Viagra and Cialis, both classified as PDE5 inhibitors, treat erectile dysfunction (ED) by improving blood flow to the penis, helping men achieve and maintain an erection during sexual arousal. The natural erection process begins with sexual arousal, which triggers the release of cyclic guanosine monophosphate (cGMP).

This chemical relaxes the muscle tissue in the penis's corpora cavernosa chambers, allowing blood to rush in and become trapped, creating a firm erection. Once arousal ends (after ejaculation), the enzyme phosphodiesterase type 5 (PDE5) breaks down cGMP, causing the erection to subside. When this process doesn't function correctly, it can lead to erectile dysfunction (ED). Sometimes, the enzyme PDE5 acts prematurely, breaking down cGMP before enough blood has flowed into the penis. Without adequate blood flow, an erection may not occur or may not be sustained. Because both medications act on the same pathway, combining them increases the likelihood of side effects.
