Differences in High Dose Antipsychotic Prescriptions in Patients with Schizophrenia in Asian Countries/Areas: Findings from the REAP-AP Study

Abstract

The REAP-AP study recruited 3,746 patients with schizophrenia, in March and April 2016, from 71 centers in 15 Asian countries/territories namely Bangladesh, China, Hong Kong, India, Indonesia, Japan, Korea, Malaysia, Myanmar, Pakistan, Singapore, Sri Lanka, Taiwan, Thailand and Vietnam. Our findings reveal a trend according to which high dose antipsychotic prescription is more prevalent in Eastern Asia (especially, Japan and Korea) than in other regions of Asia. This historical factor may be associated with our finding of an Eastern Asian preponderance of high dose antipsychotic prescription.
