“…The use of a combination of analgesics (NSAIDs, glucocorticoids, and opioids) could have many advantages, such as the induction of analgesia by different mechanisms of action, improved rapid recovery after surgery, less general toxicity, and adverse effects because the combination of drugs allows reducing the doses, particularly how much synergistic analgesic effects can be obtained using a combination of two or more drugs [ 24 , 25 , 26 , 27 , 28 , 29 , 30 ]. It is important to mention that evidence can also be found in clinical trials on the use of other opioid analgesics alone, or in combination with other types of drugs, to treat postoperative pain after a bunionectomy, such as tramadol [ 31 , 32 ], oxycodone [ 7 , 33 , 34 , 35 ], and morphine [ 33 , 36 , 37 ].…”
