近年来，随着社会压力的增加和生活节奏的加快，抑郁症的患病率呈现上升趋势。抑郁症不仅给患者带来了巨大的痛苦，也对社会和经济造成了深远的影响。面对如此庞大的患者群体，抗抑郁药物市场的需求也在不断增长。 抗抑郁药的药店零售市场波动趋势分析 据中国医药工业信息中心RPDB药品零售数据库统计，近五年来，抗抑郁药零售市场销售额先升后降，2022年药店（放大）终端的销售额最高，达1482万元，其余年份稳定在1400万元左右。2024年，其销售额为1365万元，同比下降1.03％。 图1 中国药店（放大）终端抗抑郁药销售情况 数据来源：RPDB药品零售数据库，中国医药工业信息中心 抗抑郁药TOP10 抗抑郁药物种类繁多，主要包括氟西汀、舍曲林、帕罗西汀为代表的选择性5-羟色胺再摄取抑制剂（SSRIs）；文拉法辛、度洛西汀为代表的5-羟色胺和去甲肾上腺素再摄取抑制剂（SNRIs）；以阿米替林为代表的三环类抗抑郁药（TCAs）；以苯乙肼为代表的单胺氧化酶抑制剂（MAOIs）；以米氮平、安非他酮为代表的非典型抗抑郁药等。根据中国医药工业信息中心RPDB数据库统计，2024年零售市场销售额排名前十的药物中，氟哌噻吨＋美利曲辛，复方跃居第一位，销售额达423.98百万元。 图2 2024年中国药店（放大）销售额TOP10药物 数据来源：RPDB药品零售数据库，中国医药工业信息中心 抗抑郁药物核心市场 据估计，全球10-19岁人群中，有超过七分之一（约14%）的人患有精神障碍。然而，这些疾病在很大程度上仍不为人知，也未能得到有效的治疗。青少年的心理健康问题不仅影响个体的发展，也难以满足社会对高素质人才的需求。这种背景下，抗抑郁药物市场一直是全球医药行业的重要组成部分。 在国内市场，抗抑郁药物的竞争格局逐渐清晰。跨国药企如辉瑞、灵北制药等凭借原研药优势和强大的市场推广能力，长期占据较大市场份额，形成第一梯队。而国内大型药企如豪森药业、华海药业、科伦药业等通过仿制药一致性评价和集采中标等方式，逐渐提升市场影响力，构成了第二梯队。 抗抑郁药物市场的发展趋势 ● 市场需求增长：随着抑郁症患者数量的增加以及公众对心理健康问题的重视，抗抑郁药物的市场需求将持续增长。 ● 本土药企崛起：经过多轮国家带量采购，本土仿制药企凭借更具竞争力的价格和不断优化的产品质量，逐步占据了更大的市场份额。 ● 创新药物研发：跨国药企和本土药企都在加大对创新药物的研发投入，以满足不同患者的需求。 ● 政策支持：国家对精神卫生问题的重视，以及医保政策的不断完善，将进一步推动抗抑郁药物市场的发展。如国务院印发的《健康中国行动（2019—2030年）》中，心理健康促进行动是其中的重要内容。该行动明确了到2022年和2030年的具体目标，包括提升居民心理健康素养水平到20%和30%，减缓抑郁症、焦虑障碍、失眠障碍等心理相关疾病的上升趋势。 2024年国家医保药品目录新增纳入了多款抗抑郁药物，如绿叶制药的若欣林®（盐酸托鲁地文拉法辛缓释片），这是我国首个自主研发的抗抑郁化药1类创新药。根据中国医药工业信息中心RPDB数据库统计，托鲁地文拉法辛缓释片在国内上市后销售额一路上涨，2023年在中国药店终端销售额超过207.7万元，同比增长为32%；2024年销售额超过264.8万元，同比增长27.51%。 图3 2023-2024年若欣林零售（放大市场）销售额 数据来源：RPDB药品零售数据库，中国医药工业信息中心 抑郁症是现代社会中一个亟待解决的公共健康问题，而抗抑郁药物市场的发展则为患者提供了更多的治疗选择。随着市场需求的增长、本土药企的崛起以及创新药物的研发，抗抑郁药物市场将迎来更大的发展机遇。未来，我们期待更多安全、有效的抗抑郁药物问世，以帮助抑郁症患者重获健康。  喜欢我们文章的朋友点个“在看”和“赞”吧，不然微信推送规则改变，有可能每天都会错过我们哦~ 免责声明 “汇聚南药”公众号所转载文章来源于其他公众号平台，主要目的在于分享行业相关知识，传递当前最新资讯。图片、文章版权均属于原作者所有，如有侵权，请在留言栏及时告知，我们会在24小时内删除相关信息。 信息来源：医药地理 往期推荐 本平台不对转载文章的观点负责，文章所包含内容的准确性、可靠性或完整性提供任何明示暗示的保证。

New Analyses Related to Aficamten Expand on its Metabolism Pathways, Treatment Effect Associated with Combination Therapy with Disopyramide and Longer-Term Effect on Cardiac Structure and Function SOUTH SAN FRANCISCO, Calif., March 17, 2025 (GLOBE NEWSWIRE) -- Cytokinetics, Incorporated (Nasdaq: CYTK) today announced five presentations related to aficamten, an investigational cardiac myosin inhibitor, and hypertrophic cardiomyopathy (HCM), at the American College of Cardiology (ACC) Annual Scientific Session & Expo taking place from March 29, 2025–March 31, 2025 in Chicago, IL. “We are pleased to be sharing several new analyses relating to aficamten at the upcoming ACC Scientific Session & Expo,” said Stephen Heitner, M.D., Vice President, Head of Clinical Research. “The presentations describe the drug metabolism of aficamten, the safety of combination therapy with the standard of care medication disopyramide, and the effect of longer-term use of aficamten. Together these analyses add to the strong and growing evidence base supporting the potential for aficamten in patients with obstructive HCM and inform how it may be used in clinical practice.” Evaluation of Cytochrome P450 2C9, 2C19, and 2D6 Inhibition on the Pharmacokinetics of Aficamten in Healthy Participants (1091-139) Poster Presentation, March 29, 2025, 2:00-3:00 PM CT, South Hall. Neha Maharao, Ph.D., Senior Clinical Pharmacologist, Cytokinetics. Data from an open-label, fixed-sequence drug-drug interaction (DDI) study of aficamten in healthy participants will be presented in a poster presentation. A previous study showed that aficamten is metabolized, in part, by the cytochrome P450 (CYP) enzyme 3A41. To further characterize its metabolic pathways, aficamten was evaluated with concomitant administration of three strong