Abstract:
Introduction: Botulinum toxin type A (BTA) is widely known for its applications in
aesthetic medicine, such as in the treatment of facial wrinkles. However, its therapeutic
use has expanded significantly, covering several areas of the health field due to its
neuromuscular blocking properties. This expansion justifies the need for a detailed
review of recent literature to map these new clinical applications. Objective: This study
aimed to review the scientific production on botulinum toxin type A, published between
2019 and 2023, to identify its various therapeutic applications beyond the aesthetic
field. Methodology: A bibliographic review was carried out in the SciELO and
Biblioteca Virtual em Saúde (BVS) databases. 33 scientific articles were identified, of
which 10 were discarded due to failure to meet the established filter criteria, such as
articles written in another language, applications on animals or duplicity, resulting in
23 articles analyzed. Results and Discussion: The results revealed a wide field of
applications for botulinum toxin type A. In addition to aesthetic indications, neurological
treatments stood out, such as dystonia and spasticity, as well as applications in
gastroenterology and the treatment of chronic pain, such as headaches and migraines.
These results highlight the versatility of botulinum toxin type A and its growing
importance in various medical specialties. Final Considerations: The review
demonstrates that botulinum toxin type A is a valuable therapeutic tool in multiple
health fields. The expansion of its therapeutic indications highlights the need for
continued research to explore and optimize its use in a variety of medical treatments.
