Preliminary pharmacologic evidence suggests that tiagabine, a new presynaptic gamma-aminobutyric acid-uptake inhibitor developed as an antiepileptic drug, may also relieve spasticity. This pilot study assessed the drug's efficacy in 14 children with congenital or acquired spastic quadriplegia and concomitant intractable epilepsy refractory to treatment with multiple antiepileptic drugs. The primary outcome variable was change in motor function; the secondary outcome was change in seizure frequency. Tiagabine was initiated at 0.1-0.2 mg/kg/day and then gradually titrated upward until seizures ceased, adverse effects supervened, or the maximum dose of 1.1 mg/kg/day was reached. When a modified Ashworth scale was used to assess motor function, a mean improvement of approximately 50% was observed. Common findings included improved tone, strength, coordination, range of motion, and relaxation of extremities, with less ataxia and wobbling. Mean reduction in seizure frequency was 50-74%. Randomized, double-blind controlled studies are needed to confirm the suggested efficacy of tiagabine in relieving chronic spasticity in children with neurodevelopmental disorders.

Tiagabine, developed as an anti-epileptic medication, has the potential to reduce spasticity. The purpose of the present study was to assess the effectiveness of tiagabine in decreasing spasticity and improving the functional abilities of children with spastic cerebral palsy (CP). Nine children (seven females, two males) with CP (six spastic quadriplegia, three moderate to severe spastic diplegia) were treated with tiagabine for a mean of 7.2 months. Median age was 4y 5mo (range 3y 2mo-10y). All children were non-ambulatory. According to the Gross Motor Function Classification System, six were Level IV and three were Level V. Only one child showed a median decrease >or=1.0 grade on the modified Ashworth scale in upper extremities, lower extremities, and overall. Another child had significant improvement in the Pediatric Evaluation of Disability Inventory Self-care score and improved feeding. None of the participants was found to have a significant improvement in motor function or a decrease in the number of motions (passive range of motion and muscle length test) that were limited. Reduction of nocturnal awakenings from painful spasms was reported in one child. Eight of the nine children experienced adverse side-effects during treatment. Although tiagabine was not found to be effective in decreasing children's spasticity or improving their function, its potential use in the relief of painful spasms associated with neurological conditions in the pediatric population warrants further investigation.
