Sildenafil, which is found in Cenforce 100 tablets, belongs to a class of drugs known as Phosphodiesterase type 5 (PDE5) inhibitors.
Sildenafil Citrate inhibits PDE5 enzymes, increasing the effects of Nitric Oxide.
This increase in cGMP in smooth muscle cells is responsible for extending an erection by dilatation of blood vessels and increased blood flow to the penile area.
As a result of this mechanism, blood flow in the penis increases, making it easier for men to obtain an erection during sexual intercourse.
Cenforce 200 and Cenforce 150 mg does not have an immediate effect on smooth muscle relaxation. As a result, adequate sexual stimulation is required to achieve an erection during sexual intercourse.
