Impotency drug has the most sales out of any wide array of drugs that are available world wide, though Viagra has an unchallenged monopoly for 7 long years but the year 2003 must’ve really got them at the edge of their seats as at last their monopoly was challenged and the icing on the cake was that not only by one competitor but two and that also with new improved and advanced technology that addressed some of the drawbacks that Viagra was not able to get hold of.

Cialis was the one that really turned out to be Viagra’s nightmare, snatching 27 percent of its market share and with sales growing every year and last year crossing the magical figure of $1 billion. One of the startling ability of Cialis was that its effect lasted for 36 hours in comparison to Viagra’s and Levitra’s 4 hours half-life. Below are some of the core differences discussed as their mechanism for functions fundamentals are almost the same as they all work by inhibiting PDE 5 enzyme.

Cialis is a great choice for the men who are very sexually active because it works within fifteen minutes and lasts for up to thirty six hours.

Levitra works faster than Viagra. It should be taken one hour prior to sexual activity. It works faster on a stomach that is full. It works more efficiently on cases in men which are hard-to-treat when diabetes is the cause of the impotence.

Viagra is used by 20 million men, worldwide. It works in one half hour to one and one half hours and lasts for approximately four hours. 98% of prescriptions for impotence are for Viagra.

There has been a lot of talk going on about researchers working to find something similar to impotency drug that treat Female Sexual Dysfunction or a low libido. But so far there is no major break through in that area reported except some minor successes, as what they observed after giving the drug that it caused the usual effect on males where the maximum the dose; the blood vessels would relax directly proportional to that but it has an altogether different effect on female blood vessels where there was an odd oscillation between relaxation and contraction, which later findings proved that it was primarily because of the female smooth muscle cell communication between internal pudendal arteries which acted opposed to that of male smooth muscles cells that make an independent decision to relax as they don’t have to communicate with another system.

The reason why still researchers have been unable to come up with a concrete remedy for Female Sexual Dysfunction or their low libido complaints post menopause because in contrast to male sex drive which only requires a raging hard on and that is more like a switch which only awaits to turn on; female sexual process is very complex as it involves Psychological, Physiological and Environmental aspects that are greatly affected by multiple elements. But the good news is that a lot of effort is put into this niche as this is challenge but if cashed properly then it can be changed into opportunity.

It might be an alien concept for many but this is very much true; not just true but its effects were even very impressive. The use of impotency drugs can be used to cure many other diseases as well. Tadalafil was recently in May 2009 approved in the United States for the treatment of Pulmonary Arterial Hypertension and many doctors have been witnessed prescribing it for Raynaud’s Phenomena

An average blood pressure reading of more than 140/90 lies under the category of high blood pressure. High blood pressure occur when the pressure within blood vessels is too high and if it is not treated in time, then that can result in some serious repercussions, such as heart attack and kidney failure. It is available under the brand name of Adcirca to avoid the confusion with Cialis, it works by blocking phosphodiesterase-PDE5 enzyme in the body. This helps to relax the blood vessels in the lungs. Decreasing high blood pressure in the lungs allows the heart and lungs to work better.

Another use of it is to treat Raynaud’s Phenomena where the blood vessels in the fingers, toes, ears, and nose gets narrowed it is called Vasospastic Attack. Raynaud’s phenomenon can either occur on its own, or it can be secondary to another condition, such as scleroderma. Adricia is also prescribed here though it is not an approved way of treatment but it does works well, as its core function is the inhibition of PDE5 enzyme that make the contracted vessels relax.

In 1993 when GlaxoWellcome and Icos Corp were working on this compound of IC351; no body knew that what they were working on as they were testing primarily its usefulness for the treatment of disorders. They patented it in 1994, though Pfizer in 1994 discovered Sildenafil’s (Viagra) ability to cause penile erection and they later patented it in 1996 but this duo of GlaxoWellcome and Icos Corp later in 1997 after the results of clinical tests came to knew about IC351 can also cause penile erection. Then they further studied and it later in 2003 it was available at the shelves of the Medical Stores as Cialis generic name Tadalafil.

