What Is Erectile Dysfunction?

Erectile dysfunction defined as the difficulty of maintaining an erection for any given amount of time, where the poor performance starts to affect your sexual, physical, and emotional life. There are many severe causes of erectile dysfunction, including illness, inadequate blood flow to the penis to sustain its rigidity, the frequent consumption of alcohol, and other suppressants.

Erectile dysfunction can also indicate poor emotional health within a relationship. Sildenafil Citrate works by allowing your body to overcome these factors, providing a drastically improved sex life.

Interestingly enough, Sildenafil Citrate can also help in other areas of your life, including premature ejaculation or lack of interest in sharing a sexual experience with your partner. Not only can erectile dysfunction help you feel more confident in yourself, but it will make your life easier and allow you to be more satisfied with your partner and any person that you are sharing sex.

What Causes Erectile Dysfunction?

Even though many think that it is a relatively straightforward process, sexual arousal for men is quite complicated. It involves hormones that trigger a physical reaction, with emotions, blood vessels, and the brain all having a part in the process. If a problem with any of these organs and physiological responses occur, then a problem with erections may develop.

As you get older, erections will naturally take longer to form and may not be as firm. You may need direct touch for an erection to occur, with emotions and visual aids not being enough.

Several risk factors can also contribute to the issue of erectile dysfunction.

Medical conditions like diabetes that dilate blood vessels, the use of tobacco that can restrict blood flow to the arteries and veins, being overweight, radiation treatment, certain antidepressants, and antihistamines designed to treat high blood pressure, and anxiety to perform well.

Common causes include:

  1. Heart problems
  2. Alcoholism
  3. High cholesterol
  4. Clogged blood vessels
  5. Poor communication in your relationship

Generic Viagra Erectile Dysfunction Medication

Viagra initially synthesized by a group of chemists in a research facility in England Sildenafil Citrate was first used to observe its reaction with hypertension and angina pectoris, a form of ischemic heart disease.

Sildenafil Citrate, the active ingredient in the medication, had minimal impact on angina, but it had induced erectile erections in test subjects. Instead of marketing it as a medication to help alleviate heart problems, Pfizers Sandwich decided to sell it to help aid with erectile dysfunction. The drug was patented in 1996 and approved for erectile dysfunction by the FDA in March 1998. It was the first oral treatment approved for es an erectile dysfunction at its time. At its peak, the annual sales of VIAGRA topped at $1.934 billion.

How Does Greenstone Sildenafil Citrate Works?

Sildenafil Citrate works as a PDE5 inhibitor. PDEF5 medications interact with the action of cGMP-specific phosphodiesterase type 5 on cyclic GMP in the smooth muscle cells in the penis.

It will then relax the muscles, allowing better blood flow to help properly dilate the shaft. Once the medication enters the bloodstream, it spreads directly into the circulatory system and the bloodstream, targeting and disabling the PDEF5 enzyme.

Once disabled, blood flow is relaxed, and the penis can achieve erection upon sexual stimuli. It is a well-documented phenomenon, with Sildenafil Citrate being very useful in most scenarios.

If you are also taking an alpha blocker medication (such as doxazosin, tamsulosin) to treat an enlarged prostate/BPH or high blood pressure, your blood pressure may get too low which can lead to dizziness or fainting.
