Product Introduction

Bioactivity
Description
DL-Laudanosine (Laudanosine) is a recognized metabolite of atracurium and cisatracurium.
In vivo
laudanosine, a metabolite of atracurium and a central nervous system stimulant, might increase the minimum alveolar concentration (MAC) of halothane.?These estimates were used to determine the rates of infusion that would produce steady state plasma concentrations of laudanosine of approximately 200, 400, and 800 ng .?ml-1.?Subsequent infusion of laudanosine in eight rabbits produced mean (+/- SD) steady state plasma concentrations of laudanosine of 234 +/- 56, 457 +/- 66, and 873 +/- 105 ng .?ml-1.?The control value for MAC of halothane was 1.08 +/- 0.28%.?At the lowest steady state plasma laudanosine concentration, MAC did not significantly differ from control (MAC = 1.15 +/- 0.23%, P less than 0.1).?However, at 457 and 873 ng .?ml-1, laudanosine significantly increased the MAC of halothane by 23% and 30%, respectively.?Infusion with saline in two additional rabbits did not affect MAC. Therefore, at the plasma concentrations of laudanosine found in humans after administration of atracurium, laudanosine increased the MAC of halothane in rabbits[1].

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.
