Descrição

Application

Chlorzoxazone may be used:

• as a calcium-activated potassium (K_Ca) channel activator in patch-clamp electrophysiology to test its effect on dendritic hyperexcitability[1]
• as a substrate for cytochrome P450 2E1 (CYP2E1) enzyme in cultured human hepatocytes[2]
• as a benzimidazolone compound to test its effect on epithelial sodium (Na⁺) transport[3]

Biochem/physiol Actions

Chlorzoxazone inhibits the multisynaptic reflex arcs primarily in the spinal cord and brain subcortical areas.[4] It is an activator of calcium activated potassium channels and may contribute to the aortic artery relaxation in mice.[5] Chlorzoxazone also activates the calcium-activated potassium (K_Ca) channel and small conductance calcium-activated potassium channels (SK).[1] It is metabolized by cytochrome P450 2E1 (CYP2E1) and serves as a probe for monitoring this enzyme function.[6]

Chlorzoxazone is a skeletal muscle relaxant.
