OBJECTIVE: To compare the efficacy and safety of pregabalin and carbamazepine in patients with central post-stroke pain (CPSP).
METHODS: Patients included in the study were randomly assigned to either flexible-dose pregabalin treatment group or carbamazepine treatment group. The primary efficacy variable was face visual analog scale (F-VAS), the second efficacy assessment was used to assess the effect of treatment on mental health by Hamilton anxiety scale (HAMA) and Hamilton depression scale (HAMD).
RESULTS: The mean baseline pain score F-VAS was 6.47 in the pregabalin group and 6.58 in carbamazepine treatment group. F-VAS was significantly lower in the pregabalin group (1.64) than (3.94) carbamazepine treatment group after treatment. Pregabalin was significantly superior to carbamazepine in endpoint assessments on the HAMA and HAMD after treatment. F-VAS and HAMD were showed efficacy as early as week 2 and maintained for whole duration of the study. The average pregabalin dose in the 12-week study was 214.6 (150-375) mg/day. The mean dose (range) of carbamazepine received by the patients was 275.0 (200-400) mg/day. Mild or moderate, typically transient, somnolence and dizziness were the most common adverse events (AES). The differences of the side effects between the two groups were not significant.
CONCLUSIONS: Pregabalin, but not carbamazepine, may be effective in improving F-VAS, HAMA and HAMD in patients with CPSP.
