Doesnt Work for Women The hot-selling impotence drug Viagra may do wonders for men, but a new study shows it's not so effective in women. Researchers led by urologist Steven A. Kaplan of Columbia-Presbyterian Medical Center in New York studied 33 post-menopausal women who reported suffering sexual dysfunction for at least six months. Their complaints included low sex drive, arousal problems, diminished lubrication and lack of or difficulty in achieving orgasm. After 12 weeks of taking Viagra, about a quarter of the women reported some improvement in sexual function, but Kaplan says it's unclear whether their improvement was caused by the placebo effect, in which the act of taking a pill brings improvement in symptoms. Researchers reported that Viagra was successful in increasing blood flow to the clitoris and increasing lubrication, but that did not appear to lead to sexual satisfaction. Seven women complained the drug made the clitoris overly sensitive, causing discomfort during intercourse. The drug is already prescribed for some women. According to Viagra manufacturer Pfizer, about 8 million prescriptions have been issued. Viagra was approved last March and became the fastest-selling drug on the market. Sales worldwide totaled $788 million by the end of 1998. Researchers point out this study is small and needs to be replicated with larger groups of women. The study appears in the March issue of Urology. |
