A recent research conducted by Stefan et al and published in The Lancet, systematically reviewed the efficacy of antipsychotic drugs in preventing relapses in patients with schizophrenia, when compared to placebo. The review included 116 reports from about 65 clinical trials published over the past 50 years. Only those trials were taken into account where schizophrenic patients became stabilized after seeking treatment.
Reports from the Cochrane Schizophrenia Group's specialized register, Embase, PubMed and ClinicalTrials.gov were analyzed.
AdvertisementThe researchers observed that there was a marked decrease in relapse rates at one year in patients treated with antipsychotic drugs. The number of patients requiring re-admission with antipsychotic drugs was quite less than those with placebo.
The injectable antipsychotic drugs reduced the relapsing of schizophrenia more than the oral drugs.
Some adverse effects reported include, movement disorders increased sedation and weight gain in patients on antipsychotic drugs.
The researchers finally stated that the benefits of antipsychotic drugs should be contrasted against the adverse effects produced by them. They further added that more researches are required to elucidate the long-term mortality and morbidity of antipsychotic drugs.
