POLMON vs TORNALATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Beta-2 adrenergic receptor agonist; relaxes bronchial smooth muscle by increasing cyclic AMP.
1-2 mg intravenously every 2-4 hours as needed; maximum 8 mg/day.
2 puffs (340 mcg) inhaled via oral inhalation 4 times daily; maximum 12 puffs/day.

Terminal elimination half-life is 12-18 hours in healthy adults; prolonged to 24-36 hours in severe hepatic impairment requiring dose adjustment.
Terminal elimination half-life is approximately 9-12 hours in healthy adults. May be prolonged in elderly or those with hepatic impairment, necessitating dose adjustment.
Renal excretion of unchanged drug accounts for 40-50% of elimination; biliary/fecal excretion accounts for 50-60%.
Primarily renal excretion of unchanged drug and metabolites; <10% fecal. Approximately 60-70% of a dose is recovered in urine as unchanged drug and glucuronide conjugates within 24 hours.
