Drug-durg Interaction of ZSP1273 With Digoxin, Rosuvastatin,Itraconazole and Probenecid

A Open-Label, Two-sequence Phase I Drug-drug Interaction Clinical Study to Investigate the Pharmacokinetics of ZSP1273 With Digoxin, Rosuvastatin,Itraconazole and Probenecid in Healthy Participants

The drug-drug interaction study had been designed to investigate the effect of ZSP1273 on the pharmacokinetics of digoxin, Rosuvastatin and the effect of Itraconazole and Probenecid on the pharmacokinetics of ZSP1273

3. Smoking more than 5 cigarettes per day within 3 months prior to screening，or who cannot stop using any tobacco products during the study period;
4. Participants who donated blood/bleeding profusely (> 400 mL) 3 months prior to randomization;
5. Those with clinically significant Electrocardiogram(ECG) abnormalities, or QTcF > 450ms;
6. Participants who test positive at screening for human immunodeficiency virus (HIV), Hepatitis B surface antigen (HBsAg), Hepatitis C virus (HCV) antibody or Syphilis spirochete-specific antibodies (TPPA);
7. Participants who test positive at Screening and/or admission (Day -1) for alcohol abuse.
