Zinc supplementation in pregnancy has been studied, with little cause for concern. Interactions Zinc may decrease the plasma concentrations of certain quinolone eg, ciprofloxacin and tetracycline antibiotics, as with other divalent metals, such as calcium.
Interference with absorption and metabolism of iron, copper, and vitamin A has been described. Adverse Reactions The most common adverse reactions of oral zinc are nausea, bad taste, diarrhea, vomiting, mouth irritation, and, rarely, mouth sores.
Nasal and throat irritation may occur with the zinc spray. There have been case reports of apparent zinc-induced copper deficiency, immune system dysfunction, and myeloneuropathy. An increase in genitourinary symptoms and prostate cancer has been related to zinc supplementation.
Toxicology Information is lacking. History Zinc is an essential trace element necessary for normal human functioning. It serves as an enzyme cofactor and protects cell membranes from lysis caused by complement activation and toxin release. Zinc is not stored in the body; therefore, dietary intake is required.
Meat and seafood are rich in zinc. Aside from dietary zinc supplementation, zinc has been studied for therapeutic use in the common cold, atopic eczema, psoriasis, acne vulgaris, degenerative retinal lesions, age-related macular degeneration, inflammatory bowel disease, and various other disorders.
Zinc gluconate, zinc gluconate-glycine, and zinc acetate have been studied most often in the lozenge form for the treatment of the common cold.
Uses and Pharmacology Trials evaluating the efficacy of zinc versus placebo or a comparator drug are likely to have methodological issues related to blinding, as the taste of the zinc preparation is difficult to mask.
Therefore, subjective outcomes are likely to be affected by bias. Trials evaluating the effect of zinc supplementation in the management of type 2 diabetes have found conflicting results, including no difference in serum zinc levels, 20 no effect on glucose, 21 reductions in total cholesterol and triglycerides, 21 and improved antioxidant status.
Insufficient data are available from these trials on mortality outcomes, and vomiting was found to be more common among zinc-treated children than placebo-treated children. Fertility Several trials have evaluated the relationship between zinc deficiency and male fertility, but direct causality is not established.
Decreased serum zinc levels have been found in these patients. The exact mechanism of action of zinc ions is still controversial but may involve a combination of actions. According to in vitro studies, zinc ions interfere with rhinoviral capsid proteins, thereby altering protease activity.
It has also been suggested that zinc may interfere with viral docking and the resulting inflammatory process. An earlier Cochrane systematic review now withdrawn pending an update was conservative in its recommendations regarding the role of zinc in the management of the common cold.
Baseline serum zinc was not measured. Other authors suggest a more conservative approach, as mixed results have been found, and suggest zinc may even be harmful in children with bacterial pneumonia.
