Lithium maintenance treatment of manic-melancholic patients: its role in the daily routine.

The purpose of this study was to evaluate the desired and undesired effects of relapse-preventive lithium treatment given routinely to manic-melancholic patients who had accepted the necessity of a strict tablet regime. The evaluation was based upon case record data and various rating scales, and 76 patients took part in the investigation. Our results showed that in 24% of the patients treatment was discontinued. This was due to side effects in 16% and to insufficient effect in 8% of the cases. The suicide risk was not eliminated, and 29% of the patients were receiving additional antidepressive or antimanic treatment at the test day. On the other hand, 78% of the patients rated the relapse-preventive lithium effect as moderate to excellent. Indirect evidence was obtained in support of a stabilizing effect of lithium on the emotional control in bipolar patients. The most frequent complaints during lithium treatment were tremor and increased thirst.
