Abstract:
Correction of neuroleptic-induced parkinsonism in rats with two central cholinoblockers atropine and pentifine (acetylene aminoalcohol synthesized at Institute of Toxicology) were studied by measuring the content of acetylcholine in the striatum. The content of the transmitter secretion was estimated from the content of bound acetylcholine fraction in homogenates of the above-mentioned compartment of the brain. The results indicate that atropine and pentifine in doses equally effectively preventing catalepsy in rats had different effects on acetylcholine secretion in the striatum. Hence, cholinolytics with different pharmacological selective effects differently interact with central muscarine receptor subtypes.

Indirect-Acting Cholinergic Agonists: Mechanism of Action
Reversible inhibitors like edrophonium bind to a specific part of the enzyme called the anionic catalytic site. They form noncovalent bonds, which means they are not strongly attached to the enzyme. This creates a temporary and less stable enzyme–inhibitor complex, leading to...

At the neuromuscular junction, these agents work by inhibiting the breakdown of acetylcholine, allowing it to remain bound to the receptor and bind to nearby receptors. This process leads to repetitive firing of the endplate, causing muscle...
