The viral DNA is then integrated into the host chromosomal DNA, nnrti full form, which then allows host cellular processes, such as transcription and translation, to reproduce the virus. RTIs block reverse transcriptase's enzymatic function and prevent completion of synthesis of the double-stranded viral DNA, thus preventing HIV from multiplying. A similar process occurs with other types of viruses.

The currently available NNRTIs are nevirapine, delavirdine, and efavirenz; other compounds are under evaluation. NNRTIs are extensively metabolized in the liver through cytochrome P, leading to pharmacokinetic interactions with compounds utilizing the same metabolic pathway, particularly PIs, whose plasma levels are altered in the presence of NNRTIs. NNRTIs are drugs with a low genetic barrier, i. However, due to the rapid emergence of resistant virus to these compounds in case of incomplete viral suppression, NNRTIs should not be added to current failing antiretroviral regimen. The most common side-effect reported with nevirapine and delavirdine is rash. The incidence of rash is rather similar under these two compounds, but severe rash is less frequent with delavirdine. The most common adverse reactions reported with efavirenz are central nervous system complaints such as dizziness. Rash is reported less frequently than with nevirapine or delavirdine, and is usually mild. High-level resistance is often associated with a single point mutation which develops within this site especially codon groups - and - NNRTIs should always be used as part of a potent antiretroviral therapy to insure suppression of viral replication, thus circumventing the rapid selection of cross-resistant variants.

This review describes recent clinical data, pharmacokinetics, metabolism, pharmacodynamics, safety and tolerability of commercialized NNRTIs, including the effects of sex, race and age differences on pharmacokinetics and safety. This review presents a wide description of NNRTIs, providing useful information for researchers interested in this field, both in clinical use and in research. Infections with the human immunodeficiency virus HIV are typically treated with drug combinations consisting of at least three different antiretroviral drugs.

RT is one of the most popular targets in the field of antiretroviral drug development. Discovery and development of NNRTIs began in the late s [2] and in the end of four NNRTI had been approved by regulatory authorities and several others were undergoing clinical development. Acquired immunodeficiency syndrome AIDS is a leading cause of death in the world. In the year over 40 million people were infected worldwide with HIV and the number keeps on growing. The drugs belong to six different classes that act at different targets. The most popular target in the field of antiretroviral drug development is the HIV-1 reverse transcriptase RT enzyme. In , the first drug for the treatment of HIV infection was approved by the U. This was the NRTI called zidovudine. The development of NNRTIs improved quickly into the s and they soon became the third class of antiretroviral drugs, following the protease inhibitors.

After achieving these goals, CD4 count measuring can cease. Monitoring mainly takes place through assessments like CD4 count and viral load. NNRTIs do not bind to the active site of the polymerase but in a less conserved pocket near the active site in the p66 subdomain. This phosphorylation step is carried out by cellular kinase enzymes. When the viral load becomes undetectable, it means that the drug regimen that the patient is on is working at maximum efficacy. Their binding results in a conformational change in the reverse transcriptase that distorts the positioning of the residues that bind DNA, inhibiting polymerization. Similar articles in PubMed.
