When it comes to treating erectile dysfunction (ED), generic Viagra is a top alternative, and XLPharmacy the best choice for Viagra Online without prescription. This medication is made with Sildenafil Citrate, which the most well known treatment for ED, albeit not the only one. Similar chemicals, known as PDE5 inhibitors, include Tadalafil, used to manufacture Cialis, and Vardenafil, employed to make Levitra. As it turns out, Cialis without prescription is available as well at XL Pharmacy, as is Levitra. Though customers may buy these with no prior medical prescription, they should be aware that no online medical consultation can ever take the place of their local doctors.
Having cleared up this aspect of Viagra without prescription, it is also of importance to know how this medication works. Sildenafil Citrate is effective against erectile dysfunction because it inhibits an enzyme called PDE5. This enzyme is normally found in the muscle tissue of the penile region, but when there is an excess of it, it may block the blood vessels, leading to a shortage in the blood supply to this sexual organ. Sildenafil attaches to PDE5 and counteracts its action, and by doing so, it paves the way for blood to reach the penis. Once this happens, this organ is fully functional and will be able to produce an erection as a result of arousal.
Since generic for Viagra medications are made with this same active ingredient, they work just as well as brand name drugs, with the added benefit of cheap prices, and discounts and offers exclusive of XLPharmacy. This is also true for Cialis without prescription.
