M.V.I.-12 LYOPHILIZED vs MULTRYS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Provides essential vitamins for normal metabolic function, acting as cofactors in enzymatic reactions, including energy production, red blood cell synthesis, and antioxidant defense.
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.
10 mL (one vial) intravenously once daily, infused over at least 30 minutes.
10 mL (one vial) intravenously three times per week, not to exceed 10 mL per dose.

Variable by vitamin: thiamine ~24h, riboflavin ~18h, pyridoxine ~30h, cyanocobalamin ~6 days, ascorbic acid ~8h, retinol ~20h, ergocalciferol ~19 days, alpha-tocopherol ~10h, phytonadione ~4h. Clinical context: short t1/2 of water-soluble vitamins requires daily dosing; long t1/2 of fat-soluble vitamins allows less frequent dosing but risk of accumulation.
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.
Renal: water-soluble vitamins (B-complex, C) are excreted primarily via kidneys, with excess eliminated unchanged. Fat-soluble vitamins (A, D, E, K) are eliminated via bile and feces; renal excretion is minimal. Specific percentages: thiamine 80-90% renal, riboflavin 60-70% renal, pyridoxine 70-80% renal, cyanocobalamin 50-60% renal, ascorbic acid 60-70% renal; fat-soluble vitamins >90% biliary/fecal.
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%).
