Bu çalışma, trigeminal nöropati (trigeminal neuropathy) kaynaklı yüz ağrısının yönetiminde, trigeminal sinir blokajında Guanfacine ve Lidocaine ilaçlarının birlikte kullanımının etkinliğini incelemektedir. Çalışmaya, süregelen yüz ağrısı belirgin düzeyde olan ve daha önce bu amaçla sinir blokajı yapılmamış hastalar katılabilmiştir. Çalışma Faz 2 aşamasında yürütülmüş ve tamamlanmıştır.
