            <strong>[[泽珂]]([[Zytiga]])</strong>，通用名为<strong>[[醋酸阿比特龙]]([[Abiraterone Acetate]])</strong>，研发代码为<strong>[[CB7598]]</strong>，是由[[强生]]([[Johnson & Johnson]])旗下[[杨森制药]]([[Janssen]])研发的一种口服、选择性、不可逆的<strong>[[CYP17抑制剂]]</strong>。作为前列腺癌内分泌治疗的里程碑药物，[[泽珂]]通过阻断睾丸、肾上腺及肿瘤微环境中的雄激素生物合成，在2026年的诊疗体系中仍是<strong>[[转移性激素敏感性前列腺癌]]([[mHSPC]])</strong>及<strong>[[转移性去势抵抗性前列腺癌]]([[mCRPC]])</strong>的标准方案。该药必须与<strong>[[泼尼松]]</strong>（或[[泼尼松龙]]）联用，以平衡其引起的盐皮质激素过量副作用。

    <p style="margin: 15px 0; text-align: justify;">
        [[泽珂]]通过不可逆地抑制<strong>[[CYP17]]</strong>（17α-羟化酶和17,20-裂解酶）发挥药效，这一酶复合体是雄激素合成通路的关键节点。其2026年药理学研究将其特点概括为：
    </p>
    <ul style="padding-left: 25px; color: #334155;">
        <li style="margin-bottom: 12px;"><strong>切断剩余雄激素来源：</strong> 传统去势（[[ADT]]）仅能抑制睾丸来源的雄激素，而[[泽珂]]能进一步阻断肾上腺及肿瘤病灶自身（自分泌）产生的雄激素，将体内雄激素水平降至“极致”。</li>
        <li style="margin-bottom: 12px;"><strong>泼尼松的必要代偿：</strong> 抑制[[CYP17]]会导致[[皮质醇]]水平下降，引发反馈性[[ACTH]]升高，从而引起[[盐皮质激素]]蓄积。联用<strong>[[泼尼松]]</strong>可补充糖皮质激素并抑制ACTH，预防高血压及低钾血症。</li>
        <li style="margin-bottom: 12px;"><strong>克服 AR 通路激活：</strong> 2026年分子模型显示，[[泽珂]]能有效应对因雄激素前体物质代偿性上调引发的<strong>[[去势抵抗]]</strong>进程。</li>
