Efficacy of escitalopram for poststroke depression: a systematic review and meta-analysis

Depression is very common after stroke, causing multiple sequelae. We aimed to explore the efficacy of escitalopram for poststroke depression (PSD). PubMed, Embase, Scopus, Cochrane Central Register of Controlled Trials, Clinical trials. gov, Wan fang Data (Chinese), VIP (Chinese) and CNKI (Chinese) were retrieved from inception to May 2021. We recruited Randomized Controlled Trials (RCTs) which met the inclusion criteria in our study. The depression rating scores, the incidence of PSD, adverse events as well as functional outcomes were analyzed. 11 studies and 1374 participants were recruited in our work. The results were depicted: the reduction of depression rating scores was significant in the escitalopram groups and the standard mean difference (SMD) was - 1.25 (P < 0.001), 95% confidence interval (95% CI), - 1.82 to - 0.68; the risk ratio (RR) of the incidence of PSD was 0.52 (95% CI, 0.29 to 0.91; P = 0.007 < 0.05), which was significantly lower in the escitalopram groups; Escitalopram is safe for stroke patients; there was improvement of the motor function. However, in sensitivity analyses, the conclusions of the motor function and the incidence of drowsiness were altered. The study suggests that escitalopram has a potentially effective role compared with control groups and demonstrates escitalopram is safe. However, the results of the motor function and the incidence of drowsiness should be considered carefully and remain to be discussed in the future.

Automated summary

Escitalopram is effective in treating poststroke depression, leading to a significant reduction in depression rating scores and the incidence of PSD. It is safe for stroke patients and associated with improved motor function. However, results regarding motor function and drowsiness should be interpreted with caution and further discussed in the future.
