Tenofovir disoproxil Zentiva 245 mg film-coated tablets

HIV-1 infection Tenofovir disoproxil Zentiva is indicated in combination with other antiretroviral medicinal products for the treatment of HIV-1 infected adults. In adults, the demonstration of the benefit of tenofovir disoproxil in HIV-1 infection is based on results of one study in treatment-naïve patients, including patients with a high viral load (> 100,000 copies/ml) and studies in which tenofovir disoproxil was added to stable background therapy (mainly tritherapy) in antiretroviral pre-treated patients experiencing early virological failure (< 10,000 copies/ml, with the majority of patients having < 5,000 copies/ml). Tenofovir disoproxil Zentiva is also indicated for the treatment of HIV-1 infected adolescents, with NRTI resistance or toxicities precluding the use of first line agents, aged 12 to < 18 years. The choice of Tenofovir disoproxil Zentiva to treat antiretroviral-experienced patients with HIV-1 infection should be based on individual viral resistance testing and/or treatment history of patients. Hepatitis B infection Tenofovir disoproxil Zentiva is indicated for the treatment of chronic hepatitis B in adults with: - compensated liver disease, with evidence of active viral replication, persistently elevated serum alanine aminotransferase (ALT) levels and histological evidence of active inflammation and/or fibrosis (see section 5.1). - evidence of lamivudine-resistant hepatitis B virus (see sections 4.8 and 5.1). - decompensated liver disease (see sections 4.4, 4.8 and 5.1). Tenofovir disoproxil Zentiva is indicated for the treatment of chronic hepatitis B in adolescents 12 to < 18 years of age with: - compensated liver disease and evidence of immune active disease, i.e. active viral replication and persistently elevated serum ALT levels, or histological evidence of moderate to severe inflammation and/or fibrosis-. With respect to the decision to initiate treatment in paediatric patients, see sections 4.2, 4.4, 4.8 and 5.1.

Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva 600 mg/200 mg/245 mg film-coated tablets

Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva is a fixed-dose combination of efavirenz, emtricitabine and tenofovir disoproxil. It is indicated for the treatment of human immunodeficiency virus-1 (HIV-1) infection in adults aged 18 years and over with virologic suppression to HIV-1 RNA levels of < 50 copies/ml on their current combination antiretroviral therapy for more than three months. Patients must not have experienced virological failure on any prior antiretroviral therapy and must be known not to have harboured virus strains with mutations conferring significant resistance to any of the three components contained in Efavirenz/Emtricitabine/Tenofovir disoproxil Zentiva prior to initiation of their first antiretroviral treatment regimen (see sections 4.4 and 5.1). The demonstration of the benefit of the combination efavirenz/emtricitabine/tenofovir disoproxil is primarily based on 48-week data from a clinical study in which patients with stable virologic suppression on a combination antiretroviral therapy changed to efavirenz/emtricitabine/tenofovir disoproxil (see section 5.1). No data are currently available from clinical studies with combination efavirenz/emtricitabine/tenofovir disoproxil in treatment-naïve or in heavily pretreated patients. No data are available to support the combination of efavirenz/emtricitabine/tenofovir disoproxil and other antiretroviral agents.
