Transfer of anticonvulsants and lithium into amniotic fluid, umbilical cord blood & breast milk: A systematic review & combined analysis. Prog Neuropsychopharmacol Biol Psychiatry 2023; 124:110733. [PMID: 36805301 DOI: 10.1016/j.pnpbp.2023.110733] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/06/2022] [Revised: 01/21/2023] [Accepted: 02/10/2023] [Indexed: 02/17/2023]
Abstract
OBJECTIVE Data on the ability of anticonvulsants and lithium to enter fetal and newborn circulation has become increasingly available; here we estimated penetration ratios in a series of matrices from combined samples of pregnant/breastfeeding women treated with anticonvulsants or lithium. METHODS We conducted a systematic literature search in PubMed/EMBASE for studies with concentrations of anticonvulsants/lithium from maternal blood, amniotic fluid, umbilical cord blood and/or breast milk. Penetration ratios were calculated by dividing the concentrations in amniotic fluid, umbilical cord plasma or breast milk by the maternal concentrations. When data from multiple studies were available, we calculated combined penetration ratios, weighting studies' mean by study size. RESULTS Ninety-one eligible studies for brivaracetam, carbamazepine, clonazepam, ethosuximide, gabapentin, lacosamide, lamotrigine, levetiracetam, lithium, oxcarbazepine, perampanel, phenobarbital, phenytoin, pregabalin, primidone, topiramate, valproate, vigabatrin and zonisamide were identified. For amniotic fluid, the highest penetration ratios were estimated for levetiracetam (mean 3.56, range 1.27-5.85, n = 2) and lowest for valproate (mean 0.11, range 0.02-1.02, n = 57). For umbilical cord plasma, oxcarbazepine had the highest ratio (mean 1.59, range 0.11-4.33, n = 12) with clonazepam having the lowest (mean 0.55, range 0.52-0.59, n = 2). For breast milk, the highest ratios were observed for oxcarbazepine (mean 3.75, range 0.5-7.0, n = 2), whereas the lowest were observed for valproate (mean 0.04, range 0.01-0.22, n = 121). DISCUSSION We observed substantial variability between anticonvulsants and lithium regarding their ability to enter fetal/newborn circulation. Assessing concentrations of anticonvulsants and lithium in maternal samples can provide a surrogate of fetal/infant exposure, although patterns of concentration-dependent effects for maternal/neonatal safety are lacking.

Psychotropic medication in pregnancy and lactation and early development of exposed children. Br J Clin Pharmacol 2023; 89:737-750.

Abstract
There is still limited knowledge about alterations of blood concentrations of psychotropic drugs during pregnancy, the transfer of psychotropic drugs into breastmilk and the effects on exposed children. We investigated changes in concentrations of psychopharmacological medication during pregnancy and lactation in serum and breastmilk at different time points in a naturalistic sample of 60 mothers and observed the development of the exposed children in the first 12 months. We found a decrease in serum concentrations from the first to the second trimester of amitriptyline, duloxetine, escitalopram, quetiapine and sertraline. Citalopram stayed rather stable during pregnancy, sertraline levels interestingly increased again from the second to the third trimester. High concentration-by-dose ratios in breastmilk were found for venlafaxine as well as lamotrigine, low for quetiapine and clomipramine. Similarly, clomipramine and quetiapine showed low milk/serum-penetration ratios. Regarding the birth outcome measures in children, we found no significant differences between in utero exposed compared to nonexposed newborns. There were no significant differences in the development in the first 12 months. Psychotropic medication in the peripartum needs a balancing of risks and benefits and a continuous therapeutic drug monitoring can be a guidance for clinicians to monitor drug alteration patterns, which are likely to occur due to physiological pregnancy-associated changes in pharmacokinetics. Accordingly, therapeutic drug monitoring can optimize a medication in pregnancy and lactation with the lowest effective dose.

