ClinConnect Summary

This clinical trial is studying the effectiveness and safety of a medication called Ranquilon in treating anxiety disorders related to neurasthenia (a condition marked by fatigue and irritability) and adaptation disorders (stress-related issues). Participants in the study will take Ranquilon at a daily dose of 6 mg and compare its effects to another medication called Afobazole, which will be given at a dose of 30 mg per day. The trial is currently looking for adults aged 18 to 70 who have been diagnosed with anxiety based on specific medical guidelines.

To be eligible for this study, participants need to have moderate anxiety levels and meet several health criteria. For instance, they should not have certain serious health conditions, such as severe depression or substance abuse issues, and women must have a negative pregnancy test. Participants can expect to take the assigned medication regularly and attend follow-up visits for assessments during the trial. It’s important to know that anyone can choose to withdraw from the study at any time, and this will not affect their future medical care.