inhibitors of one or more of the CYP pathways: fluconazole (inhibitor of 2C9, 2C19, and 3A4), paroxetine (inhibitor of 2D6) and fluoxetine (inhibitor of 2C19 and 2D6). The data show that aficamten was eliminated by multiple CYP pathways, primarily by CYP2C9 (fraction metabolized [fm]=50%), with contributions from CYP3A (fm=26%), CYP2D6 (fm=21%) and CYP2C19 (fm=3%). Safety and Outcomes of Concomitant Aficamten and Disopyramide Use and Withdrawal in Patients with Obstructive Hypertrophic Cardiomyopathy: An Analysis of REDWOOD-HCM Cohort 3, SEQUOIA-HCM, and FOREST-HCM Trials (411-06) Oral Presentation, March 31, 2025, 9:11-9:18 AM CT, S406b. Ahmad Masri, M.D., MS, Director of the Hypertrophic Cardiomyopathy Center at Oregon Health & Science University. Data from an analysis of concomitant treatment with aficamten and disopyramide from completed and ongoing clinical trials of aficamten in patients with obstructive HCM will be presented in an oral presentation. The analysis included 50 participants from Cohort 3 of REDWOOD-HCM (Randomized Evaluation of Dosing With CK-274 in Obstructive Outflow Disease in HCM), SEQUOIA-HCM (Safety, Efficacy, and Quantitative Understanding of Obstruction Impact of Aficamten in HCM) and FOREST-HCM (Follow-up, Open-Label, Research Evaluation of Sustained Treatment with Aficamten in HCM) who were receiving disopyramide at baseline. Participants were separated into four groups: those on disopyramide who underwent withdrawal of aficamten due to end of treatment in Cohort 3 of REDWOOD-HCM or SEQUOIA-HCM (n=29), patients on disopyramide receiving placebo in SEQUOIA-HCM (n=20), patients on aficamten who underwent disopyramide withdrawal in FOREST-HCM (n=17) and patients on aficamten who maintained treatment with disopyramide in FOREST-HCM (n=27). Combination therapy with aficamten and disopyramide was well-tolerated; the analysis suggests that combination of disopyramide with aficamten did not result in lower left ventricular outflow tract (LVOT) gradients compared to treatment with aficamten alone. The analysis suggests that withdrawal of disopyramide while receiving aficamten did not reduce the efficacy of aficamten and further that withdrawal of aficamten while on disopyramide resulted in the return of LVOT obstruction and symptoms, with an increase in NT-proBNP. There were no safety events reported with either aficamten or disopyramide withdrawal, and no episodes of atrial fibrillation after disopyramide withdrawal were reported. Effect of Aficamten Treatment for Up to 72 Weeks on Cardiac Structure and Function in Patients with Obstructive Hypertrophic Cardiomyopathy: The SEQUOIA-HCM and FOREST-HCM CMR Sub-studies (964-09) Moderated Poster Presentation, March 30, 2025, 12:06-12:13 PM CT, Theater 5. Ahmad Masri, M.D., MS, Director of the Hypertrophic Cardiomyopathy Center at Oregon Health & Science University. New data from the cardiac magnetic resonance (CMR) imaging sub-studies of FOREST-HCM and SEQUOIA-HCM will be presented in a moderated poster presentation. At the time of the current analysis, 64 patients had completed a baseline CMR, including 36 patients who had completed a follow-up CMR at 72 weeks, and 28 patients who had completed a follow-up CMR at 48 weeks. Longer-term treatment with aficamten resulted in statistically significant improvements (mean ±SD) in measures of cardiac structure and function including left ventricular mass index (-9.8 g/m2 ±18.1, p<0.0001), maximum left ventricular septal wall thickness (-2.4 mm ±2.3, p<0.0001), left atrial volume (-17.9 ml ±28.3, p<0.0001) and mitral