Olgotrelvir
Olgotrelvir (STI-1558) is an experimental antiviral medication being studied as a potential treatment for COVID-19. It is believed to work by inhibiting the SARS-CoV-2 main protease (Mpro), a key enzyme that SARS-CoV-2 needs to replicate, and by blocking viral entry. Mechanism of action Olgotrelvir is a prodrug that first converts to its active form, AC1115. AC1115 is believed to work by inhibiting the SARS-CoV-2 main protease (also known as 3C-like protease). This protein is a crucial enzyme responsible for cleaving viral polyproteins into functional subunits essential for viral replication. By binding to the active site of the protease, the drug prevents this cleavage process, effectively halting viral assembly and impeding the virus's ability to produce future virions. Olgotrelvir also appears to inhibit cathepsin L (CTSL), a protein implicated in facilitating viral entry Viral entry is the earliest stage of infection in the viral life cycle, as the virus comes into conta ...

By Mouth
Oral administration is a route of administration whereby a substance is taken through the Human mouth, mouth, swallowed, and then processed via the digestive system. This is a common route of administration for many medications. Oral administration can be easier and less painful than other routes of administration, such as Injection (medicine), injection. However, the onset of action is relatively low, and the effectiveness is reduced if it is not absorbed properly in the digestive system, or if it is broken down by digestive enzymes before it can reach the bloodstream. Some medications may cause gastrointestinal side effects, such as nausea or vomiting, when taken orally. Oral administration can also only be applied to conscious patients, and patients able to swallow. Terminology ''Per os'' (; ''P.O.'') is an adverbial phrase meaning literally from Latin "through the mouth" or "by mouth". The expression is used in medicine to describe a treatment that is taken orally (but not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
