Wei Li Bai Capsule is composed of sodium ferulate tablets, L-rhamnose and chrysin. Sodium ferulate tablet is a domestically marketed drug, L-rhamnose is a marketed food additive, and chrysin is a dietary supplement. All of them have been widely used and their safety has been confirmed. In addition, since these three compounds all show good potential in the treatment of Alzheimer's disease, and play an important role in regulating metabolism, improving blood circulation and anti-inflammatory and antioxidant, this study will explore the synergistic effect of Wei Libai capsule in patients with mild and moderate Alzheimer's disease in 130 subjects.
In clinical trials of preclinical pharmacodynamic studies, Wei Li Bai capsules has been proved to significantly improve the learning and memory ability of Alzheimer's disease model. In this study, the researchers will use a multicenter, randomized, double-blind, placebo-controlled parallel method to recruit Alzheimer's disease patients to confirm the efficacy and safety of Wei Li Bai capsules. Confirmation of drug efficacy will be observed through changes in Alzheimer's disease patients' general cognitive function scores, scores of different cognitive domains, daily living activities, and symptom severities.
