Why is this medication prescribed?

Zokinvy (lonafarnib) is prescribed for the treatment of Hutchinson-Gilford progeria syndrome (HGPS) or progeria. Progeria is an extremely rare genetic disorder characterized by accelerated aging in children. It leads to various physical and medical complications, including cardiovascular issues, skeletal abnormalities, and a shortened lifespan.

Zokinvy is a farnesyltransferase inhibitor, and it works by blocking an enzyme called farnesyltransferase. This enzyme is involved in the processing of a protein called progerin, which is responsible for the symptoms of progeria. By inhibiting farnesyltransferase, Zokinvy helps reduce the production of progerin, thereby slowing down the progression of the disease and alleviating some of its symptoms.

How should this medicine be used?

Zokinvy (lonafarnib) is an oral medication used for the treatment of Hutchinson-Gilford progeria syndrome (HGPS). The dosage and administration instructions for Zokinvy are typically tailored to the individual patient by a healthcare provider. Patients are advised to follow their healthcare provider’s recommendations regarding how to take Zokinvy.

In general, oral medications are often taken with water and may be prescribed to be taken with or without food, depending on the specific medication. It is crucial for individuals prescribed Zokinvy to:
