It is less useful for motion sickness and vestibular nausea<\/strong> (where the dominant pathway is histaminergic and cholinergic — promethazine\/Avomine, cinnarizine, and meclozine work better) and not first-line for nausea-vomiting of pregnancy<\/strong> (NVP first-line is doxylamine + B6; ondansetron is reserved for refractory hyperemesis gravidarum after considering a small first-trimester cardiac\/cleft-palate signal in observational studies).<\/p>\n Ondem MD is supplied from a v\u00fdrobce certifikovan\u00e9ho WHO-GMP<\/strong>.

Ondansetron is the global standard for serotonin-driven emesis with millions of doses delivered safely each year. Orally disintegrating tablet (ODT\/MD) formulation is convenient when active vomiting prevents reliable swallowing.<\/p>\n Chemotherapy, radiation, and surgery damage gut enterochromaffin cells, which release massive amounts of serotonin (5-HT)<\/strong>. The serotonin binds 5-HT3 receptors on vagal afferents and on the chemoreceptor trigger zone (area postrema), which signal the medullary vomiting centre. Ondansetron is a highly selective antagonist at the 5-HT3 receptor — it blocks this signal at both peripheral and central sites without affecting D2, H1, muscarinic, or alpha-adrenergic receptors. That selectivity explains its clean side-effect profile: minimal sedation, no extrapyramidal reactions, no anticholinergic burden.<\/p>\nPro\u010d objedn\u00e1vat z MedsBase<\/h3>\n
