HepBest contains tenofovir alafenamide (TAF), an antiviral medicine. It belongs to the class of nucleotide reverse transcriptase inhibitors (NRTIs) and is mainly used for chronic hepatitis B virus (HBV) infection. Compared to the older form (tenofovir disoproxil fumarate – TDF), TAF works at lower doses and is safer for kidneys and bones.

Mechanism of Action

• Inside the body, TAF is converted into tenofovir diphosphate.

• This active form blocks the reverse transcriptase enzyme of HBV.

• By doing this, it prevents the virus from multiplying and reduces viral load in the liver.

• It helps slow liver damage and lowers the risk of complications.

  Uses 

  • Chronic hepatitis B infection in adults and adolescents

  • Helps in reducing liver damage, cirrhosis, and liver cancer risk associated with long-term HBV infection

    Adverse Effects
