The present article reviews direct and indirect evidence of the effects of sex steroids on different aspects of sleep. It begins with a review of what is known about the effects of steroid hormones on sleep and on central nervous system processes related to sleep, such as the GABA-ergic system, in animals. It continues with a review of the effects of exogenous hormones on human sleep and a review of studies comparing sleep during hypogonadal states secondary to surgical or natural menopause. The article proceeds to review the data on the effects of the menstrual cycle on both subjective and objective aspects of sleep and circadian temperature and melatonin rhythms in samples of healthy women, women with premenstrual dysphoric disorder, and women with primary insomnia. Then, the article reviews gender differences in sleep during depression and raises the possibility that sex steroids moderate these differences. Finally, the article concludes with a discussion of the implications of the data reviewed for basic clinical, and methodological aspects of sleep research.

Selective serotonin-reuptake inhibitors (SSRIs), including fluoxetine, sertraline, paroxetine, fluvoxamine, and citalopram, represent an important advance in the pharmacotherapy of mood and other disorders. They are chemically unrelated to tricyclic, heterocyclic, and other first-generation antidepressants. SSRIs are the treatment of choice for many indications, including major depression, dysthymia, panic disorder, obsessive-compulsive disorder, eating disorders, and premenstrual dysphoric disorder, because of their efficacy, good side-effect profile, tolerability, and safety in overdose, as well as patient compliance. A review of the literature was conducted using Medline and the terms "SSRIs," "fluoxetine," "sertraline," "paroxetine," "fluvoxamine," and "citalopram." Articles were limited to those published in English within the last 15 years. The search revealed that indications for antidepressants include unipolar depression, dysthymia, bipolar depression, treatment-resistant depression, depression in the medically ill, panic disorder, obsessive-compulsive disorder, eating disorders, social phobia, and premenstrual dysphoric disorder. One SSRI, fluoxetine, has demonstrated safety in pregnancy. Side effects of SSRIs include gastrointestinal disturbances, headache, sedation, insomnia, activation, weight gain, impaired memory, excessive perspiration, paresthesia, and sexual dysfunction.

Since the introduction of antidepressants in the 1950s, it was assumed for the next several decades that there were no special reasons to look at the application of these medications to women. In the past half-century, particularly in the past decade, since the advent of the selective serotonin re-uptake inhibitors (SSRI), a series of specific foci have developed. Firstly, there appear to be differences in the degree of response to particular antidepressants between the genders. Secondly, there is data concerning hormonal effects of particular relevance to women, i.e. prolactin, which separates out among the antidepressants. Also of concern to women are the potential teratogenic effects of these medications, which impact on their use during pregnancy. Finally, there are certain diagnostic syndromes that are particularly relevant to women: premenstrual dysphoric disorder (PMDD); postpartum depression (PPD) and perimenopausal depression (PMD). It appears that the SSRIs may be more effective, relative to the older tricyclic antidepressants (TCA), in women than in men. The SSRIs have shown to be effective in treating these disorders, with the possibility of intermittent luteal phase treatment of PMDD. Non-antidepressant (AD) approaches have generally been found to be less effective. In the first trimester of pregnancy, there is data available supporting the safe use of SSRIs, particularly those first released, i.e. fluoxetine and sertraline. Finally, all SSRIs, with the exception of sertraline, can increase the risk of hyperprolactinaemia. This can lead to a variety of complications including amenorrhea and osteoporosis. This effect of sertraline, due to its unique profile in blocking re-uptake of dopamine, extends itself into additional relative benefits for sleep and memory. The issues associated for women with bipolar disorder are dealt with in terms of both increased risk of relapse during pregnancy and postpartum periods, as well as the relative risk of use of lithium and mood stabilizers in pregnancy and lactation.

