MULTRYS vs ZINC CHLORIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
MULTRYS is a multivitamin preparation for intravenous infusion; its components serve as coenzymes or cofactors in various metabolic pathways, including energy production, red blood cell formation, and antioxidant defense.
Zinc chloride exerts its effects primarily through inhibition of copper absorption and modulation of immune function. It competitively inhibits copper uptake at the intestinal mucosa, leading to copper deficiency, which is the basis for its use in Wilson's disease. Topically, it acts as an astringent and has antiseptic properties due to precipitation of proteins.
10 mL (one vial) intravenously three times per week, not to exceed 10 mL per dose.
Intravenous: 2.5-5 mg zinc (as chloride) per day, typically added to total parenteral nutrition (TPN) solutions.

Not applicable as a single entity; values vary by component. For example: thiamine 10-20 minutes (plasma), riboflavin 1-2 hours, vitamin B6 2-3 weeks (tissue stores), vitamin C 16 days (10-20 days for depletion), biotin 1-2 days, folic acid 3-4 hours (plasma), vitamin B12 4-5 days (plasma), zinc 2-3 days (plasma), copper 12-24 hours, selenium 11-20 days, chromium 0.5-1 day, manganese 5-10 days.
The terminal elimination half-life of zinc chloride is approximately 12-24 hours for the initial phase, with a longer terminal half-life of 2-3 months for the slow-turnover pool in bone and muscle. Clinically, this requires cautious monitoring during chronic supplementation to avoid accumulation.
Renal elimination of individual vitamins and trace elements varies; no intact drug is excreted, as MULTRYS is a mixture. Approximate ranges: thiamine 50% unchanged in urine, riboflavin 60-70% as metabolites in urine, vitamin B6 70-80% as 4-pyridoxic acid in urine, vitamin C 50% unchanged in urine, biotin 50% unchanged in urine, folic acid mainly as metabolites in urine, vitamin B12 via bile (50-60%) and urine (10-30%). Trace elements: zinc primarily fecal (90%), copper primarily fecal (80-90%), selenium primarily urine (50-60%), chromium primarily urine (80%), manganese primarily fecal (95-97%).
Zinc chloride is primarily excreted in the feces (approximately 90%) via biliary and pancreatic secretions, with renal excretion accounting for about 10% under normal homeostatic conditions. Unabsorbed zinc is eliminated in feces; absorbed zinc is mainly excreted through the gastrointestinal tract.
