Neostigmine is a medication used to treat myasthenia gravis, a condition where muscles weaken due to a breakdown in communication between nerves and muscles. It works by preventing the breakdown of acetylcholine, a neurotransmitter essential for muscle function. This allows acetylcholine to accumulate and stimulate muscle receptors, improving muscle strength. It's like giving your muscles a boost! ๐ช It's also used to reverse the effects of certain muscle relaxants after surgery.
