Zinc Cr

Uses

Zinc Cr is a drug used to replenish low levels of zinc or prevent zinc deficiency, or to test for zinc deficiency.

This medication is a mineral used to treat or prevent low levels of zinc alone and together with oral rehydration therapy (ORT). It is also used as a topical astringent. Zinc Sulfate Injection, USP is indicated for use as a supplement to intravenous solutions given for TPN.

Zinc Cr is also used to associated treatment for these conditions: Dry Eyes, Local itching, Localized pain, Localized swelling, Nutritional supplementation

How Zinc Cr works

Zinc inhibits cAMP-induced, chloride-dependent fluid secretion by inhibiting basolateral potassium (K) channels, in in-vitro studies with rat ileum. This study has also shown the specificity of Zn to cAMP-activated K channels, because zinc did not block the calcium (Ca)-mediated K channels. As this study was not performed in Zn-deficient animals, it provides evidence that Zn is probably effective in the absence of Zn deficiency. Zinc also improves the absorption of water and electrolytes, improves regeneration of the intestinal epithelium, increases the levels of brush border enzymes, and enhances the immune response, allowing for a better clearance of the pathogens.

Toxicity

Human : TDLo ( Oral) 45mg/kg/7D-C : Normocytic anemia, pulse rate increase without fall inBP Human: TDLo (oral) 106mg/kg : Hypermotylity, diarrhea Mouse ; LD50 Oral : 245mg/kg Mouse : LD50 : subcutaneous : 781mg/kg

Food Interaction

• Avoid milk and dairy products. Separate the use of zinc from these products by at least 2 hours before administration. Separate for 2 hours after administration if these products also contain phosphorus.
• Do not take with bran and high fiber foods. For optimal absorption, take zinc at least 2 hours before or after eating high-fiber foods.
• Take on an empty stomach. Take at least 1 hour before and 2 hours after eating for optimal absorption. Zinc can be taken with food to reduce gastrointestinal upset.

Volume of Distribution

After absorption zinc is bound to protein metallothionein in the intestines. Zinc is widely distributed throughout the body. It is primarily stored in RBCs, WBCs, muscles, bones, Skin, Kidneys, Liver, Pancreas, retina, and prostate.

Elimination Route

Approximately 20 to 30% of dietary zinc is absorbed, primarily from the duodenum and ileum. The amount absorbed is dependent on the bioavailability from food. Zinc is the most bioavailable from red meat and oysters. Phytates may impair absorption by chelation and formation of insoluble complexes at an alkaline pH. After absorption, zinc is bound in the intestine to the protein metallothionein. Endogenous zinc can be reabsorbed in the ileum and colon, creating an enteropancreatic circulation of zinc.

Half Life

3 hours

Elimination Route

Primarily fecal (approximately 90%); to a lesser extent in the urine and in perspiration.
