IODOHIPPURATE SODIUM I 131 vs PULMOLITE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Iodohippurate sodium I 131 is a radioactive diagnostic agent that is actively transported by the renal tubules, allowing imaging of renal morphology and function. The iodine-131 emits gamma radiation, enabling scintigraphic evaluation of renal blood flow, tubular secretion, and excretion.
PULMOLITE is a leukotriene receptor antagonist (LTRA) that selectively and competitively inhibits the cysteinyl leukotriene (CysLT1) receptor in the human airway, thereby reducing bronchoconstriction, mucus secretion, and eosinophilic infiltration.
Adult: 5-30 microcuries (0.185-1.11 MBq) intravenously for renal function studies.
Adults: 200 mg intravenously every 12 hours over 30 minutes.

Terminal elimination half-life is approximately 60 minutes in patients with normal renal function. In renal impairment, half-life may be prolonged up to several hours, correlating with reduced clearance.
Terminal elimination half-life: 12 hours (range 10–14 h) in adults with normal renal function (CrCl >90 mL/min); prolonged to 24–30 h in severe renal impairment (CrCl <30 mL/min).
Primarily renal; >90% of administered dose excreted unchanged in urine within 24 hours via glomerular filtration and tubular secretion. Fecal excretion <2%.
Primarily renal (80%) as unchanged drug; 15% fecal via biliary excretion; 5% metabolized.
