Pikamilone sodium salt is primarily used in research settings as a tool to study the effects of GABAergic systems in the brain. It is often employed in neuropharmacology experiments to investigate the modulation of GABA receptors, which play a crucial role in regulating neuronal excitability. This compound is particularly useful for understanding the mechanisms underlying anxiety, epilepsy, and other neurological disorders. Additionally, it serves as a reference standard in analytical chemistry for the identification and quantification of similar compounds in various biological samples. Its application extends to preclinical studies, where it helps in evaluating the efficacy and safety of potential therapeutic agents targeting the GABAergic pathway.