The main ingredient of Cialis is substance of, Tadalafil code named IC351, belongs to a group of medicines called ‘phosphodiesterase type 5 (PDE5) inhibitors’. It works by blocking the phosphodiesterase enzyme, which normally breaks down a substance known as cyclic GMP (cGMP). During normal sexual stimulation, cGMP is produced in the penis, where it causes the muscle in the spongy tissue of the penis (the corpora cavernosa) to relax, allowing the flow of blood into the corpora, producing the erection. By blocking the break down of cGMP, Cialis restores erectile function. However, sexual stimulation is still needed.

Nothing in this world is perfect and so is the case with the drugs, their performance is constantly regulated and checked for the purpose of improving. Some of the researches that have been carried out by monitoring the effect of the drug on the user or either test it in a controlled environment. The tests are either focused to how well it is tolerated in different users or its reaction with other medication used alongside Cialis.

Cialis was used on women who used Serotonin excessively which resulted in sexual dysfunction in women. Three women with medication-induced sexual dysfunction derived benefit from using 20 mg of Cialis before anticipated sexual activity. It countered the effect created due to increased intake of Serotonin drugs.

It was witnessed in one of the researches that were to investigate the usual side effects of back pain and/or myalgia to understand its mechanism and reason to occur. An integrated analysis of 10 placebo-controlled Cialis clinical trials showed that the incidence of back pain and/or myalgia was 9% in patients receiving Cialis 10 mg, 8% in patients receiving Cialis 20 mg and 3% in placebo-treated patients. Although the mechanism of back pain and/or myalgia remains unknown, these Cialis side effects appear to be self-limiting and a general effect of phosphodiesterase 5 inhibition.

There has been many talks of not taking any medication while you are on Cialis as that can be very dangerous. But what if it is inevitable; here one such study is discussed where the hypertension is discussed and its first line therapy Thiazide reaction to Cialis.. Data was analyzed from 14 randomized, double-blind, placebo-controlled trials to evaluate the efficacy of Cialis 20 mg for the treatment of ED in men on Thiazides. Of the 2501 patients, 163 were on concomitant Thiazides (116 Cialis /47 placebo) and 159 (98%) were reported to have hypertension. The Cialis group showed a significantly greater mean baseline to endpoint improvement on all efficacy outcome measures compared to placebo-treated patients regardless of concomitant Thiazide use. More importantly, the responses to Cialis were similar regardless of concomitant Thiazide use.

Cialis and other impotency drugs for erectile dysfunction; their fundamentals for functioning are same but what distinguish Cialis from rest of the squad is its fascinating ability of its effect to last longer than any other impotency drug, which is up to 36 hours, that is 17.5 hours half-life in comparison to the number one impotency drug for erectile dysfunction Viagra having 4 hours of half life time. This earned Cialis the name of “Weekend Pill” and unlike others it can also be taken as once a daily.

The erection of penis and its rigidness during sexual stimulation is the direct result of the increased flow of blood through chambers corpora cavernosa; one for inflow and other for outflow that causes the loss of erection. This accumulation of blood is caused due the relaxation of muscles of corpora cavernosa that is implemented through the occurrence of certain chemical reactions where the nerve terminal releases Nitric Oxide and endothelial cells, which provides the enabling environment to inhibit the enzyme and thus the muscles remain relaxed and the accumulated blood does not exit through the outflow chamber of corpora cavernosa. Now what Cialis does is that it inhibits the enzymes that are responsible to make the corpora cavernosa muscles to contract and let the out flow of blood from the penis possible by not letting the chemical reaction to occur.

Since this drug meddles with the entire working of your internal system as it inhibits many enzyme and chemical reaction either stop them from occurring of disturbs their usual routine in such cases those people who are already going through some instability through out their body, so in such state taking Cialis would do nothing but add fuel to the fire; make things go out of hand and bring dire consequences.

