MULTIFUGE vs ZINC SULFATE
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.
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.
IV: 10 mg/kg body weight as a single dose; repeated every 48 hours as needed.
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.

Clinical Note
moderateZinc sulfate + Dolutegravir
"The serum concentration of Dolutegravir can be decreased when it is combined with Zinc sulfate."
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.
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.
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%).
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.
