Pharmacological Actions of Potassium Channel Openers on Voltage-Gated Potassium Channels.

ABSTRACT: Background/Objectives: Potassium (K⁺) channels are essential transmembrane proteins that regulate ion flow, playing a critical role in regulating action potentials and neuronal transmission. Although K⁺ channel openers (agonists, K⁺ Ag) are widely used in treating neurological and psychiatric disorders, their precise mechanisms of action remain unclear. Our study explored how K⁺ channel openers might influence the expression of voltage-gated K⁺ channels (Kv) in rat brain. Methods: Briefly, eight rats per group received intraperitoneal injections of diazoxide (Dia), chlorzoxazone (Chl), or flupirtine (Flu). Two hours post-injection, the prefrontal cortex (PFC), nucleus accumbens (NAc), dorsal striatum (dSTR), dorsal hippoc
