Viagra is a phosphodiesterase type 5 (PDE 5) inhibitor that is prescribed to males suffering from erectile dysfunction. When males are sexually stimulated, the penis fills with blood, causing an erection. This results in the release of nitric oxide and the activation of cyclic guanosine monophosphate (cGMP), a chemical involved in modulating blood vessel size. try generic viagra online
The active ingredient of Viagra, sildenafil citrate, prevents the degradation of cGMP, resulting in increased blood flow to the penis and the attainment and maintenance of an erection. Viagra is ineffective without sexual stimulation because nitric oxide is required for developing and sustaining an erection. Orally, Viagra is taken 30 to 60 minutes before sexual activity.
