CLONIDINE vs IOPIDINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective alpha-2 adrenergic agonist in the brainstem, activating inhibitory neurons, reducing sympathetic outflow, leading to decreased peripheral vascular resistance, renal vascular resistance, heart rate, and blood pressure.
Alpha-2 adrenergic agonist; reduces intraocular pressure by decreasing aqueous humor production and increasing uveoscleral outflow.
Adults: Initial 0.1 mg orally twice daily; maintenance 0.2-0.6 mg/day in divided doses. Transdermal: 0.1-0.3 mg/day patch applied every 7 days. Epidural infusion: 30-40 mcg/hour.
Adults: 1 drop of 0.5% or 1% ophthalmic solution in the affected eye(s) three times daily, beginning 48 hours prior to surgery and continuing on the day of surgery. Alternatively, for intraocular surgery, 1 drop of 1% solution is administered 1 hour before surgery and 1 drop immediately after surgery.

Terminal elimination half-life: 6-20 hours (mean 12 hours), prolonged in renal impairment (up to 40 hours).
0.5-2 hours (terminal) for topical ophthalmic administration; clinical effect may persist longer due to local tissue binding.
Renal: 40-60% unchanged; hepatic metabolism accounts for ~50%, with metabolites excreted renally. Fecal excretion <5%.
