🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionOndansetron is well absorbed from the gastrointestinal tract after oral administration, with a bioavailability of approximately 60% due to first-pass metabolism.
DistributionIt is widely distributed in the body. Plasma protein binding is about 70-76%. It crosses the blood-brain barrier and placenta.
Protein BindingApproximately 70-76% bound to plasma proteins.
MetabolismOndansetron is extensively metabolized in the liver by multiple cytochrome P450 enzymes, including CYP3A4, CYP2D6, and CYP1A2.
Half-LifeThe elimination half-life is approximately 3-6 hours in adults. It may be prolonged in patients with severe hepatic impairment.
ExcretionMetabolites are excreted in urine and feces. Less than 5% of the dose is excreted unchanged in urine.
BioavailabilityAbout 60% after oral administration.
Onset of ActionOnset of action is within 30-60 minutes after oral administration.
Peak Plasma TimePeak plasma concentrations are reached approximately 1.5-2 hours after oral administration.
Duration of ActionThe antiemetic effect lasts for about 4-8 hours, depending on the dose and individual factors.

How It Works

Ondansetron is a selective 5-HT3 receptor antagonist. It works by blocking serotonin (5-hydroxytryptamine) at 5-HT3 receptors located on vagal nerve terminals in the gastrointestinal tract and in the central nervous system's chemoreceptor trigger zone. This blockade prevents serotonin from initiating the vomiting reflex, thereby reducing nausea and vomiting.

Mechanism Steps

1
Binding to 5-HT3 receptors: Ondansetron binds selectively to 5-HT3 receptors on vagal afferent nerves in the gut and in the chemoreceptor trigger zone of the brain.
2
Blockade of serotonin signaling: By occupying these receptors, it prevents serotonin released from enterochromaffin cells from activating the vomiting center.
3
Inhibition of vomiting reflex: This blockade interrupts the signal transmission to the vomiting center in the medulla, reducing the urge to vomit.
