Cialis gaining on Viagra
Cialis, the so called ‘weekend pill’ is overtaking Viagra as the erection pill of choice, according to an article in Psychology Today.
Recent studies show Cialis has overtaken Viagra as the number one prescription drug in Europe. Eli Lilly the company who produces Cialis also claims the drug has overtaken Viagra in sales in the U.S, though this is disputed by Pfizer who make Viagra.
In 2007 Viagra controlled 62% of the U.S. market, with Cialis at 26% and Levitra at 12% though it’s thought Cialis and Levitra have since increased in popularity.
What is Cialis?
Like Viagra and Levitra, Cialis is a pill used to treat erectile dysfunction but it is effective for a longer period of time, up to 36 hours, earning it the nickname ‘the weekend pill’. Like the others it is prescribed on an ‘as needed’ basis but is also the only of the three that can be prescribed to be taken regularly; often men will take low doses of the pill on a daily basis. It should be taken at least 30 minutes before sexual activity.
It is based on an inhibitor called Tadalafil which improves the flow of blood to the penis. The pills are yellow tear drop shapes and smaller than Viagra’s well-known blue pill.
Cialis is the newest of the erectile dysfunction treatments. It was licensed in November 2003. (Levitra was licensed in August 2003 and Viagra in March 1998). Cialis comes in 5 mg, 10 mg, and 20 mg tablets. Most men start out using 10 mg tablets and either increase or decrease the dosage depending on effectiveness.
Viagra and Levitra
Viagra and Levitra are also based on inhibitors that increase the blood flow to the penis, sildenafil and vardenafil respectively. Although different in appearance; Viagra is a blue diamond shape and levitra is round and yellow, both are similar and the effects of the erection tablets last on average four hours, though some studies suggest some benefit for up to 10 hours. It is recommended that those prescribed Viagra or Levitra take it half an hour to an hour before sexual activity.
Viagra comes in 25mg, 50mg, and 100mg tablets, with most men starting on the 50mg pill and changing doseage if necessary.
Levitra comes in 2.5mg, 5mg, 10mg, and 20mg pills. Levitra should be taken anywhere from 25 minutes to 1 hour prior to sexual activity, although some experts claim it is the fastest acting of the erectile dysfunction treatments and can be taken effectively as little as 15 minutes before sexual activity.
With its long lasting effect it is perhaps unsurprising that Cialis is surging in popularity. Surveys of men who’ve tried a range of erection treatments apparently confirm this.
According to Pyschology Today there have been eight separate studies that have compared Viagra and Cialis. In the studies each drug was used between 2 to 6 months and at the end of the period couples were asked which of the drugs they preferred. The consistent response was that couples preferred Cialis.
Another study, but which was funded by the makers of Cialis, found that men said they preferred their erection after taking Cialis compared to other drugs used to treat erectile dysfunction.
Success and side-effects
The drugs work in around 70% of men and have similar side effects. They have the potential to cause headaches, flushing, runny noses, stomach aches or even changes in vision. Doctors say these are common and should not be a reason to worry. None of the three drugs should be taken with blood pressure medication or nitrates, including amyl nitrate (Poppers).
