DEXCHLORPHENIRAMINE MALEATE vs PROMETH PLAIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dexchlorpheniramine maleate is a histamine H1 receptor antagonist that competitively blocks the effects of histamine at peripheral H1 receptors, reducing symptoms of allergic reactions such as vasodilation, increased vascular permeability, and smooth muscle contraction. It also has anticholinergic and sedative properties.
Antagonist at histamine H1 receptors; also exhibits anticholinergic, antiemetic, and sedative effects.
2 mg orally every 4-6 hours; maximum 12 mg/day
12.5-25 mg intramuscularly or intravenously every 4-6 hours as needed; maximum 100 mg/day.
