ACTAHIST vs CLISTIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Antihistamine; binds to histamine H1 receptors, blocking the effects of histamine; also exhibits anticholinergic and mild sedative properties.
Clistin (histamine-1 receptor antagonist) competitively blocks histamine at H1 receptor sites, inhibiting vasodilation, increased capillary permeability, and bronchoconstriction. It also has anticholinergic and sedative properties.
1.34 mg (one capsule) orally twice daily.
4 mg orally every 4-6 hours as needed; maximum 24 mg/day.

6.9 ± 1.7 hours in adults; prolonged to 12-18 hours in elderly or patients with hepatic impairment, requiring dosing interval adjustment.
Terminal elimination half-life is approximately 8-12 hours in healthy adults. In patients with renal impairment, half-life may be prolonged, requiring dose adjustment.
Primarily renal (approximately 85% as unchanged drug and metabolites) and fecal (15%) via biliary elimination.
Primarily renal excretion (approximately 85-90% as unchanged drug and metabolites). Biliary/fecal elimination accounts for the remainder (10-15%).
