Full description

Major depressive disorder (MDD), a common affective mental disorder caused by a variety of reasons, is mainly clinically manifested as significant and persistent low mood, loss of interest, retardation of thinking, pessimism, lack of initiative, self-guilt, loss of appetite, sleep disorders, and paranoia, often accompanied by various systemic discomfort that is inconsistent with objective examinations, and in severe cases, suicidal thoughts and behaviors[1]. Although there has never been a name called "depression" in ancient literature of traditional Chinese medicine, it has been long recognized since it is similar to many diseases in Chinese medicine literature (such as "depression syndrome" and "lily disease"). Depression is a common mental disorder that affects about one fifth people in a certain period in their lives.

According to the data disclosed by the WHO, there are more than 350 million people suffering from depression in the world, with an increase of about 18% in the past decade. According to the prevalence report of China Mental Health Survey (CMHS) in 2019[2], for depressive disorders, the lifetime prevalence was 6.8% and the 12-month prevalence was 3.6% in China, among which, for depression, the lifetime prevalence was 3.4%, and the 12-month prevalence was 2.1%. With the acceleration of the pace of modern life, its prevalence is spreading. Moreover, the pandemic of COVID-19 resulted in a 27.6% increase in global cases of major depressive disorder[3]. It is estimated that by 2030, depressive disorders will surpass tumors and cardiovascular and cerebrovascular diseases to become the largest disease burden in the world[4]. For the time being, there are limited treatment measures for depressive disorders, and about 30%-40% of patients have developed to refractory depression due to insensitivity to existing monoamine antidepressants[5]. Monoamine antidepressants have shortcomings such as slow action, residual symptoms, more adverse reactions, and long-term medication, while novel fast-acting antidepressants also have the problems of drug addiction and neurotoxicity[6], so its treatment is facing a new dilemma.

Traditional Chinese medicine has been used for prevention and treatment of various depressive disorders for more than two thousand years, and it costs less and has achieved reliable clinical efficacy and caused less toxic side effects. Traditional Chinese medicine believes that emotional factors, such as anger, sorrow, sadness, and too much thinking, result in liver dysfunction, spleen dysfunction, mental dysfunction, and then multiple viscera dysfunction, and long-term liver depression generates pathogenic fire and fire burns body fluid to produce phlegm, thus forming the critical pathogenesis of depression, i.e., qi stagnation, phlegm condensation, and fire stagnation. The prescription of Jieyu Chufan Capsules, originated from the Classical Prescriptions of Zhang Zhongjing, is prepared by modifying the Pinellia and Magnolia Decoction and the Cape jasmine and Magnolia Decoction. Since 1997, modified Jieyu Chufan Capsules has been used to treat 12,000 outpatient cases, including 445 cases of depression and anxiety. The phase III clinical study of Jieyu Chufan Capsules[7] showed that Jieyu Chufan Capsules effectively improved depression and anxiety and effectively alleviated the physical symptoms of patients with mild to moderate depressive disorders, and the incidence of adverse reactions was comparable to that of placebo and significantly lower than that of fluoxetine.

The prescription of Jieyu Chufan Capsules, originated from the Classical Prescriptions and developed based on clinical application, has significant clinical efficacy in clearing heat and relieving fidgetiness, activating qi and eliminating phlegm. The randomized, double-blind, placebo-controlled, multicenter clinical study will be conducted to further evaluate the efficacy and safety of Jieyu Chufan Capsules in the treatment of symptoms related to moderate to severe depression in a wider population. The reliable evidence-based medical evidence can provide reference for clinical application of the drug.
