Potential revival of cholinesterase inhibitors as drugs in veterinary medicine

Frontiers in Veterinary Science, 2023
The cholinergic system is involved in the regulation of all organ systems and has acetylcholine (ACh) as almost its only neurotransmitter. Any substance is called cholinergic if it can alter the action of acetylcholine. Cholinesterases (ChEs) are enzymes
