Research & Pharmacology Context
-
Used experimentally to model chemotherapy- or surgery-induced nausea and vomiting in animals. Typical first-day dose: 5?mg IV, followed by oral dosing for 5 days.
-
Exhibits high plasma volume of distribution (400–600?L), protein binding (~60–71%), and variable half-life (7–30?hrs dependent on CYP2D6 metabolism).
-
Also shows anti-inflammatory and neuroprotective effects via ?7-nicotinic acetylcholine receptor agonism in preclinical studies.
Research Applications
-
Chemotherapy-induced emesis models (e.g., cisplatin-induced)
-
Postoperative nausea protocols in animal studies
-
Mechanism-of-action studies involving serotonin signaling
-
Neuroprotection research, via ?7 nAChR pathways and inflammation modulation
