Abstract

|
Purpose: Venlafaxine and duloxetine have been shown to be effective in the treatment of neuropathic pain disorders. However, knowledge about the efficacy of venlafaxine and duloxetine on burning mouth syndrome (BMS) is still insufficient. The purpose of this study was to investigate the efficacy of venlafaxine and duloxetine on refractory BMS patients.
Methods: Twelve refractory BMS patients who were prescribed venlafaxine or duloxetine were included in this study. These patients did not respond to previous administration of clonazepam, alpha-lipoic acid, gabapentin, and nortriptyline. All participants were the primary type of BMS patients who had no local and systemic factors related to the oral burning sensation. The intensities of oral symptoms following venlafaxine or duloxetine administration were compared with those before administration and at baseline.
Results: Venlafaxine and duloxetine were prescribed to four and nine patients, respectively. One patient was prescribed both medications in turn. Among them, only two patients showed improvement of oral symptoms without side effects. In the other ten patients, symptoms failed to improve. Six of them reported that the drug was ineffective, and four of them stopped taking the medications on their own due to intolerable side effects, such as insomnia, constipation, drowsiness, dizziness, and xerostomia.
Conclusions: Venlafaxine and duloxetine may only relieve oral symptoms in a minority of refractory BMS patients. Further large-scale studies are needed to determine the potential clinical factors that could predict the efficacy of venlafaxine and duloxetine.
