2. Aged 18-45 years (inclusive), healthy male or female;
3. Male weight ≥ 50 kg, female weight ≥ 45 kg, and body mass index (BMI): 19-26 kg/m2 (inclusive), body mass index (BMI) = weight (kg)/(height/100)2 (m2);
4. Physical examination, vital signs, 12-lead electrocardiogram, chest anteroposterior and lateral radiographs, abdominal ultrasound and laboratory tests during the screening and baseline periods were normal, or slightly abnormal but clinically insignificant as determined by the researchers;
5. Female subjects with fertility and male subjects whose partners are women of childbearing age have taken contraceptive measures within 2 weeks before signing the informed consent form, and are willing to abstain from sex or agree to contraception from the signing of the informed consent form until the end of the follow-up period (non-drug contraception is required during the trial, see Section 13.1.2 for details), and have no plans to have children or donate sperm/eggs.

Exclusion Criteria

The following diseases or treatment history:

1. Any serious clinical diseases such as urinary system, circulatory system, endocrine system, nervous system, digestive system, respiratory system, blood system, immune system, mental and metabolic disorders in the past or currently, or any other diseases that the investigators judge may interfere with the results of the trial, such as intestinal diseases (including irritable bowel syndrome) and urinary tract infection/stones, etc.;

2. History of malignant tumors (cancers that have been confirmed to have been cured or relieved for ≥5 years, except for radically resected basal cell or squamous cell skin cancer, cervical cancer in situ and resected colon polyps);

3. Any conditions or diseases that affect the absorption, metabolism and/or excretion of the study drug;

4. Severe infection, severe trauma or major surgery within 3 months before the screening period or baseline period; or plan to undergo surgery during the trial;

5. Have used any drug in the 2 weeks before the screening or baseline period (including prescription drugs, over-the-counter drugs, Chinese herbal medicines, dietary supplements, vitamin A and its derivatives, etc., excluding other conventional vitamins and occasional use of acetaminophen), or still within 5 half-lives of the drug during the screening or baseline period (whichever is longer); plan to use non-test drugs during the trial;

6. Participated in clinical trials of any other drugs or medical devices within 3 months before the screening or baseline period or planned to participate in the study period, or still within 5 half-lives of the drug during the screening or baseline period (whichever is longer);

   Any of the following examinations during screening meet the following criteria:

7. During the screening or baseline period, sitting systolic blood pressure <90 mmHg or sitting diastolic blood pressure <60 mmHg;

8. During the screening or baseline period, orthostatic hypotension occurs (retest within 15 minutes to confirm);

9. During the screening or baseline period, abnormal and clinically significant 12-lead electrocardiogram results, male QTcB>450ms, female QTcB>460ms;

10. During the screening or baseline period, serum creatinine exceeding the upper limit of normal (ULN);

11. During the screening or baseline period, eGFR < 70 mL/min/1.73m2 (calculated using the MDRD formula, eGFR (mL/min/1.73m2) = 175×(serum creatinine/88.4)-1.234×age-0.179×(0.79 female), where serum creatinine units are μmol/L);

12. During the screening or baseline period, alanine aminotransferase (ALT) or aspartate aminotransferase (AST) exceeding 1.2 times ULN, or total bilirubin exceeding 1.5 times ULN;

13. During the screening period, any one of the following items is positive: hepatitis B virus surface antigen (HBsAg), human immunodeficiency virus antibody, syphilis spirochete antibody or hepatitis C virus antibody;

    General situation:

14. Pregnant or lactating women, or positive pregnancy test results during the screening period/baseline period;

15. History of blood donation or severe blood loss (blood loss ≥400 mL) within 8 weeks before the screening period or baseline period, or have received blood transfusion within 4 weeks before the screening period or baseline period; or intend to donate blood during the trial;
