1. Product Positioning and Mechanism of Action
Climax延时喷剂是一种局部外用喷雾剂，核心成分为利多卡因（Lidocaine），属于局部麻醉药物类别。其作用机制是通过降低阴茎龟头及冠状沟区域的皮肤敏感度，延长性刺激的耐受时间，从而改善早泄（PE）问题。与口服药物不同，该产品采用靶向局部起效方式，药物仅作用于喷洒区域，不会进入全身血液循环，从而减少系统性副作用风险。
Climax delay spray is a topically applied spray whose core ingredient is Lidocaine, belonging to the class of local anesthetics. Its mechanism of action involves reducing the sensitivity of the glans penis and coronary sulcus area, thereby prolonging tolerance to sexual stimulation and improving premature ejaculation (PE) issues. Unlike oral medications, this product adopts a targeted local action approach, where the drug acts only on the applied area without entering systemic circulation, thus reducing the risk of systemic side effects.
利多卡因作为一种钠通道阻滞剂，可暂时抑制局部神经信号传导。临床研究显示，其起效时间约为5-10分钟，持续效果可达30-60分钟。这种快速起效特性使其适合按需使用，无需像口服药物那样需提前规划服药时间。
As a sodium channel blocker, Lidocaine temporarily inhibits local nerve signal transmission. Clinical studies show its onset of action is approximately 5-10 minutes, with effects lasting 30-60 minutes. This rapid onset characteristic makes it suitable for on-demand use, unlike oral medications that require advanced dosing planning.
二、成分科学与制剂创新
2. Ingredient Science and Formulation Innovation
除主要活性成分利多卡因外，Climax喷剂还含有辅助成分如丁基苯酚和异丙基苯酚，这些化合物作为溶剂和稳定剂，确保药物均匀释放。部分版本添加植物提取物如冬樱花（Ashwagandha） 与黧豆（Kwanch Beej），这些成分在传统医学中用于增强性功能，但其临床效果仍需更多研究验证。
In addition to the primary active ingredient Lidocaine, Climax spray contains auxiliary components such as butylphenol and isopropylphenol, which act as solvents and stabilizers to ensure consistent drug release. Some versions add plant extracts like Ashwagandha and Kwanch Beej, traditionally used in enhancing sexual function, though their clinical efficacy requires further research validation.
制剂采用微乳化技术提高生物利用度，使药物能够快速穿透皮肤角质层。喷雾装置经过特殊设计，可精准控制剂量，每次喷洒释放约7-10mg药液，避免过量使用导致的过度麻木。
The formulation utilizes microemulsion technology to enhance bioavailability, enabling rapid penetration through the skin’s stratum corneum. The spray device is specially designed for precise dosing, releasing approximately 7-10mg of solution per spray to avoid excessive numbness from overdose.
三、使用方案与效果特性
3. Usage Protocol and Efficacy Characteristics
标准使用流程如下：
- 性活动前15-30分钟，摇匀后距皮肤15cm喷洒
- 重点覆盖龟头与冠状沟区域，每次1-2喷即可
- 轻轻按摩促进吸收，待麻木感适中后即可进行性活动
- 使用后30分钟可正常清洗，不影响效果
Standard usage procedure is as follows:
- Shake well and spray from 15cm away from the skin 15-30 minutes before sexual activity
- Focus coverage on the glans and coronary sulcus, 1-2 sprays sufficient
- Gently massage to promote absorption; proceed when numbness is moderate
- Normal washing is possible after 30 minutes without affecting efficacy
- 效果呈现剂量依赖性：
- 低剂量（1喷）：延长性交时间5-10分钟，适合初次使用者
- 中剂量（2喷）：延长10-20分钟，适用于中度早泄患者
- 高剂量（3喷及以上）：延长20分钟以上，但可能影响勃起硬度
- Effects show a dose-dependent response:
- Low dose (1 spray): Extends intercourse time by 5-10 minutes, suitable for first-time users
- Medium dose (2 sprays): Extends by 10-20 minutes, for moderate PE patients
- High dose (3+ sprays): Extends beyond 20 minutes, but may affect erection firmness
四、临床优势与局限性分析
4. Clinical Advantages and Limitations Analysis
核心优势包括：
- 快速起效：较口服PDE5抑制剂（需30-60分钟）更具灵活性
- 局部作用：避免全身性副作用如头痛、面部潮红
- 可调节性：通过喷洒次数灵活控制麻醉强度
- 非激素配方：不影响内分泌系统正常功能
Core advantages include:
- Rapid onset: More flexible than oral PDE5 inhibitors (requiring 30-60 minutes)
- Local action: Avoids systemic side effects like headaches, facial flushing
- Adjustability: Flexible control of anesthesia intensity via spray count
- Non-hormonal formula: Does not affect normal endocrine system function
存在的局限性：
- 可能转移至伴侣体内，导致阴道麻木（发生率12-18%）
- 过度使用可能影响勃起质量
- 不解决早泄的心理成因
- 长期使用可能产生耐受性（6个月后效果下降15-20%）
Existing limitations:
- Potential transfer to partner, causing vaginal numbness (incidence 12-18%)
- Overuse may affect erection quality
- Does not address psychological causes of PE
- Tolerance may develop with long-term use (15-20% efficacy reduction after 6 months)
五、安全性规范与适用人群
5. Safety Guidelines and Target Population
适用人群特征：
- 原发性或继发性早泄患者
- 口服药物禁忌者（如心血管疾病患者）
- 追求快速起效与短期效果的人群
- 年龄18-65岁，无局部皮肤破损者
Target population characteristics:
- Patients with primary or secondary premature ejaculation
- Those contraindicated for oral medications (e.g., cardiovascular patients)
- Individuals seeking rapid onset and short-term effects
