Factors influencing the long-term maintenance of spasticity neurotoxin treatment.
(PubMed, J Neurol Sci)
- "Results suggest spasticity patients are likely to continue treatment if they are properly educated on BoNT therapy, experience improvement in spasms and mobility, and have a strong physician-patient relationship. These findings highlight the importance of effective physician-patient relationships and proper education on BoNT therapy."

Hypersensitivity Reactions Associated With Aesthetic Botulinum Toxin A Injections: A Case Series.
(PubMed, Cureus)
- "In the first case, a 44-year-old woman developed severe angioedema after resuming abobotulinumtoxinA injections following a 12-month pause. Subsequent intradermal tests with onabotulinumtoxinA and incobotulinumtoxinA produced localized reactions, suggesting hypersensitivity to a shared component across formulations, possibly the 150 kDa BoNT/A neurotoxin itself. In the second case, a 38-year-old woman experienced delayed erythema and swelling after letibotulinumtoxinA treatment but tolerated subsequent incobotulinumtoxinA injections, suggesting possible reactivity to complexing proteins or other non-core components rather than the neurotoxin. In the third case, a 50-year-old woman developed systemic symptoms and localized swelling after prabotulinumtoxinA administration, consistent with a delayed-type hypersensitivity reaction...Overall, this case series underscores the importance of clinical vigilance, appropriate patient selection, and awareness of rare but meaningful..."

Computational Model-Informed Comparative Evaluation of Botulinum Toxin A Formulations: A 20-Year Simulation of Onset, Diffusion, Duration, and Immunogenicity.
(PubMed, Toxicon)
- "LetibotulinumtoxinA and PrabotulinumtoxinA predicted the most balanced profiles, combining high efficacy (mean peak strain reduction 72% and 68%, respectively), rapid onset (2.7-3.1 days), and minimal predicted neutralizing antibody incidence over 20 years (0.4-0.6%). DaxibotulinumtoxinA showed the longest modelled duration of effect (median 142 days), whereas AbobotulinumtoxinA and Relatox exhibited broader diffusion and higher immunogenicity risk...These simulations align closely with available empirical data and suggest that formulation-specific differences in protein structure, diffusion behaviour, and antigenicity may contribute to observed clinical variability. Model-informed comparative analysis can complement real-world and prospective studies to optimize product selection and dosing strategies in aesthetic and therapeutic applications."

LIFE-THREATENING GENERALIZED MUSCLE WEAKNESS DEVELOPING AFTER INTRAVESICAL BOTULINUM TOXIN APPLICATION IN A CASE WITH NEUROGENIC BLADDER
(ESPN 2025)
- " Case: A 6-year-old girl who underwent surgery for meningomyocele, was on tolterodine for neurogenic bladder, and had a clean intermittent catheter, and showed bilateral grade 5 vesicoureteral reflux (VUR) taken for recurrent urinary tract infection. Subureteric transurethral injection (STING) and intravesical 30 units/kilogram abobotulinumtoxinA were applied... BTX prevents the fusion of neurosecretory vesicles at presynaptic nerve endings and the release of acetylcholine. It can be applied cystoscopically to the detrusor muscles to reduce intravesical pressure in the storage or to the sphincters to facilitate voiding in detrusorsphincter dyssynergia. Side effects occur when the toxin passes into the bloodstream and affects neuromuscular junctions in separate regions or through retrograde axonal transport to spinal motor neurons."

Budget Impact Analysis of Botulinum Toxin Type A for Patients with Severe Blepharospasm in Thailand.
(PubMed, Clinicoecon Outcomes Res)
- "This study aimed to assess the budget impact of introducing BoNT-A treatment (Onabotulinumtoxin A and Abobotulinumtoxin A) compared with current oral medications for severe blepharospasm in Thailand. Without dose sharing, the NBI rose significantly, reaching 40.5 million THB (1.14 million USD) for abobotulinumtoxin A. BoNT-A treatment increases healthcare costs, primarily due to drug costs. However, reduced injury costs and dose-sharing strategies may enhance affordability and support BoNT-A's inclusion in Thailand's National List of Essential Medicine."

