二、作用机制与特点 / Mechanism and Features

作用机制：

伐地那非通过抑制PDE5酶，增加cGMP（环磷酸鸟苷）​ 水平，促使阴茎海绵体平滑肌松弛，显著提升血流量，从而在性刺激下自然引发勃起。

核心优势：

  1. 快速起效：通常可在30-60分钟内起效，效果可持续4-5小时。
  2. 受饮食影响小：与高脂肪食物同服时，吸收效率仍较稳定。
  3. 作用自然：仅在性刺激下生效，符合生理性反应。

Mechanism:

Vardenafil inhibits the PDE5 enzyme, increasing cGMP levels​ and relaxing smooth muscles in the penile corpus cavernosum. This significantly enhances blood flow, naturally facilitating an erection with sexual stimulation.

Key Advantages:

  1. Fast-Acting: Typically takes effect within 30-60 minutes, with results lasting 4-5 hours.
  2. Less Affected by Food: Absorption remains relatively stable even when taken with high-fat meals.

    • 24小时内不超过一次，避免连续服用。
  3. 关键提示：
    • 需性刺激才能起效；
    • 避免与葡萄柚汁同服，以免增加副作用风险。
  4. Timing: Take orally 30-60 minutes​ before sexual activity, with or without food.
  5. Dosage Adjustment:
    • Start with half a tablet (10mg), adjusting to a full tablet (20mg) based on response.
    • Do not exceed one dose within 24 hours; avoid consecutive days.
