What Is Erectile Dysfunction?

Even though many think 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 participating. If a problem with these organs and physiological responses occur, then a problem with erections may develop.

Erections will naturally take longer to form and may not be as firm as you get older. 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 was created and synthesized by a group of chemists in a research facility in England. Researchers created Sildenafil Citrate to observe its reaction to hypertension, angina pectoris, and 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 erectile dysfunction. The ED drug was patented in 1996 and approved for erectile dysfunction by the FDA in March 1998. Viagra was the first oral treatment approved for es erectile dysfunction at its time. At its peak, the annual sales of VIAGRA topped $1.934 billion.

How Does Greenstone Sildenafil Citrate Work?

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

Viagra relaxes the muscles, allowing better blood flow to dilate the shaft properly. 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 beneficial in most scenarios.

Is Greenstone Sildenafil Citrate an Authorized Generic of Viagra?

Yes, Greenstone Sildenafil Citrate is the only authorized generic drug of Viagra and is an exact copy of an original brand-name drug marketed under the private label.

An Authorized product is usually the brand companys drug repackaged and sold through a subsidiary or another third party.

In other words, it is a brand-name drug with the same active ingredient, route of administration, and therapeutically equivalent to the brand companys drug even though the product does not have the brand name on its name label.

It is common in the industry to market and distribute the authorized generic drug through an approved private company with permission from the brand.

The authorized generic drug may be identical in color, strength, size, administration routine, dosage form, and active and inactive ingredients to the original brand-name drug.

Benefits of Purchasing a Greenstone Authorized Generic

Insurance companies and healthcare providers both recognize an authorized generic drug is an exact copy of the brand name drug.

An Authorized generic is also medication manufactured by a private company other than the company that developed and made the brand-name drug.

In other words, both the authorized generic and brand drug developed from the same manufacturing line. The original manufacturer usually packages under the brand name while marketing the private label at the generic price.