Those people having any medical history related to heart diseases, diabetes, high blood pressure, high cholesterol or pre-existing eye problems. They should seriously consider about taking a professional advice before taking this drug, as it primarily pry with the functioning of the heart and a little undesired can bring drastic eventualities. As it causes serious decrease in blood pressure that can lead to fainting, stroke or even heart attack.

Also a sudden loss of vision has been reported in some users, which is because of the sudden decrease of blood flow to the optic nerve of the eye and is limited to only those people who either smoke or are over 50 years of age.

It is also not recommended during pregnancy though there are no proofs that indicate that it passes into the breast milk or harm the new born but having said that; prevention is better than cure.

To many it might sound strange but the other available impotency drugs that focus on erectile dysfunction the side effects which they come with despite the fact that the mechanism with which Cialis and they work is the same but Cialis does not comes with the side effects those other impotency drugs come with; but unfortunately that does not means that Cialis is free from any side effects, here in Cialis the nature is a bit different of those adverse effects being reported but with the passage of time their impact minimizes.

Cialis and other impotency drugs for erectile dysfunction all act by inhibiting the PDE5 enzyme. These drugs also inhibit other PDE enzymes. Viagra and Levitra inhibit PDE6, an enzyme found in the eye, more than Cialis. Some Cialis users see a bluish tinge and are highly sensitive to light because of PDE6 inhibition. Viagra and Levitra also inhibit PDE1 more than Cialis. PDE1 is found in the brain, heart, and vascular smooth muscle. It is thought that the inhibition of PDE1 by Viagra and Levitra leads to vasodilatation, flushing, and tachycardia. Cialis inhibits PDE11 more than Viagra or Levitra. PDE11 is expressed in skeletal muscle, the prostate, the liver, the kidney, the pituitary gland, and the testes. The effects on the body of inhibiting PDE11 are not known.

Cialis is though known basically for making things go up but hardly any one would’ve said that for it sales graph before its inception specially having a mighty rival having established its name and working for 7 years now; Viagra but since its advent into the world of impotency drugs it sales are increasing for the very first day of its launch and to very extent that it has shook the market share of Viagra by 27 percent.

The main reason behind its commercial success is its effect lasting up to 36 hours and comparatively lesser side effects reported using other brands. Though the initial rifts of management and controversies resulted in decline of its share prices but with the settling of the disputes between the aggrieved parties, in the next fiscal year it did covered up all the losses.

In the fiscal year 2004 Cialis had worldwide sales of up to $550 million and followed in by sales of $746 million in 2005 and again witnessing a sharp upsurge in 2006 of sales up to $971 million. A startling $1 billion in 2007 followed by a year marked with destabilization, economic crunch and recession though managed to muster good sales of $1.075 billion in 2008.

This shows that it has not only sustained but developed progressed and evolved as a trusted and reliable brand commercially and otherwise.

Cialis is for treatment of erectile dysfunction and those who have benefited from it would say that it’s God sent and a reply to their endless prayers; and those didn’t find it to their satisfaction would say that its just another gimmick pulled off to steal money from their pockets but bad news for all of them is that they are incorrect.

In 1991 then GlaxoWellcom (now Glaxo Smithklien) and Icos Corp under a partnership to develop new drugs discovered Tadalafil. As in 1993 Icos Corp began to study the compound IC351 and they were testing its usefulness and treatment for disorders. Later Icos Corp patented it in 1994 and in 1997 in clinical tests they found out its effectiveness for erectile dysfunction.

In 1998 Icos and Eli Lilly formed Lilly Icos Co for the development and commercialization of Tadalafil; as GlaxoWellcome let the agreement between Icos Corp and them lapse in 1996 as the drugs developed were not in their core markets.

Two years later in 2000 it was filed with United States Food and Drug Administration (FDA) for generic name Tadalafil and brand name Cialis. In 2003 FDA approved Tadalafil for the use of erectile dysfunction and in May 2009 has been recognized for the treatment for pulmonary arterial hypertension.
