If erectile dysfunction is an issue for you, have you thought about Viagra? Viagra is a well-known medication that treats the symptoms of erectile dysfunction. Viagra was actually the first erectile dysfunction ever made that could be taken orally. In the decades since its creation, Viagra has been prescribed in millions of doses to millions of men around the world, and has quickly established a reputation as an effective, reliable, and convenient treatment for erectile dysfunction.

This history of being the first is reflected in the official slogan Viagra is marketed under today:

“Original brand, still the one to talk about.”

If reading this has made you interested in incorporating Viagra into your life, you may be wondering how to get it. The best way to obtain Viagra is to talk to your doctor, who can then write you a prescription you will be able to fill at a licensed pharmacy. There is no shame in having erectile dysfunction and you should not feel self conscious when talking about it with your doctor – just remember that erectile dysfunction, while annoying and unpleasant, is a totally normal condition. According to the website of Viagra’s manufacturer, 50% of men over 40 have erectile dysfunction to some degree. Viagra’s manufacturer also emphasizes that erectile dysfunction is not something you just have to accept and live with, because you can do something about it with Viagra. Viagra’s manufacturer also agrees with us that erectile dysfunction is a genuine medical condition and should be addressed like one, which is why it is important you involve a physician in determining if Viagra is right for you. While there are a number of online pharmacies claiming to be able to sell Viagra in South Africa, we do not recommend this alternative method of obtaining medication. Viagra, due to its fame, popularity, and general prominence in its market, is one of the most generic drugs in the world. generic Viagra pills have contained harmful substances like blue printer ink or even illegal drugs such as amphetamines. If you buy pills off a website, thinking they are Viagra, and then are unable to get an erection during sexual activity even though you took a pill earlier, you will regret it and wish you had not wasted your time doing things this way.

In South Africa, Viagra is regulated as a schedule four drug, which means it should only be obtained via a prescription.

Viagra is subsidized by the South African government under the Pharmaceutical Benefits Scheme and can be purchased for the reasonable price of .20 per packet. Each packet contains four tablets, which is four separate doses of Viagra. Viagra comes in dosages between 25 and 100 milligrams. To determine which dosage will work best for you, you should have a conversation with your doctor, who will be able to evaluate your medical history and lifestyle in making his or her decision.

Viagra is in, but is the temporary UP worth the DOWNS?

In the society today people are becoming more and more sexual.

For men this can be an issue when they start to experience issues with their vital sexual organ. The main condition in reference here is erectile dysfunction. Erectile dysfunction arise for various reasons in men which consequently disables them from being able to obtain an erection. Some of the haunting reasons are age and stagnant to declining physical health. Obtaining an erection is usually achieved when a man is sexually stimulated. The physiological depiction of an erection is a rush of blood flow traveling to the penis when a man is aroused. This action is missing when men suffer from erectile dysfunction. Erectile dysfunction drastically decreases the blood flow that leads to the penis. This is mainly due to the pressure that is on the blood vessels caused by underlining issues which causes the blood flow to be noticeably restricted.

The online community has opened up a new way of handling medical condition.

In this century we are seeing more men turning to electronic sources to find resolutions to problems like erectile dysfunction. Australia has a large market for allowing access to drugs on the open market that would normally require a prescription. The channel that are often used by Australian companies are online pharmacies. These online line pharmacies offer convenient and cheap access to drugs, all while maintaining one’s privacy. Online pharmaceutical companies will ship drugs to men wherever they would like as soon as seven days from the time of purchase. There is no limit of the quantity of the drug as online pharmacies are not regulated. It is even encouraged that more pills are purchased at one time for cheaper prices and better deals. One drug that is an oldie but goodie that men are flocking to these online pharmacies purchase is Viagra.

Viagra is a drug that acts on the constricting blood vessels in the pelvic area which allows for blood to freely flow into the pelvic area.

Even though the access to Viagra is readily available with the online pharmacies, it is strongly advices that men obtain the advice from a medical professional prior to taking the drug. There are common side effects associated with taking Viagra can be intense, but Viagra mixed with the wrong medications may cause a fatality. The drug is normally prescribed in dosages of one tablet within a given 24 hour period. The drug acts fast and increasing the dosage will not increase the intensity of the drug’s effects. Taking more of the drug will result in a more intense experience of the side effects.

Men who tend to buy Viagra and other regulated drugs online through these pharmacies must not be naïve in their purchase.

Research is required before trusting a site to send the drug that it claims to have, especially with Viagra. Viagra is a drug that has a very easy composition and many online pharmacies have been caught sending men drugs that look and seem very similar to the real drug but lacking either the active ingredient or containing too much of the active ingredient; which as stated above could be observed having an increased negative expression of the side effects.

Viagra: The Natural Male Enhancement to remedy erectile dysfunction

Viagra pills for men

What would you do if I told you that erectile dysfunction is not a matter of if but when? Would you start taking steps to protect yourself from one of the fastest growing conditions that men face today? You might say yes.

However, the truth of the matter is that most men will not. This year experts estimate of ten million or more men will be diagnosed with erection problems. Almost three million of those men are going to be coming from Australia alone. Today we are going to cover the many reasons men seem to be blatantly ignoring their sexual health. In addition to that, we will be going over a popular medication known as Viagra and how it will help you.

