Fortunately
, Jim was referred to a GP who placed him on Viagra.
As a result, Jim is able to step up his performance and shelve any idea of divorce.
Jim's story may be familiar to a number of people. This is because erectile dysfunction is a condition which affects a great number of men in today's population.
However, there are a number of drugs to help manage the condition.
An example is Viagra.

Viagra is the trade name of the drug Sildenafil.
It works by causing muscle relaxation and increasing blood flow to the penis.
Thereby improving and sustaining erection.
However, it does not improve libido which is the sex drive.

It is essential to note that while taking sildenafil, you are not expected to take in addition other nitrate containing drugs like nitro glycerine.
This is because a combination of the two drugs can cause a cascading decrease in blood pressure which is usually fatal.
This has been a leading cause of death among men taking antihypertensive medication.
Also the stimulating drug "poppers" should be avoided because it contains nitrate.
In addition if you experience extended periods of sustained erection over a period of four hours, (priaprism) while taking sildenafil, it is essential that you stop the medication and consult your healthcare provider.
In conclusion, erectile dysfunction is a condition that can be managed with effective therapy and proper management.
