Usage of sildenafil:

Because Sildenafil Citrate/Viagra is a selective inhibitor of phosphodiesterase (PDE) V, it can enhance the physiological response of penile erection under sexual stimulation, so it is mainly used for male erectile dysfunction.

What are the pharmacological effects of Sildenafil Citrate?

Sildenafil Citrate/Viagra is an oral medicine for the treatment of erectile dysfunction (ED). It is also translated as sildenafil. It is a drug for the treatment of male erectile dysfunction accidentally invented during the development of drugs for the treatment of cardiovascular diseases. Mechanism of action: The physiological mechanism of penile erection involves the release of nitric oxide (NO) from the penis cavernous body during sexual stimulation. NO activates guanylate cyclase to increase the level of cyclic guanosine phosphate (cGMP), which relaxes the smooth muscles in the cavernous body and fills the blood.

The Dosage for sildenafil citrate:

1. Under normal circumstances, we recommend that the dosage of Sildenafil Citrate/Viagra is 50mg, when should it be taken? It should be taken about 1 hour before sexual activity. Even after taking the medicine, sexual stimulation is still needed to exert its effect. If the range is wider, it can be taken within 0.5 to 4 hours before sexual activity. Taking into account the efficacy and human tolerance, the daily dosage should be adjusted between 25mg-100mg, but sildenafil should not be used more than once a day. (1) In case of renal insufficiency, we recommend a starting dose of 25mg per day. (2) If the liver function is insufficiency, such as liver cirrhosis, the dosage should also be 25mg.

2. General doctors suggest that for the elderly over 65, the dosage should also be 25mg.
