Pharmacokinetic Effect of Y-3 on Repaglinide，Warfarin and Omeprazole in Healthy Participants

The primary goal of this clinical trial is to evaluate the effect of Y-3 for injection on the pharmacokinetic profile of the sensitive finger substrates repaglinide tablets, warfarin sodium tablets, and omeprazole enteric-coated capsules for CYP2C8, CYP2C9, and CYP2C19 in Chinese healthy participants, to evaluate whether Y-3 for injection(40mg) will have clinical drug interactions with repaglinide tablets, warfarin sodium tablets and omeprazole enteric-coated capsules, so as to provide a reference for the drafting of Y-3 drug instructions for injection and a basis for the safe and rational use of the drug after marketing. The secondary goal of this clinical trial is to observe the effect of Y-3 for injection on the safety of repaglinide tablets, warfarin sodium tablets and omeprazole enteric-coated capsules. The main questions it aims to answer are: What the pharmacokinetic profiles of repaglinide tablets, warfarin sodium tablets, and omeprazole enteric-coated capsules when using Y-3 (40 mg) in healthy participants. If Y-3 for injection (40mg) will have clinical drug interactions with repaglinide tablets, warfarin sodium tablets and omeprazole enteric-coated capsules If Y-3 for injection (40mg) is safe in participants who using repaglinide tablets, warfarin sodium tablets, and omeprazole enteric-coated capsules. Researchers will see what the pharmacokinetic profiles and safety of repaglinide tablets, warfarin sodium tablets, and omeprazole enteric-coated capsules when using Y-3 (40 mg) in healthy participants. Participants will: Take repaglinide tablets, warfarin sodium tablets and omeprazole enteric-coated capsules without Y-3. Take repaglinide tablets, warfarin sodium tablets and omeprazole enteric-coated capsules during the use of Y-3. Answer questions regarding your medical history.
