Eskalith
® (
lithium carbonate) is a prescription medication approved to treat
bipolar disorder, a mental illness also known as
manic depression. Eskalith CR
® is an extended-release version of Eskalith and is also approved to treat
bipolar disorder.
Eskalith and Eskalith CR were originally made by GlaxoSmithKline. However, GlaxoSmithKline has stopped making these products. Fortunately, generic versions of Eskalith and Eskalith CR are available.
Lithium (the active ingredient of Eskalith and Eskalith CR) is a naturally occurring element, like iron, sodium, or calcium. In the 1800s, scientists thought that lithium might work for treating gout, although it was found to be ineffective for this use. Later, in the 1940s, lithium was used as a salt substitute, until it was withdrawn from the market due to several deaths caused by
lithium toxicity. Later, it was discovered that the drug works for mania. In 1970, the U.S. Food and Drug Administration (FDA) approved lithium for treating bipolar disorder.
The exact way in which Eskalith works to treat bipolar disorder is not known. It is thought that the drug may affect various chemicals in the brain called neurotransmitters, which could explain the effectiveness of Eskalith for treating bipolar disorder. Eskalith is not a cure for bipolar disorder, however. It only helps to control symptoms
(see Bipolar Disorder Symptoms).
Eskalith CR was designed to help keep a steady level of lithium in the blood. It releases a portion of the dose initially, and then gradually releases the rest of the dose slowly over time.
