About

Cystic fibrosis is a genetic disorder that causes thick mucus to build up in the lungs and other organs, leading to frequent infections, breathing difficulties, and long-term organ damage. Alyftrek and Trikafta are combination drugs that work to improve the function of the defective protein underlying the disease. By helping this protein work better, these treatments may reduce mucus buildup and the resulting complications for a broad range of patients.
