This paper investigates if the highly selective norepinephrine reuptake inhibitor reboxetine leads to a dose-dependent cortisol release and if this response depends on personality dimensions related to clinical depression in healthy volunteers. Twenty-four male subjects received placebo, 2 mg, or 4 mg reboxetine in a balanced, randomized cross-over study. Cortisol was measured in saliva at six different time-points according to the kinetics of the drug. Furthermore, several measurements of cardiovascular parameters, emotional states, and possible side-effects were obtained. Subjects were divided into two groups scoring above or below the median of a depressiveness questionnaire scale [n = 11, low (D-); n = 13, high (D+)]. Results clearly demonstrated, that reboxetine stimulates cortisol release. Whereas blood pressure was not affected, heart rate increased after 2 and 4 mg but not dose dependently. Subjects reported more non-specific arousal while the dimensions of tiredness-wakefulness and positive-negative emotional states were not affected by the drug. Somatic complaints were low and only non-specific complaints were statistically elevated but of negligible amount. Subjects classified as D+ can be characterized as high responders to the drug. This is especially true not only for cortisol increases but also for changes in heart rate and some ratings on physical complaints. Hot flushes, sweating and a throbbing sensation in blood vessels in the head were observed in D+ but only with the 4 mg dose. The results clearly demonstrate that reboxetine stimulates cortisol release and heart rate and that this is particularly pronounced in subjects scoring high on depression-related personality dimensions. Reboxetine, therefore, is a promising tool for investigating neuroendocrine response to noradrenergic challenge tests. The question whether increased responses in D+ are due to an up-regulation of receptor sensitivity as a consequence of low norepinephrine supply is discussed.

Goserelin acetate is a LH-RH agonist developed by AstraZeneca (formerly ICI, UK), and has been used clinically for the treatment of prostate cancer as a 4-week controlled-release formulation (Zoladex 3.6 mg depot). Recently, a new drug (Zoladex LA 10.8 mg depot) with 3-month controlled-release formulation was developed and became commercially available in Japan. In the randomized comparative phase III studies carried out with global bases, single administration of the new drug yielded almost equivalent anti-testosterone effect and the same serum level of the previous 3.6 mg depot formulation in 3-times continuous administration. In these studies, adverse drug reactions, which were mainly due to pharmacological effects of the new drug and minimal, were found in 52.6% (41/78) compared with 54.8% (46/84) with the previous 3.6 mg depot formulation. In the phase III studies, there were no significant differences in average serum testosterone levels between the two formulations at 12 and 13 weeks after administration. In the Japanese late phase II study with untreated patients, castration effect was observed in all 20 cases entered in the trial. In 20 cases in which treatment was switched from 3.6 mg depot to the new formulation, there were no significant changes in serum testosterone levels at castration level of the untreated patients, 90% (18/20) responded to the treatment, and normalization of PSA level was found in 75.0% (15/20). The adverse drug reactions were mainly increased triglyceride level and hot flushes. In the retrospective evaluation of untreated patients in this trial and the post-marketing clinical trial data for 3.6 mg depot, it was concluded that the new drug had almost the same efficacy and safety profile as 3.6 mg depot in Japanese people. These results indicate that Zoladex LA 10.8 mg depot has the same efficacy and safety as 3.6 mg depot with administration every three months, the burden of injection of LH-RH agonist can be reduced. This new medication can be considered a new standard for treatment of prostate cancer.

In our studies of the development of a novel class of selective estrogen receptor modulators, (+)-3-[4-(1-piperidinoethoxy)phenyl]spiro[indene-1,1'-indane]-5,5'-diol hydrochloride (1) was found to be an estrogen receptor ligand with beneficial effects in rat models for human hot flush. Moreover, 1 was found to have beneficial effects on lipid and bone metabolism while maintaining marginal effects on the uterus and breasts. These findings suggest that 1 would provide a new treatment for hot flush.

