Viagra vs. Cialis vs. Levitra: Differences and Similarities

A good point of view by John Scott Source

Ready to combat ED but confused about which type of PDE-5 inhibitor to take? You’re not the only one. Of the 3 FDA approved PDE-5 inhibitors, Viagra (sildenafil citrate) is definitely the most popular, but popularity alone shouldn’t be a determining factor. The more recently approved Cialis (tadalafil) and Levitra (vardenafil hydrochloride) are also highly effective and very safe alternatives, although they may not be as popular yet. The problem for most people is actually deciding on the best alternative for them.

For starters, all three drugs are PDE-5 inhibitors so they help relax compromised or hardened penile arteries thus allowing more blood to flow into the penis and subsequently cause an erection. All three drugs also help keep high levels of cGMP within the penis. What’s cGMP? It means cyclic guanosine monophosphate and it is an incredible substance which is naturally produced by the penile tissue in response to sexual stimulation and which aids vascular muscle relaxation. When high levels of cGMP are present, the penile arteries become relaxed and a natural and stiff erection will occur.

Unfortunately, in most men suffering from E.D., the PDE-5 enzyme neutralizes any available cGMP and without cGMP an erection will become flaccid or will not occur at all. That’s where PDE-5 inhibitors such as Viagra, Cialis and Levitra come in. These drugs “inhibit” or block the unwanted PDE-5 and hence the very much wanted cGMP is allowed to remain within the penis after sexual stimulation occurs, thus aiding the erection process and keeping the penis erect. The question is, “Since all of these drugs have the same effect, why should I choose one over another?”

Let’s compare the three PDE-5 inhibitors side by side to determine their differences:

Manufacturers:

Viagra: Pfizer

Cialis: Eli Lilly and ICOS

Levitra: GlaxoSmithKline and Bayer

Generic Name:

Viagra: Sildenafil Citrate

Cialis: tadalafil

Levitra: vardenafil hydrochloride

Dosages: Available and Recommended:

Viagra: 25 mg, 50 mg, and 100 mg tablets. Most patients begin using the 50 mg pill and either increase or decrease the dosage based on drug tolerance and / or effectiveness. Most healthcare practitioners recommend taking Viagra 1 hour prior to sexual activity but studies have shown that Viagra can actually be taken anywhere from 30 minutes to 4 hours before having sex.

Cialis: 5 mg, 10 mg, and 20 mg tablets. It is recommended that you start out using 10 mg tablets and either increase or decrease the dosage depending on the results achieved. Traditionally, Cialis tablets can be taken anywhere from 30 minutes to 12 hours prior to sexual activity. Cialis soft tabs (which need not go through the digestion process) may be taken around 15 minutes prior to sexual activity.

Levitra: 2.5-mg, 5-mg, 10-mg, and 20-mg. Most people start out on the 10 mg pill and either work their way up or down depending on the results achieved. Levitra should be taken anywhere from 25 minutes to 1 hour prior to sexual activity, though some experts claim sex can be initiated in as early as 15 minutes.

How long does the effect last?

Viagra: approximately 4 hours

Cialis: approximately 17 to 36 hours (This is why they call Cialis the weekend pill.)

Levitra: approximately 5 hours

Year approved by the FDA:

Viagra: March 27, 1998

Cialis: November 1, 2003

Levitra: August 20, 2003

Cost of Pill

The cost for each of the 3 drugs is similar though Cialis tends to be a bit cheaper.



Success Rate

All three drugs work for approximately 70 percent of all men. Unfortunately, PDE-5 inhibitors won’t work for everyone. Certain men may need to use alternative treatments such as vacuum pump devices or even penile implants.

Side Effects

All three drugs share most of the same side effects. Some men may experience headaches, flushing, back pain, runny noses, stomach aches, or even changes in vision (example: some Viagra studies have revealed that on rare occasions a man may begin seeing a bluish tinge but that should go away after the drug has been eliminated from the body). These are all common side effects and should not be reason to worry excessively.

None of the three PDE-5 inhibitors should be taken in combination with low blood pressure medication as this can potentially cause a person to have a heart attack. People with high blood pressure should also take PDE-5 inhibitors only after consulting with their doctor. In fact you should never self-prescribe yourself with any of the 3 PDE-5 inhibitors or any other prescription drug for that matter. Even if you are purchasing your PDE-5 inhibitors online you must still open up and tell the pharmacist everything he/she needs to know in order to properly formulate the correct treatment for you.

What the drug looks like:

Viagra: Small blue tablet with the word Pfizer engraved in the middle.

Cialis: Yellow tablet that is almond shaped and film coated.

Levitra: Orange tablet with a flame logo.

Notable Differences

Basically the only major difference between the three drugs is that Levitra begins working the fastest and will work regardless of what kind of food you have previously eaten. Viagra has the proven track record and has been trusted by over 30 million men and Cialis is the longest lasting. In the end though, the real choice is up to you.

Euphemistics: WARNING - content may offend

Do you ever look at your junk mail? I hardly ever do. Googlemail does an excellent job of chucking it directly into the spam folder and automatically deleting it after 30 days.

While having a little tidy-up this morning, I had a peep at the stuff awaiting deletion, and was quite entertained by the euphemistic phraseology used by the purveyors of sexual enhancement products.

Here are my three favourites today – and again, a warning, please do not read on if you think you might be offended, because if you think you may, then you probably will.

Vulcanize the whoopee stick more!    Whoooppeeeeeeeee!

Bring electricity back to your love circle.  Yikes! Sounds worse than waterboarding.

