Brief Summary

The investigator's group at the Mexican Institute of Social Security has worked for more than 20 years in the scientific research of the plant species Galphimia glauca Cav., which is used in Mexican Traditional Medicine for the treatment of mental disorders. With the obtained results it was possible the development of a phytopharmaceutical elaborated with the extract of this plant, which was standardized in its content of Galphimine-B (G-B). This new compound is a nor, seco-triterpene, which possesses selective effects on the central nervous system. Through electrophysiological neuronal unitary records it was identified that G-B acts on the ventral tegmental area (VTA), and exerts its effect on (N-methyl-D-aspartate) NMDA receptors in dopaminergic neurons. The new phytopharmaceutical, elaborated from a standardized extract (in its G-B content) of G. glauca, was subjected to a double blind and randomized clinical study that compared its efficacy and therapeutic tolerability with a similar drug formulated with lorazepam in patients with diagnosis of generalized anxiety disorder (GAD). In a total of 152 patients, it was evidenced that the phytomedicine administered orally (for 4 weeks) was able to significantly reduce anxiety, in a similar way as lorazepam did, but with better tolerability. Several patients who were treated with lorazepam had to leave the study because they had daytime sleepiness. In clinical practice, different benzodiazepines have specific indications. In the case of anxiety disorders, the drug of first choice is Alprazolam, this, because it manifests a more powerful anxiolytic effect with a lower degree of sedation and daytime sleepiness. Objective: The present project aims to compare the efficacy and therapeutic safety of an elaborated phytopharmaceutical with the standardized extract of Galphimia glauca with Alprazolam .

Outcome Measures

Primary Outcomes (1)

  • Therapeutic efficacy: improvement of the clinical condition higher than 90%. It will be measured by means of the Hamilton Rating Scale for Anxiety.

    It will be considered when the patient presents an improvement of the clinical condition higher than 90% on the scales of measurement (HAM-A). Hamilton Rating Scale for Anxiety (HAM-A) consisted of 14 items that assessed the severity of anxiety. Each item was scored using a 5-point scale (0=not present to 4=very severe). The HAM-A Total Score could have ranged from 0 to 56 and higher scores indicated a greater degree of symptom severity. Scores 14-21 indicate mild anxiety; scores 21-29 indicate moderate anxiety; scores over 29 indicate severe anxiety

    Up to 10 weeks

Secondary Outcomes (2)

  • Therapeutic Tolerability: Number of participants with treatment-related adverse events as assessed by CTCAE v4.0

    Up to 10 weeks

  • Clinical Global Impression of Improvement Scale (CGI-I). A 7 points scale that is used to evaluate how much the patient's illness has improved or worsened relative to a baseline state at the beginning of the intervention.

    Up to 10 weeks

Study Arms (2)

Galphimia glauca standardized extract

EXPERIMENTAL

Patients with a clinical diagnosis of GAD (with a score of 18 points or more on the Hamilton anxiety scale) that will be included in the experimental group and will be assigned the treatment consisting of hard gelatin capsules with a pharmaceutical formulation prepared with a standardized extract from G. glauca, which will be administered once a day.

Dietary Supplement: Galphimia glauca standardized extract

alprazolam 1mg

ACTIVE COMPARATOR

Patients with a clinical diagnosis of GAD (with a score of 18 points or more on the Hamilton anxiety scale) that will be included in the control group and will be assigned the treatment consisting of hard gelatin capsules with the drug Alprazolam (1 mg ), which will be administered once a day.

Drug: alprazolam 1mg

Interventions

Each patient will be administered with a capsule once a day (in the morning), for 10 weeks. A capsule contains the standardized extract of Galphimia glauca corresponding to 0.374 mg of Galphimine-B

Galphimia glauca standardized extract

Each patient will be administered once a day (in the morning) for 10 weeks. A capsule contains 1 mg Alprazolam
