Introduction to Harvoni (Ledipasvir & Sofosbuvir) 90mg
Harvoni (Ledipasvir & Sofosbuvir) 90mg is a prescription antiviral medicine used in the treatment of chronic hepatitis C virus (HCV) infection. This medicine combines two direct-acting antiviral agents that work together to block the virus from multiplying and help clear the infection from the body.
Harvoni (Ledipasvir & Sofosbuvir) 90mg is classified under Prescription Medicines, Antiviral Medicines, Hepatitis C Treatments, and Oral Antiviral Therapies. It contains Ledipasvir and Sofosbuvir, which help prevent the hepatitis C virus from reproducing and support long-term viral suppression.
In some markets, Twinvir 90mg is available as a generic brand containing the same active ingredients Ledipasvir and Sofosbuvir, offering a similar therapeutic effect when prescribed by a qualified healthcare professional.
What Is Harvoni (Ledipasvir & Sofosbuvir)?
Harvoni is the brand name for the combination of Ledipasvir and Sofosbuvir, an oral medication widely used for the treatment of chronic hepatitis C infection.
Ledipasvir & Sofosbuvir belong to a class of medicines known as Direct-Acting Antivirals (DAAs). These medicines directly target specific steps in the hepatitis C virus life cycle, helping reduce viral load and achieve sustained virologic response.
Generic versions such as Twinvir 90mg contain the same active compounds and may be used depending on physician recommendation and regional availability.
Drug Class and Mechanism of Action
Ledipasvir & Sofosbuvir are classified as direct-acting antiviral agents with potent anti-HCV activity.
How Ledipasvir & Sofosbuvir Work
It works in several ways:
- Ledipasvir inhibits the HCV NS5A protein, which is needed for viral replication
- Sofosbuvir inhibits the HCV NS5B RNA polymerase, blocking viral RNA synthesis
- Together they reduce the ability of the virus to survive and multiply
Through these mechanisms, Ledipasvir & Sofosbuvir help eliminate hepatitis C infection in many patients.
How Harvoni Works in the Body
The hepatitis C virus depends on specific proteins and enzymes to replicate inside the liver. Harvoni interferes with these viral processes and helps stop the infection cycle.
Key Actions of Ledipasvir & Sofosbuvir
- Blocking NS5A protein activity required for viral assembly and replication
- Inhibiting NS5B polymerase needed for viral RNA production
- Reducing viral load and improving the chance of long-term cure
Some generic versions such as Twinvir deliver the same active compounds, allowing similar hepatitis C treatment when prescribed appropriately.
