1. What is generic Viagra?

- Generic versions of Viagra (sildenafil citrate) are drugs that contain the same active ingredient as the brand - name Viagra. They are produced after the patent of the original drug has expired.

- These generics are designed to work in a similar way to the brand - name product, which is mainly used to treat erectile dysfunction (ED) in men. By inhibiting the enzyme phosphodiesterase - 5 (PDE - 5), it helps increase blood flow to the penis, enabling an erection when sexual stimulation occurs.

2. Considerations when using generic Viagra

Viagra generico refers to generic Viagra.

- Quality and safety:

- In many countries, generic drugs are required to meet strict regulatory standards for quality, efficacy, and safety. However, it is important to ensure that the source of the generic Viagra is from a legitimate and regulated manufacturer.

- Cost:

- One of the main advantages of generic Viagra is that it is often more affordable than the brand - name version. This can make treatment for ED more accessible to a larger number of patients.

It is crucial that any use of Viagra, whether brand - name or generic, is done under the guidance of a healthcare professional, as there may be potential side effects and contraindications.


Viagra generico 是指通用版本的伟哥,即西地那非(Sildenafil)的非专利版本,这种药物主要用于治疗男性勃起功能障碍(ED),通过增加阴茎血流来帮助实现和维持勃起。

1、作用机制:西地那非属于5型磷酸二酯酶抑制剂(PDE5抑制剂),它通过抑制PDE5酶的作用,阻止cGMP的降解,从而促进阴茎海绵体平滑肌松弛,增加血液流入,达到增强勃起的效果。

2、使用方法:通常在性生活前30分钟至1小时口服,剂量根据个人情况调整,常见起始剂量为50mg,可根据需要和耐受性增加到100mg或减少到25mg。

3、注意事项

- 在使用前应咨询医生,尤其是有心脏病、高血压、糖尿病、视网膜问题等基础疾病的患者。

- 避免与硝酸盐类药物(如用于心绞痛的药物)同时使用,因为这可能导致严重的血压下降。

- 可能的副作用包括头痛、潮红、消化不良、视觉异常等,严重副作用较少但需警惕,如持续的视力变化或听力损失。

- 饮酒可能会影响药效,建议用药期间限制酒精摄入。

4、购买建议:由于涉及健康风险,购买时应选择正规渠道,确保药品质量和安全性,在一些国家和地区,可能需要医生处方才能购买。

虽然Viagra generico是治疗ED的有效药物,但正确使用并遵循医嘱至关重要。
