The long-term treatment of periodical and cyclic depressions with flupenthixol decanoate.

In a 2- to 3-year open study 30 patients were treated with flupenthixol decanoate (depot form). These periodic and cyclic depressive patients had side effects during treatment with lithium salts. In comparison with the depressive and manic phases before the treatment, the prophylactic effect of flupenthixol decanoate on periodic and cyclic forms of depression was similar to the effect of lithium salts.
