PULMOLITE vs SODIUM CHROMATE CR 51
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Radiolabeled sodium chromate (51Cr) binds to red blood cells, tagging them for survival studies. 51Cr emits gamma radiation, allowing detection and quantification of RBC mass and survival via scintillation counting or imaging.
Adults: 200 mg intravenously every 12 hours over 30 minutes.
Intravenous injection, 5-30 microcuries (0.185-1.11 MBq) as a single dose.

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).
The biological half-life is approximately 27–30 days. Clinically, gradual clearance from blood and tissues occurs over weeks to months.
Primarily renal (80%) as unchanged drug; 15% fecal via biliary excretion; 5% metabolized.
Primarily renal. Approximately 90% of absorbed dose is excreted in urine within 48 hours. Fecal excretion accounts for less than 5%.
