| Scientific title | Comparative randomised cross-over study of the efficacy and safety of the extract of the roots of the South-African Uzara plant and ibuprofen in the treatment of patients with primary dysmenorrhoea |
| Study objectives | It is documented that the extract of the roots of the South-African Uzara plant (Uzara®) has an inhibitory action on the motility of smooth muscle organs through stimulation of the inhibitory sympathetic supply. This characteristic action is proved to affect the circular and longitudinal muscle of the whole intestinal tract, the urinary bladder, and the uterus. Hence, the use of Uzara® would inhbit painful uterine contraction and cramping pain in subjects with moderate to severe primary dysmenorrhoea. |
| Ethics approval(s) | Ethics and Research Committee of Faculty of Medicine, Ain Shams University, September 2010. |
| Health condition(s) or problem(s) studied | Primary dysmenorrhoea |
| Intervention | The subjects will be recruited from female students attending clinical classes in medicine (Faculty of Medicine) or nursing (High Institute of Nursery) at Ain Shams University Maternity Hospital. Sixty students having moderate or severe primary dysmenorrhoea and adhering to inclusion criteria will be recruited and a written consent will then be obtained before admission into the study. Pre-treatment ultrasound screening will be performed to exclude any pelvic pathology. The case record form will be filled, including demographic information such as patient's age, parity, medical and surgical histories, and indications for the surgery. Then, historical data will be collected including measurement of severity of dysmenorrhoea, pain assessment by pain scales: visual analogue scale (VAS), self-reported and self-rated verbal scale, and multidimensional scoring system (MDS). Visual Analogue Scale (VAS) is a one-dimensional linear scale of 0 - 10 cm (0 cm representing no pain; 10 cm, severe pain) with values greater than 5 defined as moderate or severe. The Verbal Scale is a 4-point verbal score (on a categorical of: 0, none; 1, mild; 2, moderate; and 3, severe menstrual pain). Multidimensional scoring system defines the severity of dysmenorrhoea as mild, moderate and severe based on pain, limited activities and medication taken. The presence of other associated symptoms (including headache, dizziness, mood changes [nervousness], stomach cramps, nausea or vomiting, diarrhoea, constipation, oedema, and weakness) will be subjectively scored (no, mild, moderate, and severe) and recorded. Females with moderate or severe primary dysmenorrhoea will be invited to participate in the study. Following consent, participants will be randomised to one of the following interventional trial arms: 1. Study drug: the extract of the roots of the South-African Uzara plant (Uzara® 40 mg coated tablets). This will be taken for five days (maximum), orally 2 tablets/8 hours for two doses then 1 tablet/8 hours. If there is mild or no pain 8 hours from the last dose, the use of drug should be stopped. 2. Control drug: ibuprofen 400 mg sugar coated tablets (Brufen®). This will be taken for five days (maximum) orally 1 tablet/6 hours. If there is mild or no pain 6 hours from the last dose, the use of drug should be stopped. The interval between two successive menses will suffice as a wash-out period. The drug will be started at the onset of menstruation or when pain is felt to be impending, in the routine stated above. The participants will record the pain intensity they experienced right before taking intake of the medication (0 hour) and after 4, 12, 24, 48 - 60 and 96 - 120 hours. For assessing the pain, both the VAS and Verbal Scale will be recorded at these 6 timepoints, as well as the multidimensional scoring system. The use of other analgesics is to be allowed for those receiving little or no relief of severe pain. This will be permitted 1 hour or more after the intake of the test drug and in such cases the last value of pain intensity/relief scores will be carried forward and used for the analysis. On using this rescue or backup medication, the type, dose, frequency of administration and the response will be recorded. The presence of other associated symptoms will be subjectively scored (no, mild, moderate, and severe) and recorded. Data entailing possible adverse events to the drug will be collected. Tolerability will be assessed by recording adverse reactions during drug intake. At the termination of the 2 cycle study period, the patients will be asked to rank the preparations in order of effectiveness. |
