try generic viagra online. Men with erectile dysfunction are prescribed Viagra, which is a member of the group of drugs known as phosphodiesterase type 5 (PDE 5) inhibitors. Men who are sexually stimulated experience a blood engorgement in the penis, which results in an erection. Nitric oxide is released as a result, and cyclic guanosine monophosphate (cGMP), a compound that regulates blood vessel size, is also activated. Sildenafil citrate, the active component of Viagra, prevents cGMP from being destroyed, allowing for increased blood flow to the penis and the onset and maintenance of an erection. Nitric oxide is a crucial element in achieving and sustaining an erection, hence Viagra is useless without sexual stimulation. Approximately 30 to 60 minutes before sexual activity, one takes Viagra orally.
