MACROTEC vs SALPIX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Not applicable for diagnostic use.
SALPIX (sodium chloride 0.9%, benzyl alcohol 0.9%) is a sterile, nonpyrogenic isotonic solution. It does not have a direct pharmacological mechanism of action; it is used as a vehicle or diluent for other medications and for irrigation. The benzyl alcohol component acts as a bacteriostatic preservative.
5 mCi (185 MBq) intravenously as a single dose for lung perfusion imaging.
SALPIX (hysterosalpingography contrast medium) is administered intrauterine as a single dose of 10-20 mL, instilled slowly under fluoroscopic guidance. No systemic dosing; procedure is diagnostic.

6 hours; prolonged in renal impairment (up to 30 hours in ESRD)
Terminal elimination half-life: 1.5–2.0 hours. Short half-life necessitates frequent dosing in clinical use.
Renal: 95% as unchanged drug; biliary/fecal: <5% as metabolites
Primarily renal excretion as unchanged drug: >90% within 24 hours. Minor biliary/fecal elimination (<10%).
