HepBest is an oral antiviral medication that contains tenofovir alafenamide as its active ingredient. It is primarily used in the treatment of chronic hepatitis B virus (HBV) infection. Tenofovir alafenamide is a newer and improved version of tenofovir, designed to deliver the drug more efficiently to the liver, where it is needed most, while reducing its impact on the kidneys and bones. HepBest offers a once-daily treatment option that is both effective and better tolerated for long-term use.

Mechanism of Action:
HepBest works by targeting the replication process of the hepatitis B virus:

• Tenofovir alafenamide is a prodrug, meaning it becomes active only after it enters the body. It is taken up by liver cells, where it is converted into the active form called tenofovir diphosphate.

• This active substance blocks the reverse transcriptase enzyme that HBV uses to replicate its genetic material.

• By interfering with this enzyme, HepBest stops the virus from multiplying and helps reduce the viral load in the blood.

  Uses:
  HepBest is used for:

  • The treatment of chronic hepatitis B infection in adults and adolescents aged twelve years and older, especially those with evidence of active viral replication and liver damage.

  • It helps to lower the amount of virus in the body, improve liver function, and prevent further liver damage.

    Adverse Effects:
    HepBest is generally well-tolerated, especially compared to older forms of tenofovir. However, like all medications, it can cause side effects. The most commonly reported ones include:

    • Headache

    • Fatigue

    • Nausea

    • Stomach discomfort
