficacy studies of melatonin and sleep outcomes. This trial is registered at ClinicalTrials.gov, NCT04067791.
期刊介绍:
The Journal of Dietary Supplements (formerly the Journal of Nutraceuticals, Functional & Medical Foods) has been retitled to reflect the bold departure from a traditional scientific journal presentation to a leading voice for anyone with a stake in dietary supplements. The journal addresses important issues that meet the broad range of interests from researchers, regulators, marketers, educators, and health professionals from academic, governmental, industry, healthcare, public health, and consumer education sectors. This vital tool not only presents scientific information but interprets it - helping you more readily pass it on to your students, patients, clients, or company.
