Types of Erectile Dysfunction Medications

Erectile dysfunction, also known as impotence, is a disorder that causes a dysfunction of the male reproductive system.  A man who has this condition may experience an inability to achieve or sustain an erection.  There are three commonly prescribed treatments for men with erectile dysfunction.  Each type of medication works by increasing blood flow to the penis; this can cause an ability to achieve an erection.

Genuine Viagra was the first prescribed medication for the treatment of impotence.  It may be taken 30 minutes to four hours prior to sexual activity.  Side effects may include headaches, flushing, diarrhoea and muscle aches.  Severe side effects, that require medical attention, include an allergic reaction, a painful erection that lasts longer than four hours and changes in vision or hearing.  To buy Viagra online, men must first obtain a prescription from their health care professional.

Another commonly prescribed treatment for impotence is genuine Levitra.  Levitra may be prescribed under the generic name Vardenafil.  Levitra is taken approximately one hour before sexual activity.  Side effects may include upset stomach, congestion or flu-like symptoms.  Other side effects that require medical attention include an allergic reaction, loss of hearing or blurred vision.

Cialis is proven to be effective for up to 36 hours, so it may be taken a day prior to sexual activity.  Side effects include heartburn, muscle aches and nausea.  Any signs of an allergic reaction, loss of vision or hearing and chest pain require immediate medical attention.  To get Cialis online or buy other medications used in the treatment of impotence, men should obtain a prescription from their health care professional.  

Heart Failure and Viagra

Sildenafil citrate is used as a first-line drug for erectile dysfunction. Many men have benefited from the use of this medication. Although its primary use is for male sexual problems, it is now showing promise in the treatment of heart disease. According to researchers at the University of Alberta, it is a potential treatment for patients with right ventricular failure, a type of heart failure.

With right ventricular failure, the right ventricle becomes unable to pump blood. This leads to a backflow to the right atrium and to the inferior vena cava and superior vena cava. When this occurs, the blood vessels become congested and insufficient blood supply reaches the organs of the body. `

Sildenafil (Viagra) is a phosphodiesterase-5 inhibitor. Phosphodiesterase-5 is an enzyme responsible for constriction of arteries in the lungs and in the penis. However, excessive amounts of phosphodiesterase-5 can excessively constrict the blood vessels.

When the pulmonary capillaries and arteries are excessively constricted, pulmonary hypertension results. Pulmonary hypertension overloads the right ventricle, leading to or aggravating right ventricular failure. By using a phosphodiesterase-5 inhibitor like Viagra, the pulmonary arteries relax, leading to a reduction of the strain on the right ventricle.

In addition, it has been found out that phosphodiesterase-5 is present in excessive amounts in thickened or hypertrophied right ventricles. This is not observed in normal healthy hearts. When Viagra is used on animal models, it increases the output of these thickened right ventricles. This effect of sildenafil is believed to be of great benefit to heart failure patients in the future.

Sildenafil as Treatment for Impotence

The ability to obtain and sustain an erection is one of the hallmarks of masculinity. However, it is quite common among men to encounter difficulty in this area. Causes of impotence, erectile dysfunction or ED can be classified as psychogenic or organic.

When the cause is psychogenic, the erectile dysfunction is sudden, associated with a partner problem or with anxiety or fear of poor performance. When the cause is organic, the onset is gradual, and partner problems are encountered later on. Whereas psychogenic problems may be addressed by a psychiatrist, organic problems are usually solved by the intake of ED drugs such as sildenafil or Viagra.

Viagra belongs to the drug classification of phosphodiesterase-5 (PDE-5) inhibitors. PDE-5 is an important enzyme that degrades the molecule called cGMP. When the concentration of this molecule in the penile muscle is elevated, the penile muscle relaxes, allowing the inflow of blood, which results to an erection. Because PDE-5 breaks down cGMP, it prevents erection or decreases its quality and duration. By opposing the action of PDE-5, sildenafil facilitates the elevation of cGMP levels, leading to a better and longer erection.

Sildenafil or Viagra is available in different formulations. One can buy Viagra online in 25 mg, 50 mg and 100 mg tablets. Its effect becomes apparent 1 hour after intake and can last up to 6 hours. To buy Viagra online and ensure its effectiveness, it is best to consult a doctor first. Men who are taking maintenance medications like nitro-glycerine for angina have to avoid it because it causes hypotension and rarely, heart attack or myocardial infarction.

