The epithelial sodium channel (ENaC) is a membrane-bound ion-channel that is permeable to protons, Li+-ions, and especially Na+-ions. It is a constitutively active ion-channel. It can be argued that it is the most selective ion channel. In vertebrates, the channels control reabsorption of sodium in kidney, colon, lung and sweat glands. They also play a role in taste perception. Amiloride is a relatively selective inhibitor of the epithelial sodium channel (ENaC).
In vitro: Amiloride is a relatively poor inhibitor of the the Na+/H+ exchanger (NHE) with an IC50 of 3 μM in the presence of a low external [Na+] but as high as 1 mM in the presence of a high [Na+]. Amiloride completely inhibits Na+ influx in doses of 1.5 μM in vascular smooth muscle cells .
In vivo: Amiloride at 1 mg/kg/day is found to reverse the initial increases in collagen deposition and prevent further increases in the DOCA-salt hypertensive rat. Amiloride delays the onset of proteinuria and improved brain and kidney histologic scores in the stroke-prone spontaneously hypertensive rats. Amiloride antagonizes or prevents actions of aldosterone in cardiovascular and renal tissues in animals with salt-dependent forms of hypertension .
Clinical trial: Amiloride is a potassium-sparing diuretic, first approved for use in 1967, used in the management of hypertension and congestive heart failure. Amiloride was also tested as treatment of cystic fibrosis, but it was revealed inefficient in vivo due to its short time of action.

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.