Sertraline (Zoloft, Pfizer) has been shown in numerous controlled studies to have similar efficacy to other selective serotonin (5-HT) re-uptake inhibitors (SSRIs) in the treatment of depression and anxiety disorders. Further research is indicating that the efficacy of sertraline extends even beyond the treatment of depression and anxiety to include utility in eating disorders, premenstrual dysphoric disorder (PMDD) and possibly substance abuse treatment. Along with other SSRIs, sertraline offers several advantages over older antidepressants, including improved patient tolerability, low risk of lethality in overdose and no dependence potential. In head-to-head comparisons, sertraline appears to be at least as well-tolerated as other SSRIs and may even have a more favourable side effect profile. Low potential for pharmacokinetic drug interactions is another advantage of sertraline. Unlike fluoxetine, fluvoxamine and paroxetine, sertraline is not a potent inhibitor of any of the cytochrome P450 isoenzyme systems. As a result of its proven efficacy, good tolerability and lack of pharmacokinetic interactions, sertraline should be considered first-line in the treatment of anxiety and depressive disorders.

Changes in serotonergic parameters have been reported in psychiatric conditions such as depression but also in the premenstrual dysphoric disorder (PMDD). In addition, hormonal effects on serotonergic activity have been established. In the present study, binding of [3H]paroxetine to platelet serotonin uptake sites and binding of [3H]lysergic acid diethylamide ([3H]LSD) to platelet serotonin (5-HT)2A receptors were studied in patients with PMDD treated with a low dose of a gonadotropin releasing hormone (GnRH) agonist (buserelin) or placebo and compared to controls. The PMDD patients were relieved of premenstrual symptoms like depression and irritability during buserelin treatment. The number of [3H]paroxetine binding sites (Bmax) were significantly higher in the follicular phase in untreated PMDD patients compared to controls. When treated with buserelin the difference disappeared. No differences in [3H]LSD binding between the three groups were shown. The present study demonstrated altered platelet [3H]paroxetine binding characteristics in women with PMDD compared to controls. Furthermore, [3H]paroxetine binding was affected by PMDD treatment with a low dose of buserelin. The results are consistent with the hypothesis that changes in serotonergic transmission could be a trait in the premenstrual dysphoric disorder.

The naphthylamine derivative sertraline is a potent and selective inhibitor of serotonin reuptake into presynaptic terminals. Sertraline has a linear pharmacokinetic profile and a half-life of about 26 h. Its major metabolite, desmethylsertraline does not appear to inhibit serotonin reuptake. Sertraline mildly inhibits the CYP2D6 isoform of the cytochrome P450 system but has little effect on CYP1A2, CYP3A3/4, CYP2C9, or CYP2C19. It is, however, highly protein bound and may alter blood levels of other highly protein bound agents. Sertraline is a widely used serotonin reuptake inhibitor that has been shown to have both antidepressant and antianxiety effects. Many clinical trials have demonstrated its efficacy in depression compared with both placebo and other antidepressant drugs. Its efficacy has also been demonstrated in randomized, controlled trials of patients with obsessive-compulsive disorder, panic disorder, social phobia, and premenstrual dysphoric disorder. In short-term, open-label studies it has appeared efficacious and tolerable in children and adolescents and in the elderly, and data are positive for its use in pregnant or lactating women. Typical side effects include gastrointestinal and central nervous system effects as well as treatment-emergent sexual dysfunction; withdrawal reactions may be associated with abrupt discontinuation of the agent. The safety profile of sertraline in overdose is very favorable. Sertraline's efficacy for both mood and anxiety disorders, relatively weak effect on the cytochrome P450 system, and tolerability profile and safety in overdose are factors that contribute to make it a first-line agent for treatment in both primary and tertiary care settings.