Abstract
OBJECTIVE Data regarding the ability of antidepressants to enter fetal, newborn and infant fluids have become gradually available, but mechanisms of antidepressant transfer remain poorly understood. Here we calculated penetration ratios in an array of matrices from combined samples of pregnant/breastfeeding women taking antidepressants. METHOD We performed a systematic literature search of PubMed and EMBASE to identify studies with concentrations of antidepressants from maternal blood, amniotic fluid, umbilical cord blood and/or breast milk. Penetration ratios were calculated by dividing the concentrations in amniotic fluid, umbilical cord plasma or breast milk by the maternal plasma concentration. When data from multiple studies were available, we calculated combined penetration ratios, weighting the study mean by study size. RESULTS Eighty-five eligible studies were identified. For amniotic fluid, the highest penetration ratios were estimated for venlafaxine (mean 2.77, range 0.43-4.70 for the active moiety) and citalopram (mean 2.03, range 0.35-6.97), while the lowest ratios were for fluvoxamine (mean 0.10) and fluoxetine (mean 0.11, range 0.02-0.20 for the active moiety). For umbilical cord plasma, nortriptyline had the highest ratio (mean 2.97, range 0.25-26.43) followed by bupropion (mean 1.14, range 0.3-5.08). For breast milk, the highest ratios were observed for venlafaxine (mean 2.59, range 0.85-4.85), mianserin (mean 2.22, range 0.80-3.64) and escitalopram (mean 2.19, range 1.68-3.00). CONCLUSION We observed considerable variability across antidepressants regarding their ability to enter fetal, newborn and infant fluids. Measuring antidepressant concentrations in a maternal blood sample can provide a reliable estimate of fetal/infant exposure, although further evidence for concentration-dependent effects is required.

Abstract
The selective serotonin reuptake inhibitors (SSRIs) are the most extensively studied of the newer antidepressants and are increasingly being used as first-line treatment for depression (Anderson et al, 2000). In this article we concentrate on issues that need to be taken into account when selecting one of the five SSRIs marketed in the UK (citalopram, fluoxetine, fluvoxamine, paroxetine and sertraline) for individual patients. We have concentrated on treatment of depression and have not reviewed their use in anxiety disorders because comparative data are lacking.

Abstract
There is much evidence from clinical trials that antidepressants help prevent relapse and recurrence of major depression. However, this is unlikely to hold true for all patients with depression, particularly those treated in primary care. Individual antidepressants are equally efficacious, so choice (as first-line treatment in general or for individual patients) is largely determined by differences in side-effects, even though many of these disappear during long-term treatment, owing to adaptation. Specific effects that are considered in choosing a drug include those on cognition, psychomotor performance and sexual function; drug interactions, lethality in overdose and the potential for teratogenicity are also considered. There are insufficient entirely objective and generally accepted data on pharmaco-economics to allow for confident recommendations on drug choice for long-term treatment. Drug acquisition costs must be considered by those with restricted budgets, and especially patients in developing countries where difference in cost between newer and older drugs can be translated into more food for a hungry family.

Abstract
Adverse effects of psychotropic medication on breast-fed infants have not been studied in controlled and systematic research. Existing information comes from small case series and single case reports. These limited data confirm that psychotropics are excreted into breast milk and that the infant is exposed to them. In recent decades sufficient data have accumulated to allow psychiatrists to prescribe tricyclic antidepressants, selective serotonin reuptake inhibitors, conventional antipsychotics, carbamazepine and sodium valproate to breast-feeding mothers with safety. There are not sufficient data on atypical antipsychotics to allow women to breast-feed safely. Mothers on clozapine or lithium should not breast-feed. It is good practice to recommend that breast-feeding mothers requiring psychotropic medication be on a low dose of one single drug. Future research taking account of maternal mental health, psychopharmacological factors, infant physiological environment and individualised risk/benefit assessment will yield clearer responses to this complex issue.

