Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Zinc is an essential trace element that serves as a cofactor for numerous enzymes involved in protein synthesis, nucleic acid metabolism, and cell division. It stabilizes cell membranes and modulates immune function. In wound healing, zinc promotes epithelialization and collagen synthesis.
Intravenous: 2.5-5 mg zinc (as chloride) per day, typically added to total parenteral nutrition (TPN) solutions.
For total parenteral nutrition: 2.5-5 mg zinc (as zinc chloride) per day intravenously. For zinc deficiency: 0.5-1 mg zinc/kg/day IV. Route: IV infusion. Frequency: Daily.

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.
Terminal elimination half-life is approximately 1-2 hours for ionic zinc, but may be prolonged up to 12-24 hours in zinc-replete states due to redistribution. Clinical context: short half-life supports frequent dosing in parenteral nutrition.
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.
Primarily renal (fecal minimal). Urinary excretion accounts for >90% of absorbed zinc. Biliary excretion is negligible.
