So what is the legendary blue pill with Sildenafil like?
History of Kamagra
Sildenafil was synthesized by a group of chemists who worked at a Pfizer company research center in Sandwich, Kent County (England). Initially, the substance was created to treat hypertension or angina pectoris, but during the first phase of clinical tests, the scientists discovered that the drug acts little on ischemia, but is capable of creating a little known, penis erection. Eventually, the Pfizer company decided to introduce it to the market, not as a drug that treats angina pectoris, but as a therapy in the absence of male strength.
Kamagra was patented in 1996 and approved by the FDA for use on March 27, 1998  . Once supplied in pharmacies all over the world, it immediately became a great success. The first week 247 666 recipes were prescribed. The second week, the number of customers grew to over 50,000. Eventually, in 1998, the company “Pfizer” sold Kamagra for $ 1 billion! Annual sales peaked in 2008 at US $ 1.934 billion.
Over time Kamagra has seen its analogues come out on the market, such as Kamagra Professional , Kamagra Super Active , however, nowadays it still remains the most requested means in case of absence of erection and allows men to receive maximum enjoyment during intimate intercourse.
How the drug works
Kamagra is used to treat the symptoms of erectile dysfunction, which can be caused by a number of factors: starting with psychological trauma, stress and ending with prostatitis or diabetes.
Kamagra is not a hormonal means, a means of arousal or aphrodisiac, which allows most patients to use it every day .
The task of this drug is to relax the back muscles, normalize and increase the flow of blood in the penis, and in particular in the corpus cavernosum. It takes place in the following way: Sildenafil, the active ingredient of Kamagra, is an inhibitor (suppresses) the ferment of phosphodiesterase 5, which prevents normal opening of vessels. In other words, Kamagra widens the vessels in the penis, bringing blood inside. The penis increases in size and hardens .
The blue pill containing Sildenafil, should be taken 40-60 minutes before the scheduled sexual act. The duration of the effect is between 4 and 6 hours. In relation to the individual peculiarities of the organism, the duration of the effect can be somewhat varied  .
In addition to the treatment of erectile dysfunction, the drug is effective during the treatment of pulmonary hypertension and altitude sickness .
Composition of Kamagra
The medicine is produced in the form of pills, covered with a blue film. It has a biconvex rhombus shape, with cut and rounded corners. There is Pfizer inscription on one side and VGR 100 on the other, which proves the concentration of the active ingredient Sildenafil equal to 100 mg.
The composition of Kamagra 100 mg also includes several auxiliary substances: microcrystalline cellulose, calcium hydrogen phosphate, croscarmellose sodium, magnesium stearate .
It is better to start the administration with the 50 mg dosage.

In relation to the effect received and the state of health, the dosage can be increased up to 100 mg or decreased up to 25 mg  .
