Regarding the subtypes of lithium intoxication, there are acute, acute-on-chronic and chronic forms, which differ in their symptomatology due to lithium pharmacokinetics. Lithium pharmacokinetics can be divided into absorption, distribution and elimination phases (Jaeger et al. Lithium is an alkali metal, like potassium and sodium, which facilitates its rapid distribution (Young 2009). Since lithium is one of the lightest elements of the periodic table, it is easily distributed throughout total body water (Young 2009 Perrone 2015). The effective dose range of lithium is 0.6–1.0 mmol/l, while in prolonged administration it may be toxic at 1.2 mmol/l or greater (Young 2009).
In addition, lithium has been shown efficacious in augmenting response in antidepressant non-responders and in severe treatment-resistant unipolar major depression (Haussmann and Bauer 2013).ĭue to a relatively narrow therapeutic index, lithium intoxication has been a common clinical problem (Timmer and Sands 1999 Hampton 2014).

Since 1970, lithium has been approved and widely used as the gold standard for the treatment of acute episodes and maintenance treatment of bipolar disorder (Nolen 2015 Severus et al.
