HCQ for COVID-19
1st treatment shown to reduce risk in March 2020
 
*, now known with p < 0.00000000001 from 422 studies, recognized in 42 countries.
No treatment is 100% effective. Protocols combine complementary and synergistic treatments. * >10% efficacy in meta analysis with ≥3 clinical studies.
4,000+ studies for 60+ treatments. c19hcq.org
In Vitro study showing that CatB inhibitors including nitroxoline and its derivatives significantly impair SARS-CoV-2 infection. Authors use HCQ as a control. HCQ can indirectly inhibit CatB by elevating the pH of endosomes. Other research shows that SARS-CoV-2 infection requires acidic pH Kreutzberger.
Milan Bonotto et al., 30 Jun 2023, peer-reviewed, 8 authors. Contact: janko.kos@ffa.uni-lj.si, marcello@icgeb.org.
In Vitro studies are an important part of preclinical research, however results may be very different in vivo.
