The most severe manifestations of COVID-19 include respiratory failure, coagulation problems, and death. Inflammation and blood clotting are believed to play an important role in these manifestations. Research in humans has shown that dipyridamole can reduce blood clotting. This research study is being conducted to learn whether 14 days of treatment with dipyridamole will reduce excessive blood clotting in COVID-19. This study will enroll participants with confirmed coronavirus (SARS-CoV)-2 infection that are admitted. Eligible participants will be randomized to receive dipyridamole or placebo for 14 days in the hospital. In addition, data will be collected from the medical record, and there will also be blood draws during the hospitalization.
Drug: Dipyridamole 100 Milligram(mg)
Drug will be given for 14 days while in the hospital.
Drug: Placebo oral tablet
Placebo will be given for 14 days while in the hospital.

- History of recent major bleeding, defined in accordance with the criteria of the
International Society on Thrombosis and Hemostasis (ISTH).
- Any physical examination findings and/or history of any illness that, in the opinion
of the study investigator, might confound the results of the study or pose an
additional risk to the patient by their participation in the study
