Several oral medications are available for treating erectile dysfunction (the inability to get or keep an erection). The four most common are '''sildenafil '''('''Viagra'''), '''tadalafil '''('''Cialis'''), '''avanafil '''('''Stendra'''), and '''vardenafil '''('''Levitra'''). These medications all improve blood flow to the penis when combined with sexual stimulation and are collectively known as '''phosphodiesterase 5 (PDE5) inhibitors'''. PDE5 inhibitors do not cause erections without sexual arousal, and do not increase arousal. | Several oral medications are available for treating erectile dysfunction (the inability to get or keep an erection).
