Mestinon, with the active ingredient pyridostigmine, is a prescription medication primarily used to manage myasthenia gravis (MG) in adults. It belongs to a class of drugs known as cholinesterase inhibitors. Myasthenia gravis is an autoimmune disorder where the body's immune system mistakenly attacks its own healthy cells, specifically targeting the communication points between nerves and muscles. This attack leads to weakness in the skeletal muscles, which can manifest in various ways, including drooping eyelids, double vision, and significant fatigue. In severe cases, MG can impair breathing and swallowing, posing a serious health risk.

Mestinon works by increasing the levels of a chemical messenger called acetylcholine in the body. Acetylcholine is crucial for transmitting signals from nerves to muscles. By inhibiting the enzyme that breaks down acetylcholine (cholinesterase), Mestinon allows acetylcholine to remain active for longer, thereby improving nerve-muscle communication and reducing muscle weakness.