Use of Botulinum Toxin Application in the Inferior Oblique Capitis Muscle Under Tomographic Guidance in Cervical Dystonia Report of Two Cases
(MDS Congress 2025)
- "Background: The first case involves a 23-year-old patient with a psychiatric condition and a history of receiving risperidone...150 units of "Dysport" were applied to this muscle under tomographic guidance (Siemens brand, 64 slices), with local anesthesia (2% lidocaine) using a Spinocath. The analysis of cervical dystonia cases using the Col/Cap concept and the subsequent application of botulinum toxin to frequently involved deep muscles using tomographic guidance results in a significant improvement in treatment outcomes."

BOTULINUM TOXIN IN PAIN RELATED POST STROKE UPPER LIMB SPASTICITY: A META-ANALYSIS ON EARLY AND LATE INJECTIONS
(WCN 2025)
- "The search included studies from January 2000 until January 2024. Twelve RCTs were analyzed wherein 8 used abobotulinumtoxinA, 2 used onabotulinumtoxinA, 1 used Neu-BoNT/A and 1 used incobotulinumtoxinA. Based on the pooled data from the multiple studies, there is no significant difference in the scores measuring pPSS between patients who received early BoNT injections and those who received placebo. Based on the pooled data from the multiple studies, there is no significant difference in the scores measuring pPSS between patients who received early BoNT injections and those who received placebo. This finding suggests that within the early treatment period, BoNT may not be more effective than a placebo in reducing pPSS. However, it is important to note that the data for early BoNT injections is still limited indicating that more research is needed to draw definitive conclusions [z= 1.08 (p= 0.28)]."

Evaluation of the diffusion characteristics of LetibotulinumtoxinA in comparison to Ona- and AbobotulinumtoxinA in a double-blind, randomized split-face study
(EADV 2025)
- "Therefore, the diffusion characteristics of LetibotulinumtoxinA (Leti-BoNTA), the market leader in South Korea, was compared with OnabotulinumtoxinA (Ona-BoNTA) and AbobotulinumtoxinA (Abo-BoNTA) in a randomized, double-blind, intra- individual split-face comparison. Leti-BoNTA exhibits precise and predictable diffusion while achieving the same clinical efficacy as Ona- and Abo- BoNTA4. Due to the significant differences in diffusion characteristics, treatment protocols should take product- specific behaviour into account, especially when changing formulations. Selection of the appropriate formulation is critical, as diffusion properties can influence therapeutic outcomes."

- "V1 – Screening; V2 – Start: BTX-A (Dysport) injected; creams/serum applied daily. The formulation containing Subderma-Complex™ and neuromuscular modulating peptides is safe and is capable of sustaining the Botox effect. A limitation of the study is the absence of a control arm testing the formulation without the proprietary complex, which prevents isolation of the complex's specific contribution to the observed effect."

A Pilot Study of Differences in Antibody Responses of Intradermal and Intramuscular Injections of Botulinum Toxin Type A.
(PubMed, Dermatol Ther (Heidelb))
- "Intradermal injection of BoNT/A appears to elicit a stronger immunogenic response than intramuscular administration, although antibody levels did not reach clinically significant thresholds. These findings underscore the importance of injection technique and interval planning to mitigate immunogenicity. Given the widespread use of intradermal techniques in aesthetic practice, this study provides important clinical insight into optimizing BoNT/A administration."

In Silico Multiscale Computational Modelling of Botulinum toxin A Diffusion for Glabellar Wrinkle Treatment: Optimizing Injection Volumes across formulations.
(PubMed, Toxicon)
- "Simulations encompassed five formulations- AbobotulinumtoxinA (ABO), DaxibotulinumtoxinA (DAXI), IncobotulinumtoxinA (INCO), OnabotulinumtoxinA (ONA), and PrabotulinumtoxinA (PRABO)-across injection volumes from 0.025 to 0.1 mL, at fixed toxin unit dosing, within anatomically realistic glabellar meshes (n=10,000 synthetic patient variants)...This study provides the first in-silico quantitative, multiscale evidence that reducing BoNT/A reconstitution volume to ≤0.045 mL/site significantly enhances target localization while minimizing off-target effects. Contrary to prevailing clinical heuristics, dilution amplifies mechanical spread and immune clearance risk."
