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]
A drug combination targeting SARS-CoV-2, Paxlovid, was approved in December 2021 to treat COVID-19. [12] It is a combination of nirmatrelvir , a protease inhibitor targeted to the SARS-CoV-2 3C-like protease , and ritonavir, which inhibits the metabolism of nirmatrelvir, thereby prolonging its effect.
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.
Nirmatrelvir/ritonavir is under investigation, so its side effects have yet to be fully evaluated and may not be completely known. [ 19 ] Other side effects of nirmatrelvir/ritonavir may include hypersensitivity reactions , liver toxicity , and development of HIV drug resistance in people with uncontrolled or undiagnosed HIV infection .
Ritonavir is indicated in combination with other antiretroviral agents for the treatment of HIV-1-infected patients. [4] [5] [8] Though initially developed as an independent antiviral treatment, it is most commonly used as a pharmacokinetic enhancer, in order to increase the plasma concentrations of other antiretrovirals.

The majority of people who use entecavir have little to no side effects. [13] The most common side effects include headache, fatigue, dizziness, and nausea. [3] Less common effects include trouble sleeping and gastrointestinal symptoms such as sour stomach, diarrhea, and vomiting. [14] Serious side effects from entecavir include lactic acidosis ...
[42] [43] Neuropsychiatric symptoms and body pain, followed by skin problems, were identified as the side effects most significantly reducing patient satisfaction on a drug review platform. [44] The US and EU package inserts for oseltamivir contain a warning of psychiatric effects observed in post-marketing surveillance.
