Tenofovir Alafenamide Fumarate & Emtricitabine

TAF and Emtricitabine are nucleotide reverse transcriptase inhibitor that involved in suppression of growth of HIV virus associated with AIDS

Tafero EM Indication

Tafero EM , a combination tablet contains tenofovir Alafenamide fumarate and Emtricitabine is mainly indicated for the treatment of HIV-1 infection in adult’s patients.



Tafero EM Pharmacology



TAF (Tenofovir Alafenamide Fumarate)

TAF is a novel ester prodrug of anti-retroviral tenofovir, and it is a nucleotide reverse transcriptase inhibitor After an oral administration, TAF is transformed into tenofovir Tenofovir (acyclic nucleoside phosphonate analog of adenosine 5 monophosphate)

Tenofovir depletes DNA binding, there is a lack of 3 OH molecules (water molecules are responsible for phosphodiester bond linkage) By opposing the regular nucleotide for insertion into proviral DNA and blockade of formation of 5 to 3 phosphodiester linkage which is needed for DNA elongation Tenofovir leads to chain termination and block proviral DNA transcription

Emtricitabine

Emtricitabine is one of the components of Tafero EM it exhibits its anti-retroviral activity by inhibiting reverse transcriptase, the enzyme which is responsible for transcript HIV RNA into new viral DNA. Emtricitabine is phosphorylated to Emtricitabine 5 phosphate with the help of cellular enzymes

Emtricitabine 5 phosphates is HIV-1 reverse transcriptase inhibitor Emtricitabine 5 phosphates fight with deoxycytidine 5 triphosphate (natural substrate) and inserted into viral DNA causes chain termination




PHARMACOKINETIC

Tafero EM the absorption of tenofovir is occur fastly and its Tmax is observed at 1 hour after administration; whereas Emtricitabine is absorbed rapidly and its mean bioavailability is 93%

The human plasma protein bound of Emtricitabine is very low less than 4% Tenofovir is highly bound to human plasma protein with the range of 80%

TAF, is hydrolyzed into tenofovir within the cells, it is the major metabolite again phosphorylated into tenofovir diphosphate active metabolite Emtricitabine is metabolized minimally and it is found in urine as unchanged form

The route of elimination mostly through urine The terminal half life of Emtricitabine is 10 hours The terminal half life period of tenofovir is 0.51 hour

Tafero EM Drug interaction




  • Acyclovir-valaciclovir: increase the serum concentration of tenofovir
  • Adefovir: decrease the therapeutic effect of tenofovir
  • Amino glycosides: increase the serum concentration of tenofovir
  • Carbamazepine: decrease the serum concentration of tenofovir
  • Cidofovir: increase the serum concentration of tenofovir
  • Cobicistat: may increase the toxic effects of tenofovir
  • Diclofenac: may enhance the nephrotoxicity effect of tenofovir
  • Fosphenytoin/phenytoin: decrease the serum concentration of tenofovir
  • Lamivudine: increase toxic effects of Emtricitabine
  • NSAIDS: increase the nephrotoxicity effect of tenofovir
  • Orlistat: decrease the serum concentration of anti-retroviral drugs Oxcarbazepine, Phenobarbital, primidone, rifabutin, rifampin, rifapentine, st.Johns wort, tipranavir these are the drugs which involved in depletion of serum concentration of tenofovir
