A double-blind withdrawal trial in 41 chronic schizophrenic outpatients was carried out during 6 months. Depot neuroleptics (fluphenazine decanoate or flupenthixol decanoate) were compared with placebo to evaluate clinical and neurological effects during continued therapy and during withdrawal. The drugs were significantly more effective than placebo in(More)
Of all known schizophrenics living in Nithsdale, south-west Scotland, 146 (88%) were examined for the presence of the three principal movement disorders secondary to antipsychotic medication, namely akathisia, tardive dyskinesia and Parkinsonism. Of these, 18% had akathisia, 5% pseudoakathisia, 29% tardive dyskinesia, 8% persistent tardive dyskinesia, and(More)
The plasma prolactin (PRL) response to haloperidol 2 or 4 mg i.m. was studied in 18 schizophrenic men during their routine treatment with neuroleptic drugs. A substantial rise of the PRL level above the treatment baseline occurred in all but four of the 20 tests showing that the PRL elevation induced by treatment was not maximal. The challenge was(More)
Seventeen acute psychotic patients were studied in the course of chlorpromazine (CPZ) treatment. Blood samples were taken weekly both before and two hours after the morning CPZ dose. Plasma levels of CPZ, CPZ sulphoxide (CPZ SO) monodesmethylated CPZ (NOR1CPZ) and 7-hydroxy CPZ (7OH CPZ) were estimated by gas chromatography. Plasma prolactin, luteinizing(More)
In a double-blind comparison of haloperidol decanoate and fluphenazine decanoate given 4-weekly for 60 weeks as maintenance therapy in 38 chronic schizophrenic in-patients, plasma haloperidol, fluphenazine and prolactin levels were measured at regular intervals by radioimmunoassay. After the first injection, the mean plasma haloperidol level was highest at(More)
1 Using a radioimmunoassay, plasma fluphenazine (FPZ) concentrations were examined in 33 schizophrenic patients during 38 intervals between injections of FPZ decanoate. Doses ranged from 12.5 to 150 mg and intervals from 1 to 5 weeks. At least three blood samples were taken between injections from each subject; also in 26 subjects additional samples were(More)
Of 49 schizophrenic patients followed up 2 years after their first admission to hospital, 37% were well, 47% had been readmitted to hospital at some time over the 2 years, and 38% showed schizophrenic symptoms at follow-up. A poor outcome at 2 years was associated with male sex, poor outcome after the first 5 weeks of the first admission, negative(More)
AIMS To determine serum salicylic acid concentrations in non-vegetarians and vegetarians not taking salicylate drugs, and to compare these concentrations with those found in patients taking aspirin, 75 mg daily. METHODS Serum samples were obtained from vegetarians (n = 37) and non-vegetarians (n = 39) not taking salicylate drugs. Non-vegetarians and(More)
