Definition: Tropidine is a chemical compound that is commonly used as an anticholinergic. It belongs to the class of compounds known as cholinesterase inhibitors, which are responsible for blocking the action of acetylcholine, a neurotransmitter in the brain. The primary function of tropidine is to inhibit the synthesis and release of acetylcholine from the synaptic vesicles in the neuron. Tropidine acts by binding to the acetylcholine receptor on the surface of the neurons
