Scarnet Injection

Product Details

Scarnet Injection contains Foscarnet 24 mg, a generic for Foscavir Injection. It is an antiviral medication used primarily for the treatment of cytomegalovirus (CMV) infections in immunocompromised patients, such as those with HIV/AIDS or undergoing organ transplants. Scarnet is also effective against certain types of herpesvirus infections, especially those resistant to other antiviral drugs.

Uses

1. Cytomegalovirus (CMV) Infections: Treats CMV retinitis and other manifestations in immunocompromised patients.
2. Acyclovir-Resistant Herpes Simplex Virus (HSV) Infections: Used for herpesvirus infections that do not respond to standard therapies.

How Scarnet Injection Works

Foscarnet works by directly inhibiting viral DNA polymerase, an enzyme essential for viral replication. Unlike other antivirals, it does not require activation by viral enzymes, making it effective against drug-resistant strains of herpesviruses and CMV.
