Core Viewpoint - The American College of Cardiology (ACC) has officially recognized semaglutide and tirzepatide as preferred medications for obesity treatment, marking a significant shift in the management of obesity and its associated cardiovascular risks [7][10]. Summary by Sections Breakthrough Therapies - Innovative drugs like semaglutide and tirzepatide not only significantly reduce weight but also provide additional cardiovascular protection for high-risk patients, particularly those with type 2 diabetes or existing cardiovascular diseases [10]. Obesity as a Health Threat - Obesity is highlighted as a serious health risk, leading to metabolic disorders, respiratory issues, and various heart diseases. It is recognized as an independent risk factor for cardiovascular diseases [11]. Weight Loss Thresholds - Different weight loss percentages yield varying cardiovascular benefits: a 10%-15% weight loss can reduce general cardiovascular risks, while heart failure patients may need to lose over 15% for significant improvement [12]. Treatment Options - The treatment landscape includes lifestyle interventions, weight loss surgery, and pharmacotherapy. The ACC suggests a reevaluation of the traditional approach of prioritizing lifestyle changes before medication [15]. Third-Generation Weight Loss Drugs - Semaglutide and tirzepatide represent a revolutionary choice in obesity management, with long-term efficacy and safety data supporting their use for weight loss [16]. Weight Loss Effectiveness - Comparative data shows that semaglutide leads to an average weight loss of 14.9%, while tirzepatide achieves an average of 20.9%, making it the most effective option currently available [18][20]. Long-Term Treatment Importance - Long-term treatment is crucial as stopping medication can lead to weight regain. Continuous use combined with lifestyle adjustments is essential for maintaining weight loss [21]. Accessibility and Economic Burden - The main challenges for semaglutide and tirzepatide include limited supply and high costs, which may affect patient access to these therapies [22]. Cardiovascular Benefits Beyond Weight Loss - The NuSH therapy not only aids in weight loss but also reduces the risk of heart attacks and strokes in obese patients without diabetes, and improves outcomes for heart failure patients [23]. Approved Weight Loss Medications in China - The 2024 guidelines in China have approved five medications for adult weight loss, emphasizing a multidisciplinary approach to obesity treatment [24].

Core Insights - The article discusses the introduction of Daliresp, a new generation insomnia treatment, at the 2025 China International Import Expo, highlighting its potential to reshape the insomnia treatment landscape in China, where nearly 48.5% of adults experience sleep issues [1][6]. Group 1: Traditional Insomnia Treatments - Traditional insomnia medications often lead to dependency and residual effects, causing patients to face a dilemma between sleeplessness and poor next-day performance [2][4]. - Long-term use of conventional sedatives can result in tolerance, requiring higher doses for the same effect, and about 30% of users may experience withdrawal symptoms upon cessation [2][4]. Group 2: Mechanism of Daliresp - Daliresp operates as a dual orexin receptor antagonist (DORA), targeting the orexin system that regulates wakefulness and sleep, thus promoting natural sleep without broadly suppressing brain activity [3][4]. - Clinical studies have shown that Daliresp significantly improves sleep onset and maintenance while not altering sleep structure, which distinguishes it from traditional sedatives [4][5]. Group 3: Clinical Data and Efficacy - In clinical trials, Daliresp reduced sleep onset time by 35 minutes and wake time after sleep onset by 30 minutes, extending total sleep time by one hour without increasing next-day drowsiness [5]. - The drug has shown consistency in effectiveness and safety in both Chinese and overseas clinical studies, with no evidence of dependency or rebound insomnia [5]. Group 4: Market Potential and Competitive Advantages - The Chinese sleep health market exceeds 300 billion yuan and continues to grow, presenting a significant opportunity for Daliresp to capture market share due to its unique mechanism and clinical advantages [6][7]. - Daliresp's safety profile, low dependency risk, and alignment with normal sleep cycles make it appealing to both doctors and patients, enhancing treatment adherence [6][7]. Group 5: Local Production and Accessibility - Local production of Daliresp is expected to reduce costs and improve patient accessibility, addressing the challenges of high prices and supply chain uncertainties associated with imported drugs [8][9]. - The production facility in Hainan is set to achieve an annual capacity of 600 million tablets, ensuring a stable supply for insomnia patients [9]. Group 6: Transformation in Insomnia Treatment - The introduction of Daliresp signifies a shift in insomnia treatment from forced sleep to natural sleep, emphasizing overall sleep health management rather than just symptom control [10]. - As awareness of sleep health increases, medications like Daliresp that target specific physiological mechanisms will play a crucial role in this evolving treatment paradigm [10].
