- Toxicity
- 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.
Use
Lithium has numerous industrial applications. It is used to make highenergy lithium batteries. Lithium and its aluminum alloys are used as anodes in non-aqueous solid-state batteries. Also, many of its salts are used as electrolytes in these batteries. Another major application is in metallurgy. Lithium is alloyed with lead, magnesium, aluminum and other metals. Its alloy Bahnmetall is used for wheel bearings in railroad cars, and its magnesium alloy is used in aerospace vehicles. Probably the most important applications of lithium are in preparative chemistry. It is the starting material to prepare lithium hydride, amide, nitride, alkyls and aryls. Lithium hydrides are effective reducing agents. The alkyls are used in organic syntheses.
