Tadarise-5 5mg 是一种含有他达拉非（5毫克）的药物，属于磷酸二酯酶5型抑制剂。这是一种处方药，主要用于治疗男性勃起功能障碍以及良性前列腺增生引起的症状。本文提供关于其效果、禁忌症及适用人群的客观资讯。必须强调，在考虑使用此药物前，务必咨询医生。

1. Mechanism of Action / 作用機制

Tadalafil works by inhibiting the PDE5 enzyme. This action helps relax the smooth muscles in the blood vessels of the penis during sexual stimulation, increasing blood flow to facilitate an erection. For BPH, it helps relax the smooth muscles in the prostate and bladder neck, improving urinary symptoms. It is important to note that sexual stimulation is required for it to be effective for ED; it is not an aphrodisiac.​

他达拉非通过抑制PDE5酶发挥作用。在有性刺激时，此作用有助于放松阴茎血管的平滑肌，增加血流量以促进勃起。对于前列腺增生，它有助于放松前列腺和膀胱颈部的平滑肌，改善排尿症状。需注意，用于治疗勃起功能障碍时需要性刺激才能生效；它并非催情剂。​

2. Indications (Effects) / 適應症（效果）

  • Erectile Dysfunction (ED):​ Helps men with ED achieve and maintain an erection sufficient for satisfactory sexual activity. The 5mg dose is often used for daily administration to maintain a steady concentration in the body, allowing for spontaneity.
  • Benign Prostatic Hyperplasia (BPH):​ Relieves symptoms such as frequent urination, urgency, and difficulty in urination associated with an enlarged prostate.
  • 勃起功能障碍：​ 帮助患有勃起功能障碍的男性获得并维持足以进行满意性生活的勃起。 5毫克剂量通常用于每日服用，以在体内维持稳定的药物浓度，允许自发的性活动。
    良性前列腺增生：​ 缓解与前列腺增大相关的症状，如尿频、尿急和排尿困难。

3. Suitable User Groups / 適用人群

  • Adult men diagnosed with erectile dysfunction (ED).
  • Adult men diagnosed with benign prostatic hyperplasia (BPH) experiencing lower urinary tract symptoms.
  • Patients who may benefit from a long-acting PDE5 inhibitor (effects can last up to 36 hours) or those who prefer daily low-dose therapy.
  • Important:​ Only individuals who have been evaluated by a physician and deemed suitable, with no contraindications, should use this medication.
  • 经诊断患有勃起功能障碍的成年男性。
    经诊断患有良性前列腺增生并出现下尿路症状的成年男性。
    可能受益于长效PDE5抑制剂（药效可持续长达36小时）或偏好每日低剂量治疗的患者。
    重要提示：​ 仅限经医生评估后认为适合且无禁忌症的人士使用。

4. Contraindications (Who Should NOT Use) / 禁忌人群（不應使用者）

  • Individuals allergic to Tadalafil or any component of the medication.
  • Patients currently taking any form of nitrate drugs​ (e.g., nitroglycerin for angina) or guanylate cyclase stimulators (e.g., riociguat). Concurrent use can cause a severe, life-threatening drop in blood pressure.​
  • Patients with severe cardiovascular diseases, such as unstable angina, those who have had a myocardial infarction within the last 90 days to 6 months, or stroke within the last 6 months, or patients with uncontrolled heart failure.
  • Patients with severe hypotension (low blood pressure, <90/50 mmHg) or uncontrolled hypertension.
  • This medication is not for use by women or individuals under 18 years of age.​
  • 对他达拉非或本品任何成分过敏者。
    目前正在服用任何形式的硝酸盐类药物（例如，用于治疗心绞痛的硝酸甘油）或鸟苷酸环化酶刺激剂（如利奥西呱）的患者。同时使用可能导致严重、危及生命的血压下降。​
    患有严重心血管疾病的患者，例如不稳定型心绞痛、最近90天至6个月内发生过心肌梗塞、或最近6个月内发生过中风的患者，或未受控制的心力衰竭患者。
    患有严重低血压（血压<90/50 mmHg）或未受控制的高血压患者。
    本品不适用于女性或18岁以下人士。​

5. Dosage and Administration / 用法用量

  • For ED or BPH, the usual recommended dose for daily use is 5mg taken orally at approximately the same time each day, with or without food.
  • The dosage must be determined by a physician based on the individual’s health condition, especially for patients with liver or kidney impairment.
  • Do not exceed one dose per day.​
  • 用于治疗勃起功能障碍或前列腺增生，每日服用的常规推荐剂量为5毫克，每日大约在同一时间口服，餐前或餐后均可。
    具体剂量必须由医生根据个人健康状况决定，尤其是肝肾功能不全的患者。
    每日不得超过一次剂量。​

6. Precautions and Potential Side Effects / 注意事項與潛在副作用

  • Common side effects​ may include headache, facial flushing, indigestion, nasal congestion, back pain, or muscle aches. These are usually mild and temporary.
  • Serious side effects requiring immediate medical attention​ include: sudden decrease or loss of vision or hearing, an erection lasting more than 4 hours (priapism), chest pain, or severe allergic reactions.
  • Use with caution in patients with anatomical deformation of the penis, conditions predisposing to priapism (e.g., sickle cell anemia), severe liver or kidney impairment, or retinal disorders.
  • Grapefruit or grapefruit juice may interact with Tadalafil and increase the risk of side effects.
  • It may interact with alpha-blockers (e.g., tamsulosin) or strong CYP3A4 inhibitors (e.g., ketoconazole), potentially requiring dose adjustment.
  • 常见副作用可能包括头痛、面部潮红、消化不良、鼻塞、背痛或肌肉酸痛。这些通常较轻微且是暂时性的。
    需要立即就医的严重副作用包括：视力或听力突然下降或丧失、持续超过4小时的勃起（阴茎异常勃起）、胸痛或严重过敏反应。
    阴茎解剖结构异常、易发生异常勃起的疾病（如镰状细胞贫血）、严重肝肾功能不全或视网膜病变患者应慎用。
    葡萄柚或葡萄柚汁可能与他达拉非发生相互作用，增加副作用风险。
    它可能与α-受体阻滞剂（如坦索罗辛）或强效CYP3A4抑制剂（如酮康唑）发生相互作用，可能需要调整剂量。
