Abstract

The objective of this study was to assess the efficacy and tolerability of minocycline add-on to risperidone in treatment of negative symptoms of patients with chronic schizophrenia. In a randomized double-blind placebo-controlled study, 40 patients with chronic schizophrenia who were stabilized on risperidone for a minimum duration of eight weeks were recruited. The patients were randomly assigned to minocycline (titrated up to 200 mg/day) or placebo in addition to risperidone (maximum dose of 6 mg/day) for eight weeks. Positive and Negative Syndrome Scale (PANSS), Hamilton Depression Rating Scale, and Extrapyramidal Syndrome Rating Scale were used. Thirty-eight patients completed the study. Significant time × treatment interaction for negative [F(2.254,85.638)=59.046, P<0.001] general psychopathology [F(1.703,64.700)=6.819, P=0.001], and positive subscales [F(1.655,62.878)=5.193, P=0.012] as well as total PANSS scores [F(1.677,63.720)=28.420, P<0.001] were observed. The strongest predictors for change in negative symptoms were the treatment group (β=-0.94, t=-10.59, P<0.001) followed by the change in PANSS positive subscale (β=-0.185, t=-2.075, P=0.045). Side effect profiles of the two treatment regimens were not significantly different. Minocycline seems to be an efficacious and tolerable short-term add-on to risperidone for treatment of negative and general psychopathology symptoms of schizophrenia.

  • Clinical trials using minocycline alone or as an adjunct to risperidone in patients with schizophrenia have demonstrated overall improvement in negative symptoms and executive functioning.

    “Various clinical trials have been conducted using minocycline alone or as an adjunct to risperidone in patients with schizophrenia and have demonstrated overall improvement in negative symptoms and executive functioning (Miyaoka et al., 2008; Levkovitz et al., 2010; Khodaie-Ardakani et al., 2014).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
