Dexetimide is an anticholinergic agent used both clinically and in medical research. Clinically, it is employed to treat symptoms of Parkinson's disease, such as tremors and other movement disorders, by blocking muscarinic receptors and modulating cholinergic activity in the central nervous system. In pharmacology and research, it serves as a tool to study cholinergic blockade effects, acetylcholine dysfunction, and the balance between cholinergic and dopaminergic systems. It also acts as a reference compound in drug development targeting muscarinic receptors for neurological, psychiatric, and neurodegenerative disorders.
