Influence of naproxen on the zinc, copper, magnesium and calcium content of guinea pig tissues.
The effect of the administration of chronic doses of naproxen on the zinc, copper, magnesium and calcium concentrations in guinea pig tissues was studied. One hundred mg naproxen/kg body weight/week were administered intraperitoneally to adult female guinea pigs in two doses twice a week for eight weeks. A statistically significant decrease was found of the zinc content in the brain, lung, heart, liver, kidney, spleen and adrenals, of the copper content in the liver, kidney and adrenal and of the magnesium content in the spleen and heart. A significant increase was observed of the calcium content in the adrenals, heart, spleen and uterus of the treated animals, while no significant changes were observed in the thigh bone concentrations of the various ions tested.
