Inclusion Criteria: 1. Reviewed and signed the ICF. 2. Female between the ages of 18 and 35 (inclusive) at the time of signing the ICF. 3. Otherwise healthy female subjects with primary dysmenorrhea for at least 3 consecutive menstrual cycles prior to the study (prior to the start of the baseline cycles) and with VAS score >70 for the maximum dysmenorrheic pain or VAS score >40 for the average daily dysmenorrheic pain of the last menstrual cycle. 4. Recent (last 6 months) history of regular menstrual cycles. Regular menstrual cycle meant the period of the cycle fell in the range of 21 to 35 days. 5. No contraceptive injection, implant, or intrauterine device within 6 months prior to the study and willing not to use any of them during the entire study period. Subject agreed to the use of a highly effective method of contraception throughout the study including: - 28-day regimens of combined oral contraceptives, patches, or rings - Bilateral tubal sterilization - Partner vasectomy - Condoms and spermicide - Diaphragm and spermicide At the discretion of the investigator, total abstinence was permitted as a method where age, lifestyle, or sexual orientation of the subject ensured compliance. If the subject was taking combined hormonal contraception, it had to be taken for at least 6 months prior to screening and be used throughout the duration of the study without interruption. No more than 50% of enrolled subjects were to be taking combined hormonal contraception. 6. Agreed not to use any dietary supplement or alternative medication intended to treat dysmenorrhea and/or its accompanying symptoms during the entire study period. 7. Was able to tolerate ibuprofen and willing to use only ibuprofen supplied by the sponsor for this study as a rescue medication. 8. Was able to understand and follow the study instructions, to complete the electronic subject diary, and to communicate with the investigator and staff. Exclusion Criteria: 1. Known or suspected to have secondary dysmenorrhea due to pelvic inflammation, endometriosis, uterine myomata, ovarian pathological changes, or other pelvic diseases. 2. Known or suspected to have gastrointestinal or urological conditions that may cause abdominal/pelvic pain, such as colitis, appendicitis, irritable bowel syndrome, cholelithiasis, interstitial cystitis, urocystitis, nephrolithiasis, and other conditions that, according to the investigator's judgment, are not suitable for the study. 3. Use of an intrauterine contraceptive device, contraception injection, contraceptive implant, progesterone-only contraceptive pills, or an extended-cycle combined hormonal contraceptive regimen that does not foster cyclic withdrawal bleeding every 28 days within 6 months of screening or during the study. 4. Screening pelvic ultrasound findings suggestive of significant pathology including secondary causes of dysmenorrhea such as more than 2 uterine fibroids >3 cm in diameter, or complex ovarian cysts. At the discretion of the investigator, simple ovarian cysts <3 cm in diameter or functional ovarian cysts that were deemed to not require follow-up were permitted. 5. Obesity: body mass index (BMI) >32 kg/m2. 6. Positive gonorrhea and/or chlamydia test or evidence of other active sexually transmitted disease that, in the investigator's opinion, would make the subject not suitable for the study. 7. Known allergy to the study drug, or hypersensitivity to any of the study drug ingredients, or known allergy or intolerance to one or more of the excipients: ß cyclodextrin and lactose, and according to the investigator's judgment, the allergy/intolerance was so severe that the subject was not suitable for the study. 8. Presence of one or more than one of the following: cerebrovascular disease, cardiovascular disease, pulmonary embolism, coagulopathy, thrombophlebitis, optic neuritis, retinal vein thrombosis, liver tumor, kidney tumor, renal failure, hepatitis, or other serious primary diseases of hepatic, renal or hematopoietic systems and mental disorders that according to the investigator's judgment renders the subject unsuitable for the study; or any chronic disease(s) for which the subject had been taking long term medication, and according to the investigator's judgment was unsuitable for the study. The investigator may have contacted the medical monitor and/or sponsor with questions about whether a subject was suitable for the study. 9. Hypertension, defined as sitting blood pressure (BP) systolic >140 mm Hg or diastolic >90 mm Hg (repetition of the measurement of BP was permitted to confirm the subject's hypertension condition). 10. Pregnant or trying to conceive during the study. Recent delivery, abortion, or lactation within 3 menstrual cycles before the start of treatment. 11. Alcoholism or drug abuse within the last 6 months prior to the study. 12. Regular use of any concomitant medications that might have confounded efficacy and/or safety assessments including, but not limited to, the following: narcotic, non NSAID, or NSAID analgesics for the treatment of conditions other than dysmenorrhea, psychotropic drugs, antidepressants, sedative hypnotics, sedating antihistamines, muscle relaxants, or tranquilizers. Selective serotonin reuptake inhibitors and serotonin norepinephrine reuptake inhibitors were permitted for indications other than pain provided that the subject had been on a stable dose for at least 2 menstrual cycles before providing consent for this study and agreed to remain on a stable dose throughout the course of the study. 13. Simultaneous participation in another clinical study or use of any experimental drug or device, or being a subject in another clinical research program within 30 days prior to the screening visit. 14. Use of any dietary supplement or alternative medication intended to treat dysmenorrhea or its accompanying symptoms within 30 days prior to the screening visit. 15.

Primary | The Change From Baseline to the End of Treatment Period in Maximum Dysmenorrheic Pain VAS Score | VAS is represented by a straight line with extreme limits: from "no pain" and an associated image of a happy face at the left endpoint to "unbearable pain" and an associated image of an unhappy face at the right endpoint. The left endpoint is the minimum pain score of zero while the right endpoint is the maximum pain score of 100. The dysmenorrheic pain (lower abdominal cramping pain) that usually occurs just before and/or during menstruation was measured in this study using a The Visual Analogue Scale (VAS). Pain was assessed during 9 menstrual cycles from the beginning of the screening to the end of follow-up. |