regurgitant volume (-18.1 ml ±19.2, p<0.0001) and fraction (-14.2% ±15.6, p<0.0001). These changes were accompanied by stable replacement fibrosis (late gadolinium enhancement mass = -0.3 g ±5.0, p=0.51) and reduced interstitial fibrosis (global extracellular volume (ECV) = -1.2 % ±2.8, p = 0.002; Native T1 = -36.6 ms ±55.7, p<0.0001). Understanding the Impact of Placebo on Patient-Reported Health Status: An Analysis from SEQUOIA-HCM (1029-176) Poster Presentation, March 29, 2025, 9:30-10:30 AM CT, South Hall. Charles F. Sherrod, M.D., M.Sc., Cardiology Fellow, UMKC Healthcare Institute for Innovations in Quality, Saint Luke’s Mid America Heart Institute. A new analysis from SEQUOIA-HCM of the placebo effect on Kansas City Cardiomyopathy Questionnaire Overall Summary Scores (KCCQ-OSS) will be presented in a poster presentation. In patients randomized to placebo in SEQUOIA-HCM, the change in KCCQ-OSS was evaluated from baseline to Week 24 and following blinded treatment withdrawal from Week 24 to Week 28. Among the 140 (47%) patients on placebo, the median KCCQ-OSS at baseline was 67.2 (95% CI: 62.9, 71.5) and the median improvement at Week 24 was 5.7 points (95% CI: 3.2, 8.3; p<0.01). After withdrawal from Week 24 to Week 28, the median score decreased by only 2.1 points (95% CI: -3.5, -0.7; p<0.01). These results suggest that about one-third of the improvement observed in KCCQ-OSS in patients receiving placebo was due to a placebo effect, further suggesting that other changes in health status following treatment with placebo may be due to other factors involved in clinical trial participation, such as receiving treatment at expert centers and changes in patient behavior. Association Between Race/Ethnicity and Outcomes in Patients with Non-Obstructive Hypertrophic Cardiomyopathy (1251-173) Poster Presentation, March 31, 2025, 10:30-11:30 AM CT, South Hall. Nosheen Reza, M.D., Assistant Professor of Medicine, Division of Cardiovascular Medicine, the Hospital of the University of Pennsylvania. Data from a new health economics and outcomes research (HEOR) analysis of the association between race/ethnicity and outcomes in non-obstructive HCM patients will be presented in a poster presentation. This retrospective cohort study included adult patients diagnosed with non-obstructive HCM from January 1, 2013 to December 31, 2021. Of the 9,842 patients included, 74.2% were non-Hispanic white, 19.5% were non-Hispanic Black/African American, 4.2% were Hispanic and 2.1% were non-Hispanic Asian. White patients had greater rates of atrial fibrillation and cardiovascular hospitalization compared to Asian and Hispanic patients. Compared to white patients, Black patients had increased rates of stroke (risk ratio [RR] 1.76), heart failure (RR 1.73), ventricular tachycardia (RR 1.24), sudden cardiac arrest (RR 1.90), cardiovascular hospitalization (RR 1.42) and cardiovascular rehospitalization (RR 1.31) and a lower rate of atrial fibrillation (RR 0.74; all p<0.001). All-cause mortality was highest among Black patients (p<0.001). Compared to white patients, non-Hispanic Black patients had the highest rate of adverse cardiovascular outcomes and all-cause mortality, while Asian and Hispanic patients experienced lower rates. These results highlight an urgent need to address drivers of race/ethnicity-based disparities in patients with nHCM. About Aficamten Aficamten is an investigational selective, small molecule cardiac myosin inhibitor discovered following an extensive chemical optimization program that was conducted with careful attention to therapeutic index