Pharmacotherapy of Cystic Fibrosis
Pharmacotherapy relates to the use of chemical drugs to regulate and improve the function of defective CFTR channels.[1]
Potentiators
Example: VX-770
Attempt to correct Class III and Class IV CFTR mutations by increasing the conductance of the CFTR channel.
Correctors
Example: Trimethyl-oxide
Attempt to correct Class II CFTR mutations by improving the trafficking of CFTR channels to the Cell Membrane.
Termination Suppressors
Example: Gentamicin, G41, PTC124 (Ataluren[2])
Suppress termination mutations which would normal result in premature termination and truncation of the protein. These drugs are designed to restore 'read-through' and enable the production of normal CFTR.