More than 1 million women are expected to reach menopause each year, many of whom will experience hot flushes and other neuropsychological symptoms that may diminish their quality of life. Hot flushes are the core symptoms that reflect the brain's response to the changing hormonal milieu of the menopause transition, particularly to the rapidly fluctuating and falling levels of estradiol. The physical symptoms of hot flushes and the associated changes in sleep, mood, and cognition will lead many women to seek medical care. It is critical to understand the interrelationship of hot flushes and other neuropsychological symptoms of the menopause transition so that treatment priorities can be established. For example, if sleep disruption explains most daytime neuropsychological problems in women with hot flushes, treating insomnia should be considered a priority. Alternatively, mood, cognition, and quality of life may be disturbed independent of sleep problems. In such a situation, each symptom should be evaluated separately from any assessment of sleep. As recent data from the WHI establish the risks of long-term HRT use, concern about using HRT, even as a short-term intervention, has increased substantially. Although HRT remains the first-line treatment for hot flushes, the WHI findings have drawn attention to nonhormonal treatments of hot flushes and other menopausal symptoms. Growing evidence to support the efficacy of serotonergic antidepressants and other psychoactive medications in the treatment for hot flushes suggests that nonhormonal interventions will prove important alternatives to HRT. As further evidence of the benefits of psychoactive medications for menopausal symptoms is established, the choice between using hormonal and nonhormonal therapies for management of menopausal symptoms will continue to evolve.

Menopause is a process, either naturally or medically induced, that occurs in nearly all women at some point in life. Some of the most commonly reported symptoms associated with menopause are hot flushes/flashes, fatigue, headaches, irritability, insomnia, and depression. These symptoms overlap with symptoms commonly reported in Traumatic Brain Injury (TBI) as well as postconcussive syndrome. This overlap between symptoms commonly associated with menopause and neuropsychological conditions makes it necessary to have the base rates of these symptoms and conditions available. The purpose of the present review was to consolidate the clinical literature on the most commonly reported menopausal symptoms and to calculate the base rates associated with these symptoms.

That gonadal steroids influence the limbic system and that they affect neurotransmitter activity is undisputed. Because of these known actions, and because ET and HT alleviate hot flushes and resultant sleep disturbances, they may improve mood and sense of well-being in healthy climacteric women. However, estrogen plus progestin did not decrease depressive symptoms in the WHI, the largest double-blind, placebo-controlled trial of hormone replacement yet performed. In addition, although several studies have suggested efficacy in this regard, neither ET nor HT has been proved to be therapeutic for major depression in perimenopausal and menopausal women. Certainly, further studies are needed on the potential of estrogen as an antidepressant. Based on current evidence, however, one cannot prescribe ET or HT as primary treatment for major depression in good conscience. When treating patients far this serious problem, one cannot rely on theory and the desire that it be borne out. As Sigmund Freud wrote: "Thus we call a belief an illusion when a wish-fulfillment is a prominent factor in its motivation, and in doing so we disregard its relation to reality, just as the illusion itself set, no store by verification". Since the initial publication of the results of the WHI, clinicians have learned to be cautious when making decisions about therapy that has not been proved in randomized controlled trials. In addition, attention has shifted away from potential global effects of ET and HT toward more specific management of each specific clinical sequela of menopause. If major depression is to be addressed in this way, SSRIs become first-line therapy, with TCAs considered second-line because of reduced tolerability. ET and HT may be added separately as appropriate, and may be helpful on an individual basis. Indeed, treatment for major depression in any person, male or female, at any age, is best chosen based on life situation and the neuropsychology of the condition, and not based on gender alone.

ATAC, a randomized, double-blind trial, compared tamoxifen (20 mg) with anastrozole ('Arimidex') (1 mg) alone, and the combination of anastrozole plus tamoxifen (combination), as adjuvant endocrine treatment for postmenopausal patients with early breast cancer. Patients with operable invasive breast cancer following completion of primary therapy, who were candidates to receive adjuvant endocrine therapy, were eligible for this study. Primary endpoints were disease-free survival (DFS) and tolerability. Other endpoints included time to recurrence (TTR: censoring non-breast cancer deaths before recurrence) and the incidence of contralateral breast cancer. A total of 9366 patients were included in this study (N=3125, 3116 and 3125 for anastrozole, tamoxifen and the combination, respectively). Median duration of therapy was 30.7 months and median follow-up was 33.3 months. The total numbers of events were 317, 379 and 383 for anastrozole, tamoxifen and the combination, respectively. DFS was significantly improved in the overall population for anastrozole versus tamoxifen (hazard ratio (HR)=0.81, 95% confidence interval (CI) (0.71-0.96), P=0.013). Anastrozole showed improved TTR compared with tamoxifen (HR=0.79, CI (0.67-0.94), P=0.008), which improved even further in the ER+ and/or PR+ subgroup (HR=0.73, CI (0.59-0.90), P=0.003). The incidences of hot flushes, thromboembolic events, ischaemic cerebrovascular events, vaginal bleeding/discharge and endometrial cancer were significantly reduced with anastrozole compared with tamoxifen (P<0.03 for all). Musculoskeletal disorders and fractures were significantly reduced in patients receiving tamoxifen compared with those on anastrozole (P<0.03 for both). No increase in hip fractures was seen for anastrozole versus tamoxifen (11 versus 13, respectively). Combination treatment was equivalent to tamoxifen in terms of both efficacy and tolerability. Anastrozole showed superior efficacy to tamoxifen for DFS, TTR and contralateral breast cancer. Early findings show anastrozole to be an effective and well-tolerated endocrine option for the treatment of postmenopausal patients with early breast cancer. For the first time a choice now exists for adjuvant endocrine treatment for postmenopausal women with hormone responsive tumours. Longer follow-up will further define the benefit/risk of anastrozole adjuvant therapy.

