Physostigmine

Physostigmine is a medication that helps improve communication between nerves and muscles by blocking an enzyme called acetylcholinesterase. This enzyme normally breaks down a chemical called acetylcholine, which is essential for transmitting nerve signals. By stopping this breakdown, physostigmine increases acetylcholine levels, enhancing nerve-to-muscle signals. It is used to treat certain poisoning cases from drugs or plants that affect nerve function and can also help with specific eye conditions. Its effects are temporary, and it must be administered carefully under medical supervision to avoid side effects.
