BRONKOMETER vs POLMON
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Beta-2 adrenergic receptor agonist; relaxes bronchial smooth muscle by increasing cyclic AMP.
Polmon (polymyxin B) is a cationic polypeptide antibiotic that disrupts bacterial cell membrane integrity by binding to lipopolysaccharides and phospholipids in the outer membrane, increasing permeability and causing cell death.
Isoetharine mesylate 0.5% solution: 2-4 inhalations every 4 hours as needed via hand-held nebulizer or IPPB.
1-2 mg intravenously every 2-4 hours as needed; maximum 8 mg/day.

Terminal elimination half-life: 2-3 hours; clinically, bronchodilation persists but dosing interval is 3-4 hours due to rapid onset and offset.
Terminal elimination half-life is 12-18 hours in healthy adults; prolonged to 24-36 hours in severe hepatic impairment requiring dose adjustment.
Renal: 10-15% unchanged; 70-80% as sulfate conjugates; biliary/fecal: <5%.
Renal excretion of unchanged drug accounts for 40-50% of elimination; biliary/fecal excretion accounts for 50-60%.
