🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionThis medicine is given by injection, so absorption is not applicable. It is directly introduced into the bloodstream or muscle tissue.
DistributionAfter injection, this medicine distributes widely into body tissues and fluids. It crosses the blood-brain barrier to reach the chemoreceptor trigger zone. Protein binding is moderate, approximately 70-76%.
Protein BindingApproximately 70-76% bound to plasma proteins.
MetabolismThis medicine is extensively metabolized in the liver by multiple cytochrome P450 enzymes, including CYP3A4, CYP2D6, and CYP1A2. The metabolites are largely inactive.
Half-LifeThe elimination half-life is approximately 3 to 6 hours in healthy adults. It may be prolonged in patients with severe liver impairment.
ExcretionThis medicine and its metabolites are excreted primarily in the urine (about 60%) and feces (about 40%).
BioavailabilityBioavailability is not applicable for intravenous administration. For intramuscular injection, bioavailability is approximately 90-100%.
Onset of ActionNausea and vomiting relief usually begins within 30 minutes after intravenous administration and within 10-20 minutes after intramuscular injection.
Peak Plasma TimePeak plasma concentration is reached at the end of an intravenous infusion or within 10-20 minutes after intramuscular injection.
Duration of ActionThe antiemetic effect typically lasts 4 to 8 hours after a single intravenous dose, and up to 12 hours after intramuscular administration.

How It Works

This medicine works by selectively blocking serotonin 5-HT3 receptors located on vagal nerve terminals in the gastrointestinal tract and in the chemoreceptor trigger zone of the brain. By blocking these receptors, it prevents serotonin from triggering the vomiting reflex. This action is most effective against nausea and vomiting caused by chemotherapy, radiation, and surgery, which release large amounts of serotonin.

Mechanism Steps

1
Selective 5-HT3 receptor blockade: This medicine binds to serotonin 5-HT3 receptors on vagal afferent nerves in the gastrointestinal tract and in the chemoreceptor trigger zone of the brain.
2
Inhibition of serotonin signaling: By blocking these receptors, it prevents serotonin released from enterochromaffin cells from activating the vomiting center.
3
Suppression of vomiting reflex: The blockade reduces the signals that travel to the vomiting center in the medulla, thereby preventing nausea and vomiting.
4
Rapid onset after injection: When given intravenously or intramuscularly, this medicine reaches effective blood levels quickly, making it useful for acute nausea and vomiting.
