In the first clinical trial of the erectile dysfunction drugs Viagra and Cialis, it was found that men who took the drug for more than a year had a more stable improvement compared to those who did not take the drugs.
In the second clinical trial, Viagra's side-effects were similar to those seen with the other erectile dysfunction drugs, but the differences were not as pronounced as in the first trial.
The study, in which a group of 20 men who took Viagra for six months were asked to complete a questionnaire, found that men who took the drug had a significantly lower incidence of erectile dysfunction compared to those who did not take the drug.
Researchers from the University of Newcastle reported that the drugs improved erections in a similar way to the drugs in other trials.
“This may not be a revolution in the treatment of erectile dysfunction, but it is an important finding in the field of clinical pharmacology,” Dr David M. Wilson, an endocrinologist and head of the department of endocrinology at Newcastle Urology, said in a press release.
The study was funded by Pfizer, a San Francisco-based drug company.
The study was published in the British Medical Journal (BMJ) in February 2018.
The researchers looked at data from the six-month follow-up of the trials and compared the results of the two drugs. The other two drugs were also similar in their effect on erectile function.
The drugs were found to improve the erectile function of men who were not taking any of the other erectile dysfunction drugs, according to the journal. A similar study was also published in the British Medical Journal in March in the British Medical Journal.
Dr Wilson said he believed the results of the two trials could be attributed to the differences in the study population, which was based on a different group of men.
The authors of the two trials used the same sample size, which is what led to their results.
“We conducted our own study to examine the effects of Viagra on the erectile dysfunction in the UK. This trial showed that Viagra does not have a significant effect on erectile function,” the authors said.
Viagra, which was introduced in 1998, was the first of a new class of drugs that had been developed to treat erectile dysfunction, which is a common condition that affects millions of men.
The other new class of drugs, Cialis, also works in a similar way to Viagra but has fewer side-effects, according to the journal. Cialis is also available in different doses and has a lower risk of side-effects than Viagra.
The researchers compared the side-effects between the drugs to see how well they were tolerable.
Both the drugs were taken at the same time, and both had similar side-effects, the researchers said.
“The side-effects of the drugs are similar to those seen with the other drugs, and we cannot conclude that Cialis is the most effective,” the study authors said.
However, the authors suggested that the drugs’ side-effects would continue to be more pronounced after a year of treatment, with the drugs likely to have a greater impact on the men.
“These results were also similar to those seen with Viagra or Cialis, but there are still a small number of patients who have benefited from these drugs, and that is a problem,” the authors said.
In the study, the researchers were unable to show a difference in erectile function between the drugs, according to the journal. They recommended that patients start taking the drugs again after a year of treatment.
“There are many reasons why some men may be unable to maintain an erection, and therefore the treatment of choice is to try the drug for a longer period of time,” the researchers said.
They suggested that the drugs’ side-effects might still be more pronounced if patients started taking the drugs on an empty stomach and continued taking them after a meal.
The study was funded by Pfizer, the world's biggest drugmaker and the UK's biggest generic pharmaceutical company.
