Expansion of therapeutic applications of botulinum toxin: Advances and perspectives

Botulinum toxin, commonly known as Botox, has evolved from a tool for treating botulism to a widely used therapeutic solution for a variety of neuromuscular and glandular conditions. This summary covers recent studies highlighting the effectiveness and versatility of botulinum toxin in different clinical contexts. According to Dressler (2012), the toxin can block neuromuscular junctions and autonomic innervation of exocrine glands and smooth muscles, being indicated for dystonia, spasticity, cerebral palsy, hyperhidrosis, hypersalivation, and bladder dysfunction, among others. Studies show that treatment can reduce symptoms by up to 70% and provide relief for periods ranging from three to six months. Webb (2018) explores the therapeutic potential of botulinum neurotoxins, emphasizing the engineering of toxin variants with modified properties to expand their applications. Serrera-Figallo et al. (2020) review the clinical use of the toxin in orofacial pathologies, demonstrating its effectiveness in conditions such as bruxism, facial paralysis, and neuropathic pain, with no significant adverse effects reported. Kumar et al. (2016) discuss the potency of the toxin and its use in reducing muscle and glandular hyperactivity, as well as its emerging analgesic properties. Rasetti-Escargueil and Popoff (2020) highlight the evolution of botulinum toxin applications from treating strabismus to a wide range of medical and aesthetic conditions, with innovations in toxin engineering expanding its therapeutic potential. These advances reflect the growing importance of botulinum toxin as a versatile and effective therapeutic tool.
