Procedure

The NMP and a portion of the polyethylene glycol 200 are charged to the compounding vessel. Florfenicol, methyl p-hydroxybenzoate and propyl p-hydroxybenzoate are added to the vessel and mixed until dissolved. Water is added, followed by the flunixin meglumine, and mixed until solids are dissolved. Q.S. to final volume with polyethylene glycol 200 if needed.
