Asthma is more common in young women after they begin having periods, and hospitalizations due to asthma is higher among women than men. The severity of asthma also varies during a woman’s menstrual cycle and when she is pregnant. But studies show that asthma generally wanes after menopause.

Estrogen-only HRT has already been linked to uterine cancer in women who still had their uteruses, but the combined therapy was deemed safer for women who had not undergone a hysterectomy. Once thought to be a cure-all for not only menopausal symptoms but also for cancer and heart disease, the estrogen-plus-progestin HRT became a billion-dollar industry in the late 20th Century. But in 2002, a large-scale federal study found that women who took the combined HRT were at greater risk of breast cancer and heart disease. Since 2002, HRT use among women has dropped significantly.

There is a mad dash among pharmaceutical companies worldwide to find a drug that safely treats the symptoms of menopause. Premarin, after all, was the best selling HRT in the U.S. before the Women’s Health Initiative (WHI) in 2002 linked HRT to higher incidences of breast cancer, heart attacks and strokes. Since then, the use of HRT has drastically reduced, and similarly, so has the incidence of breast cancer among menopausal women.

Despite the urgency in finding a safer alternative to HRT, experts say it will take at least four years for the synthetic hormones to become available. And it would expensive. Drugs for human use typically cost about $1 billion to develop. The next step would be finding an effective way to communicate to women that the synthetic hormones are actually safe, a tough job considering the bad rap HRT has received since WHI.
