Lithium pharmacology - Wikipedia, the free encyclopediaThis article discusses the pharmacological uses of lithium salts; for information on the chemistry of individual lithium salts, see Category:Lithium compounds., as a drug. A number of chemical salts of lithium are used medically as a mood stabilizing drug, primarily in the treatment of bipolar disorder, where they have a role in the treatment of depression and particularly of mania, both acutely and in the long term. As a mood stabilizer, lithium is probably more effective in preventing mania than depression, and may reduce the risk of suicide.The use of lithium salts to treat mania was rediscovered by the Australian psychiatrist John Cade in 1949. Cade was injecting rodents with urine extracts taken from schizophrenic patients, in an attempt to isolate a metabolic compound which might be causing mental symptoms. Since uric acid in gout was known to be psychoactive (adenosine receptors on neurons are stimulated by it, as with caffeine), Cade needed soluble urate for a control. He used lithium urate, already known to be the most soluble urate compound, and observed that this caused the rodents to be tranquilized. Cade traced the effect to the lithium ion itself. Soon, Cade proposed lithium salts as tranquilizers, and soon succeeded in controlling mania in chronically hospitalized patients with them. This was one of the first successful applications of a drug to treat mental illness, and it opened the door for the development of medicines for other mental problems in the next decades.Eskalith (Lithium Carbonate) Drug Information: Uses, Side Effects, Drug Interactions and Warnings at RxListLithium toxicity is closely related to serum lithium levels, and can occur at doses close to therapeutic levels.
