หน่วยบริการการศึกษาชีวสมมูลของผลิตภัณฑ์ยา (Bioequivalence Unit)
เป็นหน่วยงานที่จัดตั้งขึ้นเพื่อให้บริการศึกษาชีวสมมูลของผลิตภัณฑ์ยาแก่หน่วยงานภายนอกทั้งภาครัฐและเอกชน โดยที่หน่วยงานนี้อยู่ภายใต้การกำกับดูแลของภาควิชาเภสัชวิทยา คณะแพทยศาสตร์ มหาวิทยาลัยขอนแก่น การดำเนินการและการบริหาร จะกระทำตามหลักวิชาการ โดยไม่มีผลประโยชน์ร่วมใดๆกับผู้รับบริการ โดยที่ทางหน่วยได้เปิดให้บริการการศึกษาชีวสมมูลมาตั้งแต่ปี 2543 และมีความมุ่งมั่นที่จะพัฒนางานให้มีคุณภาพตามระดับมาตราฐานสากล
Background
BEU is a clinical trial & research unit under the Department of Pharmacology, Faculty of Medicine, Khon Kaen University, Thailand. It was founded in 2000 and has been rapidly facilitated for the demand in clinical trials and researches, in the faculty of Medicine. The unit has been well organized to support clinical conduct particularly in drug bioequivalence. All clinical protocols here are submitted to the Ethics Committee for Human Research, Khon Kaen University, to provide ethical confidence before further processes have been conducted. Our commitment is to provide a world standard quality service to our clients.

Clinical Facility
BEU is located in the Faculty of Medicine, Khon Kaen University. Our laboratory procedures and services are conducted in Srinagarind hospital buildings, with a Provincial Mental Hospital as another affiliated research unit. More than 200 healthy subjects, both males and females, have been registered in our Volunteer Bank. This provides both general and specific subjects for any requirement of the trial.
BEU clinical manipulating area is mainly set in Srinagarind hospital, Faculty of Medicine. Most parts are under air-conditioned system, cosy, and can be housed to 28 clinical trial subjects for an overnight stay. Settings of facility are especially suitable for the conduct in Pharmacokinetics, Pharmacogenetics and Bioequivalent studies.

The equipments in house include refrigerated centrifuge, -70oC freezers with Uninterrupted Power Supply etc. Essential equipments also consist of 2 set of HLPC systems.
All these facilities are operated in accordance to ICH GCP guidelines, with a group of qualified and experienced CPU nurses and technicians. Life supporting equipments are also essentially provided in each trial. All staff, such as GP Doctors, specialists (depend on studied drugs), pharmacists, nurses, technicians etc, have been trained according to ICH GCP guidelines.
