Experimental: Test group 1
Nitroketazine tablet 600 mg group
|
Drug: Nitrofurazone Group 1
Test group 1: Nitroketazine tablet 600 mg group (Nitroketazine 300 mg tablet X2 + placebo 300 mg tablet ×2 tablets each time; If the subject progresses and cannot take 300mg tablets, Nitroketazine 100mg tablets x6 + placebo 100mg tablets x6) can be replaced. |
Experimental: Test group 2
Nitroketazine tablets 1200 mg group
|
Drug: Nitroketazine Group 2
Test group 2: Nitroketazine tablets 1200 mg group (each oral Nitroketazine 300 mg tablets x4 tablets; If the subject progresses and cannot take 300 mg tablets, Nitroketazine 100mg tablets x12 tablets can be taken instead). |
