ITB Therapy with Lioresal® Intrathecal (baclofen injection) has been proven through clinical studies to demonstrate safety and efficacy of screening and during long-term therapy.
Two clinical studies have demonstrated that severe spasticity of spinal origin responds to long-term ITB Therapy.2,4 Long-term control of severe spasticity was achieved in most patients in the studies. Complications and side effects were reported in both studies. The most common device-related complications were catheter kinks, dislodgments, and disconnections. The most common drug-related side effects were drowsiness, dizziness, blurred vision, slurred speech, hypotension, depression, and seizures.
Long-term effectiveness in spasticity of cerebral origin has been demonstrated (median of 67 months) with ITB Therapy; adverse effects experienced in the study were usually managed by dose adjustments. The most commonly reported drug-related adverse effects were hypotonia (25%), somnolence (19%), seizures (13%), and headache (2%).5
A statistically significant improvement was demonstrated with ITB Therapy in muscle tone, function, and quality of life among stroke survivors. Adverse events in this study included accidental injury (11%), somnolence (10%), dizziness (10%), hypotonia (8%), headache (5%), constipation (5%), pain (5%), urinary tract infection (5%), and hypertonia (5%).6
Subjective reports from caregivers indicate a reduction in use of oral medication for spasticity,7 and improvements in comfort, function, and/or ease of care7,8 during ITB Therapy.
