Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective dopamine D2 receptor antagonist; also blocks alpha-1 adrenergic, histamine H1, and muscarinic M1 receptors.
Cyproheptadine is a first-generation antihistamine with anticholinergic and antiserotonergic properties. It acts as a competitive antagonist at histamine H1 receptors and serotonin 5-HT2 receptors, thereby inhibiting histamine-mediated allergic symptoms and serotonin-mediated effects such as increased gastrointestinal motility and vascular permeability.
Adults: 1 mg orally once daily.
4 mg orally three times daily; adjust as needed. Maximum: 32 mg/day.

12–15 hours in adults with normal renal function; prolonged to 30–40 hours in severe renal impairment (CrCl <30 mL/min).
10-12 hours terminal elimination half-life; steady-state reached in 2-3 days
Renal: 80% as unchanged drug; biliary/fecal: 15% as metabolites; <5% unchanged in feces.
Renal (40-50% as metabolites, <5% unchanged); biliary/fecal (minor, ~10-20%)
