# Zinc (Dispersible Tablets - DT) ## Overview Zinc is an essential trace element involved in nucleic acid synthesis, protein metabolism, and immune function. Dispersible tablets (DT) are designed to dissolve rapidly in a small volume of water, facilitating administration in pediatric populations and patients with dysphagia. ## Primary Indications * **Acute Diarrhea:** Adjunctive therapy to reduce duration and severity in children. * **Zinc Deficiency:** Treatment and prevention of states resulting from malabsorption, inadequate intake, or increased loss. ## Adult Dosing * **Zinc Deficiency:** 25–50 mg elemental zinc daily. * **Note:** Dosing varies significantly by indication (e.g., Wilson's disease requires higher doses, typically 50 mg three times daily). ## Pediatric Dosing * **Acute Diarrhea (WHO/UNICEF guidelines):** * Infants (under 6 months): 10 mg elemental zinc once daily for 10–14 days. * Children (6 months and older): 20 mg elemental zinc once daily for 10–14 days. * **Maintenance/Deficiency:** Generally 0.5–1 mg/kg/day; exact dosing requires clinical evaluation of baseline status. ## Dose Adjustments * **Renal Impairment:** No specific standard adjustment, but monitor for accumulation in severe impairment. * **Hepatic Impairment:** Use caution; zinc is primarily excreted via the gastrointestinal tract, but chronic administration in liver disease requires caution. ## Contraindications * Hypersensitivity to zinc or any component of the formulation. * Avoid in patients with acute copper deficiency unless managed under close supervision. ## Adverse Effects * **Gastrointestinal:** Nausea, vomiting, metallic taste, epigastric pain, and diarrhea. * **Long-term high-dose risks:** Copper deficiency (manifesting as anemia or neutropenia) and impaired immune function due to copper antagonism. ## Key Drug Interactions * **Antibiotics:** Zinc significantly reduces the absorption of fluoroquinolones and tetracyclines (separate doses by at least 2–4 hours). * **Chelating Agents:** Penicillamine and trientine decrease zinc absorption; space doses by at least 2 hours. * **Iron Supplements:** Concurrent high-dose iron may reduce zinc absorption. ## Monitoring * **Clinical:** Resolution of diarrhea or symptoms of deficiency. * **Laboratory:** For chronic long-term use, monitor serum copper and zinc levels, and complete blood count (CBC) to rule out sideroblastic anemia induced by copper deficiency. ## Clinical Pearls * **Administration:** Disperse the tablet in a small amount of clean water or breast milk/formula before administration. Do not swallow whole. * **GI Sensitivity:** To minimize gastric irritation, take with meals. * **Copper Balance:** Prolonged supplementation of zinc (>50 mg/day) may necessitate small amounts of copper supplementation to prevent secondary deficiency. * **Variability:** Always verify the specific salt form (e.g., zinc sulfate, gluconate, or acetate) as the amount of *elemental* zinc varies by compound. *** **Educational Disclaimer:** This information is for educational purposes only.
