SummaryIn this double-blind, four-week study, 28 chronic schizophrenic patients receiving neuroleptic medication plus the antiparkinsonian drug, benztropine mesylate, were either switched to placebo or maintained on benztropine. Patients withdrawn from benztropine reliably increased their overall scores on the Wechsler Memory Scale in comparison with the drug group. Sub-test scores suggest that deficits in attention and concentration were induced by treatment with benztropine. Psychotio decompensation appeared to develop simultaneously with extrapyramidal symptoms (EPS) in some patients, but only 14.2 per cent of the placebo group experienced extrapyramidal symptoms severe enough to require resumption of benztropine therapy. It is suggested that antiparkinsonian agents should be prescribed only if and when EPS occur.

With Memory

BackgroundThe effects on memory of an anticholinergic (biperiden) and a dopaminergic (amantadine) anti-Parkinsonian agent were compared.MethodTwenty-six chronically medicated schizophrenic (DSM–III–R) in-patients received amantadine (200 mg/day) or biperiden (4 mg/day) for two weeks in a double-blind cross-over design.ResultsBiperiden treatment was associated with significantly lower scores on Benton Visual Retention Test (P< 0.003) and the visual subscale of Wechsler Memory Scale (WMS) (P≤ 0.02), with a trend to poorer scores on WMS total (P= 0.086) and the digit span (P= 0.07) and logical memory (P= 0.06) subscales.ConclusionsIn usual clinical doses, biperiden interferes with memory, particularly visual, more than amantadine.

Schizophrenic Patients

A double-blind comparative trial of loxapine and trifluoperazine was carried out in 57 acute and chronic schizophrenic patients. In both groups of patients loxapine proved to be equivalent in its effects to trifluoperazine and there were suggestions it might be rather more effective in chronic patients. Side-effects were simitar with the two drugs but anticholinergic effects, excitement, dizziness and faintness occurred rather more commonly with loxapine. Laboratory tests, urine analysis, cardiovascular and ophthalmological investigations showed no significant abnormalities.

SummaryA double blind, placebo controlled trial was carried out to examine the contribution of propranolol as an adjunct to neuroleptic medication in the treatment of chronic schizophrenic patients whose florid symptoms had not remitted with neuroleptic medication alone. Propranolol was shown to have a more beneficial effect than placebo, but the results were much less dramatic than those which have been described in previous studies. Recent work has shown that there may be a pharmacokinetic interaction between propranolol and neuroleptics, and this should be considered as one possible explanation of our findings.
