The voltage-gated sodium channel subtype Nav1.7 is highly expressed in nociceptive sensory neurons and is a key pathogenic target in several human hereditary pain syndromes. In recent years, a large number of studies have shown that Nav1.7 plays an important role in inflammatory, neuropathic, and nociceptive pain. Therefore, targeting Nav1.7 is a new strategy and hotspot for the development of novel analgesics. This review introduces the structure and function of Nav1.7, its regulatory role in pain, highlights the development progress of small-molecule Nav1.7 inhibitors in clinical trials, and analyzes the preclinical development of highly specific Nav1.7 inhibitors, with a view to providing reference for the development of Nav1.7 analgesic drugs.