Energy to tear her ham wallet.    Pardon me? Her what?

Let's try Vigamed

One fellow with similar problems than me, drop a comment in this blog some days ago, and I’ve had the opportunity of have a little message exchange with him through a website we have in common.  I’ve tried Cialis, a  PDE-5 inhibitor, but in my case is useless because my anxiety blocks the desire and the excitement. His advices have been very good, and he discovered me this medicaments named Vigamed, so I’m gonna give it a try and see what happens. Maybe all my problems are in my head, but if I never feel like if “sex” is something that I’m able to do… the anxiety is gonna be always present in my mind at that moment.

Vigamed (phentolamine mesylate) can help to alleviate sexual dysfunction symptoms such as impotence, and ejaculatory failures. Phentolamine as an alternative to Viagra, Cialis, Levitra and Uprima has met with success with many men suffering from ED. Phentolamine works by directly or indirectly addressing the blood flow to the genitalia via several different biologic pathways. Two physiological systems, the sympathetic and the parasympathetic, play a role in sexual response. Phentolamine controls the erection process through the body’s sympathetic system allowing blood to flow into the penis to form an erection. 

Vigamed vs Viagra: The ability to control erectile performance via the body’s sympathetic system can speed up the erection process. Alpha adrenergic blockers, such as Vasomax (phentolamine mesylate), can produce an effect in as little as 15 to 20 minutes.  Viagra works to inhibit the enzyme phosphodiesterase, this process generally takes one hour or more.

I’ve seen some websites where the people says that it works.

I’ve bought it in an online pharmacy, it should be here in 7 days or something like that. Once I have it in my hands, I’ll trace a plan for test it … and of course I’ll explain here the result

When the Cat's Away

Warning: X-Rated

I got a phone call from IT Guy informing me that his wife was going to be out of town over night. While I hesitated he informed me that his doctor had given him some little yellow pills. How could I turn down a guarantee like that. I asked my husband if it was okay and he gave me the double thumbs up. I put on some lacey underwear and off I went. I

 slipped into his house under the cover of darkness. He said he was surprised that I came. (Well, that remained to be seen.) After sipping some wine and chatting, things started to get steamy. I felt like a teenager making out on the couch, afraid the parents would walk through the door. So exhillarating. He lead me to the bedroom, locked the door, and started slowly peeling away my clothes with his tongue following behind, titilating the newly exposed flesh. When all that was left was my underwear, he stopped and gazed at me. I think I caught a bit of drool running down his face and a low growling sound like Homer when he sees a doughnut. (Poor guy, his wife probably wears grandma panties and a utility bra.) The last time he saw a gorgeous woman in fancy undies was probably in his Victoria’s Secret mag. (While he was still interested in sex anyways.) The whole body licking finally was focussed on my “lady parts” as he calls it. Again, a few pointers and I was ready to let go of the sluices. He was even prepared with a towel near by. The orgasm cames in waves. Waves of muscle contractions and torrents of sex juices. Afterwards he said he was going to call me Niagara Falls.

After some brief recovery, we laid down next to each other on the bed and started kissing. Sure enough, the little yellow pills had done their job, and there infront of me was a lovely erect penis. Lucky for him, or I would have been out of there. I put him in my mouth and he quivered at every stroke. I knew he couldn’t take much of that and I didn’t want to miss the feeling of him inside of me. I climbed on top of him and slipped him in. It was glorious…electric..heart pounding and panting. I rolled and pulled him on top of me. We made love. Yes, I said made love. We weren’t having sex. It was more than that. I knew that it would be for him, but it surprised me that it was for me. I guess I shouldn’t have been surprised since my body finds his so familiar. As we came, he looked at my soul. The words in my mind were ‘I love you’. I choked the words back. I was not ready for that. I finished my wine and slipped back into the night, home to my sleeping family.

I sat up for awhile reflecting on the evening as well as the entire friendship/relationship. Just a short time ago I was convinced I was going to look for a girlfriend and here I was with a man. It seems that this precludes me from having a woman in my life because afterall, there are only so many hours in a day and I already have a full life.

Controllare con il vostro fornitore di cure mediche prima di iniziare, interrompere o modificare la dose di qualsiasi farmaco.

Little more about Cialis

Cialis is the best and most recommended tablet to correct the Erectile Dysfunction. Erectile dysfunction is nothing but the inability to erect, in other words impotency. It can be due to age, depression, stress or side effects of any of the medicines. When a man is considered to have ED (erectile dysfunction), he is unable to get and maintain an erection that is suitable for penetrative sex. This also includes having problems with erection for ending sexual activities. Nearly all men have problems with erection from time to time.

Cialis is recommended by the physicians as well. This dysfunction is prevalent in men of all age groups. Cialis maintains erection strong enough for sexual intercourse. Cialis is one of the cheap drugs which are easily available in the market. It enhances the blood circulation in the penis and in turn results in a long lasting erection. It is a widely used medicine, so you need not think much over it, as this is the best way to get over this problem. But first and foremost you must consult your doctor about the problem. Cialis works for most of the cases. It may take time to show results, but it will for sure show the results to your satisfaction. Buy Cialis as per the prescription and understand the function. The dosage of the drug is recommended by the physician based on your body requirement. It’s important to understand the functionality of the drug so that you are mentally prepared as well.

Cialis has proven to cure the disorder. It’s suggested to take a pill daily for better and stable performance. So try Cialis once and see the difference, it surely will give you an increased level confidence and pleasure in your sexual life. Cialis is one of the cheap drugs with most positive results.
