There are other drugs that are used for erectile dysfunction Cialis isn’t the only one. Cialis is the only one which is the long acting erectile dysfunction drug produced by Lilly ICOS. The other drug companies are Pfizer, Abbott Laboratories, and Bayer all of whom have produced treatments for impotence problems in men as well. However, in studies Cialis appears to be preferred by many.

Viagra was the original breakthrough treatment for impotence in men, produced in the USA by Pfizer. The medication works in a similar way to Cialis, by relaxing the blood vessels in the penis, thus allowing blood to flow in, enlarge and become erect. The medication Viagra usually takes effect after about 15 minutes and will normally last for up to 4 hours. Because the erection is immediate sex has to be planned. And many couples felt that this made the erection seem chemically induced.

Abbot Laboratories manufactures Uprima and is a medication that contains Apomorphine, a drug which is associated with neurological problems. By acting on sensors in the brain Uprima enhances the libido to stimulate sexual arousal. The medication Uprima is a fast acting product and is absorbed under the tongue therefore passing into the bloodstream quickly. This is particularly useful if you have difficulty swallowing. One of the complaints with this drug is that it doesn’t last as long and it has been know to cause some harsher side effects.

The Bayer organization produces the impotence medication Levitra which works to alleviate impotence in men in a similar way to both Cialis and Viagra. The pill is available in three dose sizes and the medication acts in about an hour and sexual stimulation is required. Many have an issue with this medication as it can take as long as an hour to begin working. The problem with this and other penile dysfunction medications is that couples complain about having to “plan” sex. Cialis not only begins to work quickly but continues through out more then a day allowing for there to be a feeling of spontaneity. Many who suffer the problem of impotence believe this to be important.

Many of the other drugs such as Uprima report side effects that can be quite uncomfortable such as cramping and headaches and there have been reported side effects with the others. In a few cases Cialis patients did experience some mild side effects but these seem few in number.
