Fildena 100 mg is used to treat erectile dysfunction in males. Viagra belongs to the family of medications known as phosphodiesterase-5 (PDE-5) inhibitors. These drugs prevent phosphodiesterase type-5 from working too quickly. The urethra is one of the locations where this enzyme is active.
If a guy becomes sexually aroused or has difficulty maintaining an erection, he may have erectile dysfunction, which means his penis does not stiffen and become larger.When a guy is sexually excited, his body sends more blood to his penis, resulting in an erection. After the penis has been massaged, Viagra aids in the maintenance of an erection. This is accomplished by regulating an enzyme. Viagra will not work to generate an erection unless there is physical motion to the penis, such as during sexual intercourse.
