ZINC CHLORIDE vs ZINC SULFATE
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 sulfate provides essential zinc, a cofactor for over 300 enzymes involved in cell division, DNA synthesis, immune function, and wound healing. It stabilizes cell membranes and has antioxidant properties.
Intravenous: 2.5-5 mg zinc (as chloride) per day, typically added to total parenteral nutrition (TPN) solutions.
For zinc deficiency: 220 mg (containing 50 mg elemental zinc) orally three times daily. For maintenance: 110 mg (25 mg elemental zinc) orally once daily.

moderateZinc sulfate + Dolutegravir
"The serum concentration of Dolutegravir can be decreased when it is combined with Zinc sulfate."
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.
The terminal elimination half-life of zinc sulfate is approximately 2.5-3 hours in normal subjects; however, the whole-body turnover half-life is considerably longer (12-14 days), reflecting redistribution from exchangeable pools.
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.
Zinc is primarily excreted in feces (approximately 90%) via biliary and pancreatic secretions, with renal excretion accounting for about 2-10% of total elimination. Minor amounts are lost in sweat and sloughed intestinal cells.
