Sildenafil generic is a very popular medicine when it comes to the problem of men’s erectile dysfunction. Sildenafil generic is also used as a treatment drug for men who suffer from pulmonary arterial hypertension. Sildenafil generic was originally developed in Great Britain by medical scientists and then sildenafil generic was distributed in the United States by Pfizer, a well-known pharmaceutical company. The chemical makeup of sildenafil generic is C22H30N6O4S.
Sildenafil generic works mainly by stopping or inhibiting a specific enzyme called cGMP-specific PDE5 (phosphodiesterase type 5). This PDE5 slows down the degradation of the enzyme cGMP, which is actually responsible for controlling the flow of blood in a man’s penile shaft. Sildenafil generic had been first distributed in the year 1998 and since then, sildenafil generic has become the primary treatment for male impotence or erectile dysfunction. Aside from sildenafil generic, you can also check out other PDE5 inhibitors such as vardenafil, avanafil and tadalafil. Sildenafil generic is highly popular because it is the first ever treatment drug for erectile dysfunction-related problems.
For those wanting to treat their erectile dysfunction problem, sildenafil generic can be bought in the market (pharmacy, in mall drugstores, etc) as diamond-shaped blue pills. Sildenafil generic is available in dosages of 100, 50 or 25 mg. A patient who has erectile dysfunction is recommended to take a maximum of 1 pill within a 24-hour timeframe. Sildenafil generic has to be taken between 30 minutes to 1 hour prior to engaging in sexual activity. Make sure that you get the sildenafil generic that is intended for erectile dysfunction, because there is another type of sildenafil generic that is intended for pulmonary arterial hypertension.
Some men who take sildenafil generic can probably suffer from common yet minor side effects which include: nasal congestion, photophobia, dyspepsia, impaired vision and headaches. Rare side effects may include cyanopsia, or the impaired vision of a person who sees a tinge of blue in everything. Make sure that you immediately stop the medicine and go to your doctor if you experience any of these adverse side effects: sudden hearing loss, heart attack, increased pressure in the intraocular area, ventricular arrhythmia and priapism (unusually prolonged penile erection lasting for 4 hours or more). Because sildenafil generic can significantly lower one’s blood supply to the optic nerve, it can potentially cause one to experience a sudden loss of vision. This is actually a very rare side effect that can most likely happen to patients who already have hypertension, heart disease, diabetes, pre-existing eye issues or very high cholesterol. It is not certain that sildenafil generic is the real culprit contributing to the vision loss.
