Galzin (Zinc Acetate) - Summary

GALZIN SUMMARY

Zinc acetate as the dihydrate is a salt of zinc used to inhibit the absorption of copper in patients with Wilson's disease.

Zinc acetate therapy is indicated for maintenance treatment of patients with Wilson’s disease who have been initially treated with a chelating agent (See PRECAUTIONS: Monitoring Patients).

A randomized controlled trial of oral zinc in acute pneumonia in children aged between 2 months to 5 years. [2011.09]
OBJECTIVE: To evaluate the effectiveness and safety of zinc supplementation as adjuvant in treatment of pneumonia... CONCLUSIONS: Though well tolerated; the addition of zinc does not improve symptom duration or cure rate in acute bacterial pneumonia in under-five children.

Zinc lozenges as cure for the common cold--a review and hypothesis. [2010]
A 7-day reduction in duration of common colds was shown by Eby et al.Due to inadequate lozenge iZn very few of more than 40 different brands of zinc lozenges on the US market are expected to have any effect on the duration or severity of common colds.

Duration and severity of symptoms and levels of plasma interleukin-1 receptor antagonist, soluble tumor necrosis factor receptor, and adhesion molecules in patients with common cold treated with zinc acetate. [2008.03.15]
BACKGROUND: Zinc lozenges have been used for treatment of the common cold; however, the results remain controversial... CONCLUSION: Administration of zinc lozenges was associated with reduced duration and severity of cold symptoms. We related the improvement in cold symptoms to the antioxidant and anti-inflammatory properties of zinc.

The Impact of Zinc Supplementation on Left Ventricular Function in Nonischemic Cardiomyopathy [Completed]
Heart failure affects over 5. 3 million Americans and, while other cardiovascular diseases have enjoyed a reduction in mortality rates over the last decade, the mortality from heart failure continues to rise[1]. Thus, identifying novel therapies that can reduce heart failure development and/or progression are warranted. Unifying to most cardiomyopathic processes is an impaired handling of reactive oxygen species (ROS)[2-4]. Reactive oxygen species are generated as byproducts of inflammation and oxidative stress that occur in the setting of normal myocardial aerobic metabolism. Metallothionein, glutathione reductase, and superoxide dismutase are major antioxidants in the myocardium that help combat oxidative stress and prevent myocardial damage. In certain clinical settings, including cardiac ischemia, diabetes, and heavy metal excess (copper, iron), myocardial oxidative stress levels are greatly increased. When pro-oxidant levels exceed myocardial antioxidant capabilities, ROS-induced membrane, protein, and DNA inactivation can lead to the development of cardiac dysfunction. One means of preventing the development or progression of cardiomyopathy is to reduce oxidative stress through up-regulation of intramyocardial antioxidants. Murine studies of cardiomyopathy have shown that oral administration of zinc acetate may succeed as an indirect myocardial anti-oxidant because zinc sufficiently up-regulates the intramyocardial production of superoxide dismutase (a zinc-dependant anti-oxidant enzyme) and metallothionein (a "super antioxidant") [5-8]. Zinc also directly reduces prooxidant Cu levels by reducing gastrointestinal zinc absorption. However, to date, no studies have examined the impact of zinc acetate supplementation in subjects with cardiomyopathy and systolic failure on antioxidant capacity and remodeling. The hypothesis of this pilot study is that administration of oral zinc acetate to humans with cardiomyopathy will lead to an up-regulation of myocardial anti-oxidant capabilities,leading to a favorable reduction in oxidative stress. This study will provide preliminary data to support a randomized, placebo-controlled trial of zinc therapy in heart failure as a means of improving or preventing the progression of systolic dysfunction in subjects with mild-moderate heart failure.

Zinc Homeostasis and Kinetics in Children With Cystic Fibrosis (CF) [Completed]
Zinc deficiency has occasionally been reported in CF, but the need for additional zinc is unclear. We will examine the effect of additional zinc supplements on zinc absorption, zinc excretion, zinc balance and zinc kinetics in children with CF. Twelve children with CF will receive additional zinc, and twelve will not. We will also compare the children with CF to 12 healthy children without CF. We hypothesize that children with CF will have poor zinc absorption and high zinc excretion, leading to poor zinc balance and abnormal zinc kinetics. We hypothesize that those children with CF who are given zinc supplements will have higher zinc balance and more normal zinc kinetics than those without supplementation, and that zinc balance and zinc kinetics will be similar to healthy children.

Safety, Pharmacokinetics and Acceptability of PC-1005 for Vaginal Use [Active, not recruiting]
This Phase 1 clinical trial will evaluate MIV-150, a third generation non-nucleoside reverse transcriptase inhibitor, co-formulated with a potentially potent agent, zinc acetate for the prevention of HIV infection in women. This is the first in-human of PC-1005 (MIV-150/zinc acetate in a carrageenan gel), the first study in which females will be exposed to MIV-150, the first time MIV-150 will be administered topically, and the first time MIV-150 will be administered intravaginally.
