Product Introduction

Bioactivity
Description
Palonosetron hydrochloride (RS 25259) is a 5-HT3 antagonist used in the prevention and treatment of chemotherapy-induced nausea and vomiting.
In vivo
Palonosetron exhibits a longer plasma half-life of approximately 40 hours compared to other antagonists in its class (ondansetron, 4 hours; tropisetron, 7.3 hours; dolasetron, 7.5 hours; ranisetron, 8.9 hours). Additionally, it demonstrates a hundredfold greater binding affinity to the 5-HT3 receptor, with a pKi of 10.5, which is significantly higher than that of granisetron (pKi 8.91), tropisetron (pKi 8.81), ondansetron (pKi 8.39), and dolasetron (pKi 7.6).

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
For Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
