What is the History of Cialis? 

Cialis is a popular erectile dysfunction drug used to treat symptoms of male sexual dysfunction. This drug was funded by the large pharmaceutical company Glaxo Wellcome, which is now known as GlaxoSmithKline. Generic Cialis (tadalafil) was invented in the late ’90s, around the same time as other erectile dysfunction drugs like Viagra and generic Viagra.

At the beginning of 1991, chemists at Glaxo Wellcome began developing a drug that could assist in erectile dysfunction. By 1994, Pfizer scientists discovered a phosphodiesterase type 5 (PDE 5) inhibitor to assist in ED. PDE 5 inhibitors are primarily used for male sexual dysfunction problems and work by blocking the action of the phosphodiesterase type 5 substance. [1]

These new findings found that the Cialis prototype also boosts a chemical called nitric oxide. This allows the muscles in the penis to relax easier, which is an essential function because the penile muscles must be relaxed for blood to flow into the penis when sexual stimulation is present.

Clinical trials for tadalafil (the generic name for Cialis) began in 1997. Several years and many trials later, Cialis was approved by the Food and Drug Administration in 2002 and was launched on the international pharmaceutical market. From there, Cialis has become nearly as popular as its predecessor, Viagra. In 2007, Eli Lilly acquired all the rights to Cialis and became the drug's sole manufacturer and distributor. [2]

How Common is ED? 

Cialis has been prescribed hundreds of millions of times since it hit the market, but how often is this medication needed? ED is often related to age, but it is not a normal part of the aging process. As older generations continue to age and experience ED, ED medications' prevalence will continue to increase. Over 100 million people in the United States are over 50 years old, so Cialis will continue to be a staple in the pharmaceutical world. [3] 

Aging is not the reason for ED, but the older men become, the more likely they are to have conditions that increase their risk for sexual dysfunction. These conditions include diabetes, high cholesterol, and high blood pressure.

The Massachusetts Male Aging Study found that 52 percent of men experience some form of ED, which increases as men grow older. The Journal of Sexual Medicine also cites that 26 percent of men under 40 years old experience ED symptoms. Generic Cialis, as well as brand-name, may be prescribed for men of all ages. [4]

Cialis Usage & Dosage

Many people prefer Cialis over other erectile dysfunction drugs because of their longevity and potency. As mentioned above, Cialis is a PDE 5 inhibitor that increases the blood flow to the penis. Cialis relaxes the muscles of the penis and allows blood to fill the penis for sexual intercourse.

You can buy Cialis online through Canadian Med Center in 2.5, 5, 10, and 20-milligram dosages. This drug has many different dosages because it is approved for daily use, unlike other ED drugs like Viagra. Along with assisting in ED symptoms, the FDA approved the use of Cialis for enlarged prostate. An enlarged prostate (benign prostatic hyperplasia) can cause ED as well as many unpleasant urinary symptoms. [1]

Along with increasing the blood flow to the penis, another chemical in Cialis called cyclic guanosine monophosphate relaxes the bladder and prostate, easing urinary symptoms. If you have benign prostatic hyperplasia, you may be prescribed five milligrams of Cialis per day to improve urinary and ED symptoms.

How Long Does Cialis Last?

If you are not taking Cialis every day to assist in prostate issues or chronic ED problems, you will want to take this drug around 30 minutes before sexual activity. The big difference between Cialis and other ED drugs is that Cialis lasts much longer. Cialis can last for 36 hours after taking it, so you do not have to take it every time before sexual activity.

If you take a smaller dose like 2.5 mg, Cialis will constantly be in your system, meaning that your body will always be ready for sexual activity. If you have an erection that lasts longer than four hours, you may want emergency medical help. This condition is known as priapism and causes persistent and painful erections.
