A multimodal anti-emetic anesthetic/analgesic formulation for pain control not limited to postoperative pain control is described herein. The opioid-free/sparing anesthetic/analgesic formulation comprises a local anesthetic, an N-methyl-D-aspartate (NMDA) receptor antagonist, and a cyclooxygenase (COX) inhibitor such as Bupivacaine Hydrochloride, Ketamine Hydrochloride, and Ketorolac Tromethamine, which is effective to significantly reduce postoperative nausea and vomiting and enhance postoperative pain relief as compared to existing prior art anesthetics/analgesics. The formulation is administered to a mammal in need of anesthesia/analgesia and can be used as a preemptive and preventative multimodal analgesic. The formulation may have a buffer to enhance its shelf life and improve pharmacokinetics. The formulation may further comprise an alpha agonist, a steroid, a Transient Receptor Potential Channel agonist or antagonist, a beta-lactam antibiotic, a protein kinase inhibitor, a competitive or non-competitive glycine or glutamate antagonist, a glutamate or glycine inhibitor, a cyclooxygenase 3 inhibitor, or combinations thereof.
