OBJECTIVE: [corrected] To evaluate efficacy and safety of botulinum toxin type B (BTX-B) in treatment of movement disorders including blepharospasm, oromandibular dystonia, hemifacial spasm, tremor, tics, and hypersecretory disorders such as sialorrhea and hyperhidrosis.
METHODS: A retrospective study of BTX-B injections in treatment of 58 patients with various neurological disorders was performed. The mean follow-up time was 0.9 +/- 0.8 years. Results of the first and last treatment of patients with at least 3 injection sessions were compared.
RESULTS: The response of 58 patients to a total of 157 BTX-B treatment sessions was analyzed. Of the 157 treatment sessions, 120 sessions (76.4%) resulted in moderate or marked improvement while 17 sessions (10.8%) had no response. The clinical benefits after BTX-B treatment lasted an average of 14 weeks. Of the 41 patients with at least 3 injection sessions (mean 10 +/- 8.6), most patients needed increased dosage upon the last session compared to the first session. Nineteen patients (32.8%) with 27 sessions (17.2%) reported adverse effects with BTX-B treatment.
CONCLUSIONS: Though most patients require increased dosage to maintain effective response after repeated injections, BTX-B is an effective and safe treatment drug for a variety of movement disorders, as well as drooling and hyperhidrosis.
