Anticholinesterase drugs

Anticholinesterase drugs are medications that block the action of an enzyme called cholinesterase, which breaks down the neurotransmitter acetylcholine. By preventing this breakdown, these drugs increase the levels and activity of acetylcholine in the nervous system. This enhanced signaling can improve communication between nerves and muscles, making them useful for conditions like myasthenia gravis (a muscle weakness disorder) and Alzheimer's disease (a memory loss condition). Essentially, anticholinesterase drugs help boost nerve signals that are impaired in these disorders, improving muscle strength and cognitive functions.
