Caffeine vs. ALA in BMS Treatment. (BMS: Burning Mouth Syndrome. ALA: Alpha-Lipoic Acid.)

Overview

The aim of this study was to evaluate the efficacy of caffeine and alpha-lipoic acid in the treatment of burning mouth syndrome by symptom assessment with visual analogue scale.

The etiology of BMS is multifactorial, involving a complex interplay of neuropathic, psychological, neuroendocrine, and immunological factors. Neurologically, BMS has been categorized into three subtypes: peripheral small fiber neuropathy, subclinical trigeminal neuropathy, and inhibitory dopaminergic deficiency. Neuroimaging and peripheral nerve studies have further implicated altered brain activation patterns and increased expression of specific receptors like TRPV1 and P2X3 in the pathogenesis of BMS. Hormonal imbalances, particularly in estrogen levels, have also been suggested to contribute to contribute to the condition. Caffeine, a xanthine alkaloid chemically known as 1,3,7-trimethylxanthine, is recognized for its diverse biological functions. As a central nervous system stimulant, its primary mechanism involves antagonizing adenosine receptors, thereby enhancing the release of neurotransmitters such as dopamine and norepinephrine, which are known to play roles in analgesic pathways. Caffeine is also noted for its neuroprotective properties and is theorized to reduce the risk of neurodegenerative diseases. It affects the central processing of pain and is involved in regulating circadian rhythms and sleep-wake cycles. Additionally, caffeine has mild anti-inflammatory properties. Its stimulatory effects may also improve mood and cognitive function.
