Priadel is a medication primarily used in the treatment of bipolar disorder, a condition characterized by episodes of depression and mania. It contains lithium carbonate as its active ingredient, which helps to stabilize mood and reduce the severity and frequency of mood swings. Priadel works by affecting the flow of sodium through nerve and muscle cells in the body, which helps to control the manic and depressive symptoms associated with bipolar disorder. It may also be prescribed for other conditions as determined by a healthcare provider. Patients taking Priadel require regular monitoring of their lithium blood levels to ensure the medication is effective and to prevent potential side effects, such as lithium toxicity.
