Overview  

Tenofovir disoproxil fumarate, Emtricitabine, and Efavirenz are active ingredients that are to prevent the multiplication of HIV (human immunodeficiency virus), and together they form a tablet known as Teefavir and these ingredients work in a combination to decrease the amount of HIV infection. This medication boosts your immune system to fight against HIV and manage AIDS (Acquired immunodeficiency syndrome). Do not stop the dosage of Teefavir tablets without taking permission from your physician.  

Pharmacodynamics  

Tenofovir Disoproxil Fumarate (Teefavir):- This is particularly a nucleoside (acyclic) phosphonate diester analog of adenosine monophosphate. It usually requires initial diester hydrolysis in order to convert it to tenofovir and subsequent phosphorylations through cellular enzymes and form tenofovir diphosphate. It works to inhibit the activity of HIV-1 RT by competing with the natural substrate deoxyadenosine 5′-triphosphate and, after incorporation into DNA, by DNA chain termination.   

Emtricitabine (Teefavir):- It is a synthetic nucleoside analog of cytidine. This compound is phosphorylated by cellular enzymes for the formation of emtricitabine 5'-triphosphate. Emtricitabine works to inhibit the activity of the HIV-1 reverse transcriptase (RT) through competing with the natural substrate deoxycytidine 5'-triphosphate and by incorporating it into nascent viral DNA resulting in chain termination. The compound is a weak inhibitor of mammalian DNA polymerase alpha, beta, epsilon, and mitochondrial DNA polymerase gamma.  

Efavirenz (Teefavir):- It is an oral non-nucleoside reverse transcriptase inhibitor. This compound is a synthetic purine derivative. It is similar to zidovudine stavudine. It was originally approved to treat HIV infections and AIDS in patients who failed therapy with zidovudine.
