“…15 Accordingly, the efficacy of several drugs as adjuvants has been studied, including NSAIDs, ketamine, local anesthetics, and opioids. [16][17][18][19] Recently, gabapentinoids have attracted attention in the surgical setting as an adjuvant to a multimodal postoperative pain management strategy. Gabapentinoids bind at the a2-d subunit of presynaptic voltage-gated calcium channels and exert analgesic effects by reducing the release of several excitatory neurotransmitters such as calcitonin gene-related peptide, glutamate, noradrenaline, and substance P. 20 Also, gabapentinoids administered before surgical trauma have been shown to interact with other analgesics additively or synergistically to decrease inflammatory hyperalgesia.…”
