Etravirine

Etravirine is a non-nucleoside reverse transcriptase inhibitor (NNRTI) used for the treatment of HIV.
Etravirine is an aminopyrimidine that consists of 2,6-diaminopyrimidine bearing a bromo substituent at position 5, a 4-cyano-2,6-dimethylphenoxy substituent at position 4 and having a 4-cyanophenyl substituent attached to the 2-amino group. NNRTI of HIV-1, binds directly to RT and blocks RNA-dependent and DNA-dependent DNA polymerase activities It has a role as a HIV-1 reverse transcriptase inhibitor and an antiviral agent. It is a dinitrile, an organobromine compound, an aminopyrimidine and an aromatic ether.|Etravirine is an antiretroviral agent more specifically classified as a Non-Nucleoside Reverse Transcriptase Inhibitor(NNRTI). Etraverine is used clinically for the treatment of human immunodeficiency virus type 1 (HIV-1) infection. On January 18, 2007, the FDA granted accelerated approved for the use of etravirine 100mg tablets in the treatment of adult HIV-1 infection documented to be resistant to therapy with other NNRTIs and antiretroviral agents. On March 26, 2012, approval was extended for use in treatment-experienced pediatric patients 6 to 18 years of age, weighing at least 16 kg. Etravarine must always be used in combination with other antiretroviral drugs. Etravirine exerts its effects via direct inhibition of the reverse transcriptase enzyme of human immunodeficiency virus type 1 (HIV-1), and consequently blocks DNA-dependent and RNA-dependent polymerase activity. Etravirine does not inhibit human DNA polymerase alpha, beta or gamma. Common side effects of use include mild to moderate rash within the first 6 weeks of therapy, nausea, diarrhea and peripheral neuropathy. Patients are advised to immediately contact their healthcare provider if a rash develops. In 2009, postmarketing case reports of Stevens-Johnson Syndrome, toxic epidermal necrolysis, erythema multiforme, and other hypersensitivity reactions lead to a revision of etravirine's "Warnings and Precautions," as well as notification of health care providers. In 2013, reports of Autoimmune disorders (such as Graves’ disease, polymyositis, and Guillain-Barré syndrome) in the setting of immune reconstitution, as well as more in depth information about the development of rashes in patients taking etravirine, lead to a modification of etravirine's monograph.|Etravirine is a Human Immunodeficiency Virus 1 Non-Nucleoside Analog Reverse Transcriptase Inhibitor. The mechanism of action of etravirine is as a Non-Nucleoside Reverse Transcriptase Inhibitor, and Cytochrome P450 3A Inducer, and Cytochrome P450 2C9 Inhibitor, and Cytochrome P450 2C19 Inhibitor, and P-Glycoprotein Inhibitor.|Etravirine is a nonnucleoside reverse transcriptase inhibitor used in combination with other agents in the therapy of human immunodeficiency virus (HIV) infection and the acquired immunodeficiency syndrome (AIDS). Etravirine has been associated with transient serum aminotransferase elevations and with hypersensitivity reactions that can be associated with liver injury including acute liver failure.|Etravirine is a diarylpyrimidine non-nucleoside reverse transcriptase inhibitor. Etravirine is designed to be active against HIV isolates with mutations that confer resistance to the two most commonly prescribed first-generation NNRTIs. It can bind the enzyme reverse transcriptase (RT) in multiple conformations, both for native and mutant RT, thereby blocking the enzymatic activity of RT.
