Use of Bromhexine and Hydroxychloroquine for Treatment of COVID-19 Pneumonia

Use of Bromhexine and Hydroxychloroquine for Treatment of COVID-19 Pneumonia

In the current situation it is of great importance to discover a safe, cost-effective and available treatment strategy in order to limit the rapidly spreading SARS-Cov-2. Recent studies have shown that hydroxychloroquine could have a role in the treatment of infected patients. It is however not very likely that hydroxychloroquine alone could be adequate for treatment of Covid-19 disease. Effective therapy that prevents the virus entrance should contain at least TMPRSS2 inhibitor or a competitive inhibitor of viral ACE 2 binding. The use of bromhexine at the dose adequate to selectively inhibit the TMPRSS2, resulting in preventing of viral entrance via TMPRSS2-specific pathway, coud be an effective treatment of Covid-19. In our study we would like to explore the therapeutic potential of bromhexin and hydroxychloroquine in Covid-19 patients.

Hypothesis

1. Combined treatment with bromhexin and hydroxychloroquine shortens the course of disease in hospitalized Covid-19 patients compared to hydroxychloroquine alone.
2. Combined treatment with bromhexin and hydroxychloroquine lowers the incidence of secundary pulmonary infections in hospitalized Covid-19 patients compared to hydroxychloroquine alone.
3. Combined treatment with bromhexin and hydroxychloroquine decreases the need for ICU admission in hospitalized Covid-19 patients compared to hydroxychloroquine alone.