Paroxetine is a potent and selective serotonin reuptake inhibitor (SSRI) with currently approved indications for the treatment of depression, obsessive-compulsive disorder, panic disorder and social phobia. It is also used in the treatment of generalized anxiety disorder, post traumatic stress disorder, premenstrual dysphoric disorder and chronic headache. Paroxetine, a phenylpiperidine derivative, is the most potent inhibitor of the reuptake of serotonin (5-hydroxytryptamine, 5-HT) of all the currently available antidepressants including the class of SSRIs. It is a very weak inhibitor of norepinephrine (NE) uptake but it is still more potent at this site than the other SSRIs. The selectivity of paroxetine, i.e., the ratio of inhibition of uptake of norepinephrine to serotonin (NE/5-HT) is amongst the highest of the SSRIs. Paroxetine has little affinity for catecholaminergic, dopaminergic or histaminergic systems and by comparison with tricyclic antidepressants (TCAs) has, therefore, a reduced propensity to cause central and autonomic side effects. Paroxetine exhibits some affinity for the muscarinic cholinergic receptor but much less than the TCAs. In addition, the adaptive changes of somatodendritic (5-HT(1A)) and terminal (5-HT(1B/1D)) autoreceptors observed with paroxetine are different to those observed with TCAs; it also inhibits nitric oxide synthase. It is both a substrate and an inhibitor of cytochrome isoenzyme P450 2D6. Paroxetine is well absorbed orally and undergoes extensive first pass metabolism that is partially saturable. Its metabolites are pharmacologically inactive in vivo. Steady state levels are achieved after 4-14 days and an elimination half-life of 21 h is consistent with once-daily dosing. There is wide inter-individual variation in the pharmacokinetics of paroxetine in adults as well as in the young and the elderly with higher plasma concentrations and slower elimination noted in the latter. Elimination is also reduced in severe renal and hepatic impairment. Serious adverse events are, however, extremely rare even in overdose. In summary, paroxetine is well tolerated and effective in the treatment of both depressive and anxiety disorders across the age range.

Premenstrual dysphoric disorder (PMDD) is a severe form of premenstrual syndrome (PMS). This is the first trial of a unique oral contraceptive containing a combination of drospirenone (DRSP, 3 mg) and ethinyl estradiol (EE, 30 microg) for the treatment of PMDD. DRSP is a spironolactone-like progestin with antiandrogenic and antimineralocorticoid activity. Spironolactone has been shown to be beneficial in PMS, whereas oral contraceptives have shown conflicting results. In this double-blind, placebo-controlled trial, 82 women with PMDD (Diagnostic and Statistical Manual of Mental Disorders, 4th ed. [DSM IV]) were randomized to receive DRSP/EE or placebo for three treatment cycles. The primary end point was change from baseline in luteal phase symptom scores as assessed on the Calendar of Premenstrual Experiences (COPE) scale. Patients treated with DRSP/EE showed a numerically greater change from baseline compared with those treated with placebo on each of the 22 COPE items and each of the 4 symptom factors. Between-group differences in symptom improvement reached statistical significance in factor 3 only (appetite, acne, and food cravings, p = 0.027). The secondary end points, Beck Depression Inventory (BDI) and Profile of Mood States (PMS), were consistent with the primary end point in that patients treated with the oral contraceptive showed a numerically greater improvement from baseline compared with those treated with placebo. The results of this study show a consistent trend in the reduction of symptoms that suggested a beneficial effect of DRSP/EE for the treatment of PMDD, despite limitations of the study design.

Depression is more common in women than in men, particularly during the childbearing years. Women may present with different depressive symptoms than men and may respond differently to antidepressant treatment. In addition, depression in women can surface in association with specific points in the reproductive cycle, such as during the premenstrual period, during pregnancy and the postpartum period, and during the perimenopausal years. Antidepressant medications may be used effectively at all stages in a woman's life. In the case of premenstrual dysphoric disorder, serotonergic agents have demonstrated efficacy in both full-cycle and luteal-phase dosing strategies. For depressed women who are pregnant or breastfeeding, the limited safety data available on antidepressants suggest minimal danger to the fetus or infant, and the risks and benefits to both mother and child must be weighed against the risks of untreated illness. Treatment of depression in middle-aged and elderly women should take into account the possible influence of both menopausal status and hormone replacement therapy on antidepressant response. This article will focus on special considerations in the evaluation and management of depression in women across the life span.

Women have twice the incidence of major depression compared with men. They are prone to develop episodes of depression during times of reproductive hormonal change at puberty, with use of oral contraceptives, during the premenstrual phase of the menstrual cycle, postpartum and during the perimenopause (see review: ). describes the variety of disturbances in biological rhythms observed in mood disorders. In this report, we describe the chronobiological disturbances observed in female-specific mood disorders, namely, premenstrual dysphoric disorder, pregnancy and postpartum depression and menopause. We hypothesize that changing reproductive hormones, by affecting the synchrony or coherence between components of the circadian system, may alter amplitude or phase (timing) relationships and thereby contribute to the development of mood disorders in predisposed individuals.
