🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionGranisetron is rapidly and well absorbed from the gastrointestinal tract after oral administration. The absolute bioavailability of the oral tablet is approximately 60% in healthy subjects, but it may be higher in cancer patients. Food does not significantly affect the absorption of granisetron.
DistributionGranisetron is widely distributed throughout the body. It has a volume of distribution of approximately 3 L/kg. It crosses the blood-brain barrier and is found in breast milk.
Protein BindingGranisetron is approximately 65% bound to plasma proteins.
MetabolismGranisetron is extensively metabolized in the liver, primarily by cytochrome P450 enzymes, specifically CYP3A4. The main metabolites are 7-hydroxygranisetron and 9-desmethylgranisetron, which have little or no pharmacological activity.
Half-LifeThe elimination half-life of granisetron is approximately 3 to 6 hours in healthy adults, but it may be prolonged in patients with hepatic impairment.
ExcretionGranisetron is excreted primarily in the urine (approximately 48% as metabolites and 12% unchanged) and in the feces (approximately 34% as metabolites).
BioavailabilityThe oral bioavailability of granisetron is approximately 60% in healthy subjects, but it may be higher in cancer patients.
Onset of ActionThe antiemetic effect of oral granisetron begins within 30 to 60 minutes after administration.
Peak Plasma TimePeak plasma concentrations of granisetron are reached approximately 1 to 2 hours after oral administration.
Duration of ActionThe antiemetic effect of a single oral dose of granisetron lasts up to 24 hours, but it is often dosed once daily for chemotherapy-induced nausea and vomiting.

How It Works

Granisetron is a selective 5-hydroxytryptamine3 (5-HT3) receptor antagonist. It works by blocking serotonin (5-HT) from binding to 5-HT3 receptors located on vagal afferent nerve terminals in the gastrointestinal tract and in the chemoreceptor trigger zone of the central nervous system. This blockade prevents the emetic signals that trigger nausea and vomiting. Granisetron has little or no affinity for other serotonin receptors, dopamine receptors, or other neurotransmitter receptors, which contributes to its specific antiemetic effect.

Mechanism Steps

1
Binding to 5-HT3 receptors: Granisetron selectively binds to 5-HT3 receptors on vagal afferent nerves in the gut and in the brain's chemoreceptor trigger zone.
2
Blockade of serotonin signaling: By occupying these receptors, it prevents serotonin released from enterochromaffin cells (due to chemotherapy or radiation) from activating the vomiting reflex.
3
Inhibition of emetic pathways: This blockade interrupts signals to the vomiting center in the brain, thereby preventing nausea and vomiting.
