The Search for the Female Equivalent of Viagra

Even in the most sexually liberated and self-satisfied of nations, many people still yearn to burn more, to feel ready for bedding no matter what the clock says and to desire their partner of 23 years as much as they did when their love was brand new. The market is saturated with books on how to revive a flagging libido or spice up monotonous sex, and sex therapists say “lack of desire” is one of the most common complaints they hear from patients, particularly women. And though there may be legitimate sociological or personal underpinnings to that diminished desire — chronic overwork and stress, a hostile workplace, a slovenly or unsupportive spouse — still the age-old search continues for a simple chemical fix, Cupid encapsulated, a thrill in a pill. Since the spectacular success of Viagra and similar drugs, the pharmaceutical industry has been searching for the female equivalent of Viagra — a treatment that would do for women’s most common sexual complaint, lack of desire, what sildenafil did for men’s, erectile dysfunction. Initial trials of Viagra in women proved highly disappointing. True, the drug enhanced engorgement of vaginal tissue, just as it had of the penis, but that extra bit of pelvic swelling did nothing to amplify women’s desire for or enjoyment of sex. What is needed for the treatment of so-called female hypoactive sexual desire disorder, researchers decided, is a reasonably safe and effective drug that acts on the central nervous system, on the pleasure centers of the brain or the sensory circuitry that serves them.

VITAL SIGNS; Viagra May Benefit Some Women

Most research shows that Viagra, while effective in treating erectile dysfunction in men, does not help women with sexual arousal or enjoyment. But a new study suggests that the drug could help certain women -- those who suffer the sexual side effects of antidepressants -- to achieve an orgasm. Pfizer, which makes Viagra, financed the study, which appears in the current issue of The Journal of the American Medical Association. The researchers compared the effects of Viagra with a placebo in an eight-week study of 98 women who reported at least a month of sexual dysfunction from taking antidepressants. They found that 72 percent of the women who took Viagra reported overall sexual improvement in a questionnaire that takes into account arousal, enjoyment and orgasm; 27 percent of those taking the placebo reported such gains. During the study, women taking Viagra suffered headaches and indigestion at a higher rate than women taking the placebo. The average age of the women in the study was 37, and none had entered menopause. Initial endocrine levels did not differ significantly between the groups, and the women agreed to try to have sex at least once a week. Previous studies, including those financed by Pfizer, have not shown that Viagra works for women.

Starting with an already available drug has meant "the safety of this is well-defined and understood," Dr. Yeager said. So NexMed just needed to know whether the same drug could increase blood flow to women's sexual organs, too. "In female anatomy, it dilates the blood vessels that feed the labia," Dr. Yeager said, "and these are highly proliferated with secretory cells, and you need increased blood flow for increased secretion and increased engorgement." "The idea was," he added, "would the prostaglandins, if properly delivered, increase vasodilation so you go through the cascade of events that lead to excitement and orgasm?" The newly patented formula contains prostaglandin E.sub.1, as well as a thickener, an acid buffer to balance pH and prevent skin irritation, and an agent to enhance absorption into the skin. It can be mixed into a cream, lotion or gel. "We want to keep the dose low for safety, but we want rapid penetration into the tissue, because if you want to apply it, you don't want to wait forever for it to work," Dr. Yeager said. He said women should need wait only five or 10 minutes for a dab of the cream to take effect. "Of course, they'll need to engage in some sexual activity," he added. Dr. Yeager and two colleagues, Nadir Buyuktimkin and Servet Buyuktimkin, received Patent 6,486,207.

That is the case in the patent awarded to NexMed Inc. , a pharmaceutical and medical technology company in Robbinsville, N.J. It won a patent last fall for a cream based on a drug already used in pellets and shots to treat erectile dysfunction. Dr. James L. Yeager, the NexMed senior vice president for scientific affairs, said Food and Drug Administration approval of the cream was "at least three years away." As with men, the companies are trying to treat a breakdown in the body's physical reaction to sexual stimulation. The NexMed patent points out that men and women typically experience four sexual stages that include "desire, excitement, orgasm and resolution." The cream for women is designed to help those whose bodies do not trigger an increase in blood flow to sexual organs that is necessary for the excitement stage. In its patent, the inventors define female sexual arousal disorder as the persistent or recurrent inability to attain, or to maintain, sufficient sexual excitement, which causes personal distress. "Arousal disorder is definitely something you see in postmenopausal women due to lack of hormones," Dr. Yeager explained. "But it's also present in premenopausal women. The typical woman in our study was premenopausal, married, with one to two children, between 35 and 40 years old." "These women say they can have intercourse, but nothing happens, they don't get aroused," he continued. "We don't know why. We think it has something to do with the action of vasodilation, or blood vessel dilation, gone awry. It's not psychological." The patented cream uses the same active ingredient in the shots and pellets for men, a chemical compound called prostaglandin. The patent describes the compound as "derivatives of certain unsaturated fatty acids." Prostaglandin is found in the body, where it stimulates smooth muscles in the intestines and respiratory system, as well as in the reproductive system. One compound, called prostaglandin E.sub.1, has been used to treat heart disease, strokes, ulcers and organ rejection, the patent says, and it notes that prostaglandin has also been used specifically for women before ? for inducing labor, controlling postpartum bleeding, even for terminating pregnancy.

A Female Counterpart to Viagra

VIAGRA, the drug that used professional athletes and a retired senator to become a household word, may soon have a counterpart for women. A pharmaceutical company has patented a topical cream as a treatment for a condition it calls female sexual arousal disorder. If sexual dysfunction among women does not yet have a universal name, it is because the phenomenon has only recently caught the attention of the medical establishment. The elimination of taboos on male impotence, and the economic success of Viagra, have helped with that. Now most pharmaceutical companies see a huge potential market for drugs for women, and are racing to develop them. In 1999, The Journal of the American Medical Association reported that 43 percent of women between 18 and 54 had experienced some sort of sexual dysfunction. That number includes women with known physical ailments that can affect sexual function, like heart disease or hormone imbalances. In fact, part of the problem for researchers is reaching a definition of female sexual dysfunction ? but they are eager to do so because some anticipate a $6-billion-a-year market. Still, it may be several years before treatments for women appear on drugstore shelves. A lot of the research starts with remedies that have worked for men.

PDE-5 Inhibitor Sildenafil Improves Cognition, or Viagra's Obedient as a replacement for the Big Fully Too

Inspired sooner than Speed Limbaugh's apparent erectile dysfunction, I unquestionable that today's Nasty Newspaper Blackjack should address the "other" quiescent uses of PDE-5 inhibitors, the most (in)well-known of which is Viagra. Phosphodiesterase type 5 (PDE-5) is an enzyme that breaks down cyclic GMP. We've known on the side of a while that cGMP is powerful in place of signal transduction and done for culture and recollection processes, and that nitric oxide (NO) can encourage production of cGMP. Interestingly, changes in this NO-cGMP signaling pathway comprise been implicated in aging, providing a aptitude component to deteriorating cognition with increased age.

PDE-5 inhibitors such as sildenafil citrate (Viagra) may consequently dissimulation to improve cognition via preventing the enzyme PDE-5 from breaking down cGMP. The paper in scrutiny today sought to check this admissibility opportunity through first demonstrating that recall effectuation could be impaired before administration of a drug called L-NAME, which blocks NO shaping about disrupting the enterprise of the enzyme nitric oxide synthase (NOS). Nearby blocking NOS, L-NAME decreases the amount of NO, which last analysis decreases levels of cGMP and produces cognitive impairment.
