The approval by the United States Food and Drug Administration of the three erectile dysfunction drugs including Levitra may have paved the way for the distribution of Levitra in the market but it has also spawned the proliferation of pseudo Levitras in the market. The fake Levitra is sold in any form, sometimes a perfect look-alike of the drug while other manufacturers distribute it as herbal Levitra.
Those who lack information can commit the mistake of buying the fake
or herbal Levitra with the belief that it has the same effects as the
original and cheaper at that. However, take a look at the pros and cons
of buying the real Levitra versus the fake Levitra before you decide
which one is best for you.
Safety The safety issue should be the number one concern
among users of any medication, be it original or imitation. Levitra is
a regulated drug and its approval by the US FDA is proof that it is
safe for public use. The problem with the herbal or imitation Levitra
is that no agency is regulating its contents. This means that it can
claim to contain ingredients that are actually non-existent or vice
versa. The safety of what it contains is also a concern.
Dosage While other can argue that herbal medications are
generally safe because it contains only natural ingredients, there is
still the problem of ascertaining whether the herbal medicine actually
contains what it purports to contain. The dosage of its contents also
could not be ascertained since it is not regulated. Levitra on the
other hand, is available in various preparations and your doctor can
prescribe which dosage is right for you.
Accountability Levitra is produced by Bayer Pharmaceuticals
Corporation and it is accountable for any effects that Levitra may have
on its users. The manufacturers of herbal and other fake Levitras are
however small or unknown manufacturing firms or they can even be
home-based manufacturers without the proper laboratory equipment to
test the efficacy and safety of their products.
Generic Some may argue that they are buying herbal
preparations of Levitra which are considered the generic version of the
drug. However, there is as yet no generic Levitra because it is still
under patent and only Bayer has the legal right to manufacture the
drug. Those producing the generic version of Levitra are not regulated
and have not been tested by the FDA for safety and efficacy.
Determining the real Levitra So how to determine the real Levitra? The authentic Levitra
has an orange-yellow color with the Bayer cross trademark. It is being
marketed by GlaxoSmithKline. Levitra is widely available in US
pharmacies and it can even be purchased online. However, you need to
have a prescription before you can buy it personally or online.

Statins Might Reverse ED in Some Men (HealthDay)
HealthDay - FRIDAY, Aug. 15 (HealthDay News) -- Statins might quickly help
reverse erectile dysfunction among men who have metabolic syndrome, new
animal research suggests.
Erectile dysfunction (ED) affects the lives of many middle-aged men and their partners. The term erectile dysfunction covers a range of disorders, but usually refers to the inability to obtain an adequate erection for satisfactory sexual activity.
Although erectile dysfunction, formerly called impotence, is more common in men older than 65, it can occur at any age. An occasional episode of erectile dysfunction happens to most men and is normal. As men age, it's also normal to experience changes in erectile function. Erections may take longer to develop, may not be as rigid or may require more direct stimulation to be achieved. Men may also notice that orgasms are less intense, the volume of ejaculate is reduced and recovery time increases between erections. Erectile dysfunction may also be a sign of a physical or emotional problem that requires treatment.
Erectile dysfunction was once a taboo subject, but more men are seeking help. Doctors are gaining a better understanding of what causes erectile dysfunction and are finding new and better treatments.
This Website discusses all about erectile dysfunction, physiology of the normal erection and the pathophysiology, and treatment of ED.
What is Erectile Dysfunction?
Erectile dysfunction or impotence is a sexual dysfunction characterized by the inability to develop or maintain an erection of the penis for satisfactory sexual intercourse regardless of the capability of ejaculation. There are various underlying causes, such as diabetes, many of which are medically reversible.
The causes may be physiological or psychological. Psychological impotence can often be helped by almost anything that the patient believes in; there is a very strong placebo effect.
Due to its embarrassing nature and the shame felt by sufferers, the subject was taboo for a long time, and is the subject of many urban legends. Folk remedies have long been advocated, with some being advertised widely since the 1930s. The introduction of perhaps the first pharmacologically effective remedy for impotence, sildenafil (trade name Viagra), in the 1990s caused a wave of public attention, propelled in part by the news-worthiness of stories about it and heavy advertising.
The Latin term impotentia coeundi describes simple inability to insert the penis into the vagina. It is now mostly replaced by more precise terms.
Signs and symptoms:
Erectile dysfunction is characterized by the inability to maintain erection. Normal erections during sleep and in the early morning suggest a psychogenic cause, while loss of these erections may signify underlying disease, often cardiovascular in origin. Other things leading to erectile dysfunction are diabetes mellitus (causing neuropathy) or hypogonadism (decreased testosterone levels due to disease affecting the testicles or the pituitary gland).
Here are some causes of Erectile Dysfunction:
* Arousal: The first step is sexual arousal, which men obtain from the senses of sight, touch, hearing and smell, and from thoughts.
* Nervous system response: The brain communicates the sexual excitation to the body's nervous system, which activates increased blood flow to the penis.
* Blood vessel response:. A relaxing action occurs in the blood vessels that supply the penis, allowing more blood to flow into the shafts that produce the erection.
Physiology of normal erections:
Penile erections involve an integration of complex physiologic processes involving the CNS, peripheral nervous system, and hormonal and vascular systems. Any abnormality involving these systems, whether from medication or disease, has a significant impact on the ability to develop and sustain an erection, ejaculate, and experience orgasm. Tumescence, the vascular filling of the cavernous bodies, relies on neural and hormonal mechanisms operating at various levels of the neural axis. This is unique among visceral functions because it requires central neurological input.
Andersson et al summarized some of the information related to the pathways involved in erectile function. The degree of contraction of corpus cavernosal smooth muscle determines the functional state of the penis. The balance between contraction and relaxation is controlled by central and peripheral factors that involve many transmitters and transmitter systems. At the cellular level, smooth muscle relaxation occurs following the release of acetylcholine from the parasympathetic nerves.
Pathophysiology of erectile dysfunction:
Erectile Dysfunction is essentially a vascular disease. It is often associated with other vascular diseases and conditions such as diabetes, hypertension, and coronary artery disease. Other conditions associated with Erectile Dysfunction include neurologic disorders, endocrinopathies, benign prostatic hyperplasia, and depression. Conditions associated with reduced nerve and endothelium function, such as aging, hypertension, smoking, hypercholesterolemia, and diabetes, alter the balance between contraction and relaxation factors. These conditions cause circulatory and structural changes in penile tissues, resulting in arterial insufficiency and defective smooth muscle relaxation. In some patients, sexual dysfunction may be the presenting symptom of these disorders.
Treatment:
Sildenafil Citrate is the way to treat Erectile Dysfunction. Generic Viagra contains sildenafil citrate and contains same ingredients like branded drug.
