About this trial

The goal of this clinical trial is to learn if troxerutin works to prevent thrombotic events in mild or severe COVID-19 patients. It will also learn about the safety of troxerutin. The main questions it aims to answer are:

* Does troxerutin lower the number of thrombotic events in participants? * What medical problems do participants have when taking troxerutin? Researchers will compare troxerutin to a placebo (a look-alike substance that contains no drug) to see if troxerutin works to prevent thrombotic events in COVID-19 patients.

Participants will:

* Take troxerutin or a placebo every day for 7 days. * Visit the clinic at the first, fourth, seventh and 28th days after enrollment for checkups and tests * Keep a diary of their symptoms and the number of times of thrombotic events, bleeding events and type II HIT-related thrombocytopenia

Trial outcomes

Primary outcomes

1

Overall number of patients in prothrombotic state through 7 days

Assess coagulation-related parameters in patients' blood, including platelet count, prothrombin time (PT), antithrombin III activity (ATIIIa), plasma fibrinogen concentration (Fbg), and quantitative D-dimer.Patients with one or more indicators in the abnormal range, including PT \< 11s (reference interval: 11-14 s), FG \> 4g/L (reference interval: 2-4 g/L), D-dimer \< 0.5 μg/mL (reference interval: 0-0.5 μg/mL), are considered in a prothrombotic state.
