What is Lonafarnib and explain in detail?
Lonafarnib, sold under the brand name Zokinvy, is a medication used to reduce the risk of death due to Hutchinson-Gilford progeria syndrome and for the treatment of certain processing-deficient progeroid laminopathies in people one year of age and older.The most common side effects included nausea vomiting, headache, diarrhea, infection, decreased appetite and fatigue.Lonafarnib was approved for medical use in the United States in November 2020, and in the European Union in July 2022. The U.S. Food and Drug Administration (FDA) considers it to be a first-in-class medication.

Medical uses
Lonafarnib is indicated to be used to reduce the risk of death due to Hutchinson-Gilford progeria syndrome and for the treatment of certain other processing-deficient progeroid laminopathies in people one year of age and older.

Contraindications
Lonafarnib is contraindicated for co-administration with strong or moderate CYP3A inhibitors and inducers, as well as midazolam and certain cholesterol-lowering medications.

History
Lonafarnib, a farnesyltransferase inhibitor, is an oral medication that helps prevent the buildup of defective progerin or progerin-like protein. The effectiveness of lonafarnib for the treatment of Hutchinson-Gilford progeria syndrome was demonstrated in 62 patients from two single-arm trials (Trial 1/NCT00425607 and Trial 2/NCT00916747) that were compared to matched, untreated patients from a separate natural history study. Compared to untreated patients, the lifespan of Hutchinson-Gilford progeria syndrome patients treated with lonafarnib increased by an average of three months through the first three years of treatment and by an average of 2.5 years through the maximum follow-up time of 11 years. Lonafarnibs approval for the treatment of certain processing-deficient progeroid laminopathies that are very rare took into account similarities in the underlying genetic mechanism of disease and other available data. The participants were from 34 countries around the world, including the United States.The U.S. Food and Drug Administration (FDA) granted the application for lonafarnib priority review, orphan drug, and breakthrough therapy designations
