Keeping this in consideration, is gabapentin a mast cell stabilizer?

Gabapentin inhibits bowel inflammation by regulating mast cell signaling. Furthermore, it activates the PPAR-gamma receptor, which in turn inhibits the activation of NFκB, and consequently results in reduced activation of inflammatory genes involved in inflammatory bowel diseases. Does Zyrtec help MCAS? Note: The H1 and H2 antihistamines are necessary to stabilize receptors on the mast cell. Medications to Treat Mast Cell Diseases.

H1-antihistamines are a standard treatment for mast cell-mediated allergic diseases. There is increasing evidence that histamine binding to H4 receptors exacerbates allergy and inflammation. Indeed, mast cells themselves have H4 receptors which when stimulated increased degranulation and cytokine production.
