In vitro

Desvenlafaxine is a serotonin-norepinephrine reuptake inhibitor and is the active metabolite of the antidepressant venlafaxine. Similar to venlafaxine, desvenlafaxine inhibits the neuronal uptake of serotonin and norepinephrine. Desvenlafaxine shows weak binding affinity (62% inhibition at 100 μM) at the human dopamine (DA) transporter. Desvenlafaxine inhibits [3H]5-HT or [3H]NE uptake for the hSERT or hNET with IC50 of 47.3 and 531.3 nM, respectively.[1] Desvenlafaxine has the potential to inhibit CYP2D6, which could result in increased concentrations of drugs metabolized through this pathway. Induction of CYP3A4 is also possible with desvenlafaxine, which could impact the metabolism of drugs metabolized via this enzyme. [2]

In vivo Desvenlafaxine rapidly penetrates the male rat brain and hypothalamus. Desvenlafaxine significantly increases extracellular NE levels compared with baseline in the male rat hypothalamus but had no effect on DA levels using microdialysis. [1] Desvenlafaxine exhibits a linear and dose-proportional pharmacokinetic single-dose profile in a dose range from 100 to 600 mg/day. The absolute bioavailability of the oral formulation is 80.5%.[2]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
