- •Female participants of childbearing potential must have a negative serum pregnancy test within 7 days prior to randomization and must not be breastfeeding; female participants of childbearing potential must use highly effective contraceptive measures (see Appendix 13.1.2) from 30 days prior to the screening period until 6 months after the last dose, and have no plans for egg donation or pregnancy; male participants with a female partner of childbearing potential must use highly effective contraceptive measures from the time of signing the informed consent form until 6 months after the last dose.
排除标准
- •Patients with a history of vestibular disorders (including but not limited to: peripheral vestibular syndrome, central vestibular syndrome, etc.) or dizziness (excluding history of motion sickness), or a history of central nervous system disorders that may cause nausea and vomiting;
- •History of chronic nausea or vomiting/retching;

- •Any other medical condition that, in the investigator's judgment, may confound the assessment of postoperative nausea and/or vomiting.
- •Random blood glucose > 11.1 mmol/L during the screening period;
- •Prolonged QTc interval during the screening period: > 450 ms in males, > 470 ms in females;
- •Systolic blood pressure ≥ 160 mmHg or < 90 mmHg, and/or diastolic blood pressure ≥ 100 mmHg or < 60 mmHg from the time of signing the ICF to before entering the operating room, which is considered clinically significant by the investigator;
- •Abnormal liver function during the screening period: aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) and/or gamma-glutamyl transferase (GGT) ≥ 3.0 × ULN and/or total bilirubin (TBIL) ≥ 1.5 × ULN;
- •Abnormal renal function during the screening period: serum creatinine (Cr) ≥ 1.5 × ULN and/or participants undergoing dialysis;
- •Positive test for hepatitis B surface antigen (HBsAg), hepatitis C antibody (HCVAb), syphilis antibody, or human immunodeficiency virus (HIV) antibody during the screening period;

- •Participants whose last use of an opioid occurred less than 5 half-lives before the start of investigational product administration;
- •Use of strong CYP3A4 inducers, strong inhibitors, or specific CYP2D6 substrates within 28 days prior to randomization.
- •Participants who have received chemotherapy within 4 weeks prior to surgery;
- •Use of other medications that may affect antiemetic efficacy as determined by the investigator, with the last use occurring less than 5 half-lives before the start of investigational product administration (based on the actual drug label; if the half-life is unknown, a 48-hour washout period should be applied).
- •Participants scheduled to receive anesthetic methods not specified in the protocol, including local anesthesia, regional anesthesia [e.g., nerve block, neuraxial block (including subarachnoid block, epidural anesthesia, or combined spinal-epidural anesthesia)], and total intravenous anesthesia;
- •Participants expected to require an in-place nasogastric tube or orogastric tube after surgery completion;
- •Participants expected to be transferred to the ICU for sedation with endotracheal intubation after surgery or those unable to undergo nausea and vomiting record assessments;
- •Participation in another clinical study of a drug or device within 3 months prior to screening (having signed informed consent and received investigational product/device treatment);
- •Daily excessive consumption of tea, coffee, grapefruit/grapefruit juice, pomelo juice, or caffeinated beverages (average > 8 cups per day, 200 mL per cup) within 14 days prior to randomization;
- •Any other condition that, in the investigator's opinion, makes the participant unsuitable for participation in this trial.