Conventional oestrogen-based hormone therapy (HT) increases the incidence of breast pain and tenderness, mammographic density and the risk of breast cancer. Combined oestrogen plus progestogen therapy (EPT) increases the risk of breast cancer to a greater degree than oestrogen alone (ET). Attention must therefore be focused on identifying women at risk of breast cancer or on producing a HT that has fewer breast side effects. Randomised controlled trials have shown that while EPT induces breast tenderness or pain in up to 50% of women and increases mammographic density in up to 70% during the first year of treatment, only about as many as one-tenth women report breast tenderness or pain with tibolone and increases in mammographic density are rare, occurring with a similar incidence as seen in untreated controls. Many women with breast cancer suffer vasomotor symptoms rather than risk recurrence with conventional HT. However, in a small randomised controlled trial in women with early breast cancer undergoing adjuvant tamoxifen treatment, tibolone reduced hot flushes, night sweats and improved quality of life compared with placebo.

The aim of the present study was to develop an experimental paradigm for the study of serotonergic neurotransmission in humans using positron emission tomography and the 5-HT2A selective radioligand [18F]altanserin. [18F]altanserin studies were conducted in seven subjects using the bolus/infusion approach designed for attaining steady state in blood and brain 2 hours after the initial [18F]altanserin administration. Three hours after commencement of radiotracer administration, 0.25 mg/kg of the selective serotonin reuptake inhibitor, citalopram (Lundbeck, Valby, Denmark), was administered to all subjects as a constant infusion for 20 minutes. To reduce 5-HT1A-mediated autoinhibition of cortical 5-HT release, four of the seven subjects were pretreated with the partial 5-HT1A agonist pindolol for 3 days at an increasing oral dose (25 mg on the day of scanning). In each subject, the baseline condition (120 to 180 minutes) was compared with the stimulated condition (195 to 300 minutes). Despite a pronounced increase in plasma prolactin and two subjects reporting hot flushes compatible with an 5-HT-induced adverse effect, cortical [18F]altanserin binding was insensitive to the citalopram challenge, even after pindolol pretreatment. The biochemical and cellular events possibly affecting the unsuccessful translation of the citalopram/pindolol challenge into a change in 5-HT2A receptor binding of [18F]altanserin are discussed.

Breast cancer is one of the main life-threatening diseases that a woman may have to face during her lifetime. The increasing incidence of breast neoplasia reported over the last few decades has led to widespread screening of women resulting in early diagnosis. One common but challenging question for most doctors, after the surgical excision of the lesion, is determination of the ideal adjuvant therapy for their patients for the achievement of maximum life expectancy with the best quality of life. Since the beginning of the last century, the knowledge that breast cancer arises from hormone-responsive tissues has long made use of hormone-blocking agents in the beneficial treatment of breast neoplasia. The discovery of new molecules with endocrine actions has rendered the use of adjuvant therapy in a tailor-made pattern too complicated, as these agents have a different mode of action, different adverse effects and probably different indications. The aim of the present review is to clarify these issues, analyzing the mechanism of action of available drugs and their actions on specific areas of uncertainty: cognitive function, cardiovascular system, urogenital tract, bone metabolism, weight gain, hot flushes and premature menopause. Regarding the efficacy of adjuvant therapy, there has been particular focus on the multiple hormonal-induced consequences of each regimen in order to provide the clinician with the available data for choosing the ideal therapy for the patient.
