Analysis: The New Pfizer Drug PAXLOVID™ vs. Ivermectin

I recently picked up an Ivermectin prescription from a local compounding pharmacy after my doctor described it for my use in case I come down with COVID-19. To increase my resistance against the virus, I also follow the daily regimen below.

It is not hard to see that Big Pharma along with the NIH, CDC, medical associations, and the mainstream media have put forth an all-out effort to suppress the truth about the effectiveness of Ivermectin.

The American Journal of Therapeutics document titled, “Ivermectin for Prevention and Treatment of COVID-19 Infection: A Systematic Review, Meta-analysis, and Trial Sequential Analysis to Inform Clinical Guidelines” concludes as follows:

Given the evidence of efficacy, safety, low cost, and current death rates, Ivermectin is likely to have an impact on the health and economic outcomes of the pandemic across many countries.

Ivermectin is not a new and experimental drug with an unknown safety profile. It is a WHO “Essential Medicine” already used in several different indications, in colossal cumulative volumes.

Corticosteroids have become an accepted standard of care in COVID-19, based on a single RCT of dexamethasone. If a single RCT is sufficient for the adoption of dexamethasone, then a fortiori the evidence of 2 dozen RCTs supports the adoption of Ivermectin.

Ivermectin is likely to be an equitable, acceptable, and feasible global intervention against COVID-19.

Health professionals should strongly consider its use, in both treatment and prophylaxis.

So, what is a protease?

So what is a protease inhibitor?

And, what is 3CL?

Chymotrypsin-like protease (3CL main protease, or 3CL Mpro)

Identification of SARS-CoV‑2 3CL Protease Inhibitors by a Quantitative High-Throughput Screening (3rd September 2020) https://pubs.acs.org/doi/abs/10.1021/…

The activity of the anti-SARS-CoV-2 viral infection was confirmed in 7 of 23 compounds

Microscopic interactions between ivermectin and key human and viral proteins involved in SARS-CoV-2 infection https://pubs.rsc.org/en/content/artic…

The strength and persistency of the interaction between IVE and the binding site of 3CLpro indicate that a partial inhibition of the catalytic activity could have a place as the drug interacts with the main subdomains that define the enzyme binding pocket:

As shown in Fig. 4, out of 13 OTDs only ivermectin completely blocked ( more than 80%) the 3CLpro activity at 50 µM concentration.

Development, validation, and approval of COVID-19 specific drugs takes years. Therefore, the idea of drug repositioning, also known as repurposing, is an important strategy to control the sudden outbreak of life-threatening infectious agents that spread rapidly.

Molecular Docking Reveals Ivermectin and Remdesivir as Potential Repurposed Drugs Against SARS-CoV-2 https://www.frontiersin.org/articles/… With SARS-CoV-2 S Spike protein

Ivermectin showed a high binding affinity to the viral S protein as well as the human cell surface receptors ACE-2 and TMPRSS2.

In agreement with our findings, ivermectin was found to be docked between the viral spike and the ACE2 receptor
