A double-blind randomized investigation compared withdrawal (placebo) with continued use of long-acting neuroleptics (fluphenazine decanoate or flupenthixol decanoate) in 41 chronic schizophrenic outpatients. After 6 weeks there was a tendency toward higher depressive scores in the placebo group, a difference which became statistically significant (p less than .05) at week 24. These results do not support earlier observations that neuroleptic drugs cause depression. Further analyses of the data indicated that depressive symptomatology could be an early sign of relapse.

Sixty-eight depressed out-patients were allocated to treatment with either oral amitriptyline (75-225 mg/day) or intramuscular flupenthixol decanoate (10-30 mg every 14 days) in flexible dosage for 12 weeks under double-blind procedures. Various observer- and self-rating scales were applied before and after 2, 4, 8 and 12 weeks of treatment. Twenty-four patients completed the course of amitriptyline and 20 the course of flupenthixol. All variables improved over time, but there were no significant differences between the two drugs. The Newcastle scores pre-treatment were not related to drug response suggesting that both drugs were similarly effective across a wide spectrum of depressive disorders. Patients on amitriptyline tended to complain of dry mouth; those on flupenthixol had a higher incidence of extrapyramidal signs, the majority receiving anti-parkinsonian drugs at some time during the treatment. Flupenthixol decanoate in low dose is a useful anti-depressant, but should be restricted to short courses of treatment, to patients refractory to other treatments, and to patients suspected of poor compliance.

The hypothesis that flupenthixol decanoate may serve as an alternative to prophylactically administered lithium in recurrent manic-depressive illness, bipolar and unipolar type, was tested in two groups of patients. In Group I the patients were allocated randomly to maintenance treatment with either lithium or flupenthixol decanoate. The patients in Group II had previously been given lithium and were switched to flupenthixol decanoate because of unsatisfactory prophylactic effect of lithium, doubtful tablet compliance, troublesome side effects, or fear of later harmful effects. The flupenthixol decanoate dosage was 20 mg every 2-3 weeks. The study was not blind. In Group I neither lithium treatment (14 patients) nor treatment with flupenthixol decanoate (19 patients) led to a significant fall of mean episode frequency or mean per cent time ill. The reasons for this lack of response are not clear, but prognostically negative selection of the patients presumably took place before and possibly also during the hospitalization. Since absent effects cannot be compared, this part of the trial remains inconclusive. In Group II (93 patients) treatment with flupenthixol decanoate was associated with significant falls of the frequency of manic episodes and per cent time ill in mania and with significant rises of the frequency of depressive episodes and per cent time ill in depression. Increase of depressive morbidity was seen only in patients who had been given lithium during the pre-trial period and was presumably a result of the discontinuation of lithium. It is not known whether flupenthixol decanoate is of value in the prophylactic treatment of recurrent manic-depressive illness, but the drug may be worth trying in patients whose disease is dominated more by manic than by depressive recurrences and who do not respond to lithium or do not tolerate it or do not take it.

There are no data available on the risk of extrapyramidal symptoms when using long-term flupenthixol in low dosage in patients suffering from anxiety and depressive disorders. In a case control study 106 patients essentially treated with the neuroleptic flupenthixol in a so-called low, non-antipsychotic dosage were compared to n=37 otherwise comparable patients who never had been treated with neuroleptics. The investigator was blind to the previous treatment conditions. Extrapyramidal symptoms were found although with a low prevalence and mild degree: 6.7% tardive dyskinesia, none in controls; pseudoparkinsonism 26%, 16% in controls. Extrapyramidal side-effects, especially tardive dyskinesia, have to be considered in the individual weighing of therapeutic benefits and risks even when prescribing flupenthixol in low dosages.

Doctors' prescription and dosing behaviour was investigated using data from 9 clinical trials in 550 patients treated with psychotropics. 7 trials were conducted under double- and 2 under single-blind conditions. In 3 of these trials, oral and i.m. preparations were used demanding a double-dummy design. All patients were evaluated on a weekly or 2-week basis using psychopathological rating scales (i.e. Hamilton Anxiety Scale, Hamilton Depression Scale, Clinical Global Impressions, Simpson and Angus EPS). It was found that (a) oral-medication titration was 3- to 4-fold more broad-ranging than i.m. medication titration, (b) oral placebo was titrated to the same extent as the oral investigational drugs, and (c) the titration schedule did not follow protocol requirements. Moreover, the average doses in all drug and placebo groups were the same. Concomitant medication like sleep inducers was found to be more closely related to doctors' habits than to actual medical need. Independent of trial and investigational drug, 10-33% of all patients received additional sleep inducers.

Two cases of agranulocytosis occurring after addition of a butyrophenone to a course of phenothiazine treatment are reported and possible mechanisms for this interaction are discussed.

The antidepressive and anxiolytic efficacy of flupenthixol has been investigated in numerous controlled and open trials involving patients with endogenous, reactive as well as senile depressions. When administered at a mean daily single or multiple dose of 1-2 mg, flupenthixol proved to be a very effective and well-tolerated antidepressant. As opposed to some of the currently available antidepressants, flupenthixol has a rapid onset of action which is often displayed within the first 2-3 days following its application. Flupenthixol decanoate has also a pronounced antidepressive and anxiolytic effect which appears to be adequate enough for treating mild to moderately severe syndromes of depression. This depot neuroleptic has been given at a fortnightly dosage ranging between 2.5 and 30 mg. However, if the aspect of efficacy in relation to tolerance has to be taken in to consideration, then 5 mg are apt to be an appropriate dose. Patients with an agitated depression and/or suicide ideation should, however, be excluded from therapy with this drug. Extrapyramidal movement disorders which may appear during treatment are a disadvantage of this medication. Apparently such disorders are rarely encountered if the dose is kept below 10 mg. Other untoward effects are very seldom indeed. A final and conclusive judgement on the possible application of flupenthixol decanoate in the prophylaxis of phases in patients with bipolar and periodical depressions is as yet not feasible. Further clinical trials are necessary before flupenthixol decanoate can be classified as a possible 'depot antidepressant'.
