The Difference between Cialis, Levitra and Viagra
Cialis, Viagra and Levitra are prescription medications of alike mechanisms aimed to strengthen natural reaction on sexual excitement of a mans organism, which intensify blood afflux to the penis, and provide a full erection.
Viagra is the most well-known ED medication.Generic Viagra, presented in our pharmacy, is a full analogue to Brand Viagra in terms of its action and chemical composition, intended to intensify the potency in men suffering from erection disorders, including the ultimate form of an erectile dysfunction (ED) - impotence. This disorder is specified by absence of an erection sufficient to carry out a sexual intercourse, or by an impaired erection. ED may be invoked by various reasons both of a psychological character and a physiological one. According to the results of clinical tests the application of Viagra is effective in about 80 per cent of the cases of erectile dysfunction. Viagra provides blood afflux to the penis and prevents its reflux, in doing so the erection does not arise involuntary, but only in response to sexual excitement. It means that Viagra does not substitute natural processes of sexual excitement, but only intensifies them. Moreover, Viagra makes pathway to oxytocin in the brain, a hormone which awakes romantic feelings. Viagra does not influence mans reproductive functions.
Levitra is the safest medication.Medication Levitra is the newest product, an innovation in the field of ED medications. In some cases it is not recommended to cure erectile dysfunction with the use of such medicines as Cialis and Viagra, for instance, in patients with diabetes and cardio ischemia. At the same time, among the factors which in the first place lead to the progression of erectile dysfunction, one may attribute cardio-vascular diseases, smoking, fatness and diabetes. Moreover, Levitra is an extraordinary efficient medication, its initial dosage is only one fifth of that of Viagra, and so it reduces the risk of side effects and their intensity. Thus, one may say that Levitra has a larger safety profile, especially for men suffering from cardio-vascular diseases and diabetes. Also Levitra is three times superior Viagra in terms of duration of the effect, providing the readiness of men to a sexual intercourse during 12 hours after intake.
Cialis is the most efficient medication.Generic Cialis is a full analogue to Brand Cialis in terms of chemical composition and action, intended to intensify the potency in men suffering from ED. Cialis provides blood afflux to the penis, in doing so the erection does not arise involuntary, but only in response to sexual excitement. It means that Viagra does not substitute natural processes of sexual excitement, but only intensifies them. Cialis does not influence mans reproductive functions. The main difference of Cialis from Viagra, in the first place, is a less quantity of minimal necessary active substance. If for Viagra the minimum necessary dose is 25 mg. (in most cases the minimum necessary dose of the medication is 50 mg), for Cialis it is 20 mg. This difference provides lesser risks of side effects and their less intensity. One more critical difference of Cialis from Viagra and Levitra is a prolonged time of effectiveness. If effectiveness time of Viagra is 4 hours, that of Levitra is 12 hours, whereas the effectiveness time of Cialis is 36 hours.
History: treatment of ED
Long time before urologists recognized the physical nature of impotence, treatments generally fell into three categories-aphrodisiacs, and mechanical treatments.
AphrodisiacsOysters, lobsters, eggs, and spices are examples. Spanish Fly, a substance made by grinding the wings of certain beetles, was a favorite of that party animal, the Marquis de Sade. It is illegal in the United States both because of the unproven nature of its effectiveness and a tendency to cause seizures or death. Many of these substances actually do nothing more than irritate the genital organs. The user interprets this irritation as increased sensitivity, thereby giving the impression of increased performance. Rhinoceros horn has been used (unsuccessfully) for so long that its name has become synonymous with sexual arousal. Unfortunately, its popularity has led to such widespread slaughter of the animals that they face extinction. Ancient Egyptians believed eating crocodile penises increased virility. Anyone capable of eating a crocodile’s penis probably didn’t need any more help proving his manhood.
Surgery/TransplantsThe Malleus Maleficarum was a guide to witchcraft during that era that asserted witch’s spells caused impotence. The idea of using animal testes to treat impotence began in the Middle Ages, when a standard treatment for “the male malady” was to place the testicles of a cock under the bed. Another option was eating the rooster’s testes. You could guess that putting them under the bed was much more popular. This was a major reason witch-hunting became so widespread. French physiologist Charles Edouard Brown-Sequard injected himself in the 1880s with an extract from the testicles of dogs that he claimed made him smarter, stronger, and more virile. After ten injections, he reported improved erections, as well as a stronger jet of urine and “power of defecation.” He made no claims about the effect this had on the dogs. His “Elixir of Life” became an instant best-seller. Its 1889 launch rivaled that of cheap Levitra, even without a famous spokesman.
MechanicalHot metal rods inserted into the urethra during medieval times failed to revive erections. No one wanted a second treatment, so failures went unreported. Many types of splints have been used, including hollowed-out antlers and horns. Encouraged by finding the penis bone (baculum) in some animals, early surgeons placed rib cartilage into the penis. Although these initial attempts failed, penile prostheses have more recently proven particularly reliable.
