Multicenter Study Comparative Study Clinical Trial
A comparison of the efficacy and tolerability of controlled-release carbamazepine with conventional carbamazepine.
We compared the efficacy and tolerability of controlled-release carbamazepine (CBZ-CR) with conventional carbamazepine (CBZ) in 131 epileptic patients (both men and women, ages 6-65 years) in an open, multicentre, cross-over trial. Patients entered into the trial were previously on CBZ monotherapy or polytherapy. ⋯ In 44/131 (34%) of patients, the switch to CBZ-CR was accompanied by an improvement in tolerability, primarily due to a reduction in peak-dependent CNS side-effects such as tiredness, double or blurred vision, dizziness and ataxia. At the end of the study, investigators preferred CBZ-CR for 76% of their patients and 70% of the patients preferred CBZ-CR.
