Cialis vs Viagra

Viagra was a revolutionary drug when it first came out in the mid-90s. After all, it was the first of its kind, a medicine that was finally created after years of research and experimentation. Although it was first studied as a cure for hypertension, its effects were more marked in the area of penile erections. Because of this Sildenafil, marketed as Viagra by Pfizer, became a drug for erectile dysfunction, the first that enables impotent men to have an erection due to sexual stimulation rather than an automatic result of medication. This effect has something to do with the arterial walls in the penile muscle -- it has a component that controls the substance in the penis that makes blood circulation in the organ difficult. However, due to its success, other companies followed suit in attempts to copy Pfizer's success. Lilly ICOS LLC developed Cialis while Bayer developed Levitra.

What makes Cialis different from Viagra? There are very few distinctions between the two drugs: both have the same side effects and both have the same restrictions. Cialis can also cause common side effects like flushing and headaches and it can also cause severe and life-threatening side effects. It also does not go well with certain medications; specifically, HIV drugs. The reason for the side effects when combing Cialis and HIV drugs is the same with Viagra -- HIV drugs have components that can prolong the effects of Cialis, making the user more vulnerable to its side effects. The dosage restrictions in Cialis is the same with Viagra, too -- people over 65 years of age are advised to take low dosages or are advised not to take the drug at all.

The main difference could be the strength of the medicine. Cialis is said to have a longer half-life -- 17.50 hours compared to Viagra's five. The effects of Cialis are also faster -- it takes 30 minutes after use to make erection possible with Cialis, compared to the one hour and thirty minutes of Viagra. In more crass terms, many online sources say Cialis is more appropriate for "sexual marathons" while Viagra is for more intimate sexual intercourse.

But there may be some little differences that are not yet noted. After all, if the effects of Cialis last longer, it should also mean that its side effects could be more pronounced than Viagra. For instance, there are some rare reports that Cialis has caused damage to the penile tissue of few users, a side effect that can cause to permanent impotence. There were also rare reports of sudden hearing loss as another side effect of using Cialis. This is a case unheard in Viagra usage. Therefore, there could be other side effects one drug has that the other doesn't.

How can one decide what medicine to buy? This could be a matter of preference, although further research on the topic could help buyers decide. One should consider that Viagra has been in the market the longest; hence it is the most trusted and perhaps the most refined. One could say that since Cialis is new, it uses a technology alien to Viagra. In any case, one should simply research and, if possible, see for themselves what works better for their bodies.
