lithium carbonate a psychotropic drug used to treat acute manic attacks in bipolar disorder and, when given on a maintenance basis, to prevent the recurrence of manic-depressive episodes. The desired serum levels are in the range 0.5–1.5 mEq/L. Life-threatening central nervous system effects and kidney damage occur at levels above 3.0 mEq/L. It is very important that the levels be carefully controlled. Lithium should not be given to patients with severe renal or cardiovascular disease or taken with diuretics because the potential for toxicity is very high. It is suspected of causing birth defects and should not be used during pregnancy.
lithium citrate the citrate salt of lithium, having the same actions and uses as the carbonate salt.
