Efficacy of Three Antimicrobial Mouthwashes in Reducing SARS-CoV-2 Viral Load in the Saliva of Patients Diagnosed With COVID-19: A Pilot Study
In Brief
A clinical study evaluating Corsodyl® Alcohol free -0.2 % Chlorhexidine digluconate, Colgate Peroxyl® -1.5% Hydrogen peroxide, and 2 other interventions for Covid19 and Coronavirus. Completed, enrolled 54 participants across 2 sites.
Detailed Summary
This is a single-blind, parallel-group, randomized pilot study designed to evaluate and compare the efficacy of 3 different mouthwashes containing 0.2% Chlorhexidine digluconate, 1.5% Hydroxide peroxide or Cetylpyridinium chloride in reducing Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral load in the saliva of COVID-19 positive patients at different time-points. A convenient sample of up to 40 COVID-19 positive patients diagnosed via test and/or presenting COVID-19 clinical symptoms will be identified in the inpatients and/or outpatient clinics at the Newham University Hospital and at The Royal London Hospital, Barts Health National Health Service (NHS) Trust, United Kingdom (UK). The study will consist of one visit. Unstimulated saliva samples will be collected from all COVID-19 positive patients before and at 30 minutes, 1, 2, and 3 hours after mouth rinsing (Group 1-3 ) or no rinsing (Group 4). Viral load analysis of saliva samples in the different time-points will be then assessed by Reverse Transcription quantitative PCR (RT- qPCR).

Interventions
Corsodyl® Alcohol-free is a clear to slightly opalescent oromucosal solution with an odour of peppermint that contains 0.2% w/v chlorhexidine digluconate which is an antimicrobial preparation for external use. It is effective against a wide range of Gram negative and Gram positive vegetative bacteria, yeasts, dermatophyte fungi and lipophilic viruses. It is active against a wide range of important oral pathogens and is therefore effective in the treatment of many common oral conditions.
Peroxyl mouthwash is a clear aqua-blue liquid oromucosal solution which 100ml of solution contains 1.5g of Hydrogen peroxide (as 30% Hydrogen Peroxide solution). It is an oral antiseptic cleanser for external use. The principal action is brought about by contact of hydrogen peroxide with peroxidases and catalases present in tissues and saliva, which causes the rapid release of oxygen. This provides mechanical cleansing which flushes out mouth debris and helps in the treatment of oral irritations. This mouthwash is used as a cleanser in the symptomatic relief of minor mouth and gum irritations.
The Oral-B® Gum \& Enamel Care mouthwash is an oromucosal solution containing Cetylpyridinium chloride (CPC) and used as an adjunct to oral hygiene.
No rinsing
