Tenvir 300mg Tablet

1. Product Introduction:

Tenvir 300mg Tablet is an antiviral medication containing the active ingredient Tenofovir Disoproxil Fumarate (TDF), which belongs to a class of drugs known as nucleotide reverse transcriptase inhibitors (NRTIs). It is primarily used in the treatment and management of HIV-1 infection and chronic hepatitis B virus (HBV) infection.

Manufactured by Cipla Ltd, Tenvir is a widely prescribed antiretroviral drug that works by inhibiting the replication of viruses in the body, helping to control the progression of infection. Though not a cure for HIV or hepatitis B, it is highly effective in reducing the viral load in the body and improving immune function when used regularly and as prescribed.

2. Uses of This Medicine:

Tenvir 300mg Tablet is used for the following purposes:

• Treatment of HIV-1 Infection:
  It is part of combination antiretroviral therapy (ART) to manage human immunodeficiency virus (HIV-1) infection in adults and adolescents.

• Chronic Hepatitis B (HBV) Treatment:
  Tenvir helps in suppressing hepatitis B virus replication and preventing liver damage, cirrhosis, and liver cancer in patients with chronic HBV.

• Post-Exposure Prophylaxis (PEP):
  In some cases, Tenvir is used along with other antiretrovirals as PEP after potential exposure to HIV, such as needle stick injury or unprotected sex.

• Pre-Exposure Prophylaxis (PrEP) (Off-label):
  Though not officially marketed for PrEP in all regions, Tenofovir is part of combinations used to reduce the risk of acquiring HIV in high-risk individuals.

3. Benefits of This Medicine:

• Reduces HIV Viral Load:
  Tenvir effectively lowers the amount of HIV in the blood, helping to keep the infection under control and reduce transmission risk.

• Improves Immune Function:
  Regular use helps increase CD4+ T-cell count, which are key immune cells damaged by HIV, improving overall immunity.

• Delays Disease Progression:
  By maintaining viral suppression, Tenvir reduces the risk of developing AIDS and related opportunistic infections.

• Protects Liver Function in HBV:
  In chronic hepatitis B patients, Tenvir prevents further liver damage, reduces inflammation, and lowers the risk of developing liver cirrhosis or cancer.

• Once-Daily Dosage:
  The convenient once-daily oral dose improves patient compliance and long-term adherence to therapy.

• Used in Combination Therapy:
  Tenvir is a core component in many first-line antiretroviral combinations recommended by WHO and national treatment guidelines.