Viagra for Erectile Dysfunction

Erectile dysfunction is a common problem among men. Studies show that erection involves relaxation of the penis muscle called corpora cavernosa. As the corpora cavernosa relaxes, blood is able to flow from the nearby arteries into the sinues or spaces of the cavernosa. The blood pressure resulting from this inflow is the main cause of erection. However, among men who have poor blood flow or a defect in the relaxation of the muscle, erectile dysfunction becomes a problem.

Viagra or Sildenafil is a drug designed to address problems in the relaxation of the corpora cavernosa. Normally, before the corpora cavernosa can relax, a substance called nitric oxide has to be released from the parasympathetic nervous system first. Nitric oxide activates an intracellular enzyme called guanylyl cyclase, which, in turn, increases the concentration of a molecule called cyclic guanine monophosphate or cGMP.

With increased concentrations of cGMP, the smooth muscle relaxes and blood is able to flow into the penis, resulting into an erection. Viagra is able to address erectile dysfunction by increasing the concentrations of cGMP through the inhibition of an enzyme called phosphodiesterase-5 (PDE-5). Visual stimulation is needed for this drug to take effect, which means it only works as needed.

Viagra is widely accepted because it can be taken orally and its effect lasts for about 6 hours. It is available in 25 mg, 50 mg, and 100 mg tablets. A relatively mild side effect is headache. However, men who are already taking nitrates such as isosorbide nitrate and nitro-glycerine have to avoid this drug because it can cause a severe drop in blood pressure or hypotension. 

Erectile Dysfunction: Causes and Oral Treatment

Erectile dysfunction (ED) or impotence is a common problem among men. Although it is not considered a normal part of aging, it occurs in association with psychological and physical changes related to increasing age. It is more common among men who have medical disorders such as obesity, diabetes mellitus, hypertension, benign prostatic hyperplasia (BPH), heart disease and decreased high-density lipoprotein (HDL) levels. Other risk factors for erectile dysfunction include drugs used to treat cardiovascular diseases and diabetes and smoking. Approximately 80% of ED cases in older men are attributable to diabetic, atherosclerotic and drug causes.

As such, the mechanisms of how ED comes about can be classified into three types. The first is the failure to initiate erection, which is usually due to psychologic, endocrinologic and neurogenic causes. The second is called “arteriogenic” in reference to the failure to fill the penile smooth muscle with blood. The third is called “veno-occlusive dysfunction” because there is failure to store sufficient blood volume, which in turn leads to inability to maintain erection.

The three FDA-approved oral agents for the treatment of ED are sildenafil (Viagra), tadalafil and vardenafil. They can be used to manage ED secondary to psychogenic, vasculogenic and diabetic causes. They are also effective for men who have had postradical prostatectomy and spinal cord injury.

Viagra, tadalafil and vardenafil are all phosphodiesterase-5 (PDE-5) inhibitors. Their onset of action ranges from 60 to 120 minutes. Their side effects include headaches, facial flushing, dyspepsia, nasal congestion and altered colour vision. Men who are elderly, taking alpha blockers or have renal problems have to take reduced doses to avoid toxicity.

How Viagra Treats Erectile Dysfunction

One of the serious problems for men in the 21st century is erectile dysfunction or impotence. From an age-adjusted prevalence of 152 million in 1995, it is estimated that as many as 322 million males will be suffering from this problem by 2025. Despite these estimates, it is believed that only 8% actually seek medical help and are diagnosed. However, men who suspect themselves of having erectile dysfunction need not be afraid to seek help. There is a variety of treatments available.

One such treatment is the oral drug called sildenafil citrate, commonly known by its brand name Viagra. It is classified as a phosphodiesterase-5 or PDE-5 inhibitor. Along with other PDE-5 inhibitors, sildenafil is considered the first-line treatment for erectile dysfunction.

Phosphodiesterase-5 is an enzyme that breaks down cGMP, a molecule that facilitates relaxation of the penile smooth muscle and the resulting erection. By inhibiting PDE-5, Viagra increases the amount of cGMP in the penile smooth muscle, thereby aiding in the initiation and maintenance of erection.

Viagra is available as a 25 mg, 50 mg or 100 mg tablet. After intake, an erection is feasible in about an hour and can be sustained for about 6 hours. Men who are taking nitro-glycerine and other similar drugs should avoid Viagra and ask their doctors for other options because it could lead to hypotension. Because PDE-5 receptors are also found in the retina, it affects colour vision. Men will know that they have overdosed when they have difficulty discriminating between blue and green. 

