New study shows lozenges can help fight COVID-19

Over-the-counter lozenges have been a go-to relief for people experiencing early signs of sore throat and to manage pesky colds or coughs. A recent study claims that some OTC throat lozenges may also be effective against COVID-19.

Researchers at Microbiology and Immunology Institute of the University of Ljubljana in Slovenia, found that throat lozenges containing a combination of Benzydamine Hydrochloride (BH) and Cetylpyridinium Chloride (CPC) may have a virucidal effect against Covid-19 and help reduce the risk of viral transmission.

The results of this study were first published by Andrej Steyer, Misa Marusic, Marko Kolenc, Tina Triglav from the Faculty of Medicine, Institute of Microbiology and Immunology, University of Ljubljana, Slovenia, in the article “A throat lozenge with fixed combination of cetylpyridinium chloride and benzydamine hydrochloride has direct virucidal effect on SARS-CoV-2”, COVID, 2021;1(2):435-446 (Available from: ) which has since been republished with permission in the Romanian Journal of Pharmaceutical Practice (Sarafoleanu C et al, 2021).

According to their preliminary findings, which were based on testing in a defined and controlled laboratory environment designed to mimic the conditions of the oral cavity, certain throat lozenges have virus-killing properties that can fight SARS-CoV-2, the virus responsible for COVID-19 infection.

In fact, the throat lozenges that have a high concentration of BH and CPC were the fastest at destroying the virus, reducing the viral concentration by 99.99% in as fast as 1 (one) minute. This also suggests the possibility of reducing the amount of virus in the oral cavity as well as reducing the risk of viral transmission.

While this study is yet to be peer-reviewed, it is an encouraging step in the battle against Covid-19.

Especially as economic activities start to reopen with the country downgrading its restriction status to Alert Level 1, these results are extremely encouraging and are a welcome positive step in finding ways to manage the spread of COVID-19.

Of course, getting vaccinated with booster shots and the observance of standard health protocols such as proper handwashing, physical distancing, and mask-wearing are still the most effective ways to help curb the spread of COVID-19.

But through a simple and effective method such as using widely available medicated sore throat lozenges with Benzydamine Hydrochloride and Cetylpyridinium Chloride contents, people can at least add a layer of security for themselves.
