ALBALON vs DRYTEC
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Drytec is an antihistamine that selectively inhibits peripheral H1 receptors, reducing histamine-mediated allergic symptoms.
1-2 drops in affected eye(s) every 3-4 hours; frequency may be increased to every 2 hours in severe cases.
1-2 tablets (paracetamol 500 mg/pseudoephedrine 30 mg) orally every 4-6 hours; maximum 8 tablets per day.

Terminal elimination half-life is 4-6 hours; clinically, dosing every 6-8 hours is recommended, with adjustments in renal impairment
Terminal elimination half-life is approximately 3.5 to 4 hours in adults with normal renal function; may be prolonged in elderly or patients with renal impairment.
Primarily renal excretion of unchanged drug (approximately 70-80%) with minor biliary/fecal elimination (10-15%)
Renal excretion of unchanged drug accounts for approximately 65% of the administered dose; fecal/biliary elimination contributes about 35%.
