What is this medication?
Antiretroviral, Reverse Transcriptase Inhibitor
Efavirenz+Emtricitabine+Tenofovir, Atripla is indicated for treatment of HIV-1 Infection.
“Alert: Black Box Warning
Post-Treatment Acute Exacerbation of Hepatitis B
Severe, acute exacerbations of hepatitis B virus (HBV) have been reported in patients who are co-infected with HIV-1 and HBV and have discontinued products containing emtricitabine and/or tenofovir disoproxil fumarate. Closely monitor hepatic function with both clinical and laboratory follow-up for at least several months in patients who are coinfected with HIV-1 and HBV and discontinue efavirenz/emtricitabine/tenofovir disoproxil fumarate. If appropriate, initiation of anti-hepatitis B therapy may be warranted.”
How does this medication work?
Efavirenz is a non-nucleoside reverse transcriptase inhibitor of HIV-1. It consequently blocks the RNA-dependent and DNA-dependent DNA polymerase activities including HIV-1 replication. Emtricitabine is a nucleoside reverse transcriptase inhibitor; cytosine analogue that is phosphorylated intracellularly to emtricitabine 5′-triphosphate which interferes with HIV viral RNA dependent DNA polymerase resulting in inhibition of viral replication.
Tenofovir disoproxil fumarate is a nucleotide reverse transcriptase inhibitor; analog of adenosine 5′-monophosphate that interferes with the HIV viral RNA dependent DNA polymerase resulting in inhibition of viral replication. TDF is first converted intracellularly by hydrolysis to tenofovir and subsequently phosphorylated to the active tenofovir diphosphate. Tenofovir inhibits replication of HBV by inhibiting HBV polymerase.
How should I take this medication?
Oral: Take 1 tablets once daily.
How to Take:
