Efficacy of a combination of troxerutin and cerebroprotein hydrolysate in acute cerebral infarction: Meta-analysis and systematic review

Objective

To evaluate the efficacy and safety of combining troxerutin and cerebroprotein hydrolysate (TCH) for treating acute cerebral infarction via a systematic review.

Methods

The computer-based search encompassed eight databases—PubMed, Cochrane Library, Embase, Web of Science, China Biomedical Literature Database, China National Knowledge Infrastructure, Wanfang Data, and China Science and Technology Journal Database—from their establishment until December 2023. Randomized controlled trials that assessed TCH for acute cerebral infarction were selected according to inclusion and exclusion criteria. The data extraction, data quality evaluation, and meta-analysis were performed using RevMan 5.4.1 software.

Results

The analysis incorporated 18 studies encompassing 1,957 cases. Compared with the control group, the TCH treatment group had superior outcomes in effective rates (risk ratio [RR] = 1.24, 95% confidence interval [CI; 1.18, 1.30], Z = 8.84, p < 0.05), neurological deficit scores (mean difference [MD] = −3.71, 95% CI [−4.32, −3.10], Z = 11.92, p < 0.05), activity of daily living scores (MD = 13.32, 95% CI [11.66, 14.98], Z = 15.75, p < 0.05), changes in low shear viscosity (MD = −1.82, 95% CI [−2.57, −1.06], Z = 4.73, p < 0.05), and plasma fibrinogen levels (MD = −0.43, 95% CI [−0.47, −0.39], Z = 20.01, p < 0.05). However, there was no significant difference in adverse reaction between the two groups (RR = 0.72, 95% CI [0.45, 1.14], Z = 1.39, p = 0.16). No severe adverse drug reactions were observed in either group.

Conclusion

Combined TCH is effective and safe for treating acute cerebral infarction.