The Problem of Erectile Dysfunction

Erectile dysfunction (ED) or impotence occurs when a man is repeatedly not able to get an erection or keep one long enough for the duration of a sexual encounter.  This is caused when not enough blood flows to the penis, thus, preventing an erection.  Erectile dysfunction is a very common male problem with more than half of men over 40 suffering from the problem to some degree.

Age can play a factor in impotence, but it is not the same for everyone.  While some men may be able to achieve an erection but may have difficulty getting their erection to last.  Others are unable to produce an erection hard enough for sex or can only sustain brief erections.  Yet, there are men who are consistently not able to get an erection at all.

It is these variations that make diagnosing ED difficult.  It is estimated somewhere between 15 and 30 million men suffer from the condition.  Erectile dysfunction is a medical condition and in most instances, the condition will not improve on its own without medical treatment.  One of the most commonly used drugs for erectile dysfunction is Viagra.

Any disorder that causes injury to the nerves or physical injury, disease or side effect of drugs can cause erectile dysfunction in older men.  The incidence increase with age, with 5 percent of 40+ being affected compared to 15 to 25 percent of 65+ men experiencing bouts of ED.

Viagra has been around the ED market for more than ten years with much proven success.  It can safely treat men with erectile dysfunction who have other health concerns.  Viagra can help improve erections, making them harder and last longer and works with most men who have ED.

Erectile Dysfunction Treatments – Viagra

What is Erectile Dysfunction?

Erectile dysfunction is also known as ED or impotence and occurs when a man is unable to get or maintain an erection because not enough blood is flowing to his penis.  Men who are stressed, overworked, drink too much alcohol or who are over 50 are those who are more likely to encounter this embarrassing condition.

Men suffering from erectile dysfunction do not all have the same symptoms.  Some men fail to achieve an erection at all.  Others achieve an erection but find it difficult to maintain it, or find that their penis is not hard enough for penetration.

Erectile dysfunction is not an imaginary condition; it is a genuine medical condition and as such requires medical treatment.  An effective treatment of erectile dysfunction is Viagra.

Viagra

Viagra is taken in tablet form and is a tried and tested treatment of erectile dysfunction.  For more than ten years men have been taking Viagra to treat this common condition and the side effects are rare.  These side effects include headaches, facial flushing and upset stomachs.  In very exceptional circumstances some men may suffer problems with their vision.

The best way to obtain Viagra is to visit a local GP where you can discuss general health and any concerns.  If this proves too embarrassing then you can also buy the drug online.  Make sure that if you do buy Viagra online, check that the online pharmacist is a verified internet pharmacy site and that the drug is a genuine product.  Many sites sell counterfeit tablets.

What is Erectile Dysfunction and how is it treated?

Most men will encounter impotence at least once during their lifetime, caused by either a physical or psychological reason.  Stress, too much alcohol or overwork may lead to a man unable to maintain an erection and achieve a sexual climax.  The reduction in sexual pleasure affects not only sufferers but also their partner who they may not be able to penetrate.  The physical aspects can quickly lead to psychological symptoms such as depression and may be responsible for relationship problems.

Men can be embarrassed by this condition but it may be only a temporary phase that can easily be remedied.

However, for approximately two million men in the UK, impotence is not a temporary issue and the long-term condition is known as erectile dysfunction.  The majority of sufferers are men over the age of 50 who are more prone to the condition.

There are drugs that you can obtain that are available online, meaning that the patient can avoid an embarrassing visit to his local GP.  Online pharmacists ensure that any purchase made over the internet is discreet and confidential.

Cialis is one remedy that is taken orally in tablet form and increases the blood flow to the penis allowing the man to have a lasting erection.  The tablet is taken 30 minutes before sexual intercourse and the effect last for 36 hours.

Viagra is another remedy and works in about an hour, although for some men it can take effect within 14 minutes.  Take Viagra on an empty stomach and once you receive an orgasm, your erection will disappear.

The importance of genuine medication

We all know that it is possible to buy medication online which often refers to the manufacturers’ name for the medication, Viagra, or Priligy is a case in point where the site refers to the product as Viagra or Priligy, but is it genuine or is it a fake? The difference sometimes becomes glaringly obvious when a user switches from a name-brand drug to its generic counterpart. While the active ingredient is bio-equivalent in both and designed to produce the same effect, the rest of the formulation is not.

While patients often assume that they are allergic to an active ingredient in the drugs, allergies to medications may actually be due to the inactive components, such as gluten, artificial colourings, preservatives and other chemicals that maintain the appearance, but do not serve any medical purpose. The answer is simple; only buy genuine Viagra or Priligy online from a trusted source.
