Summary of COVID-19 phthalocyanine studies


1. da Silva Santos et al., Beneficial effects of a mouthwash containing an antiviral phthalocyanine derivative on the length of hospital stay for COVID-19: randomised trial
41 patient phthalocyanine late treatment RCT: 85% lower mortality (p=0.23), 92% lower ICU admission (p=0.02), and 54% lower hospitalization (p=0.03).
RCT 41 patients in Brazil, 20 treated with a phthalocyanine derivative mouthwash, showing shorter hosptalization and lower ICU admission with treatment. One minute gargling/rinsing 5 times per day.

2. Colado Simão et al., Effect of phthalocyanine oral and nasal antiseptic solutions on the infectivity of SARS-CoV-2 in patients with COVID-19: a randomized controlled trial
75 patient phthalocyanine late treatment RCT: 51% improved viral clearance (p=0.008).
RCT 75 patients in Brazil, showing significantly lower viral load with phthalocyanine mouthwash and nasal spray. The combination was more effective than mouthwash alone.

3. Poleti et al., Use of mouthwash and dentifrice containing antimicrobial phthalocyanine derivative for the reduction of clinical symptoms of COVID-19: A randomized triple-blinded clinical trial
134 patient phthalocyanine early treatment RCT: 29% improved recovery (p=0.02).
RCT 500 patients in Brazil, showing improved recovery with a phthalocyanine derivative mouthwash and toothpaste. Toothbrushing for 2 minutes, three times per day, and gargling/rising (5ml) for one minute, three times a day, for 7 days.

4. Brito-Reia et al., Population-based virucidal phthalocyanine gargling/rinsing protocol to reduce the risk of coronavirus disease-2019: a community trial
5,040 patient phthalocyanine prophylaxis study: 54% fewer cases (p=0.08).
Comparison of two similar communities in Brazil, with one using a phthalocyanine derivative mouthwash, suggesting efficacy of the treatment in lowering COVID-19 cases. There was 54% lower risk of confirmed cases during the intervention in the treatment community, compared with 15% higher and 8% lower risk before and after the intervention. Gargle/rinse with 5mL of mouthwash containing phthalocyanine derivative for 1 minute, 3 to 5 times per day.
