Efficacy of Gemfibrozil as an Adjunct to Sertraline in Major Depressive Disorder, A Double-Blind, Randomized, and Placebo-Controlled Clinical Trial

Objective: Major depressive disorder (MDD) is predicted to be one of the biggest disease burden in the future. The antidepressant activity of gemfibrozil has been recently considered. In this study, we assessed the effectiveness of gemfibrozil as a sertraline adjunct in treating patients with MDD.

Method: In this study, 46 patients with MDD based on the DSM-V criteria with a minimum score of 22 on the 17-item Hamilton Rating Scale for Depression (HAM-D) were divided into two groups. One group was treated with 300 mg of gemfibrozil daily and the other group treated with placebo. Each group was treated simultaneously with 100 mg of sertraline daily for 8 weeks. The trial was randomized and double-blind. To assess the response to treatment, patients were evaluated at baseline and then at weeks 2, 4 and 8 using the HAM-D score.

Results: The study was completed by 45 patients up to the final stages and follow-up visits. Repeated measure ANOVA with a Greenhouse-Geisser correction showed a significant difference for time×treatment interaction on within-subjects HAM-D scores [p–value= 0.026]. A notable difference was seen in time [p–value < 0.001]. The test of between-subject effects also represented a remarkable consequence of treatment on HAM-D scores at weeks 2, 4, and 8 [p–value = 0.07]. Using Kaplan-Meier estimate curves, time to remission periods were notable different between the 2 trial groups [Log-Rank p–value = 0.003].

Conclusion: Gemfibrozil is an effective adjunctive treatment in MDD and can be used to reduce depression symptoms.

A meta-analysis: efficacy and safety of anti-epileptic drugs prescribed in Korea as monotherapy and adjunctive treatment for patients with focal epilepsy

Focal epilepsy is the most common type of epilepsy in Korea, and anti-epileptic drugs (AEDs) are the main treatment option for patients. This study aimed to compare the efficacy and safety of AEDs for focal epilepsy through a meta-analysis. The AEDs prescribed in Korea as monotherapy and adjunctive treatment for patients with focal epilepsy were included for analysis. Relevant articles were searched for randomized clinical trials of AEDs and treatment outcomes were analyzed on the basis of the 50% responder rate, seizure-free rate, treatment withdrawal rate, and emergence rates of adverse events (AEs). The odds ratios (ORs) and their 95% confidence intervals (CI) of study outcome were calculated using combined data from multiple studies. A total of 47 studies were included in the meta-analysis. The seizure-free rate, treatment withdrawal rate, and AE rate were not significantly different among the AEDs recommended for monotherapy. Among the AEDs recommended for adjunctive treatment, topiramate and oxcarbazepine yielded the highest OR in comparison with placebo for each efficacy parameter: the 50% responder rate for topiramate = 6.42 (3.76–11.6) and the seizure-free rate for oxcarbazepine = 32.7 (6.05–899). The third-generation AEDs (brivaracetam and perampanel) yielded relatively better safety outcomes than other AEDs. In general, the 50% responder rate and treatment withdrawal rate tended to increase as the dose of the AEDs increased. The results from the current meta-analysis of the efficacy and safety data of various AEDs may provide insight into optimal pharmacotherapy for the treatment of focal epilepsy.
