Detailed Description
In this research, characterized as a randomized, double-blind, parallel study, 200 healthy volunteered patients aging 18 or older will be distributed into 4 groups (n=50) as follows: Group I – 500mg Erythrina mulungu; Group II – placebo; Group III ; 100 mg Passiflora incarnata; Group IV – 15 mg midazolam. All treatments will be administered p.o. 1 hour randomly prior to the surgical procedures. The level of anxiety will be assessed through questionnaires and physical parameters, such as blood pressure, heart rate and oxygen concentration in three periods: at baseline, right before the surgical procedures and after 7 days. Data will be collected, tabulated and analyzed by the following statistical tests: chi-square, t-test, ANOVA and Tukey test, Friedman, Fisher's exact test with significance level of 5%.
Interventions
- Drug: Mulungu
- 500 mg/single dose/1 hour before dental surgery
- Drug: Placebo
- 500 mg/single dose/1 hour before dental surgery
- Drug: Passiflora incarnata
- 100 mg/single dose/1 hour before dental surgery
- Drug: midazolam
- 15 mg/single dose/1 hour before dental surgery
Arms, Groups and Cohorts
- Active Comparator: Mulungu
- 500 mg Mulungu Matusa® (Erytrina mulungu, 2 capsules of 250 mg) to be administered v.o., one hour before the surgical procedure.
- Placebo Comparator: placebo
- 500 mg of starch (2 capsules of 250 mg) to be administered v.o., one hour before the surgical procedure.
- Active Comparator: Passiflora incarnata
- 100 mg Passiflora incarnata (2 capsules of 50 mg) to be administered v.o., one hour before the surgical procedure.
- Active Comparator: midazolam
- 15 mg midazolam (2 capsules of 7.5 mg) to be administered v.o., one hour before the surgical procedure.
Clinical Trial Outcome Measures
Primary Measures
- Changes in anxiety report
- Time Frame: Change from baseline to 7 days
- Changes in the subjects’ anxiety level will be observed by using a Modified Corah Dental Anxiety Scale in three times: at baseline, in the day of surgery and after 7 days of the procedure.
Secondary Measures
- Changes in blood pressure
- Time Frame: Change from baseline to 2 hours
- blood pressure (mmHg) will be measured before the drugs administration, 30 minutes after drugs administration and during local anesthesia, incision, tooth removal and suturing.
- Changes in heart rate
- Time Frame: Change from baseline to 2 hours
- heart rate (bpm) will be measured before drugs administration, 30 minutes after drugs administration and during local anesthesia, incision, tooth removal and suturing.
- Changes in oxygen saturation
- Time Frame: Change from baseline to 2 hours
- oxygen saturation (SpO2) will be measured before drugs administration, 30 minutes after drugs administration and during local anesthesia, incision, tooth removal and suturing.
