Biological Activity

Description	Phenazopyridine HCl is a local analgesic that has been used in urinary tract disorders. It is an inhibitor of sodium channel protein type 1 subunit alpha.

In vitro
In vitro	Phenazopyridine: (i) enhanced neuronal differentiation, (ii) increased cell survival, (iii) decreased the amount of non-neuronal and undifferentiated cells and (iv) synchronized the cellular differentiation state.

In Vivo
In vivo	Phenazopyridine can directly inhibit the mechanosensitive Aδ-fibers in the normal rat bladder.

Calculation results:

Working concentration: mg/ml;

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.
