RESUMO
Background: There is great controversy about role of male sex steroid, testosterone, in mental disorders like schizophrenia. This study assessed the effectiveness of testosterone in schizophrenic patients and probes how it modulates the action of combination of first and second generation anti-psychotic medications (Chlorpromazine + Risperidone) both of which are very commonly used anti-psychotic agents in clinical psychiatric practice.Methods: It Is randomized, double-blind, Clinical study performed in Indian schizophrenic patients (new cases) in the Department of psychiatry from Feb 2003 to March 2004. Patients twelve (12) patients aged 20 to 60 years diagnosed schizophrenics according to ICD-10 Criteria who visited in outpatient department of psychiatry during study period. 12 Patient was treated with combination of oral Chlorpromazine 200mg BD + oral Risperidone 2mg BD, half of the 12 patients also received single dose of testosterone 100mg intramuscularly with above-mentioned treatment. Measure How symptomatology in schizophrenic patients affected is measured by applying various validated psychiatric scales like Brief psychiatric Rating Score (BPRS), Scale for assessment of positive symptom(SAPS), and Scale for Assessment of Negative Symptoms (SANS).Results: Single dose of Testosterone 100mg administered initially by I.M. route potentiated the reduction level in negative symptoms of schizophrenia by 119% in patients receiving oral Chlorpromazine 200mg along with oral Risperidone 4mg/day.Conclusions: In this study, Testosterone potentiated the effects of combination of oral Chlorpromazine 100mg BD + Risperidone 2mg BD, on general psychotic manifestations, positive symptoms and negative symptoms of schizophrenia, assessed on BPRS, SAPS and SANS scoring scales, however the effect is most pronounced in negative symptomology of schizophrenia.
RESUMO
Background: This study evaluates and compares how negative and positive symptoms of schizophrenia were influenced with monotherapy with a first-generation anti-psychotic medication (Chlorpromazine) and a second generation anti-psychotic medication (Risperidone) and by their combination, both of which are commonly used in clinical psychiatric practice.Methods: It was randomized, double-blind, controlled clinical study performed in Indian newly diagnosed schizophrenic patients in the Department of psychiatry from Feb 2003 to March 2004. Patients 18 (eighteen) patients aged 20 to 60 years diagnosed schizophrenics according to ICD-10 Criteria who visited in outpatient department of psychiatry during study period. Three groups of 6 Patient each, group-1 - was treated with oral Chlorpromazine 100 mg 12 hly, group -2 - was treated with oral Risperidone 2mg 12 hly group 3 -was treated with combination of oral Chlorpromazine 100mg 12 hly + oral Risperidone 2 mg 12 hly. How symptomatology in schizophrenic patients affected, is measured by applying various validated psychiatric scales like Brief psychiatric Rating Score (BPRS), Scale for assessment of positive symptom(SAPS), and Scale for Assessment of Negative Symptoms (SANS).Results: the study showed that the combination therapy of oral Chlorpromazine 100 mg 12 hly + Risperidone 2mg 12 hly had reduced the overall beneficial effects which were achieved with monotherapy of both the drugs.Conclusions: In this study, the therapeutic effects of combination of oral Chlorpromazine 100 mg 12 hly + Risperidone 2 mg 12 hly found to be reduced on positive symptoms and negative symptoms of schizophrenia, assessed on SAPS and SANS scoring scales when compared with beneficial effects which were achieved with monotherapy of both the drugs.
