What is Sofosbuvir 400 mg?
Sofosbuvir 400 mg is a prescription antiviral medication specifically formulated to treat chronic hepatitis C virus (HCV) infection. Developed by Natco Pharma Ltd., this medication is widely recognized for its ability to inhibit the replication of the hepatitis C virus within the body. It belongs to the class of drugs called nucleotide analog polymerase inhibitors and is considered a pivotal option in modern hepatitis C treatment protocols.
Chronic hepatitis C is a serious liver disease caused by the HCV, which can lead to severe liver damage, cirrhosis, or even liver cancer if left unmanaged. Sofosbuvir 400 mg works by targeting and blocking an essential enzyme that the virus requires to multiply, thereby helping to reduce viral load and manage the infection effectively.
Manufactured under strict quality controls by Natco Pharma Ltd., Sofosbuvir 400 mg offers an effective, safe, and well-tolerated treatment choice for patients diagnosed with chronic HCV infection. Its efficacy and safety profile have made it a preferred medication in Malaysia and many other countries worldwide.
This product is intended for use under medical supervision and forms part of combination therapy regimens, enhancing its effectiveness in achieving sustained virologic response.
Uses of Sofosbuvir 400 mg
- Treatment of chronic hepatitis C virus (HCV) infection
- Used in combination with other antiviral medications to increase treatment effectiveness
- Helps in reducing viral load to prevent liver damage
- Effective against multiple genotypes of hepatitis C virus
How Sofosbuvir 400 mg Works
Sofosbuvir 400 mg acts as a nucleotide analog inhibitor of the hepatitis C virus NS5B RNA-dependent RNA polymerase. This enzyme is crucial for viral replication. By inhibiting this polymerase, Sofosbuvir prevents the virus from replicating its RNA, effectively halting the multiplication process within infected liver cells.
The interruption of viral replication leads to a reduction in the amount of virus present in the bloodstream, which in turn supports the immune system in clearing the infection. This mechanism underpins the drug’s effectiveness in achieving sustained virologic response, a clinical marker indicating the successful elimination of the virus.

Sofosbuvir 400 mg tablets are typically taken orally once daily, with or without food, as directed by your healthcare provider. It is important to follow the prescribed regimen strictly to maximize the treatment’s effectiveness.
