Half-lives of Viagra, Cialis and Levitra phosphodiesterase type 5 inhibitors

Phosphodiesterase type 5 inhibitors, (aka PDE5 inhibitors) remain in effect for disparate durations and this is expressed half-lives.

Cialis continues to be in effect for up to eighteen hours – or in other words if a sufficient amount is ingested it stays present to some degree in the body for up thirty-six hours.

Viagra and Cialis ED pillsVardenafil and Sildenafil have a half-life of up to 4 hours delivering relief to erectile dysfunction symptoms for at least that long and remains present in the body for up to eight hours – if a large enough dose for the subject is digested.

All three oral PDE5 inhibitors are eliminated from the body by means of urination.

PDE5 inhibitors are eliminated from the body via metabolism.

Metabolite N-desmethyl is the by-product of metabolised Viagra oral PDE5 inhibitor (Sildenafil) which additionally results in PDE5 inhibiting properties. This by-product of Viagra remains around 20% as potent as the initial PDE5 inhibitor Sildenafil.

The metabolite by-product of the PDE5 inhibitor Vardenafil (Levitra) has just a 7% strength of the original PDE5 inhibitor.

Tadalafil , the PDE5 inhibitor used in Cialis, results in no effective substances after breakdown.

Viagra vs Cialis vs Levitra review : PDE5 inhibitor absorption and activation rates

Neither Viagra, Cialis, nor Levitra, are activated right after after ingesting and tests have demonstrated that there is considerable range among all three PDE5 inhibitors as well as remarkable variations among the men affected in this study.

On average all three PDE5 inhibitors activate between half an hour to one hour after taking but observable divergence outside these times have been observed.

The most common refrain repeated by the pharmaceutical industry regarding the expected time-scale between swallowing Viagra and its time of effectiveness to overcome erectile dysfunction symptoms is  30 to 60 minutes, often less.

In reports from another study, just over one-fifth of men involved reported being able to enjoy erections capable for full sexual intercourse within 10 minutes after ingesting 10mg of PDE5 inhibitor Vardenafil (Levitra). The accepted recommendation for Levitra is to take it 25 to 60 minutes before attempting penetrative intercourse.

The accepted recommendation for Cialis (Tadalafil) is to take it around 30 minutes prior to attempting penetrative sexual activity. An alternative result has indicated that approximately over 15% of the test subjects were able to preform intercourse in around 20 minutes.

Viagra vs Cialis vs Levitra : duration of effectiveness

The PDE5 inhibitors employed in Viagra, Cialis and Levitra have distinct lengths of duration in their effect.

Viagra vs CialisUsual information that ships with Sildenafil (Viagra) and Vardenafil (Levitra) suggest a 4 hour plus time-scale these ED medication’s continued effectiveness.

Tadalafil (Cialis) incorporates a much longer half-life length of 17.5 hours and therefore the effects of Cialis impotence treatments are thought to remain effective for up to to thirty-six hours.

This length of effectiveness makes Cialis a top selection of erectile dysfunction drug for patients who would like to be able to perform more unplanned sexual activity.

Tests show that all three PDE5 inhibitors reviewed here are beneficial for a broad band of people experiencing ED. Currently there still is a dearth of comparative tests of the ED treatments Viagra, Cialis and Levitra.

Additional direct comparative tests of these oral PDE5 inhibitors under review are required to be held before a definitive judgement of their effectiveness can get accurately gauged.

Viagra vs Cialis vs Levitra: potency and success rates

Improvement for erectile dysfunction patients resulting from a 90 day period of ingesting these erectile dysfunction oral PDE5 inhibitors comprising of over 100 subjects taking Levitra, 320 men trying Viagra and over 1,000 subjects using Cialis , produced the subsequent numbers:

75% of the test subjects who tried Viagra 50mg had an improvement of erections when sexually aroused over the course of the test – while only 16% of subjects who took a placebo experienced in improvement in their ability to achieve erections when sexually aroused.

Viagra vs Levitra vs Cialis chartOut of the men who were given Levitra 20mg over a 3 month test, over 80%  had a significant improvement in their capacity to experience erections when sexually stimulated. Almost 40% of men consumed a placebo experienced erections when sexually stimulated.

The subjects of the observations where in their mid-fifties and had previously suffered various levels of ED ranging from occasional to constant inability to achieve erections when sexually stimulated for up to six years beforehand.

In one other study lasting 90 days testing the potency of Tadalafil PDE5 inhibitor (Cialis), over 80% of the men enjoyed an observable increase in their capacity to have an erect penis sufficient for full penetration.

Of those patients who consumed placebo, 33% percent reported an increase in their capacity to achieve an erect penis.

These observations included men in their fifties who had suffered ED for over 1 year. The level of ED suffered by the men alternated between moderate (40%) to severe (60%).

Lab test subjects who had previously failed to respond to PDE5 inhibitors were not used in these experiments.

In the trials cited in this Viagra vs Cialis vs Levitra review it was asked: was your erection of adequate hardness and duration to engage in penetrative intercourse? A positive response to this question was 65% for Viagra and Levitra, and 68% for Tadalafil.

