The Side Effect of Haloperidol in Schizophrenic Patients: Analysis of Red Blood Cell Distribution Width (RDW) and Mean Platelet Volume (MPV) Values

INTRODUCTION: Like the increase of pro-inflammatory cytokines and oxidative stress as schizophrenia pathophysiology, haloperidol also increases RDW and MPV values. Both of these values ​​have been clinicians concern because they are a risk factor for the various type of vascular disease.

OBJECTIVE: This study aims to determine the side effect of haloperidol on RDW and MPV values in schizophrenic patients.

METHODS: This research method uses observational analytic design with a prospective cohort approach with pre and posts analysis conducted at the Regional Special Hospital of South Sulawesi Province during May - July 2018 in 30 schizophrenic subjects. The subjects were diagnosed as first episode schizophrenia based on ICD 10, blood samples were taken, for RDW and MPV values ​​before and after haloperidol was given at the 4th and 8th weeks.

RESULTS: The results showed that the mean RDW value at the 4th week was higher in 15 mg/day haloperidol group (15.8) compared to 7.5 mg/day haloperidol group (15.3) with p<0.05. Mean RDW value taken at 8th week was higher in 15 mg/day haloperidol group (16.4) compared to 7.5 mg/day haloperidol group (15.6) with p<0.001. Mean MPV value taken at 8th week was higher in 15 mg/day haloperidol group (13.3) compared to 7.5 mg/day haloperidol group (11.6) with p<0.001.

CONCLUSION: This study showed an increase in the RDW value in schizophrenia subjects prior to the haloperidol administration. RDW ​​and MPV values were higher after haloperidol treatment compares to before haloperidol treatment. The increase of RDW and MPV values tend to be influenced by haloperidol dosage and administration duration.
