Dalfampridine, A potassium channel blocker has also been approved for use in the treatment of multiple sclerosis. [ 8 ] A study appears to indicate that topical spray of a selective Tandem pore Acid-Sensitive K+ (TASK 1/3 K+) (potassium antagonist) increases upper airway dilator muscle activity and reduces pharyngeal collapsibility during ...

The following table contains a comparison of the major classes of potassium channels with representative examples (for a complete list of channels within each class, see the respective class pages). For more examples of pharmacological modulators of potassium channels, see potassium channel blocker and potassium channel opener.

Molecules that act as channel blockers are important in the field of pharmacology, as a large portion of drug design is the use of ion channel antagonists in regulating physiological response. The specificity of channel block molecules on certain channels makes it a valuable tool in the treatment of numerous disorders.
Four genes have been identified as members of the K ATP gene family. The sur1 and kir6.2 genes are located in chr11p15.1 while kir6.1 and sur2 genes reside in chr12p12.1. The kir6.1 and kir6.2 genes encode the pore-forming subunits of the K ATP channel, with the SUR subunits being encoded by the sur1 (SUR1) gene or selective splicing of the sur2 gene (SUR2A and SUR2B).
Compared with certain other L-type calcium channel blockers (for example those of the phenylalkylamine class such as verapamil) that have significant action at the heart, the dihydropyridine calcium channel blockers lower blood pressure mainly by relaxing the smooth muscle of the blood vessel walls.
