Cozaar (losartan), a medication drug that has proven successful in treating hypertension (commonly referred to as high blood pressure), may also help improve another condition that plagues older men.

For adults with high blood pressure, many blood pressure medications can decrease sexual appetite and function, and it is for this reason that many adults choose to forego taking such drugs. Understanding how Cozaar may be able to help erectile dysfunction may also help adults in the management of their blood pressure.

How Cozaar May Help Erectile Dysfunction

In a study published in the May 2001 issue of the American Journal of Medicine and Science, researchers found that men being treated for hypertension with the drug Cozaar, who also suffer from sexual dysfunction, reported improvement in at least one area of sexuality.

Study About the Effect of Cozaar on ED

The 12-week study of 164 men, all with hypertension, was divided into 2 groups of 82, one group with sexual dysfunction, the other group reported normal sexual functioning. Both groups took losartan in dosages of 50 to 100 milligrams daily for the 12 weeks of the study. In the group of men with sexual dysfunction, 88 percent reported improvement in at least one area of sexual function and 73.7% reported an improved quality of life.

The number of men reporting improvement was at 88% during the study. The number of men involved in the study who reported impotence dropped from 75.3 % to 11.8%. The results of this study raise hope for men who have quit taking other blood pressure medications because they interfered with sexual function. Sexual dysfunction was defined for the study as decreased libido, impotence and poor sexual satisfaction.

The study group of men without sexual dysfunction, the drug did not produce changes in sexual function or satisfaction.

What That Means for the Future of Sexual Dysfunction

While scientists caution that the results are not definitive, they do point out the need for a larger clinical study. Hypertensive men who are also impotent but who are well controlled on another drug should not be switched to this drug until further study is done.

Carlos Ferrario M.D. states the results of the study also points to the finding that hypertensive drugs do not cause erectile dysfunction, but is, in fact, a part of the disease process itself. He feels that the major contributor to impotence in hypotensive men is angiotensin.

Most cases of sexual dysfunction are related to a physical cause. The most common causes are diabetes, heart disease, neurological trauma or disease, and side effects of medications. Stress and anxiety can also contribute to impotence. While most of the focus has been on men with erectile dysfunction, a number of women also suffer from this disorder.

Exact numbers of suffers are not known as many people do not report these problems to their physicians due to shame. Over the last few years, there have been many exciting advances in the knowledge and treatment of erectile dysfunction, with the most prominent being nanotechnology and endovascular treatments.

Bottom Line

Keeping diseases such as diabetes and hypertension under control will go far in preventing sexual dysfunction, but communication with your physician if it occurs, can help all seniors, male or female, enjoy a healthy and fulfilling sex life.
