In vivo batch selection In vivo Batch:
Homogeneous suspension	CMC-NA	≥5mg/ml	Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O Validated by Selleck labs. Should you need adjustments to this formulation, contact our sales team for custom testing.	2.85mg/ml (10.08mM)	Taking the 1 mL working solution as an example, add 50 μL of 57 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.

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.

Mechanism of Action

Targets/IC₅₀/Ki	norepinephrine transporter (NET) 77 nM norepinephrine transporter (SERT) 420 nM
In vitro	Milnacipran is mainly excreted in the urine as the parent and glucoronide (> 80%), and only a small fraction (< 10%) is metabolized via N-de-ethylation by the CYP3A4 enzyme. Milnacipran at high concentration can inhibit certain ligand-gated ion-channel (LGIC) receptors, including NMDA, 5-HT3A and nACh receptors, with IC50 of 58.4 μM, 185 μM, 14.3 μM.
In vivo	Milnacipran (10 and 30 mg/kg, PO) causes a dose-related increase in the extracellular levels of 5-HT and NA in the medial prefrontal cortex of rats. Milnacipran (30 and 60 mg/kg, PO) significantly reduces the duration of both the immobility time in the forced swimming test and the freezing time in the conditioned fear stress test in rats, which are animal behavioral models for depression and anxiety, respectively. Milnacipran (<40 mg/kg i.p.) dose-dependently increases the extracellular levels of NA and 5-HT in hypothalamus of freely moving guinea pigs. Milnacipran administrated at 10 mg/kg and 40 mg/kg decreases NA metabolite MHPG levels by 57% and 47%, respectively, in hypothalamus of freely moving guinea pigs.
