Capsaicin is able to induce mast cell degranulation, an event probably related to the pathophysiology of a migraine attack. Objectives: The present review study aimed to address the mechanisms of action of capsaicin and other chemical inducers in mast cell degranulation and an interaction of nerves and events that happen in the dura mater with the activation of mast cells. Design: A survey was carried out in the literature, from 1980 to 2019, in different databases (SciELO, U.S. National Library of Medicine and the National Institutes Health (PubMed) and Web of Science) using the following terms: capsaicin, mast cell and dura mater. Methods: 36 articles were selected for this review. The inclusion criteria were experimental model studies in rats that described the mechanisms of action of chemical inducers, including capsaicin. Results: Studies indicate that the main mechanisms of action of capsaicin are chemical induction through the activation of TRPV1 channels, allowing calcium influx into neurons in the trigeminal ganglion of the dura mater, activating mast cell degranulation, releasing pro-inflammatory (e.g., histamine, oxide nitric) and vasoactive (e.g., CGRP and substance P) substances. Conclusion: Therefore, the use of capsaicin may be a tool to be used in na animal model to better understand the pathophysiology of migraine.
