Adverse Effects of Medication and Quality of Life in Patients Receiving Second Generation Antipsychotics: A Comparison of Long Acting Injectable and Oral Therapies

Abstract

Maintenance treatment with antipsychotic drugs for patients with schizophrenia is highly effective in decreasing the recurrence rate of the disease. In the current study, we aimed to compare long-acting second generation antipsychotic drug injections and oral forms of second generation antipsychotic drugs in terms of their adverse effects on quality of life. Forty-one patients receiving second generation antipsychotic drugs and 139 patients diagnosed with schizophrenia or schizoaffective disorder were treated with oral second generation antipsychotic drugs and enrolled in the study. All patients were evaluated with Positive and Negative Symptoms Scale (PANNS), extrapyramidal symptom rating scale (ESRS) and UKU, and Quality of Life Enjoyment and Satisfaction questionnaire (Q-LES-Q). The impact of adverse effects of oral second generation antipsychotic drugs on the daily performance of patients with schizophrenia or schizoaffective disorder was found to be significantly higher than that of the long acting injection antipsychotic drugs. The quality of life of patients receiving long acting second generation antipsychotic drug injection was significantly higher when compared with that of the patients treated with oral second generation antipsychotic drugs. The results of this study showed that the long-acting second generation antipsychotic injection treatment was superior to second generation oral forms of antipsychotic drugs in terms of adverse effects and measures of quality of life. Further studies with specific design and the supplementation of larger samples are needed.
