POXET 60: A Scientific Approach to Understanding Premature Ejaculation Treatment
1. Drug Overview and Basic Understanding
POXET 60是一种专门治疗早泄（PE）的药物，其活性成分为盐酸达泊西汀（Dapoxetine Hydrochloride）。该药物由印度Sunrise公司生产，每片含有60毫克达泊西汀，是当前早泄治疗领域的重要选择之一。
POXET 60 is a specialized medication for treating premature ejaculation (PE), with the active ingredient being Dapoxetine Hydrochloride. Produced by the Indian company Sunrise, each tablet contains 60mg of Dapoxetine, making it one of the significant options in the current PE treatment landscape。
Click to buy达泊西汀是一种短效选择性5-羟色胺再摄取抑制剂（SSRI），是首个专门为早泄治疗研发的药物。与需要每日服用的抗抑郁药不同，达泊西汀采用”按需”服药方案，在性生活前特定时间服用即可发挥效果。
Dapoxetine is a short-acting selective serotonin reuptake inhibitor (SSRI) and the first medication specifically developed for premature ejaculation treatment. Unlike antidepressants that require daily administration, Dapoxetine employs an “on-demand” dosing regimen, taken at a specific time before sexual activity。
二、药理作用与科学机制
2. Pharmacological Action and Scientific Mechanism
POXET 60的核心作用机制基于神经递质调节。达泊西汀通过抑制神经元对5-羟色胺的再吸收，增加神经突触间隙内的5-羟色胺浓度，从而增强射精控制能力。
The core mechanism of action of POXET 60 is based on neurotransmitter regulation. By inhibiting the reuptake of serotonin by neurons, Dapoxetine increases serotonin concentration in the synaptic cleft, thereby enhancing ejaculatory contro。
从生理学角度分析，射精过程主要由交感神经系统介导。达泊西汀通过作用于脊髓射精反射中心和大脑相关区域（如外侧巨细胞旁核），调节射精驱动反射，延长射精潜伏期。
From a physiological perspective, the ejaculation process is primarily mediated by the sympathetic nervous system. Dapoxetine acts on the spinal ejaculation reflex center and related brain areas (such as the lateral paragigantocellular nucleus) to modulate the ejaculatory drive reflex and prolong ejaculation latency。

三、适用人群与剂量方案
3. Suitable Population and Dosage Regimen
目标患者特征：
Target Patient Profile:
POXET 60适用于符合早泄诊断标准的18至64岁男性患者。典型表现为阴茎在插入阴道前、插入过程中或插入后不久，在最小刺激下即发生持续或反复的射精，且对射精控制能力不佳。
POXET 60 is suitable for men aged 18 to 64 who meet the diagnostic criteria for premature ejaculation. Typical manifestations include persistent or recurrent ejaculation occurring before, during, or shortly after vaginal penetration with minimal stimulation, coupled with poor control over ejaculation。
剂量方案：
Dosage Regimen:
初始治疗：建议从性生活前1-3小时服用一片（60mg），并用足量水（至少350ml）送服。为减少潜在副作用，可考虑初始使用半片（30mg），随后根据耐受性和疗效调整至完整剂量。
Initial treatment: It is recommended to take one tablet (60mg) 1-3 hours before sexual activity with an adequate amount of water (at least 350ml). To reduce potential side effects, starting with half a tablet (30mg) can be considered, followed by adjustment to the full dose based on tolerance and efficacy。
最大用药频率：每24小时内不得超过一次服药。临床研究表明，连续使用可获得累积效果，建议至少持续使用4-8周以评估全面疗效。
Maximum dosing frequency: Should not exceed once every 24 hours. Clinical studies suggest that continuous use can provide cumulative benefits, and it is recommended to continue for at least 4-8 weeks to fully evaluate efficacy。
四、临床优势与治疗效果
4. Clinical Advantages and Therapeutic Effects
独特优势：
Unique Advantages:
- 快速起效：与传统SSRI药物需要数周才能起效不同，POXET 60在服用后约1-2小时即可发挥效果，满足按需治疗需求
- 专业靶向：专为早泄研发，针对射精控制机制具有特异性调节作用
- 安全性良好：短半衰期特性减少了药物在体内的蓄积风险
- Rapid onset: Unlike traditional SSRIs that require weeks to take effect, POXET 60 works within approximately 1-2 hours after administration, meeting on-demand treatment needs
- Specialized targeting: Specifically developed for premature ejaculation, it has a targeted regulatory effect on the ejaculation control mechanism
- Favorable safety profile: The short half-life reduces the risk of drug accumulation in the body
临床效果数据：
Clinical Efficacy Data:
研究表明，使用POXET 60可延长射精时间2-3倍，显著改善射精控制力和性满意度。在随机对照试验中，60mg剂量组相比安慰剂组显示出显著更好的疗效。
Research indicates that using POXET 60 can prolong ejaculation time by 2-3 times, significantly improving ejaculatory control and sexual satisfaction. In randomized controlled trials, the 60mg dose group showed significantly better efficacy compared to the placebo group。
五、注意事项与安全使用
5. Precautions and Safe Usage
禁忌症与慎用情况：
Contraindications and Cautions:
绝对禁忌：对达泊西汀或任何成分过敏者；严重肝损伤（Child-Pugh C级）患者；同时服用单胺氧化酶抑制剂（MAOIs）或停药后14天内。
Absolute contraindications: Hypersensitivity to Dapoxetine or any ingredient; patients with severe hepatic impairment (Child-Pugh Class C); concomitant use with monoamine oxidase inhibitors (MAOIs) or within 14 days of discontinuing MAOIs。
