🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionMelatonin is rapidly absorbed from the gastrointestinal tract after oral administration. However, it undergoes extensive first-pass metabolism, so bioavailability varies widely.
DistributionMelatonin is widely distributed throughout the body, including the brain. It crosses the blood-brain barrier and placenta. It is also found in saliva and breast milk.
Protein BindingApproximately 60% of melatonin is bound to plasma proteins.
MetabolismMelatonin is primarily metabolised in the liver by cytochrome P450 enzymes, mainly CYP1A2 and to a lesser extent CYP2C19. The main metabolite is 6-hydroxymelatonin.
Half-LifeThe elimination half-life of melatonin is short, typically 30 to 50 minutes. However, the effects on sleep may last longer.
ExcretionMelatonin and its metabolites are excreted mainly in the urine as sulfate and glucuronide conjugates. About 80% is excreted in urine.
BioavailabilityOral bioavailability of melatonin is low and variable, estimated between 3% and 15% due to first-pass metabolism.
Onset of ActionThis medicine typically starts working within 30 to 60 minutes after oral administration.
Peak Plasma TimePeak plasma concentrations are usually reached within 60 minutes after oral intake.
Duration of ActionThe sleep-promoting effects usually last for about 4 to 6 hours, but this can vary.

How It Works

Melatonin is a hormone that binds to melatonin receptors MT1 and MT2 in the brain. By activating these receptors, it helps synchronise the body's internal clock and promotes sleepiness. It does not act as a central nervous system depressant like traditional sleeping pills.

Mechanism Steps

1
Binding to melatonin receptors: After absorption, melatonin binds to MT1 and MT2 receptors in the suprachiasmatic nucleus of the brain.
2
Inhibition of wake-promoting signals: Activation of MT1 receptors reduces neuronal firing in the wake-promoting areas of the brain.
3
Phase shifting of circadian rhythm: MT2 receptor activation helps shift the timing of the internal body clock, making it easier to fall asleep at the desired time.
4
Promotion of sleep: The overall effect is a reduction in sleep latency and an increase in sleep duration without altering normal sleep architecture.
