What is a common form of lithium prescribed for treatment?

Lithium is frequently prescribed for the treatment of mood disorders, particularly bipolar disorder, due to its mood-stabilizing properties. Eskalith, which is a brand name for lithium carbonate, is one of the most common formulations used in clinical practice. This medication works by affecting neurotransmitter release and the activity of certain ions in the brain, leading to improved mood stabilization and reduced episodes of mania or depression.

The other options refer to different medications that are not lithium. Neurontin, or gabapentin, is primarily used for neuropathic pain and seizures, while Lithobid is a formulation of lithium but also it is a brand name for lithium carbonate similar to Eskalith. Depakote and lamotrigine are medications used in the treatment of epilepsy and mood disorders, but they have different mechanisms of action than lithium and are not considered forms of lithium. Therefore, Eskalith as lithium carbonate is the correct and commonly prescribed form of lithium for treating mood disorders.
