LITHIUM CARBONATE

inorganic compound that is the primary treatment for manic depression. Lithium is highly effective in dissipating a manic episode and in calming the patient, although its action in this regard may take several weeks. When given on a long-term maintenance basis, lithium can prevent both manic and depressive mood swings or can drastically reduce their severity. It can also suppress the psychotic features sometimes exhibited in manic-depressive patients. The drug's mode of action is unknown. Side effects of its use include increased urination, tremors, diarrhea, nausea, drowsiness, and, at higher concentrations, convulsions, coma, and death.
