Do you know? A magical effect of Viagra was discovered in these people!
In the 1980s, the initial development goal of sildenafil was to use Viagra to inhibit an enzyme called phosphodiesterase 5 (PDE5) in the human body. cGMP can relax the cardiovascular system, increase blood flow, and effectively reduce the occurrence of diseases such as angina.
On the way of R&D, the R&D personnel found an interesting phenomenon: a group of male patients in their forties and fifties with diabetes took sildenafil citrate, but they had a special preference for this test drug and kept asking the test doctor for it after taking sildenafil citrate without effectively improving their hypertension. The secret is that while suffering from hypertension, they also develop ED symptoms. After eating the compound being tested, these people miraculously improved their sexual dysfunction.
