What are the ingredients of Viagra?

Generally speaking, Viagra refers to sildenafil citrate tablets. The main component of sildenafil citrate tablets is sildenafil citrate, while the auxiliary components include magnesium hydroxide, microcrystalline cellulose, protonated hydroxypropyl cellulose, and anhydrous sodium sulfite, among others. A detailed explanation is as follows:

The primary component of sildenafil citrate tablets is sildenafil citrate. Sildenafil citrate is a selective inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5). Its mechanism of action primarily involves inhibiting PDE5 during sexual stimulation, thereby reducing the degradation of cGMP. This leads to the accumulation of cGMP in the corpus cavernosum of the penis, promoting relaxation of the smooth muscle within the corpus cavernosum, increasing blood flow into the corpus cavernosum, and subsequently inducing an erection.

In addition to the active ingredient, sildenafil citrate tablets also contain several excipients, such as magnesium hydroxide, microcrystalline cellulose, protonated hydroxypropyl cellulose, and anhydrous sodium sulfite. These excipients mainly serve to enhance the stability and palatability of the medication, ensuring it can function more effectively within the human body.

Sildenafil citrate tablets are a medication used for treating erectile dysfunction. Its formulation is scientifically proportioned to ensure both efficacy and safety. However, specific medication use should be determined according to the patient's health condition and based on a physician's advice.
