We offer sildenafil for sale as Viagra SP (SP Agra) 100 mg 20 tablets. SP Agra is SP Laboratory's sildenafil tablet, 100 mg each, 20 to a pack. Sildenafil is a phosphodiesterase type 5 inhibitor, the mechanism behind the Viagra name, and the association refers to the drug class rather than to the originator's finished medicine. What is being sold here is the SP product.
The pathway runs through nitric oxide. Sexual stimulation releases nitric oxide in the corpus cavernosum, which raises cyclic GMP and relaxes the smooth muscle of the vessels supplying the penis, so blood flow increases. PDE5 is the enzyme that breaks cyclic GMP down again, and inhibiting it prolongs the signal that is already there. Because the drug amplifies a signal rather than creating one, its effect is tied to stimulation; it is not an aphrodisiac and it does not increase desire or testosterone.
The same enzyme appears in vascular tissue elsewhere, which is why blood-pressure effects are central to sildenafil's profile. Official labelling contraindicates combining it with nitrates, because the two together can drop blood pressure to a dangerous level. Other interactions are documented as well, and the prescriber's instructions belong with the product.
Sildenafil is selective for PDE5 but not exclusive to it. The phosphodiesterase family includes PDE6 in the retina, and activity at that site is associated with the blue-tinged vision that appears among the documented undesirable effects. Selectivity, in other words, is a matter of degree.
