The hot flush is the only symptom specifically attributable to the menopause. Hot flushes appear to represent an episodic derangement of thermoregulation as a result of estrogen deficiency but the underlying physiological mechanisms are unknown. We have developed an animal model for the study of hot flushes. Two female monkeys (Macaca arctoides) were trained to accept monitoring of scalp cutaneous temperatures. After baseline temperature recordings were obtained both monkeys were ovariectomized. A few days after operation the previously stable scalp temperature changed to an undulating pattern with cycles lasting approximately 40-50 min. Ethinyl estradiol (20 micrograms orally or im) and (7 alpha,17 alpha)-17-hydroxy-7-methyl-19-nor-pregn-5(10)-en-20-yn-3-one (2.5 mg orally), a steroid with weak estrogenic, progestogenic, and androgenic properties, suppressed the characteristic undulating temperature pattern; this returned after withdrawal of replacement therapy. Clonidine (0.15 mg twice a day) suppressed the cyclic changes for 2 to 3 h. Domperidone and naloxone had no significant effect. This animal model may be useful for the investigation of alternative therapy for the management of menopausal flushes.

A growing body of evidence suggests that antidepressant therapies, particularly selective serotonin reuptake inhibitors and venlafaxine, are effective in the management of hot flash symptoms. Several of these agents have the support of the American College of Obstetricians and Gynecologists and the North American Menopause Society. To review the literature on antidepressants for the treatment of hot flashes in women, we searched the PubMed, International Pharmaceutical Abstracts, and MEDLINE databases from inception through May 2009. All publication types that included human participants and that were published in English were eligible for review. These articles, relevant abstracts, and additional references were used to collect pertinent data. Although initial small pilot trials were conducted solely in breast cancer survivors, additional studies have been conducted both in breast cancer survivors and in relatively healthy menopausal women. Data on the benefits with many of these agents are conflicting. Venlafaxine and paroxetine have been studied more extensively than any of the other antidepressants and are more consistent in effectively reducing the frequency and severity of hot flashes, based on these study results. Desvenlafaxine, sertraline, fluoxetine, and citalopram should be considered second- or third-line options if patients fail therapy with or cannot tolerate venlafaxine or paroxetine, based on the current published data. Duloxetine, escitalopram, fluvoxamine, and mirtazapine should be reserved as last-line therapy until more rigorous studies are conducted assessing their use in the management of hot flashes.
