February 17, 2022 A simple mouth and nose spray could act as an effective shield to protect against COVID-19, adding one more tool to the arsenal of antiviral options. The straightforward solution was recommended by Dr. Mostafa Kamal Arefin of Dhaka Medical College & Hospital in Bangladesh and includes polyvinyl pyrrolidone or povidone iodine (PVP-I), a microbicidal agent with a virucidal efficacy of 99.99%. https://rumble.com/vnnoab-dr.-peter- mccullough-oralnasal-hygiene-for-sars-cov-2.html Writing in the Indian Journal of Otolaryngology and Head & Neck Surgery, Arefin recommended the PVP-I oro-nasal spray for health care workers and anyone else to help prevent COVID-19,2 echoing a number of other studies that have also found benefits to gargling, nasal irrigation and nebulization of PVP-I and other compounds, including Lugol’s iodine, saline and hydrogen peroxide.3 How Oronasal Sprays May Shield You From COVID-19 Arefin’s oronasal spray is made of a 0.6% PVP-I solution, kept in a “simple nasal spray device.” The spray formulation works better than drops, he noted, because it allows the active ingredient to diffuse further and reach deeper into the nose and nasopharynx, which is the upper part of the throat behind the nose. When applied, the oronasal spray acts as a protective layer, coating the nasal and oral mucosa. Typically, if you’re exposed to SARS-CoV-2, it will enter your body through your nose and mouth, remaining there for a time before binding with ACE2 receptors and entering cells. Once inside your cells, the virus has an opportunity to multiply. “The first step in the development of URTIs [upper respiratory tract infections],” Arefin writes, “is the adherence and colonization of the respiratory pathogen to the nasopharyngeal and oropharyngeal mucosa. Assuming nasal and oral entry of such pathogens, intranasal and intra oral application of Povidone Iodine offers a practical measure for their prevention.”4 By creating a protective shield, oronasal spray helps prevent SARS-CoV-2 from binding with ACE2 receptors and gaining entry into your cells. In a clinical trial that has not yet been published,5 Arefin and colleagues got positive results using 0.6% PVP-I Oro-nasal spray in 189 patients with COVID-19. The 0.6% solution had an efficacy rate of about 81.5%, which was greater than that of other concentrations (0.4% and 0.5%) and produced “almost no mucosal irritation.”6 Povidone-Iodine Inactivates SARS-CoV-2 Already, PVP-I gargles, throat sprays and nasal sprays are available over-the-counter in countries such as Japan and Canada.7 In Japan, a 0.45% PVP-I throat spray is available for the prevention of colds and sore throats, while gargling with the compound is part of their national respiratory guidelines.8 A 2002 study, during which patients were asked to gargle more than four times a day with a PVP-I solution, for several months up to two years, found the practice significantly reduced the incidence of chronic respiratory infections.9 In a preprint study that also advocated for the use of PVP-I nasal sprays and mouthwash to protect health care workers and reduce cross infection during the COVID-19 pandemic, it’s explained:10 “The antimicrobial action of PVP-I occurs after free iodine (I2) dissociates from the polymer complex. Once in the free form, iodine rapidly penetrates microbes and disrupts proteins and oxidizes nucleic acid structures. This interaction ultimately results in microbial death.” PVP-I has been found to be effective in-vitro against coronaviruses that caused the severe acute respiratory syndrome (SARS) epidemic of 2002 to 2003 and the Middle East respiratory syndrome (MERS) epidemic of 2012 to 2013.11 Povidone iodine solutions have also been found to inactivate SARS-CoV-2 in as little as 15 seconds12 and potentially reduce the carriage of infectious SARS-CoV-2 in people with mild to moderate COVID-19.13 In another study of nasal irrigation among high-risk patients with COVID- 19, the use of nasal irrigation with povidone iodine or baking soda reduced the risk of hospitalization by eight times compared to the national rate.14 In a letter to the editor of the Journal of Otolaryngology, Head & Neck Surgery, researchers further noted:15 “Because the reservoir for SARS-CoV-2 shedding is in the nasopharynx and nasal and oral cavities, the application of viricidal agents to these surfaces may reduce virus burden. Numerous studies have confirmed that povidone-iodine inactivates many common respiratory viruses, including SARS-CoV-1. Povidone-iodine also has good profile for mucosal tolerance. Thus, we propose a prophylactic treatment protocol for the application of topical povidone-iodine to the upper aerodigestive tract.” Benefits and How to Use PVP-I Oro-Nasal Spray Using 0.6% PVP-I Oro-nasal spray is low cost, safe and effective against coronaviruses, including SARS-CoV-2. It can be used both in healthy individuals as a protective agent and in people with COVID-19 to reduce viral load and the potential for transmitting the virus to close contacts. The side effects are minimal and include mucosal irritation, teeth staining and thyroid dysfunction. At least one study, which used both PVP-I mouthwashes and gargles four times a day for five days, found an elevation in thyroid stimulating hormone during treatment, but levels returned to normal after the treatment was stopped.16 Arefin recommends the spray for both health care workers and the general population, prior to attending public gatherings or working outside the home, and following exposure to a suspected COVID-19 patient. He advises two to three puffs in each nostril and one to three puffs in the throat every three to four hours. After every one to two weeks of use, he recommends taking a one-day break from the treatment.17 There are, however, many ways to use nasal irrigation, gargles and nebulization against COVID-19. For instance, Dr. Peter McCullough, an internist, cardiologist and epidemiologist, tweeted, “Nasal/oral viricidal washes can be done prophylactically twice a day and up to every 4 hours during early treatment. Reduce viral load for less severe illness.”18 The Front Line COVID-19 Critical Care Working Group (FLCCC) also recommends povidone-iodine as part of their I-Mask+ protocol for prevention and early outpatient treatment of COVID-19. Part of their prevention protocol includes twice daily gargling with a 1% povidone/iodine solution, while iodine nasal spray or drops are recommended as one of the first line agents in their early treatment protocol. Specifically, they recommend:19 “Use 1 % povidone-iodine commercial product as per instructions 2–3 x daily. If 1 %-product not available, must first dilute the more widely available 10 %-solution and apply 4–5 drops to each nostril every 4 hours. (No more than 5 days in pregnancy.)” Importantly, povidone-iodine solutions sold as topical skin disinfectants to treat cuts and wounds should not be used for gargling due to potentially harmful ingredients. Proper Dilution Is the Key to Safety Povidone-iodine gargles and nasal sprays, and nebulized peroxide diluted with saline, with or without iodine, can be safely used by most people both for prevention and in cases of active infection, provided the substances are properly diluted. For instance, while nebulization with 0.1% to 3% hydrogen peroxide appears to be quite safe, it would be a very serious hazard to use peroxide of greater concentrations. Food grade peroxide up to 35% concentration can be obtained but should NEVER be used topically or internally. It MUST be diluted or severe injury can occur. Your safest bet is to use 3% food grade peroxide and dilute it as indicated in the chart provided below so you end up with a solution of 0.1%. Post Comment Private Reply Ignore Thread
