COVID-19 and Phosphodiesterase Enzyme Type 5 Inhibitors

Hayder M Al-Kuraishy et al. J Microsc Ultrastruct. .

Abstract

COVID-19 pathology is mainly associated to a pulmonary disease which sometimes might result in an uncontrollable storm related to inflammatory diseases which could be fatal. It is well known that phosphodiesterase enzyme type 5 inhibitors (PDE5Is), such as sildenafil, have been successfully developed for the treatment of pulmonary arterial hypertension; interestingly, more recently, it was shown that PDE5Is might be also anti-inflammatory. Therefore, it would be of interest to question about the use of PDE5Is to overcome the COVID-19 storm, as much as PDE5 is mainly present in the lung tissues and vessels.

Keywords: Acute lung injury; COVID-19; nucleotide phosphodiesterase enzyme.
