Buprenorphine and cannabidiol co-administration reduces survival in a mouse model of orthopedic trauma.

ABSTRACT:

Introduction

Analgesic selection following orthopedic trauma presents unique challenges due to potential drug interactions and physiological stress. The impact of different analgesic regimens - buprenorphine, cannabidiol (CBD), their combination, or vehicle - on survival was investigated in a murine model of tibial fracture.

Methods

Eighty male C57BL/6 mice were randomly assigned to one of four group: (1) Buprenorphine (0.1 mg/kg, administered subcutaneously every 12 h for 3 days) plus cannabidiol (CBD, 100 mg/kg, administered intraperitoneally once daily for 7 days); (2) CBD only; (3) Buprenorphine + vehicle; or (4) Vehicle only. All animals also received carprofen (20 mg/kg, subcutaneously, once daily for 3 days). Survival was monitored over 7 days post-injury, and necrops
