Various mutations of the cystic fibrosis gene block the "gates" that allow the flow of salt across the cell membranes. This causes mucus to become thick and clog the lungs. Trikafta® helps "open the gates" more often allowing more salt to pass through. The thick mucus is reduced and cystic fibrosis symptoms lessen.
