Sofosbuvir/velpatasvir, sold under the brand name Epclusa among others, is a fixed dose combination medication for the treatment of hepatitis C.[2] It combines sofosbuvir and velpatasvir.[2] It is more than 90% effective for hepatitis C genotypes one through six.[2] It also works for hepatitis C in those who also have cirrhosis or HIV/AIDS.[2] It is taken by mouth.[2]
The combination is generally well tolerated.[2] Common side effects include headaches, feeling tired, trouble sleeping, and nausea.[3] It has not been studied in pregnant women or during breastfeeding.[3] Greater care is required in those who are also infected with hepatitis B.[3] Sofosbuvir works by blocking the NS5B protein and velpatasvir works by blocking the NS5A protein.[3]
Sofosbuvir/velpatavir was approved for medical use in the United States in 2016.[3] It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system.[4] As of 2017, in the United States a course of treatment costs about 74,800 USD while in the developing world it costs about 900 USD.[2]
Medical uses
A single tablet regimen is used for adults with genotype 1–6 chronic hepatitis C virus (HCV) infection.[5]
Contraindications
Combining velpatasvir/sofosbuvir with strong inducers of the liver enzymes CYP2B6, CYP2C8 or CYP3A4, or with P-glycoprotein, is contraindicated because such substances may reduce the effectiveness of the hepatitis C drug.[6]
Side effects
Common side effects (in more than 10% of people) are headache, fatigue and nausea. In studies, severe side effects were experienced in 3% of patients, and 0.2% terminated the therapy because of adverse events. These effects occurred with similar frequencies in people treated with placebo.[6]
