The mendacity and greed of big pharma ( yes I mean you Pfizer with your overpriced products ) never ceases to amaze me. There is an existing anti-viral drug available for £0.05 per dose and Pfizer come up with a much less effective one for an eye watering £340 per dose... the difference is that Ivermectin is out of patent ( so not much money to be made ) but Pfizer have dreamed up a similar but less broadly acting one that they can patent and make huge profits out of gullible governments for the next 20 years. Would not surprise me to find out that Pfizer were funding Wuhan lab to make a virus that they were already working on a vaccine for - loadsa money.....
Beware cheap untested wonder cure promoted by right wing organisations.
Ivermectin is an antiparasitic medication.[6][7] Parasitic infestations in humans include head lice, scabies, river blindness (onchocerciasis), strongyloidiasis, trichuriasis, ascariasis, and lymphatic filariasis.[6][8][9][10] In veterinary medicine, the medication is used to prevent and treat heartworm and acariasis, among other indications.[9] Ivermectin works through many mechanisms of action that result in the death of the targeted parasites;[6] it can be taken by mouth or applied to the skin for external infestations.[6][11]
During the COVID-19 pandemic, misinformation has been widely spread claiming that ivermectin is beneficial for treating and preventing COVID-19.[20][21] Such claims are not backed by credible scientific evidence.[22][23] Research into its use is ongoing, and multiple major health organizations, including the Food and Drug Administration, U.S. Centers for Disease Control, the European Medicines Agency, and the World Health Organization have stated that ivermectin is not authorized or approved to treat COVID-19.

https://www.theguardian.com/science/2021/jul/16/huge-study-supporting-ivermectin-as-covid-treatment-withdrawn-over-ethical-concernsThe health authorities in the US, UK and EU have found there is insufficient evidence for using the drug against Covid, but thousands of supporters, many of them anti-vaccine activists, have continued to vigorously campaign for its use.
https://www.bbc.co.uk/news/health-58170809I must admit I didn't watch all the video or understand much of what I watched but I found the demonstration with scissors and sellotape unconvincing.
The structures of the two drugs he was comparing were completely different and just because the two structures had functional groups in common did not mean that the drugs would have the same effect.
What other effects might the other parts of the structures have?
Edit Just spent the last half hour watching his next video on checking the fact checkers and I'm still not convinced
