Dolasetron-d4 is intended for use as an internal standard for the quantification of dolasetron by GC- or LC-MS. Dolasetron is an antagonist of the serotonin (5-HT) receptor subtype 5-HT3 (Ki = 20 nM). It is selective for 5-HT3 receptors over 5-HT1A, 5-HT1B, 5-HT2, dopamine D2, α1-, α2-, and β-adrenergic, M1-5 muscarinic acetylcholine, and neurokinin-1 (NK1) receptors (IC50s = >10 µM for all). Dolasetron inhibits 5-HT-induced membrane currents in NG 108-15 cells (IC50 = 3.8 nM). It increases the latency to emesis and reduces the number of vomiting and retching episodes induced by cisplatin in ferrets when administered at doses of 0.5 or 2 mg/kg. Formulations containing dolasetron have been used in the prevention of postoperative or chemotherapy-induced nausea.
