Identification
- Summary
Tropisetron is a 5HT-3 receptor antagonist used as an antiemetic in the treatment of chemotherapy-induced nausea and vomiting.
- Generic Name
- Tropisetron
- DrugBank Accession Number
- DB11699
- Background
Tropisetron is an indole derivative with antiemetic activity. As a selective serotonin receptor antagonist, tropisetron competitively blocks the action of serotonin at 5HT3 receptors, resulting in suppression of chemotherapy- and radiotherapy-induced nausea and vomiting.
Tropisetron appears to be well tolerated with the most frequently reported adverse effect being headache. Extrapyramidal side effects are rare upon using tropisetron.

- Pharmacodynamics
Not Available
- Mechanism of action
Tropisetron competitively binds to and blocks the action of serotonin at 5HT3 receptors peripherally on vagus nerve terminals located in the gastrointestinal (GI) tract as well as centrally in the chemoreceptor trigger zone (CTZ) of the area postrema of the central nervous system (CNS). This results in the suppression of chemotherapy- and radiotherapy-induced nausea and vomiting.
Target Actions Organism A5-hydroxytryptamine receptor 3A antagonistHumans - Absorption
The absorption of tropisetron from the gastrointestinal tract is rapid (mean half-life of about 20 minutes) and nearly complete (more than 95%). Due to first-pass metabolism in the liver, the absolute bioavailability of a 5 mg oral dose is 60%. The peak plasma concentration is attained within three hours.
- Volume of distribution
400-600 L.
- Protein binding
71% bound to plasma protein in a non-specific manner.
- Metabolism
The metabolism of tropisetron occurs by hydroxylation at the 5, 6 or 7 positions of its indole ring, followed by a conjugation reaction to the glucuronide or sulphate with excretion in the urine or bile (urine to faeces ratio 5:1). The metabolites have a greatly reduced potency for the 5-HT3 receptor and do not contribute to the pharmacological action of the drug.
- Route of elimination
About 8% of tropisetron is excreted in the urine as unchanged drug, 70% as metabolites; 15% is excreted in the feces.
- Half-life
5.7 h.
- Clearance
1800 ml/min.

Drug Interaction Integrate drug-drug
interactions in your software1,2-Benzodiazepine The risk or severity of CNS depression can be increased when Tropisetron is combined with 1,2-Benzodiazepine. Abacavir Abacavir may decrease the excretion rate of Tropisetron which could result in a higher serum level. Acebutolol Acebutolol may increase the arrhythmogenic activities of Tropisetron. Aceclofenac Aceclofenac may decrease the excretion rate of Tropisetron which could result in a higher serum level. Acemetacin Acemetacin may decrease the excretion rate of Tropisetron which could result in a higher serum level. - Food Interactions
