They’re often used for penis rehabilitation, usually after prostate surgery. Your doctor will put you on a regimen designed to restore normal blood flow to the penis. This will allow you to get a spontaneous erection.
The pathogenesis of organic ED is related to dysfunction of the endothelium. Endothelial cells can become injured through a variety of mechanisms, most of which cause oxidative stress on the tissues. Many of these causes of oxidative stress are related to lifestyle issues which lead to hypertension, diabetes and dyslipidaemia (figure 1). Endothelial cell dysfunction results in reduction of endothelium-dependent vasorelaxation as well as increased adhesion of leukocytes to the endothelium. Endothelial cell injury then leads to a variety of sequelae, including ED, other types of vasoconstriction, atherosclerosis and thrombus formation.18 .
Sildenafil is not suitable for some people. To make sure it's safe for you, speak to your doctor or pharmacist before taking sildenafil if you:
You tried Viagra and it’s not working out for you. It’s time to talk to our providers. It’s important to discuss your results (or lack of) with our providers so we can adjust your treatment plan. We are here to help find solutions that work for you, and fortunately there are several options we can take if your sildenafil isn’t working well for your erectile dysfunction.
Sildenafil is the generic version of Viagra, the first-line medication offered by many doctors because it’s been on the market longest and its side effects and drug interactions are well known. Sildenafil works exactly as Viagra does and can cause the same side effects, including dizziness, nausea, rash, pain in the arms or legs, and abnormal vision.
The physiologic mechanism of erection of the penis involves release of nitric oxide (NO) in the corpus cavernosum during sexual stimulation. NO then activates the enzyme guanylate cyclase, which results in increased levels of cyclic guanosine monophosphate (cGMP), producing smooth muscle relaxation in the corpus cavernosum and allowing inflow of blood.
Viagra usually starts to work within 30 to 60 minutes. You’ll need to be aroused for this medicine to work.
Sildenafil enhances the effect of NO by inhibiting phosphodiesterase type 5 (PDE5), which is responsible for degradation of cGMP in the corpus cavernosum. Sildenafil has no direct relaxant effect on isolated human corpus cavernosum. When sexual stimulation causes local release of NO, inhibition of PDE5 by sildenafil causes increased levels of cGMP in the corpus cavernosum, resulting in smooth muscle relaxation and inflow of blood to the corpus cavernosum. Sildenafil at recommended doses has no effect in the absence of sexual stimulation.
Red ginseng is considered the “herbal Viagra” and is great in improving erections and increases a man’s libido. The red ginseng is got from steaming the ginseng root and then drying it. The ginseng root is the most effective part of the plant and can be taken as a supplement too. For maximum efficiency, take ginseng in dosages between 600 to 1,000mg three times a day. You’ll see your ED start to reduce.

The results from this pilot study are shown in Table 3; the mean resting systolic and diastolic blood pressures decreased by 7% and 10% compared to baseline in these patients. Mean resting values for right atrial pressure, pulmonary artery pressure, pulmonary artery occluded pressure and cardiac output decreased by 28%, 28%, 20% and 7% respectively. Even though this total dosage produced plasma sildenafil concentrations which were approximately 2 to 5 times higher than the mean maximum plasma concentrations following a single oral dose of 100 mg in healthy male volunteers, the hemodynamic response to exercise was preserved in these patients.
Unlike sildenafil or Viagra, Cialis can stay in the body for up to 36 hours and can help men become erect anytime during that window. It can be taken on demand or at a lower daily dose. Unlike Viagra or sildenafil, you can take Cialis with or without food.
Sildenafil is used to treat male sexual function problems (impotence or erectile dysfunction-ED). In combination with sexual stimulation, sildenafil works by increasing blood flow to the penis to help a man get and keep an erection.This drug does not protect against sexually transmitted diseases (such as HIV, hepatitis B, gonorrhea, syphilis). Practice "safe sex" such as using latex condoms. Consult your doctor or pharmacist for more details.
Erectile dysfunction, or being unable to maintain an erection firm enough to have sexual intercourse, affects a majority of men between the ages of 40 and 70. Appointments Request an Appointment
