Pharmacotherapy of Cystic Fibrosis

Pharmacotherapy relates to the use of chemical drugs to regulate and improve the function of defective CFTR channels.

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, G418

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.
