Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Naphazoline acts as an agonist at alpha-adrenergic receptors in the vascular smooth muscle of the conjunctiva, causing vasoconstriction and reducing redness.
Imidazoline sympathomimetic amine that stimulates alpha-2 adrenergic receptors in the nasal vasculature, producing vasoconstriction and reducing nasal congestion.

Terminal elimination half-life is 9-11 hours; clinically, steady state is reached after 2-3 days of regular dosing.
Terminal elimination half-life is approximately 3-4 hours; clinically, this supports dosing every 8-12 hours.
Renal excretion of unchanged drug (65%) and metabolites (35%); less than 1% fecal.
Renal elimination of unchanged drug and metabolites accounts for approximately 50% of the dose; fecal elimination is minimal.
