Medications such as Cialis and Viagra work by preventing PDE5 inhibitors from working. This allows cGMP to remain in the muscle for a longer period, resulting in more erection time. While many people believe these medications actually cause an erection, they don t. These medications, instead, interfere with a chemical reaction which prevents the erection from happening. Those using medications such as Viagra and Cialis are able to achieve erections and maintain them for longer periods, improving their overall erection strength and time without the need for surgery or assistive devices.
