WebHyoscine works by blocking the cholinergic input from the vestibular organs to the CNS, thereby inhibiting the vomiting impulse activated by motion sickness. Hyoscine is available in several forms, including oral tablets, as an IV, as a topical gel application or as adhesive transdermal patches. WebMuscarinic receptors are activated by ACh released by the postganglionic parasympathetic nerves and thus mediate the actions of the parasympathetic nervous system. In addition, muscarinic receptors mediate the actions of the sympathetic cholinergic nerves ( e.g. sweating). Drugs affecting cholinergic neurotransmission
WebBeing ionotropic receptors, overstimulation can lead to depolarization blockade. Thus, there is the potential for both agonists and antagonists to inhibit ganglionic neurotransmission. Although ganglion blocking drugs have been used in the past in the treatment of hypertension, they are now considered clinically obsolete.
