Efficacy and Effectiveness of Lithium in the Long-Term Treatment of Bipolar Disorders: An Update 2018.

For more than 40 years, lithium has been the gold standard in the long-term treatment of bipolar disorders. In the course of the last 15 years, other drugs have been approved in this indication and are widely used in clinical practice at the expense of lithium. New research from the last few years, however, indicates that lithium is still the first-line treatment in this indication. Against this background and lithium's proven acute antimanic efficacy, we should perhaps be using lithium more regularly (in combination with an atypical antipsychotic, if necessary) right from the start for the acute treatment of a manic episode and, once remission has been achieved and euthymia maintained during continuation treatment, to regularly taper off the atypical antipsychotic, if possible, and continue with lithium as monotherapy for prophylactic treatment. This might lead to lithium being used more consistently with the scientific evidence in the long-term treatment of bipolar disorders. It remains uncertain, however, to predict who will respond to and tolerate lithium prophylactically, and more research is needed to deliver the best possible individualized care to our patients. © Georg Thieme Verlag KG Stuttgart · New York.
