ALBALON vs MOTPOLY XR
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.
MOTPOLY XR is a combination of an opioid agonist (morphine) and an opioid antagonist (naltrexone). The extended-release formulation allows for sequential release: an initial morphine dose followed by naltrexone, which mitigates opioid-induced adverse effects by antagonizing mu-opioid receptors in the gastrointestinal tract without affecting central analgesia.
1-2 drops in affected eye(s) every 3-4 hours; frequency may be increased to every 2 hours in severe cases.
Adults: 10 mg orally once daily, with or without food.

Terminal elimination half-life is 4-6 hours; clinically, dosing every 6-8 hours is recommended, with adjustments in renal impairment
Terminal half-life 12–15 hours; requires dose adjustment in renal impairment (CrCl <30 mL/min).
Primarily renal excretion of unchanged drug (approximately 70-80%) with minor biliary/fecal elimination (10-15%)
Renal: ~60% unchanged; biliary/fecal: ~25% as metabolites; <5% unchanged in feces.
