Low-Dose Intrathecal Ziconotide for Spasticity From Primary Lateral Sclerosis: A Case Report.

ABSTRACT

Spasticity can be very debilitating and painful. We present a case of severe spasticity from primary lateral sclerosis refractory to intrathecal baclofen in doses up to 1100 µg/d. Baclofen was weaned down and switched to intrathecal ziconotide at 0.6 µg/d. The dose was then titrated up to 3 µg/d with excellent control of spasticity. This case suggests that low-dose intrathecal ziconotide should be considered in patients with lower extremity spasticity refractory to intrathecal baclofen.
