What condition does Letermovir treat?

Letermovir is used to prevent disease caused by a virus called cytomegalovirus (CMV). CMV usually occurs in people who have received a bone marrow transplant. It is a type of disease that leads to serious infections in the body which includes infection in the eye called CMV retinitis that may cause blindness.

This prescription is an anti-viral medicine that helps prevent or stop the growth of the virus that is present in your body. This medication is an inhibitor of the CMV DNA terminase complex. The Food and Drug Administration (FDA) has approved this medication that is available as a tablet for oral use.

How does Letermovir work?

Letermovir stops the activity of this complex to prevent the creation of mature viral genomes and the production of viable viral particles. This also stops the CMV DNA terminase complex which is needed for cleavage and wrapping of viral progeny DNA. Letermovir affects the development of suitable unit-length genomes and interferes with virion maturation. Genotypic categorization of virus resistant to this medicine confirmed that this targets the terminase complex.
