Rock hard erections can be easily attained with the help of the erectile dysfunction (ED) drugs. The first erectile dysfunction drug came into the market in 1998. The drug was named as the Viagra and was invented by the Pfizer. This drug was very expensive because of its on growing demand. Only the rich people were able to buy the Viagra because of its high price. Viagra was still out of the reach of the common man. Hence, the revolution took place and arrived to the market the generic Version of Viagra, called as the Kamagra. Kamagra is an oral medication that markedly improves sexual activity in over 80% of men with erectile dysfunction. Kamagra contained sildenafil citrate as the active constituent similarly like the original Viagra and in the same concentration. Kamagra enables many men with ED to respond to sexual stimulation.

When a man is sexually aroused, sildenafil citrate, salt of Kamagra allows the arteries in the penis to relax and expand, allowing more blood to flow into the penis. Hence men are able to get the hard erection. Kamagra also expand and harden arteries in the penis, and simultaneously reduce the flow of blood outside the penis allowing the men to hold the hard erection for long duration during the sexual copulation. After Viagra a new drug came to market know as Cialis that allowed the men to hold the erection for the long time than Viagra. Men were able to enjoy multiple erections for the duration of 20 to 24 hours with the help of Cialis. Thus, the cheaper version of Cialis called as Tadalis came to the market that also contained Tadalafil as the active constituent. Then the next to invent was Levitra that contained Vardenafil as the active constituent that was used to make possible the rock hard erections.

It is said that age has nothing to do with the sex, but it is true that sex is affected adversely by the age. Men above the age of 40 usually fail to have the erection during the sexual encounter and fail to satisfy their partner. The condition gets worse as the erection becomes very rare and soft as the age increases. Hence, all these men suffer from the erectile dysfunction, a condition in which men are unable to get the erection or hold the erection for the sufficient amount of time during the sexual intercourse. Thus, all the men who are having the problems with erection can use the drugs known as erectile dysfunction drugs and treat the erection problems. Yes, with the help of erectile dysfunction drugs like Kamagra, Tadalis, and generic Levitra rock hard erections are possible.

After seeing the success of Kamagra, many other generic version of Viagra came to the market. Caverta, Zenegra, Edegra are few other names of the generic versions of Viagra.

Headache, blurred vision, diarrhea are some of the side effects that are temporary and go off as your body gets used to the dosage of the drug. Food and Drug Administration has approved all these generic version of erectile dysfunction drugs. The main reason for the loss of erection is the less amount of blood supply to the penis during the sexual activity. ED drugs increases the blood supply to the male reproductive system and treats the impotence problems. With the single dose of the ED drugs men can attaind the rock hard erections for the long time during the sexual activity.
