Potassium chloride, also known as potassium salt, is used as a medication to treat and prevent low blood potassium. [2] Low blood potassium may occur due to vomiting, diarrhea, or certain medications. [3] The concentrated version should be diluted before use. [2] It is given by slow injection into a vein or by mouth. [4]
Potassium chloride (KCl, or potassium salt) is a metal halide salt composed of potassium and chlorine. It is odorless and has a white or colorless vitreous crystal appearance. The solid dissolves readily in water, and its solutions have a salt-like taste. Potassium chloride can be obtained from ancient dried lake deposits. [7]
Chloride channel openers refer to a specific category of drugs designed to modulate chloride channels in the human body. Chloride channels are anion-selective channels which are involved in a wide variety of physiological functions and processes such as the regulation of neuroexcitation, transepithelial salt transport, and smooth muscle contraction.

The United States Drug Enforcement Administration (DEA) maintains lists regarding the classification of illicit drugs (see DEA Schedules).It also maintains List I of chemicals and List II of chemicals, which contain chemicals that are used to manufacture the controlled substances/illicit drugs.
Potassium channel blockers exhibit reverse use-dependent prolongation of the action potential duration. Reverse use dependence is the effect where the efficacy of the drug is reduced after repeated use of the tissue. [11] This contrasts with (ordinary) use dependence, where the efficacy of the drug is increased after repeated use of the tissue.
A potassium channel opener is a type of drug which facilitates ion transmission through potassium channels. Examples. Some examples include:
Loop diuretics are 90% bonded to proteins and are secreted into the proximal convoluted tubule through organic anion transporter 1 (OAT-1), OAT-2, and ABCC4.Loop diuretics act on the Na +-K +-2Cl − symporter (NKCC2) in the thick ascending limb of the loop of Henle to inhibit sodium, chloride and potassium reabsorption.
The NKCC1 isoform consists of about 1,200 amino acids, with about 500 amino acids residues giving rise to twelve hydrophobic transmembrane regions. [5] However, evidence of a shorter NKCC1 mRNA transcript (6.7 kb to 7-7.5 kb) in skeletal muscle cells gives support that further NKCC1 variants exists in a tissue-specific manner. [6]
