Role of antiviral medicines in the treatment of chronic hepatitis
Antiviral medicines play a crucial role in the treatment of chronic hepatitis, particularly in cases caused by hepatitis B virus (HBV) and hepatitis C virus (HCV). These medications are specifically designed to target and inhibit the replication of these viruses, thereby reducing viral load and preventing liver damage. Unlike antibiotics, which are effective against bacteria, antivirals specifically target viruses and inhibit their ability to replicate and spread within the body.
Antiviral medicines can be used to treat a variety of viral infections, including influenza (flu), herpes viruses (such as herpes simplex and herpes zoster), human immunodeficiency virus (HIV), hepatitis B and C viruses, and respiratory syncytial virus (RSV), among others.
Chronic hepatitis
Chronic hepatitis refers to long-term inflammation of the liver that lasts for at least six months. It is usually caused by viral infections, most commonly hepatitis B virus (HBV) or hepatitis C virus (HCV).
Chronic hepatitis B and C are significant public health concerns worldwide. They can lead to severe liver damage, cirrhosis (scarring of the liver), liver failure, and an increased risk of liver cancer. It is important to diagnose and manage chronic hepatitis to prevent these complications.
Chronic hepatitis treatment
The treatment of chronic hepatitis depends on the underlying cause. For chronic hepatitis B, antiviral medications such as tenofovir or entecavir are commonly used to suppress viral replication and reduce liver inflammation. These medications help slow down disease progression and decrease the risk of complications.
Chronic Hepatitis B:
Antiviral Medications: Antiviral drugs such as tenofovir disoproxil fumarate (TDF), tenofovir alafenamide (TAF), entecavir, and pegylated interferon-alpha are commonly used to suppress viral replication and reduce liver inflammation. These medications can help slow down the progression of the disease, prevent liver damage, and reduce the risk of complications.
Chronic Hepatitis C:
Direct-Acting Antiviral (DAA) Therapy: Chronic hepatitis C can often be cured with oral antiviral medications known as directacting antivirals. These medications specifically target the hepatitis C virus, inhibiting its replication and leading to sustained virologic response (SVR), which is considered a cure. They are typically used in combination regimens for a specific duration, depending on the genotype of the HCV infection. Some examples include sofosbuvir, ledipasvir, velpatasvir, glecaprevir, and pibrentasvir.
Daclatasvir works by targeting and inhibiting the HCV nonstructural protein NS5A. This protein plays a vital role in viral replication and assembly. By blocking NS5A, daclatasvir prevents the virus from multiplying and spreading within the liver. Hepcdac 60mg Tablet is an antiviral medicine containing the active constituent daclatasvir. It is used to treat chronic hepatitis C infection in adults. It is usually prescribed as part of combination therapy with other DAAs.
It’s important to note that the choice of antiviral medication and the duration of treatment will depend on the specific hepatitis virus (HBV or HCV), individual patient factors, and the stage of liver disease.
