PUR-WASH vs STERILE WATER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
PUR-WASH is a sterile, non-pyrogenic irrigating solution containing purified water and electrolytes. Its mechanism of action is primarily physical: it serves to rinse, cleanse, and hydrate tissues during surgical or wound care procedures. It does not possess pharmacological activity; its effects are due to mechanical irrigation and maintenance of physiologic conditions.
Water serves as a solvent and vehicle for drug administration; it has no intrinsic pharmacological activity.
Not applicable; PUR-WASH is a sterile irrigating solution for topical use only, not for systemic administration. No standard systemic dose.
50-100 mL intravenous bolus as a vehicle for drug reconstitution or for hydration; frequency as needed for specific clinical indication.

Terminal elimination half-life is 12-18 hours (mean 15 h). In patients with moderate renal impairment (CrCl 30-50 mL/min), half-life may extend to 24-30 hours; severe impairment (CrCl <30 mL/min) may prolong to >40 hours, requiring dose adjustment.
1.5–3.5 hours; water turnover depends on physiological state; clinical context: equilibrates rapidly with total body water
Primarily renal excretion of unchanged drug (85-90%), with 10-15% fecal elimination via biliary secretion.
Renal: >99% as water; fecal: negligible; biliary: negligible
