Neostigmine

Neostigmine is a medication used to improve muscle strength by enhancing communication between nerves and muscles. It works by blocking an enzyme that breaks down a chemical called acetylcholine, which is essential for muscle contraction. This helps in conditions like myasthenia gravis, where muscles become weak, and after certain surgeries to restore muscle activity. Neostigmine is typically administered under medical supervision because it affects how muscles function and can have side effects if not used properly.
