lamotrigine monotherapy better than carbamazepine in Poststroke Epilepsy: JAMA

The Results of the study are:

A total of 2577 patients (1400 men [54%]; median age, 78 years [IQR, 69-85 years]) were included. The adjusted hazard ratio of all-cause death compared with carbamazepine was 0.72 (95% CI, 0.60-0.86) for lamotrigine, 0.96 (95% CI, 0.80-1.15) for levetiracetam, 1.40 (95% CI, 1.23-1.59) for valproic acid, 1.16 (95% CI, 0.88-1.51) for phenytoin, and 1.16 (95% CI, 0.81-1.66) for oxcarbazepine. The adjusted hazard ratio of cardiovascular death compared with carbamazepine was 0.76 (95% CI, 0.61-0.95) for lamotrigine, 0.77 (95% CI, 0.60-0.99) for levetiracetam, 1.40 (95% CI, 1.19-1.64) for valproic acid, 1.02 (95% CI, 0.71-1.47) for phenytoin, and 0.71 (95% CI, 0.42-1.18) for oxcarbazepine.

Thus, the researchers concluded that the cohort study's findings suggest differences in survival between patients treated with different ASMs for poststroke epilepsy. Patients receiving lamotrigine monotherapy had significantly lower mortality compared with those receiving carbamazepine. The opposite applied to patients prescribed valproic acid, who had a higher risk of cardiovascular and all-cause death. Levetiracetam was associated with a reduced risk of cardiovascular death compared with carbamazepine, but there was no significant difference in overall mortality.
