Tenvir

Tenvir-EM (Tenofovir Disoproxil Fumarate/Emtricitabine) is indicated in combination with other antiretroviral agents for the treatment of HIV-1 infection in adults. Each film coated tablet contains 300mg of Tenofovir Disoproxil Fumarate and 200mg of Emtricitabine.

Tenofovir Disoproxil Fumarate is an acyclic nucleoside phosphonate diester analog of adenosine monophosphate. It requires initial diester hydrolysis for conversion to tenofovir and subsequent phosphorylations by cellular enzymes to form tenofovir diphosphate. It inhibits the activity of HIV-1 reverse transcriptase by competing with the natural substrate deoxyadenosine 5`-triphosphate and, after incorporation into DNA, by DNA chain termination. It is a weak inhibitor of mammalian DNA polymerases alpha and beta, and mitochondrial DNA polymerase gamma.

The dose is one tablet taken once daily taken orally with or without food. Strictly follow all instructions provided to you by your physician or pharmacist while using Tenvir (Tenofovir Disoproxil Fumarate). Optimum and safe dosage can differ based on the patient and the condition being treated.
