Figure 3 Proposed mechanistic pathways of proton pump inhibitors in coronavirus disease 2019: Illustration hypothesizing the potential biological effects of chronic proton pump inhibitor use in coronavirus disease 2019. Mechanisms include reduction of lysosomal acidification, attenuation of inflammatory cytokine release, mitigation of pulmonary oxidative stress, and enhancement of antiviral drug activity, ultimately leading to decreased disease severity. PPI: Proton pump inhibitors; COVID-19: Coronavirus disease 2019.
