The concurrent use of 2.5% polyacrylamide hydrogel and betamethasone esters for intra-articular injection is well tolerated in 10 healthy horses.

Objective: This study assessed the safety and tolerability of concurrent intra-articular (IA) injection of 2.5% polyacrylamide hydrogel (2.5% iPAAG) and betamethasone sodium phosphate and betamethasone acetate esters (BME) in the metacarpophalangeal joints (MCPJs) of healthy horses.
