一、药物基本属性

二、核心功效与临床应用

(基于其历史应用和宣称的药理作用,但需强调其证据不足且当前无合法临床应用)

  1. 慢性静脉功能不全 (CVI) 相关症状的缓解:
    • 宣称可减轻腿部沉重感、疼痛、夜间痉挛感。
    • 宣称可减轻功能性症状(如感觉异常)和减少踝部及下肢水肿。
    • 作用机制宣称: 增强静脉壁张力/收缩性、降低毛细血管通透性(减少渗出)、改善微循环血流、促进淋巴引流、抑制炎症介质释放、抗氧化保护血管内皮。
  2. 痔疮急性发作的症状治疗:
    • 宣称可缓解痔疮引起的疼痛、出血、瘙痒和肿胀。
    • 作用机制宣称: 改善肛门直肠区域的静脉张力和微循环,减轻充血和炎症反应。

重要提示: 上述临床应用均基于其药理作用推测和历史有限的临床研究,缺乏现代高质量循证医学证据的强有力支持。目前没有权威指南推荐其用于这些适应症。其有效性存在显著争议。

三、使用禁忌与注意事项

(基于其化学类别、同类药物经验及有限的历史报告)

重要医疗建议强调

黄酮酸(黄酮酸钠)目前在全球主要药品市场(包括中国、美国、欧盟)已无合法上市销售,且其临床有效性证据不足。因此,在现代临床实践中,该药物已不具备治疗价值,不应被处方或使用。如果您遇到慢性静脉功能不全或痔疮等相关症状,请务必咨询专业的医生(如血管外科医生、普通外科医生或全科医生)。医生会根据您的具体情况、最新临床指南和循证医学证据,为您推荐经过验证、安全有效的治疗方案(如加压疗法、生活方式调整、或已证实有效的其他静脉活性药物/手术治疗)。切勿自行寻找或使用已退市或未经充分验证的药物。

  1. European Medicines Agency (EMA) Assessment Reports (Historical): While not specifically for Flavodic Acid/Sodium Flavodate, EMA's assessments of related flavonoid drugs (like Diosmin, MPFF) provide context on the class, regulatory requirements, and evidence standards. These reports highlight the limited evidence for many older flavonoid preparations. (Search EMA website for specific products containing Diosmin/MPFF).
  2. Pharmacopées (e.g., French Pharmacopoeia - Historical Editions): May have contained monographs for Sodium Flavodate or products containing it (e.g., Flavungor), providing basic chemical and pharmaceutical information. (Access requires historical archives).

    • Example (Illustrative, specific high-quality studies lacking): Boisseau, M. R., et al. (1995). Fibrinolysis and flavonoids. Biomedicine & Pharmacotherapy, 49(10), 453-458. (Discusses flavonoids in general, including potential mechanisms relevant to claimed effects of compounds like sodium flavodate, but not specific evidence for it).

(Discusses MPFF, a different flavonoid fraction; sometimes older reviews might briefly mention sodium flavodate as part of the historical landscape but not endorse it).

French National Agency for Medicines and Health Products Safety (ANSM) - Historical Data: ANSM would have been responsible for the authorization and pharmacovigilance of Flavungor (sodium flavodate) in France prior to its discontinuation. Public assessment reports or withdrawal notices might exist in archives but are difficult to access and likely cite insufficient evidence or commercial reasons for withdrawal. (Search ANSM website archives if available).

总结关键参考文献观点: 权威文献(EMA评估、现代临床指南、系统性综述)均未支持黄酮酸/黄酮酸钠的临床应用价值。其历史存在是基于有限且质量不高的早期研究,其药理作用主要依据黄酮类化合物的共性推测。该药物因缺乏确凿的有效性证据和/或商业原因已在主要市场退市多年,在现代循证医学框架下被视为无效或证据不足的药物,无合法临床应用地位。所有信息均指向其属于限制使用药(H3)无合法临床应用药物(U)
