Trikafta
Generic name: Elexacaftor, Ivacaftor, And Tezacaftor
Dosage form: oral tablets, oral granules
Drug class:
CFTR combinations
Usage of Trikafta
Trikafta is an oral combination medication that contains elexacaftor, ivacaftor, and tezacaftor, which may be used to treat adults and children aged 2 years and older with cystic fibrosis who have at least one copy of the F508del mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene or another mutation that is responsive to treatment with Trikafta.
Cystic fibrosis (CF) is caused by mutations in the CF gene, which causes a specific protein, called the cystic fibrosis transmembrane conductance regulator (CFTR) protein to not work the way it should. Fewer CFTR proteins get to the cell surface and, if they do reach the cell surface, do not open the way they should, which prevents the proper movements of chloride ions in and out of the cell. As a result, thick sticky mucus builds up in the organs, including the lungs.
The three ingredients in Trikafta work together to improve the functioning of the CFTR protein:
Before you take this medicine, you may need an FDA-approved CF mutation test to make sure you have either the F508del mutation or at least one other eligible mutation.
Trikafta was first FDA-approved on October 21, 2019.
