Melatonin

For an informed discussion with your doctor or pharmacist. This information collection is not a clinically validated interaction checker. Missing data do not establish safety. Do not change or stop prescribed medicines on the basis of this information. The findings apply to the specific conditions studied; laboratory and animal studies cannot be directly extrapolated to humans.

Active substance: Melatonin

Examples of brand names: Circadin [EU/DE]

ATC code: N05CH01

Main use (for orientation): Sleep disorders

Documented research summary

Direct preclinical CBN/CBD–melatonin pharmacokinetic interactions with species, dose and route differences. Subjective-sleep product trial is not a pharmacokinetic assessment and shows no clear combination superiority. THC conference data: small combination cohort with external pharmacokinetic comparison data. Tumour/reproductive models do not support treatment recommendations.

Uncertainties and limitations

Shared enzymes must not be equated with clinical evidence of an interaction; CBD/THC findings cannot be extrapolated to other cannabinoids.

CBN mouse AUC and CBD human-model factors are not measured human pair factors.

16805813: endogenous biosynthesis; the substance abbreviated THC is 9-carboxy-11-nor-Delta9-THC, not Delta9-THC.