and pharmacokinetic properties and as may translate into next-in-class potential in clinical development. Aficamten was designed to reduce the number of active actin-myosin cross bridges during each cardiac cycle and consequently suppress the myocardial hypercontractility that is associated with HCM. In preclinical models, aficamten reduced myocardial contractility by binding directly to cardiac myosin at a distinct and selective allosteric binding site, thereby preventing myosin from entering a force producing state. The development program for aficamten is assessing its potential as a treatment that improves exercise capacity as measured by peak oxygen uptake (pVO2) and relieves symptoms in patients with HCM. Aficamten was evaluated in SEQUOIA-HCM, a positive pivotal Phase 3 clinical trial in patients with symptomatic obstructive hypertrophic cardiomyopathy (HCM). Aficamten received Breakthrough Therapy Designation for the treatment of symptomatic obstructive HCM from the U.S. Food & Drug Administration (FDA) and from the National Medical Products Administration (NMPA) in China. Aficamten is currently under regulatory review in the U.S, where the FDA is reviewing a New Drug Application (NDA) for aficamten, which was assigned standard review and a Prescription Drug User Fee Act (PDUFA) target action date of September 26, 2025. Additionally, the European Medicines Agency (EMA) is reviewing a Marketing Authorization Application (MAA) for aficamten, and The Center for Drug Evaluation (CDE) of the China National Medical Products Administration (NMPA) is reviewing an NDA for aficamten with Priority Review. Aficamten is also currently being evaluated in MAPLE-HCM, a Phase 3 clinical trial of aficamten as monotherapy compared to metoprolol as monotherapy in patients with obstructive HCM; ACACIA-HCM, a Phase 3 clinical trial of aficamten in patients with non-obstructive HCM; CEDAR-HCM, a clinical trial of aficamten in a pediatric population with obstructive HCM; and FOREST-HCM, an open-label extension clinical study of aficamten in patients with HCM. About Hypertrophic Cardiomyopathy Hypertrophic cardiomyopathy (HCM) is a disease in which the heart muscle (myocardium) becomes abnormally thick (hypertrophied). The thickening of cardiac muscle leads to the inside of the left ventricle becoming smaller and stiffer, and thus the ventricle becomes less able to relax and fill with blood. This ultimately limits the heart’s pumping function, resulting in reduced exercise capacity and symptoms including chest pain, dizziness, shortness of breath, or fainting during physical activity. HCM is the most common monogenic inherited cardiovascular disorder, with approximately 280,000 patients diagnosed, however, there are an estimated 400,000-800,000 additional patients who remain undiagnosed in the U.S.2,3,4 Two-thirds of patients with HCM have obstructive HCM (oHCM), where the thickening of the cardiac muscle leads to left ventricular outflow tract (LVOT) obstruction, while one-third have non-obstructive HCM (nHCM), where blood flow isn’t impacted, but the heart muscle is still thickened. People with HCM are at high risk of also developing cardiovascular complications including atrial fibrillation, stroke and mitral valve disease.5 People with HCM are at risk for potentially fatal ventricular arrhythmias and it is one of the leading causes of sudden cardiac death in younger people or athletes.6 A subset of patients with HCM are at high risk of progressive disease leading to dilated cardiomyopathy and heart failure necessitating cardiac transplantation.
