Generally, what we understand when we first hear about Cialis is the fact that this is the first true competitor of Viagra as it fights against erectile disfunction as well as the first mentioned. Viagra appeared in 1998 and registered a high success generally for the fact that it was the first product of this kind. Nowadays a new successful product was attributed to ICOS corporation which is to shatter the unbelievable success of Viagra. The series isn't ending here, anyway,as another one called Levitra is expected to appear.
First of all, there should be mentioned that the sell market of Cialis has reached an enormous level which is bound to put aside the success registered by Viagra in the late 90's. What is important is the fact that from around thirty million people suffering from erectile disfunction in the USA and another estimated number of one hundred and seventy five million abroad who are having this disfunction and using these products, only a little part are using Viagra. Viagra has reached this year a total profit of $1,5bn, while the account of money used for these drugs(such as Viagra, Levitra and Cialis) raises up to $6.
Similar to the case of Viagra, Cialis should be understood as a general performance provider, to just a regular treatment for the ailment. Anyone of us should know that there is a specific process of these medication which makes them be so successful, while constantly improving our lives: they work by blocking an enzyme named phosphodiesterase (which happens to relax some of our muscles), this way allowing a certain growth of the blood flow in your penis.
Another advantage gained by Cialis over Viagra is the fact that it is available(by prescription only) in countries like the United Kingdom, Denmark, Finland, Sweden and Australia and it is ought to be approved in USA too.
Moreover, a common argument brought in favor of Cialis is the fact that it has more rapid effects than Viagra; The starting process can be reached at approximately sixteen minutes after taking the pill, while the entire process can lead up to twenty four hours or more. In contrast to that, by taking Viagra one may feel the effects after one hour and have them for four hours upmost.
Like Viagra, an estimated number of eighty percent of the people who have tried Cialis have had the opportunity and chance in the mean time to have an erection as well as sexual acts but in comparison with Viagra, the effects and potential of the user lasted for more than thirty six hours after taking the pill;in this period of time the effects were almost constant. A possible explanation for this is the fact that Cialis persists longer in the body than Viagra does. The period of time for blood levels to fall fifty percent for Viagra records four hours, while Cialis makes it up to seventeen hours. This can signify that a twenty five percent of the original doze of Cialis is still in the body at that time.
To conclude, it may be said that Cialis has finally shattered the' unbreakable' myth of Viagra by adding more tough points to the well-known advantages of Viagra. Logically, it is of a higher quality technique than Viagra this being the reason for the extreme surpassing. Let's hope things will not remain this way and will improve more and more up to perfection

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.
