This study is a multi-center, randomized, double blinded, prospective, placebo controlled study. Patients upon diagnosis of COVID-19 (Corona Virus Disease-19) will be eligible to participate in the study. The purpose of this study is to find out the side effects and ability to take the study drug, Nitric Oxide (NO) lozenges when taken twice daily by mouth.
