This conditional early approval system has previously been used in Japan to accelerate the progression to market of other antiviral drugs targeting COVID-19, including remdesivir and molnupiravir. [13] In a study of 428 patients, viral load was reduced, but symptoms were not significantly reduced. [14]
[2] [16] A dynamic, systematic review was established in April 2020 to track the progress of registered clinical trials for COVID-19 vaccine and therapeutic drug candidates. [12] Drug development is a multistep process, typically requiring more than five years to assure safety and efficacy of the new compound. [17]
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.
Most antivirals target specific viruses, while a broad-spectrum antiviral is effective against a wide range of viruses. [2] Antiviral drugs are a class of antimicrobials, a larger group which also includes antibiotic (also termed antibacterial), antifungal and antiparasitic drugs, [3] or antiviral drugs based on monoclonal antibodies. [4]
If taking Paxlovid, some side effects, according to the treatment’s fact sheet, could include allergic reactions, liver problems, nausea, high blood pressure, altered sense of taste and ...
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.
Researchers at Boston’s Dana-Farber Cancer Institute are working on a drug that takes one of the virus’s most dangerous traits — its talent for mutation — and turns it back on itself.
