About this trial
The goal of this clinical trial is to learn if medroxyprogesterone acetate oral suspension (Meishiya®) works to prevent nausea and vomiting caused by single-day moderate to high emetogenic chemotherapy (MEC/HEC) in the whole-process management. It will also learn about the safety of medroxyprogesterone acetate oral suspension (Meishiya®). The main questions it aims to answer are:
Does medroxyprogesterone acetate oral suspension (Meishiya®) effectively prevent nausea and vomiting induced by single-day MEC/HEC in the whole-process management? What medical problems do participants have when taking medroxyprogesterone acetate oral suspension (Meishiya®)? Researchers will adopt a multicenter, randomized controlled, open-label trial design and compare the effects of medroxyprogesterone acetate oral suspension (Meishiya®) in preventing chemotherapy-induced nausea and vomiting.
Participants will be:
Stratified based on chemotherapy regimens (HEC vs MEC), gender (male vs female), and age (\<55 years vs ≥55 years) Planned to be 126 subjects who are first-time recipients of single-day MEC/HEC for malignant solid tumors Take medroxyprogesterone acetate oral suspension (Meishiya®) as per the study protocol during the chemotherapy period Visit the research centers at specified intervals for checkups and assessments Record details of nausea, vomiting episodes, and any adverse reactions in a diary
Eligibility criteria
Qualifiers

Planning to receive other moderate to high emetogenic chemotherapy drugs within days 2 to 8 after the first day of chemotherapy;
Planning to receive chemotherapy regimens including conventional paclitaxel (using castor oil as solvent);
Having taken drugs with potential antiemetic effects within 2 days before enrollment: 5-HT3 receptor antagonists (e.g., ondansetron, etc.), phenothiazines (e.g., prochlorperazine), butyrophenones (e.g., haloperidol), benzamides (e.g., metoclopramide), domperidone, cannabinoids, traditional Chinese medicines with potential antiemetic effects, scopolamine, cyclizine, etc.;
