Used primarily in the treatment of myasthenia gravis, a neuromuscular disorder characterized by muscle weakness. It works by enhancing the transmission of nerve signals to muscles, improving muscle strength and function. Commonly prescribed to manage symptoms such as drooping eyelids, difficulty swallowing, and limb weakness. Also utilized in military and occupational settings as a pretreatment to protect against nerve agent poisoning, specifically organophosphates, by reversibly binding to acetylcholinesterase and limiting irreversible inhibition by toxic agents. Administered orally in tablet or liquid form, with dosing adjusted based on individual response and symptom severity.
