Possible pharmaceutical treatment?

Possible pharmaceutical treatment? I saw a study on the stuttering foundation website about a 57 year old doctor who took alprazolam (1.0 mg twice daily) and citalopram (10 mg at bedtime). This was in 2000, so 25 years ago, but they treated 3 other patients and they went from a 6-7 in severity to 1-2.
