Mechanism Of Action Crofelemer is an inhibitor of the cystic fibrosis transmembrane regulator chloride channel (CFTR) , as evidenced by its activity on cell cultures, single cell patch clamps, single CFTR channels, and elaboration of mouse intestinal fluid secretion. Crofelemer also inhibits calcium activated chloride channels (CaCC) , which in combination with CFTR, are expressed on the luminal side of intestinal cells. Crofelemer inhibition of both of these channels prevents water loss from diarrhea by inhibiting chloride secretion.
Description of the Drug: Crofelemer is an antidiarrheal agent used for the symptomatic relief of drug-induced non-infectious diarrhea in adult patients with HIV/AIDS receiving antiretroviral therapy.
