(ELBASVIR AND GRAZOPREVIR)
DONE BY : HUSSIEN SALAM

2. HEPATITIS
• Hepatitis refers to an inflammatory condition of the liver. It’s
commonly caused by a viral infection.
• Viral infections of the liver that are classified as hepatitis include
hepatitis A, B, C, D, and E.
• Hepatitis A is a milder version of the disease, and hepatitis C and
D are more severe.

3. HEPATITIS C
• Hepatitis C is a viral disease that causes inflammation of the liver
that can lead to diminished liver function or liver failure. Most
people infected with HCV have no symptoms of the disease until
liver damage becomes apparent, which may take several years.

4. HEPATITIS C
• Some people with chronic HCV infection develop cirrhosis over
many years, which can lead to complications such as bleeding,
jaundice (yellowish eyes or skin), fluid accumulation in the
abdomen, infections or liver cancer.

hours (range of 3 to 6 hours); grazoprevir peak concentrations
occur at a median Tmax of 2 hours (range of 30 minutes to 3 hours).
• Distribution: Elbasvir and grazoprevir are extensively bound
