Application of botulinum toxin to treat sialorrhea in amyotrophic lateral sclerosis patients: a literature review

ABSTRACT Amyotrophic lateral sclerosis is a progressive and fatal neurodegenerative disease characterized by the degeneration of motor neurons, which are the central nervous system cells that control voluntary muscle movements. The excessive salivation (sialorrhea) is present in approximately 50% of amyotrophic lateral sclerosis cases. Thus, some alternative therapeutic methods are sought, such as anticholinergic drugs and surgery. Recently the use of botulinum toxin applied at a midpoint of the salivary glands, often guided by ultrasound, have demonstrated positive results. The objective was to review the literature to demonstrate an alternative method to treatments of sialorrhea in patients with amyotrophic lateral sclerosis. In recent studies, the efficacy of botulinum toxin is confirmed, although new applications are required. Since the side effects are negligible, this is an alternative to treat amyotrophic lateral sclerosis, and other patients with diseases that present sialorrhea.
