Cotton flower is a Xinjiang Uygur ethnic medicine, and its main active ingredients are flavonoids. Studies have proved that flavonoids have strong characteristics of antioxidant stress and anti-inflammatory response. Preclinical pharmacodynamic studies on rats showed that the Flos Gossypii Flavonoids Tablet could significantly improve the learning and memory ability of AD model caused by different factors, and the mechanism may be related to its inhibition of oxidative stress and inflammatory response. A total of 57 subjects were enrolled in the Phase I tolerance clinical study. The results showed that the experimental drug may temporarily increase the three indexes of glutamic oxaloacetic transaminase, creatine kinase and lactate dehydrogenase, which can self-recovery in a short time. Combined with the safety evaluation results of phase I clinical trial, Flos Gossypii Flavonoids Tablet is a drug with high safety.
In clinical trials of preclinical pharmacodynamic studies, Flos Gossypii Flavonoids Tablet has been proved to significantly improve the learning and memory ability of Alzheimer's disease model. Phase I clinical tolerance test is to observe the human body's tolerance to Flos Gossypii Flavonoids Tablet, and provide a basis for the formulation of safe and reasonable dosing regimens for phase II clinical trials. Therefore, a Phase II clinical trial is now being conducted to explore the efficacy and safety of the Flos Gossypii Flavonoids Tablet in the treatment of mild to moderate Alzheimer's disease (marinus sea deficiency/brain collateral stasis syndrome). In this study, the researchers will use a multicenter, randomized, double-blind, placebo-controlled parallel method to recruit AD patients to confirm the efficacy and safety of Flos Gossypii Flavonoids Tablet. Confirmation of drug efficacy will be observed through changes in AD patients' general cognitive and different cognitive domain functions, daily living activities, and symptom severities.
