Ganciclovir – Antiviral for Cytomegalovirus (CMV) Infections (Rx)

Ganciclovir is a broad-spectrum antiviral medication primarily used for the treatment and prevention of cytomegalovirus (CMV) infections, especially in immunocompromised patients such as transplant recipients or individuals with advanced HIV infection.

It is a nucleoside analogue antiviral that works by inhibiting viral DNA polymerase, thereby blocking viral replication and limiting the spread of infection within the body.

Ganciclovir is commonly used for CMV retinitis, CMV pneumonia, and systemic CMV infections, and may also be used prophylactically in high-risk patients.
