Tenofovir disoproxil phosphate

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 (nucleotide reverse transcriptase inhibitor) 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, persistently elevated serum ALT levels and histological evidence of active inflammation and/or fibrosis (see sections 4.4, 4.8 and 5.1).
