MULTIFUGE vs MULTRYS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Multifuge is a combination product containing an antihistamine and a decongestant. The antihistamine (chlorpheniramine) competitively antagonizes histamine H1 receptors, reducing allergic symptoms. The decongestant (pseudoephedrine) stimulates alpha-adrenergic receptors, causing vasoconstriction and reducing nasal congestion.
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.
IV: 10 mg/kg body weight as a single dose; repeated every 48 hours as needed.
10 mL (one vial) intravenously three times per week, not to exceed 10 mL per dose.

The terminal elimination half-life is 7-9 hours in adults with normal renal function. This may be prolonged (up to 20-30 hours) in patients with severe renal impairment (CrCl <30 mL/min), necessitating dose adjustment.
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 excretion of unchanged drug accounts for 60-70% of the administered dose, with the remainder undergoing hepatic metabolism to inactive metabolites that are excreted renally. Fecal elimination is minimal (<5%).
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%).
