ACTIFED vs ALBALON
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ACTIFED contains triprolidine, a first-generation antihistamine that competitively inhibits histamine H1 receptors, and pseudoephedrine, a sympathomimetic amine that directly stimulates alpha-adrenergic receptors, causing vasoconstriction and decongestion.
Naphazoline is an imidazoline derivative that acts as a direct-acting sympathomimetic amine, stimulating alpha-adrenergic receptors in the conjunctival arterioles, resulting in vasoconstriction and decreased congestion.
1 tablet (pseudoephedrine HCl 60 mg, triprolidine HCl 2.5 mg) orally every 4-6 hours; maximum 4 tablets in 24 hours.
1-2 drops in affected eye(s) every 3-4 hours; frequency may be increased to every 2 hours in severe cases.

Triprolidine: 3.2 hours; Pseudoephedrine: 5–8 hours (pH-dependent: alkaline urine prolongs). Terminal half-life for clinical use typically 4–6 hours.
Terminal elimination half-life is 4-6 hours; clinically, dosing every 6-8 hours is recommended, with adjustments in renal impairment
Renal: 80% (20% unchanged, 60% as metabolites). Fecal: 20% (unchanged and metabolites). Active tubular secretion of pseudoephedrine.
Primarily renal excretion of unchanged drug (approximately 70-80%) with minor biliary/fecal elimination (10-15%)
