Giftige Stoffe Daten 7439-93-2(Hazardous Substances Data)
Toxizität An element used clinically as one of its salts. It is effective against both mania and depression. Despite its effectiveness, there are no clear mechanisms that have been directly related to its therapeutic effectiveness although its inhibition of the formation of inositol from inositol phosphate is thought to be important. At therapeutic concentrations, lithium causes almost no discernible psychotropic effects in healthy humans. The major complaints when the serum concentrations of the drug are carefully monitored include slight muscular weakness, thirst, and excessive urination. The major difficulty with lithium is that a fairly high concentration of the ion is needed in the blood (0.5_x0002_1.0 mmol/L) for maintenance, higher for acute mania. Toxic symptoms (which can involve many physiological symptoms) may occur, however, at doses of 1.5 mmol/L or higher. This low therapeutic index is indicative of the need for regular monitoring of lithium concentrations in the serum.