So what’s the deal? Why are so many men seemingly ignoring the very real threat of erectile dysfunction?

The short answer is we aren’t. Well not completely. Erectile dysfunction and its dangers are something that just isn’t spoken about through normal channels. Information like this has to be searched for. Just like you searched for this article. This is the kind of information you just won’t find on television or mainstream media platforms. When it comes to women’s health and issues, most guys are bombarded but with men’s problems, they rarely hear about it. Guys can’t be warned about their sexual health if the major sources aren’t spreading the word.

For the minority of men that are well aware of the dangers of erectile problems, the reason they ignore their problems is a little more complicated.

Currently, there are millions of men living in Australia with erectile problems and less than a quarter of those men seek help. A recent poll revealed that these men aren’t seeking treatment for two reasons. The first being cost and embarrassment. Let’s be honest here for a second. We all know the last thing that any man wants to deal with is erectile dysfunction. Let alone have to speak to others about that problem.

When it comes to cost, I completely agree. Erectile dysfunction treatments like Viagra are not covered by medical insurance.

Of course, I think this is a major flaw in the medical field. However, some insurance companies are starting to recognize the serious health problems that erectile dysfunction can cause if left unchecked. More about that later but first let me show you a way to get Viagra up to 50% off. Are you ready? Shop online. Yup, that’s all you need to do. Make sure you shop for Viagra online instead of in a physical store. The prices in stores are marked up so high that I would consider it highway robbery.

Before you start shopping you need to speak with a doctor and get the “OK” to use Viagra.

This is going to require a consultation with a general practitioner or a cardiologist. If you want to avoid any real intimate talks with the doctor about your erections. Then your best bet would be talking with a cardiologist. They can run the proper test and know what is going on without you mentioning erectile issues. When they start talking about treatment options make sure you bring up Viagra. It has a high success rate among all forms of erectile issues. If you haven’t already, schedule an appointment with your doctor today and as about Viagra.

Viagra: ask your pharmacist

Sildenafil, sold as the brand name Viagra among others, is a medication used to treat erectile dysfunction and pulmonary arterial hypertension.It is unclear if it is effective for treating sexual dysfunction in women. It is taken by mouth or injection into a vein. Onset is typically within 20 minutes and lasts for about 2 hours

Common side effects include headaches, heartburn, and flushed skin.Caution is advised in those with cardiovascular disease. Rare but serious side effects include a prolonged erection that can lead to damage to the penis, vision problems, and hearing loss. Sildenafil should not be taken by people on nitrates such as nitroglycerin (glycerin trinitrate), as this may result in a serious drop in blood pressure.

Sildenafil acts by blocking phosphodiesterase 5 (PDE5), an enzyme that promotes breakdown of cGMP, which regulates blood flow in the penis. It requires sexual arousal, however, to work.It also results in dilation of the blood vessels in the lungs.

Pfizer originally discovered the medication in 1989 while looking for a treatment for heart related chest pain. It was approved for medical use in the United States and Europe in 1998.In the United States about 2 million prescriptions were written for sildenafil in 2016. In 2017 it became available as a generic medication.In the United Kingdom it is available over the counter. As of 2018 in the United States the wholesale cost is less than US per dose. Sildenafil protects cyclic guanosine monophosphate (cGMP) from degradation by cGMP-specific phosphodiesterase type 5 (PDE5) in the corpus cavernosum. Nitric oxide (NO) in the corpus cavernosum of the penis binds to guanylate cyclase receptors, which results in increased levels of cGMP, leading to smooth muscle relaxation (vasodilation) of the intimal cushions of the helicine arteries. This smooth muscle relaxation leads to vasodilation and increased inflow of blood into the spongy tissue of the penis, causing an erection.[39] Robert F. Furchgott, Ferid Murad, and Louis Ignarro won the Nobel Prize in Physiology or Medicine in 1998 for their independent study of the metabolic pathway of nitric oxide in smooth muscle vasodilation.

Sildenafil is a potent and selective inhibitor of cGMP-specific phosphodiesterase type 5 (PDE5), which is responsible for degradation of cGMP in the corpus cavernosum. The molecular structure of sildenafil is similar to that of cGMP and acts as a competitive binding agent of PDE5 in the corpus cavernosum, resulting in more cGMP and better erections.[39] Without sexual stimulation, and therefore lack of activation of the NO/cGMP system, sildenafil should not cause an erection. Other drugs that operate by the same mechanism include tadalafil (Cialis) and vardenafil (Levitra).

Sildenafil is broken down in the liver by hepatic metabolism using cytochrome p450 enzymes, mainly CYP450 3A4(major route), but also by CYP2C9 (minor route) hepatic isoenzymes. The major product of metabolisation by these enzymes is N-desmethylated sildenafil, which is metabolised further. This metabolite also has an affinity for the PDE receptors, about 40% of that of sildenafil. Thus, the metabolite is responsible for about 20% of sildenafil’s action. Sildenafil is excreted as metabolites predominantly in the feces (about 80% of administered oral dose) and to a lesser extent in the urine (around 13% of the administered oral dose). If taken with a high-fat meal, absorption is reduced; the time taken to reach the maximum plasma concentration increases by around one hour, and the maximum concentration itself is decreased by nearly one-third.
