Nitazoxanide/azithromycin combination for COVID-19: A suggested new protocol for early management.

ABSTRACT

Azithromycin has been shown to have a clinical efficacy against severe acute respiratory syndrome coronavirus 2; ivermectin has also demonstrated a remarkable experimental efficacy with a potential to be used for Coronavirus disease 2019. Further, BCG vaccination is being considered for clinical trials aiming to test its potential for lowering COVID-19 morbidity and mortality. This article illustrates some structural and functional relationships that may gather these drugs and the author, basing on a combined pathophysiological and pharmacological approach, recommends the FDA-approved antidiarrhea drug; nitazoxanide, which has been previously suggested but unfortunately widely ignored, to be tested in combination with azithromycin for their potential activity against SARS CoV-2, soonest. The author also recommends testing their combined administration as early during the clinical course of COVID-19 as possible. Further, basing on the same represented concept, the author suggests more trials for interferons to be tested against SARS CoV-2, especially in severe and critical COVID-19 cases.
