- Dopaminergic Blockade: In the brain's "vomiting center," it blocks dopamine receptors, providing strong anti-nausea and anti-vomiting effects.
- Muscarinic Receptor Inhibition: Its anticholinergic properties help reduce secretions and alleviate symptoms of motion sickness by acting on the inner ear's vestibular system.
