Using positron emission tomography and the selective ligands 11C-SCH23390 and 11C-raclopride, central D1- and D2-dopamine receptor occupancy was determined in schizophrenic patients treated with clinical doses of classical and atypical neuroleptics. Treatment with ten chemically distinct classical neuroleptics resulted in a 65–89% occupancy of D2-dopamine(More)
Subsidiary findings in several studies indicate that the standard summary scores (total number of needs, met needs and unmet needs) of the Camberwell Assessment of Need (CAN) may conceal important differences among patient populations at the item level of the measure. The aim of this study was to investigate whether changes in need and need status at the(More)
BACKGROUND In order to define needs for care of people with severe mental illness, the Camberwell Assessment of Need (CAN) is focused on measuring personal and social functioning. However, previous studies of the CAN have given inconsistent results in terms of what variables are actually being measured. AIMS To investigate the factor structure of the CAN.(More)
A mass fragmentographic method for the quantification of clomipramine (CIM) and monodemethyl-clomipramine (DCIM) in human plasma was developed. The deuterium labelled analogues of the compounds were used as internal standards. The sensitivity of the method allows the determination of CIM and DCIM in plasma after oral doses with a standard deviation less(More)
The effect of the selective serotonin-2 antagonist ritanserin was investigated in an open study of patients with schizophrenia. The patients were in an acute psychotic state considered to require neuroleptic medication. No neuroleptic drug was allowed during the study or during the last month preceeding the study. Oxazepam or nitrazepam were allowed for(More)
Six female and six male healthy volunteers received 100 mg remoxipride, 200 mg sulpiride and placebo as single oral doses in a double blind trial with a randomized crossover design. The main objective was to compare the effect of the two drugs on serum prolactin levels, but effects on other hormones were also investigated. Remoxipride and sulpiride(More)
Citalopram is a bicyclic phtalane derivative. In animal experiments, citalopram has been demonstrated to possess a potent and highly selective inhibitory effect on serotonin reuptake. Several studies in man have indicated that citalopram given in daily doses of 40–60 mg has antidepressant properties and few side effects. The present double-blind study(More)
A mass fragmentographic method for the simultaneous determination of 4-hydroxy-3-methoxyphenylacetic acid (HVA), 4-hydroxy-3-methoxyphenylethylene glycol (MOPEG), and 5-hydroxyindole-3-acetic acid (5-HIAA) was described. Deuterated analogues of the compounds were used as internal standards. The specificity was proved by multiple ion analysis. The(More)
Sulpiride (100 mg) was administered intravenously and orally to healthy human subjects. Serum concentrations of sulpiride and prolactin were followed for 36 h. Both routes of drug administration resulted in a pronounced and sustained increase in serum prolactin concentration. The prolactin response was positively correlated to the prolactin baseline value.(More)
Chlorpromazine (CPZ), demethylated(nor1)-CPZ, 7-hydroxy(7-OH)-CPZ, and CPZ-nitrogenoxide-(NO) were administered to rats. Levels of homovanillic acid (HVA), 5-hydroxyindoleacetic acid (5-HIAA), and 3-methoxy-4-hydroxyphenylglycol (MOPEG) in the brain and prolactin in serum were determined. The HVA increase calculated per nmole unchanged drug in brain was(More)
