Viagra (Sildenafil Citrate)

Viagra (Sildenafil Citrate)
Viagra
Viagra is a drug that is given to men with certain sexual problems in order to help them to have sexual intercourse. Viagra relaxes muscles found in the walls of blood vessels and increases blood flow to particular areas of the body.
The basic ingredient of the medicine is selective inhibitor of phosphodiesterase of 5th type of Sildenafil citrate. This substance relaxes smooth muscles of cavernous bodies of a penis and strengthens blood circulation in it. This causes erection. Useful properties of the active substance related to impotence therapy were revealed accidentally.

In 1992 in England scientists developed a new medicine against coronary heart disease on basis of Sildenafil. However the substance didn’t strengthen blood circulation in the heart. However, one very interesting “collateral” effect was found in Sildenafil – it improved blood circulation in a penis and caused erection.

After some further researches Sildenafil was patented under the Viagra trademark and in 1998 was put on the market. Originally only the Pfizer company possessed the patent for Viagra production, but after its validity period expired many companies began to propose analogs of the drug. They have practically the same efficiency as the original as all ingredients remained the same.

Original Viagra was produced in the form of diamond-shaped tablets with bluish-blue color an an inscription “Pfizer” on the one side, and with the figures corresponding to a dosage in mg (VGR 25, 50 or 100) on the other side. Analogs of this remedy are available in the form of tablets, capsules and even gel.

INTERACTION WITH ALCOHOL

An intake with alcohol can load dangerously heart and vessels.

Another dangerous effect is massive allergic reaction. There are no exact data about how the simultaneous intake of alcohol and this medicine affects your health. An individual intolerance can cause an unpredictable allergy.

VIAGRA REVIEWS

Lora7986: I am probably the first one among my friends who writes a review on Viagra Online. But after all the demand for feedback is very high and I want to share my story. Me and my husband have been together for nearly 8 years, our intimate relations are excellent, but continuous advertizing on TV haunted me. They always show a man at age and 3 women around him. I asked my husband to buy Viagra, but he always was against it.

One day, when we had a holiday and there was a favourable situaton for that, I have persuaded the husband to buy the pills. Now I want to describe everything consequently: a packing with 4 tablets costs 50 dollars, there are 3 types of the medicine, with a dosage of 100 mg, 50 mg and 25 mg. In the drugstore the personnel explained us that if the man has no potency at all and he wants good erection it’s necessary to buy 100 mg, etc. We have bought 25 mg, in a packing with 4 small tablets, blue color, without any smell. The was an instruction attached where everything is described, where I also have read that one tablet produces the effect for 12 hours and for a man it will be enough! Still the important note is that if the man takes Generic Viagra too often, his organism will get used and won’t be able to function properly without these tablets.

My husband drunk one tablet and at once he told me that he has strong head ache… an hour later… ((, and two hours later there was no result. Well in the evening we had a magic according to our plan, however it was as usual during the previous 8 years)). Then I also had terrible head aches.

And now I can tell with confidence that no men and women should spend this money for 4 tablets after which your head hurts so much and there is no result at all. I’m home again and I watch advertizing during a movie about these tablets and how delighted they are with its effect and I don’t understand anymore, if there is any real result at all or just the imagination of the people who produce and buy these tablets!

I don’t advise to spend money for Generic Viagra Online, it doesn’t make anything special, except a wild headache.

Eva: Sometimes my husband has failures with sex. Probably because of the high level of cholesterol. They are on sale in various packings. There are blisters with 1, 2, 4 and on 12 pieces. Who doesn’t need this medicine really often, can buy just one tablet for testing. It’s very convenient. But the more tablets you buy, the more favorable it is. My husband takes one pill (50 mg) an hour before the intimate contact. At the right time everything happens, and abates safely within a certain period of time.

I want to discredit one myth about Generic Viagra. They say that if you take the medicine then the erection will come and last long enough. It’s not true. The erection comes just with some sexual excitement. That is why if your object of passion is absent, nothing happens.

Jaremy_46: I am 34 years old. We lived 7 years with my wife, she is 6 years older than me, we satisfy each other in the bed, but I decided to make a surprise on her next birthday and bought Viagra. Everything was good, the birthday party with candles and all the necessary romantic staff. I have taken the medicine as specified in the instruction, presumably an hour before. The moment of truth has come.

Everything started and at first it was okay. After a short break we repeated the procedure and this time it went wrong. My heart began to beat as if I run an olympic marathon. The pulse began to raise and in about ten minutes I got insufferable head aches!!! There was such a feeling that blood begins to boil! We finished and I went to take a shower and nearly fainted. I hardly crawled to bed, I got a pill of analginum and instantly fell asleep. In the morning everything was normal, but I can’t forget that state when it seems that your heart stops the next moment!!! But I wouldn’t like to die at such moment. Generally I won’t repeat this dangerous experiment anymore. In my opinion, if everything is normal, then you shouldn’t try this medicine and if there are problems you have to go to the doctor.

Zina_T: I welcome all who have decided to read my feedback. We decided to try the tablet just for kicks. I bought one tablet of 25 mg in a drugstore. A small dose of at least 50 mg was necessary. Generally the erection was as usual, we could feel some side effects like skin burning and reddening, I haven’t noticed anything else. I consider that the price of this medicine is overstated and don’t expect a great miracle. Perhaps I will continue the experiment with 50 mg or 100 mg dose, for now I advise to drink sour milk and honey with walnuts to make less harm to your organism.
