MULTRYS vs MVC PLUS
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.
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.
10 mL (one vial) intravenously three times per week, not to exceed 10 mL per dose.
10 mg orally once daily.

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