An epithelial sodium channel blocker is a sodium channel blocker that is selective for the epithelial sodium channel. An example is amiloride , which is used in the treatment of hypertension . [ 1 ]
Sodium channel blockers are also used as local anesthetics and anticonvulsants. [5] Sodium channel blockers have been proposed for use in the treatment of cystic fibrosis, [6] but current evidence is mixed. [7] It has been suggested that the analgesic effects of some antidepressants may be mediated in part via sodium channel blockade. [8]
For example, TTX can bind and inactivate voltage-gated sodium channels, despite the fact that TTX is much larger and chemically different than sodium ions. Given the disparities in size and chemical properties between TTX and a sodium ion, this is an example of structure being used to block usually specific channels.
Examples of targets for modulators include: Voltage-gated ion channels. Calcium channel: see also Calcium channel blocker, Calcium channel opener; Potassium channel: see also Potassium channel blocker, Potassium channel opener; Sodium channel: see also Sodium channel blocker, Sodium channel opener
Procainamide (PCA) is a medication of the antiarrhythmic class used for the treatment of cardiac arrhythmias.It is a sodium channel blocker of cardiomyocytes; thus it is classified by the Vaughan Williams classification system as class Ia.
A channel opener, also known as a channel activator, is a type of drug which facilitates ion flow through ion channels. They include the following: Potassium channel openers; Calcium channel openers; Sodium channel openers; Chloride channel openers

The epithelial sodium channel (ENaC), (also known as amiloride-sensitive sodium channel) is a membrane-bound ion channel that is selectively permeable to sodium ions (Na +).It is assembled as a heterotrimer composed of three homologous subunits α or δ, β, and γ, [2] These subunits are encoded by four genes: SCNN1A, SCNN1B, SCNN1G, and SCNN1D.
