2. Scheduled to remove the impacted tooth.
3. Any NRS score ≥5 within 4 hours after the surgery.
4. Willing to comply with the study procedures and requirements.
5. Willing and able to provide written informed consent for this study.

Exclusion Criteria:

1. Subjects who had used other drugs that affect the analgesic effect.
2. Subjects who have infection or other complications on the planned oral surgical site.
3. Subjects with uncontrolled hypertension or hypotension.
4. Subjects with severe cardiovascular and cerebrovascular diseases.
5. Subjects with severe gastrointestinal disease.
6. Subjects with a history of drug or alcohol abuse.
7. Subjects with significant abnormal electrocardiogram.
8. Subjects with significant abnormal laboratory value.
9. Subject who were allergic to the study drug and ingredients.
10. Pregnancy, lactation or having recent pregnant plan.
11. Subjects who participated in other clinical research study 30 days before entering this study.
12. Other conditions unsuitable for participation in the study.

Primary outcomes:
measure: the Sum of Pain Intensity Differences (SPID) using numerical rating scale (NRS, ranging from 0-10, the larger the number, the more severe the pain) 0-8 hours after drug administration
timeFrame: 0-8 hours after drug administration
Secondary outcomes:
measure: the Differences of Pain Intensity (PID) form each evaluating timepoint to baseline using numerical rating scale (NRS, ranging from 0-10, the larger the number, the more severe the pain) after drug administration
timeFrame: 0-12 hours after drug administration
measure: the Sum of Pain Intensity Differences (SPID) using numerical rating scale (NRS, ranging from 0-10, the larger the number, the more severe the pain) 0-4 hours after drug administration
timeFrame: 0-4 hours after drug administration
measure: the Sum of Pain Intensity Differences (SPID) using numerical rating scale (NRS, ranging from 0-10, the larger the number, the more severe the pain) 0-12 hours after drug administrationadministration
timeFrame: 0-12 hours after drug administration
measure: Pain relief degree at each evaluating timepoint using pain relief scale (PAR, ranging from 0-4, the larger the number, the more obvious the pain relief) after drug administration
timeFrame: 0-12 hours after drug administration
measure: Sum of pain relief degree within 4 hours using pain relief scale (PAR, ranging from 0-4, the larger the number, the more obvious the pain relief) after drug administration (SPAR)
timeFrame: 0-4 hours after drug administration
measure: Sum of pain relief degree within 8 hours using pain relief scale (PAR, ranging from 0-4, the larger the number, the more obvious the pain relief) after drug administration (SPAR)
timeFrame: 0-8 hours after drug administration
measure: Sum of pain relief degree within 12 hours using pain relief scale (PAR, ranging from 0-4, the larger the number, the more obvious the pain relief) after drug administration (SPAR)
timeFrame: 0-12 hours after drug administration
measure: Proportion of subjects who reaches a 50% reduction in pain intensity from baseline using numerical rating scale (NRS, ranging from 0-10, the larger the number, the more severe the pain) at each evaluating timepoint
timeFrame: 0-12 hours after drug administration
measure: Time from drug administration to the first NRS score≤3
timeFrame: 0-12 hours after drug administration
measure: Time from drug administration to the first use of rescue medication
timeFrame: 0-12 hours after drug administration
measure: Proportion of subjects who receive rescue therapy during the treatment period
timeFrame: 0-12 hours after drug administration
measure: Subject's overall satisfaction score of the study medication using subject satisfaction scale (ranging from 0-10, the larger the number, the higher the satisfaction)
timeFrame: 12 hours after drug administration
