(ED) patients are a confused lot these days. For a change, this is a welcome confusion. It is a problem of plenty. From the days of no oral treatment to variety of drugs on display, millions of impotent patients are relishing the attention.

showed the way to drug developers when a chance discovery made them realize that Sildenafil Citrate, that was used for the past two decades for treating Angina, was in fact, a much better option for ED treatment. It enhanced blood flow in the male sexual organ and helps in achieving an erection that sufficiently satisfies the opposite partner. All that was required to do was pop the pill about half-an-hour prior to the intended act. Since Viagra is a prescription drug, the authorities prescribe restraint from buying Viagra online. Viagra ruled the ED drug-market for about 5 years virtually monopolistically.

The year 2003 saw the maturing of ED-drug-market with Levitra and Cialis posing a tough challenge to the Numero Uno Viagra. However, captured the imagination of the world like never before, thus proving to be the toughest competitor to Viagra till date. The USP of Cialis is the duration for which this drug stays in the body. One pill will ensure you 36 hours of blissful moments! This is precisely the reason for the French to call it ?the weekender?.

And now, few words of caution.

Cialis is a prescription pill and must never be purchased OTC, even if offered. The physical examination of patient is vital before prescribing Cialis. That's why online pharmacies selling Cialis online are looked down upon.

Like any other drug, Cialis also has few minor side effects, like nausea, gastric problems etc. But these side effects are not common rather an exception to the rule. Cialis is otherwise a safe drug. However, one must desist from drug abuse as the use of Cialis just for thrills may prove to be injurious for health.
