Tadarise-5 5mg 是一種含有他達拉非（5毫克）的藥物，屬於磷酸二酯酶5型抑制劑。這是一種處方藥，主要用於治療男性勃起功能障礙以及良性前列腺增生引起的症狀。本文提供關於其效果、禁忌症及適用人群的客觀資訊。必須強調，在考慮使用此藥物前，務必諮詢醫生。

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.​

他達拉非通過抑制PDE5酶發揮作用。在有性刺激時，此作用有助於放鬆陰莖血管的平滑肌，增加血流量以促進勃起。對於前列腺增生，它有助於放鬆前列腺和膀胱頸部的平滑肌，改善排尿症狀。需注意，用於治療勃起功能障礙時需要性刺激才能生效；它並非催情劑。​

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.
  • 勃起功能障礙：​ 幫助患有勃起功能障礙的男性獲得並維持足以進行滿意性生活的勃起。5毫克劑量通常用於每日服用，以在體內維持穩定的藥物濃度，允許自發的性活動。
  • 良性前列腺增生：​ 緩解與前列腺增大相關的症狀，如尿頻、尿急和排尿困難。

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.
  • 經診斷患有勃起功能障礙的成年男性。
  • 經診斷患有良性前列腺增生並出現下尿路症狀的成年男性。
  • 可能受益於長效PDE5抑制劑（藥效可持續長達36小時）或偏好每日低劑量治療的患者。
  • 重要提示：​ 僅限經醫生評估後認為適合且無禁忌症的人士使用。

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.​
  • 對他達拉非或本品任何成分過敏者。
  • 目前正在服用任何形式的硝酸鹽類藥物（例如，用於治療心絞痛的硝酸甘油）或鳥苷酸環化酶刺激劑（如利奧西呱）的患者。同時使用可能導致嚴重、危及生命的血壓下降。​
  • 患有嚴重心血管疾病的患者，例如不穩定型心絞痛、最近90天至6個月內發生過心肌梗塞、或最近6個月內發生過中風的患者，或未受控制的心力衰竭患者。
  • 患有嚴重低血壓（血壓<90/50 mmHg）或未受控制的高血壓患者。
  • 本品不適用於女性或18歲以下人士。​

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.​
  • 用於治療勃起功能障礙或前列腺增生，每日服用的常規推薦劑量為5毫克，每日大約在同一時間口服，餐前或餐後均可。
  • 具體劑量必須由醫生根據個人健康狀況決定，尤其是肝腎功能不全的患者。
  • 每日不得超過一次劑量。​

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.
  • 常見副作用可能包括頭痛、面部潮紅、消化不良、鼻塞、背痛或肌肉酸痛。這些通常較輕微且是暫時性的。
  • 需要立即就醫的嚴重副作用包括：視力或聽力突然下降或喪失、持續超過4小時的勃起（陰莖異常勃起）、胸痛或嚴重過敏反應。
  • 陰莖解剖結構異常、易發生異常勃起的疾病（如鐮狀細胞貧血）、嚴重肝腎功能不全或視網膜病變患者應慎用。
  • 葡萄柚或葡萄柚汁可能與他達拉非發生相互作用，增加副作用風險。
  • 它可能與α-受體阻滯劑（如坦索羅辛）或強效CYP3A4抑制劑（如酮康唑）發生相互作用，可能需要調整劑量。
