Ensitrelvir is being studied for its potential use as post-exposure prophylaxis (PEP) after SARS-CoV-2 exposure. [19] [20] The SCORPIO-PEP trial is a global Phase 3 trial that will evaluate the safety and efficacy of the drug in preventing symptomatic SARS-CoV-2 infection in household contacts of people who tested positive for COVID-19.
The general idea behind modern antiviral drug design is to identify viral proteins, or parts of proteins, that can be disabled. [11] [13] These "targets" should generally be as unlike any proteins or parts of proteins in humans as possible, to reduce the likelihood of side effects and toxicity. [8]
The drug was also shown to reduce the viral load at day 4 in treated patients compared to the placebo group. Side effects were mostly mild and infrequent, with the most common being nausea (1.5% vs. 0.2%) and skin rash (3.3% vs. 0.3%), which occurred more often in the olgotrelvir group.

Nirmatrelvir is an antiviral medication developed by Pfizer which acts as an orally active 3C-like protease inhibitor .
Nelfinavir belongs to the class of drugs known as protease inhibitors (PIs) and like other PIs is almost always used in combination with other antiretroviral drugs. Nelfinavir is an orally bioavailable human immunodeficiency virus HIV-1 protease inhibitor (K i = 2 nM) and is widely prescribed in combination with HIV reverse transcriptase ...

Maribavir, sold under the brand name Livtencity, is an antiviral medication that is used to treat post-transplant cytomegalovirus (CMV). [8] [9] Maribavir is a cytomegalovirus pUL97 kinase inhibitor that works by preventing the activity of human cytomegalovirus enzyme pUL97, thus blocking virus replication.
Nevirapine in triple combination therapy has been shown to suppress viral load effectively when used as initial antiretroviral therapy (i.e., in antiretroviral-naive patients). [8] Some clinical trials have demonstrated comparable HIV suppression with nevirapine-based regimens to that achieved with regimens based on a protease inhibitor (PI ...
