Description of Tenvir-EM

Tenvir EM is a combination tablet, which contains two anti-retroviral medications like Emtricitabine and Tenofovir disoproxil fumarate. Tenvir EM is established as combination dose for the treatment of HIV infection over the age of 18 years. Human immunodeficiency virus (HIV) weakens the immune system, by invading the precise immune cells called CD4 + cells, this cells plays important role in fencing against infection. Furthermore, CD4+ cells are destroyed which leads to life threatening condition like AIDS. This tablet anticipate the ability of HIV to multiply and spread, which reduce the counting of virus and leads to increase the CD4+ cell numbers. As a result of this, immune system can regain its capability, by decreasing the risk of disease evolution. Pre-exposure prophylaxis (PrEP): Tenvir EM is used in pre exposure prophylaxis treatment. It is a new obstruction method, in which the people not affected by HIV infection, but they might have chance to get infection. In this condition, Tenvir EM is taken to eradicate the suspected infection. Person who is undergoing PrEP treatment should contact with medical practitioner for every 3 months to investigate and testing the level of infection.

Pharmacology of Tenvir-EM

Pharmacodynamic: Emtricitabine: ↓ It is synthetic nucleoside counterpart of cytidine ↓phosphorylated by cellular enzymes Converted to Emtricitabine 5’-triphosphate ↓ Inhibits the activity of HIV-1 reverse transcriptase ↓ Encounters with deoxycytidine 5 triphosphate ↓ Integrated into viral DNA ↓ Chain termination Tenofovir disoproxil fumarate: Tenvir EM is an acyclic nucleoside phosphonate diester analog of adenosine monophosphate. Tenofovir disoproxil fumarate ¬diester hydrolysis→ tenofovir Tenofovir →phosphorylation by cellular enzymes tenofovir diphosphate Tenofovir diphosphate prohibits the activity of HIV 1 RT by competing with natural substrate (deoxyadenosine 5’-triphosphate), fusing into DNA, by DNA chain termination. Both tenofovir and Emtricitabine are weak inhibitor of mammalian DNA polymerase α, β, epsilon and mitochondrial DNA polymerase gamma. Pharmacokinetic: Absorption: Tenvir EM is rapidly absorbed with peak plasma concentration occurring within 1-2 hours. Distribution: Tenvir EM is highly bound to the human plasma protein over the range of 0.02-200 μg/mL (Emtricitabine) and 0.01–25 μg/mL (tenofovir). Metabolism: Tenvir EM is metabolized and its metabolites are released through urine. Excretion: Excretion of tablet Tenvir EM occurs through urine. The mean plasma termination half life period of tablet Tenvir EM is Emtricitabine 10 hours; tenofovir 17 hours.
