MVC PLUS vs ZINC CHLORIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
MVC PLUS is a fixed-dose combination of maraviroc, a CCR5 co-receptor antagonist, and lamivudine, a nucleoside reverse transcriptase inhibitor. Maraviroc binds to CCR5 on CD4+ T cells blocking HIV-1 entry; lamivudine inhibits HIV reverse transcriptase via competitive inhibition and chain termination.
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 mg orally once daily.
Intravenous: 2.5-5 mg zinc (as chloride) per day, typically added to total parenteral nutrition (TPN) solutions.

Terminal elimination half-life: 12-18 hours (mean 14 hours). Clinically, this supports twice-daily dosing with steady-state achieved in ~3 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: ~70% unchanged; Fecal: ~25%; Biliary: <5%
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.