Viagra vs Cialis vs Levitra review: aims and preferences

The main aim of ED pills such as Viagra, Cialis and Levitra is to facilitate sufficient capability for achieving penile erections when stimulated and the capacity to achieve a fuller and more rewarding sexual life.

Therefore the requirements and distinct preferences of the individual must be acknowledged when making available impotence medication.

Because the rate of response and results of the three major PDE5 inhibitors are more or less the same, the choices of the patient must be taken into account prior to making a course of action.

Viagra vs Cialis: the reasons men prefer Cialis over Viagra

To measure patient preference between Cialis and Viagra a double-blind crossover study was set up incorporating just over 200 patients. The strengths were a variable amount of Viagra (between 25mg to 100mg) and 20mg of Cialis.

Men taking Viagra started on 50mg with the option to up the dose later.

Because instructions regarding effect durability for Viagra and Cialis are different, placebos mimicking both PDE5 inhibitor guidelines were used to ensure blindness.

Also a random selection as to which subjects received Viagra and Cialis with a 12 week exchange from one PDE5 inhibitor to the other. By the end of the experiment there were 180 patients who could be considered as suitable to make a choice over which ED treatment they wanted to purchase.

At the termination of the test study it was discovered that approximately 70% of the subjects clearly chose Cialis vs Viagra as their preferred erectile dysfunction treatment.

An additional lab study used subjects experimenting with strengths of Viagra between 25mg to 100mg for a time-scale of 6 weeks, and then switching to Cialis at a standard dose of 20mg.

This study attempted to mimic standard laboratory practice and the resulting figures showed definitively that around 90% of the men preferred Cialis vs Viagra.

erectile dysfunction treatments reviewAnother study conducted in Ireland to document the preference for Viagra vs Cialis, over over 300 subjects were involved in the study over 12 weeks for each PDE5 inhibitor.

The initial 8 weeks trying either Cialis or Viagra was the dose optimisation phase where patients chose the most appropriate dosage for each PDE5 inhibitor.

The patients started off with with 25mg or 50mg of Viagra and were allowed to increase the dosage to 100mg if they desired. The test subjects also began with 10mg of Tadalafil and were allowed to up the dosage to 20mg if they chose to.

After the 12 week experiment phases with Viagra vs Cialis were completed the subjects were offered a choice on which erectile dysfunction pill they wished to stay with. 30% of the subjects wished to continue with Viagra and 70% selected to stay with Cialis.

The patient’s decisions did not appear to be influenced by the order of testing, level of ED suffered beforehand, the patient’s age or strength of PDE5 inhibitor selected.

3% of the test subjects quit due to negative side effects and point 0.7% quit the test study because of an absence of any noticeable beneficial result.

These trials amply show that patients choose their favourite ED tablets founded on effects experienced. However the approaches utilized in these tests of ED treatments the men’s selection employed methods that might introduce bias in choosing in the test subjects of the lab study.

Technical problems were observed. To name a few: gaps in blindness, sequence order of crossover, and numerous dosage strengths and changing guidelines. The guidelines for use varied due to the differences in length of effect as well as the  influence of some kinds of food upon the effectiveness of Viagra and Cialis.

Keeping in mind that the test subjects were issued user guidelines appropriate for the erectile dysfunction treatment being taken (Viagra or Cialis) in that period, it is highly unlikely that any reaction or experience of its effectiveness were distorted by the methodology of this Viagra vs Cialis review.

Even though this lab study accounted for possible discrimination, more thorough tests are under way to clearly identify ED sufferer’s preference of the 3 major PDE5 inhibitors, namely, Viagra vs Cialis vs Levitra.

Viagra vs Cialis vs Levitra comparisons: conclusions

Following from the interest and large use of erectile dysfunction medications, the difficulty and cost to acquire these ED treatments namely Viagra, Cialis and Levitra, have been drastically reduced.

The easy availability of cheap generic Cialis online as well as other erectile dysfunction tablets have notably put these effective impotence cures within the reach of most men who suffer varying degrees of ED.

Cialis vs Viagra chartThe 3 most popular PDE5 inhibitors are an inexpensive method to cure the vast majority of erectile dysfunction problems. Mindful that the effects remain for a much longer duration, Cialis could be considered the more affordable erectile dysfunction treatment especially if the impotence sufferer wants to take advantage of erectile dysfunction tablets for the long-term.

When it comes to erectile dysfunction drugs, PDE5 inhibitors continue to be the most effective, simple to administer, and cost-effective approach. The three main PDE5 inhibitors, Sildenafil, Tadalafil and Vardenafil, usually marketed as Viagra,Cialis and Levitra, enjoy many identical characteristics being both effective and well-tolerated by the majority of users.

From a wider perspective however, the medical establishment must keep in mind the discrepancies among the oral PDE5 inhibitors when precribing these medications to individual erectile dysfunction sufferers. Only then can it could be assured that every ED sufferer derives the most benefits for his requirements and help in the restoration of his previous capacity to enjoy a full sex life.

Admittedly, although this Viagra vs Cialis vs Levitra review covers a wide area of contention which is seemingly endless, it is impartial to remark that by choice, Cialis maintains the lead in the battle of ED pills.

Nevertheless it should be remembered that this erectile dysfunction treatments review indicates that sometimes Levitra and Viagra might be more successful than Cialis in curing erectile dysfunction.
