Sildenafil (Generic Viagra)

Sildenafil, which is a generic drug that is also known as Viagra, is a phosphodiesterase type 5 blocker that helps men with erectile dysfunction improve their sexual functioning. Sildenafil or Generic Viagra works exactly and precisely in the same way as Viagra because it is the same chemical substance, but it is significantly cheaper in Australia.

PDE-5 inhibitors

The drug is incorporated in the category of medications that are used to treat ED in men, which is called PDE5 inhibitors, and it also includes drugs like Tadalafil, Vardenafil or Avanafil. Sildenafil, however, is the most prominent and frequently prescribed medication for erectile dysfunction. It is also sometimes used to treat pulmonary hypertension because of its capacity to induce a beneficial dilation of blood vessels in the lungs, which relieves the bothersome symptoms of the disease.

Viagra for women

Several research studies indicate that Viagra may also be useful in women because it enables an increased blood flow in the pelvic region, which is very useful in cases when sexual arousal is difficult in women.

How does Sildenafil work to induce the beneficial changes that result in an improved erection in men?

Sexual stimulation is followed by a signal transmitted from the brain to the penis, which results in the release of nitric oxide (NO) as a messenger substance that acts on certain enzymes. The activated enzyme is producing cyclic GMP, which is precisely the molecule that interacts with the complex network of blood vessels in the cavernous structures of the penis. These specialized structures have the ability to dilate strongly after sexual stimulation and receive huge quantities of blood, which is an erectile response. Cyclic GMP influences these blood vessels to dilate, which results in an adequate erection and a normal sexual intercourse. However, cGMP life is short because the PDE5 enzyme destroys it rapidly. In some men, the cGMP insufficiency may cause erectile problems, which can be addressed through Sildenafil administration. Sildenafil blocks the PDE5 enzyme in the cavernous bodies of the penis, which means that enough cyclic GMP can accumulate and exert the dilation effect on the blood vessels. After Sildenafil administration, the ability to achieve a high-quality erectile response is restored for two to three hours.

Side effects

It is wise to talk to your doctor prior to initiating treatment with Sildenafil if you have other medical conditions that are require medication. Sildenafil has very few side effects, most of which are temporary. Examples may be nausea, abdominal discomfort, headaches or congestion of the nose, also known as a stuffy nose. If you experience more severe adverse effects, don’t hesitate to notify your physician. Take Sildenafil as prescribed by your doctor and try not to exceed the recommended dosage to enjoy the full benefits of the treatment.
