FDA approves Pifeltro ( doravirine )

Doravirine has been used in trials studying the treatment of HIV-1, HIV-1 Infection, Renal Impairment, and Human Immunodeficiency Virus (HIV) Infection. In particular, doravirine is an HIV-1 non-nucleoside reverse transcriptase inhibitor (NNRTI) intended to be administered in combination with other antiretroviral medicines [FDA Label, L4562]. Doravirine is subsequently available by itself or as a combination product of doravirine (100 mg), lamivudine (300 mg), and tenofovir disoproxil fumarate (300 mg) [L4562]. Doravirine is formally indicated for the treatment of HIV-1 infection in adult patients with no prior antiretroviral treatment experience, further expanding the possibility and choice of therapeutic treatments available for managing HIV-1 infection or AIDS [L4562].
