Men who have ever had a problem of erectile dysfunction are familiar with medications that stimulate erection. Nearly every one knows that drugs of this group mechanically cause sustained erection. Indeed, stimulants are composed of complex chemical substances which create a relaxing effect on the smooth muscles of the cavernous bodies of the penis, thus stimulating active blood supply.
Viagra is the first and one of the most popular erection stimulating drug on the market. Its main chemically synthesized active component is 1-[4-ethoxy-3-(6,7-dihydro-1-methyl-
7-oxo-3-propyl-1H-pyrazolo[4,3-d]pyrimidin-5-yl)phenylsulfonyl]-4-methylpiperazine. Initially this chemical compound was developed by scientists to improve blood flow to the myocardium (heart muscle) in order to help decrease blood pressure. However, clinical trails haven’t shown the expected results but it was found that men taking this drug experienced substantial blood flow to the genitals. Several years later this medication entered the market under the brand name Viagra. It was positioned as the drug aimed to fix problems with poor erection. As far as it was the only medication for ED at that time, it got the reputation of the fastest-selling drug generating nearly $2 billion from sales worldwide.
But now there is a number of analogical medications on offer and Cialis is one of them. It contains the same active ingredient (sildenafil), which creates absolutely identical effect as Viagra. Cialis should be taken about an hour before having sex and not more than once a day. Remember that Cialis as well as other erection stimulating drugs do not increase libido, so proper sexual stimulation is required to get the maximum pleasure. But there is one distinctive feature of Cialis that makes it stand out among other ED pills – it can be taken on a daily basis in smaller doses. Unlike Viagra or any other drugs Cialis can be prescribed for a daily use for ED treatment depending on the severity of the disease. So there is a choice for a man: either to use Cialis once right before intercourse or to take it daily.
Since Cialis is being sold for many years already, there are lots of reviews of men whose sexual health has been restored due to these pills. One can easily find them online on men’s forums where they share their experience of taking Cialis. You can also order the medication via online pharmacies without a need to leave your house. The best thing of buying Cialis online is that you can do it without prescription, though it’s always recommended to visit your doctor before starting to take any medication.