Abstract
Objective:To provide a guide for practicing pharmacists, pharmacy technicians, and other healthcare professionals so that they are able to counsel and advise breast-feeding mothers and fellow healthcare professionals on the safety and use of antiinfectives, vaccines, antiepileptics, benzodiazepines, psychotherapeutic drugs, and radiopharmaceuticals during breast-feeding.Data Sources:Primary texts used by the breast-feeding community ( Medications and Mothers' Milk, Drugs in Pregnancy and Lactation, Drugs and Human Lactation) were searched, as well as Micromedex, MEDLINE, PubMed, EMBASE, and EMBASE2 (1984–February 2004).Study Selection/Data Extraction:Multiple sources were used wherever available to validate the data, and primary articles were used to verify all tertiary source information. Search terms included breast-feeding, lactation, nursing, and medications, as well as specific drug names.Data Synthesis:Concerns regarding medication use during breast-feeding have caused mothers to either discontinue nursing or not take necessary medications. Complete avoidance of medications or cessation of breast-feeding is often unnecessary. Although there are drugs that can be harmful to nursing infants, breast-milk concentrations of most drugs are insufficient to cause any harm.Conclusions:Having objective and reliable information on medications enables pharmacists, pharmacy technicians, other healthcare providers, and mothers to make educated decisions regarding drug therapy and breast-feeding.

Abstract
INTRODUCTION Despite more that 60 years of clinical experience, the effective use of lithium for the treatment of mood disorder, in particular bipolarity, is in danger of becoming obsolete. In part, this is because of exaggerated fears surrounding lithium toxicity, acute and long-term tolerability and the encumbrance of life-long plasma monitoring. Recent research has once again positioned lithium centre stage and amplified the importance of understanding its science and how this translates to clinical practice. OBJECTIVE The aim of this paper is to provide a sound knowledge base as regards the science and practice of lithium therapy. METHOD A comprehensive literature search using electronic databases was conducted along with a detailed review of articles known to the authors pertaining to the use of lithium. Studies were limited to English publications and those dealing with the management of psychiatric disorders in humans. The literature was synthesized and organized according to relevance to clinical practice and understanding. RESULTS Lithium has simple pharmacokinetics that require regular dosing and monitoring. Its mechanisms of action are complex and its effects are multi-faceted, extending beyond mood stability to neuroprotective and anti-suicidal properties. Its use in bipolar disorder is under-appreciated, particularly as it has the best evidence for prophylaxis, qualifying it perhaps as the only true mood stabilizer currently available. In practice, its risks and tolerability are exaggerated and can be readily minimized with knowledge of its clinical profile and judicious application. CONCLUSION Lithium is a safe and effective agent that should, whenever indicated, be used first-line for the treatment of bipolar disorder. A better understanding of its science alongside strategic management of its plasma levels will ensure both wider utility and improved outcomes.

Abstract
Lithium use in mental diseases has changed over the years but remains a cornerstone of treatment in bipolar disorders. In two companion papers, we have reviewed existing (and especially recent) data on lithium efficacy and updated basic knowledge regarding the practical fundamentals of lithium therapy. The present paper reviews safety data on lithium available to date. Gastrointestinal pain or discomfort, diarrhoea, tremor, polyuria, nocturnal urination, weight gain, oedema, flattening of affect and exacerbation of psoriasis are typical complaints of patients receiving long-term lithium therapy. Renal involvement results in a reduced urinary concentrating capacity, expressed as obligate polyuria, with secondary thirst. With long-term therapy, this may result in nephrogenic diabetes insipidus. In addition, glomerular filtration rate falls slightly in about 20% of patients. The view that only a few patients receiving long-term lithium are at increased risk of glomerular impairment and progressive renal insufficiency should be regarded with caution. The risk is increased in case of concomitant diseases or medications. Lithium treatment may inhibit thyroid hormone release and induce goitre. Consequently, the prevalence of both overt and subclinical hypothyroidism is increased, with circulating thyroid auto-antibodies frequently being found. Much less commonly, thyrotoxicosis may also develop in association with lithium therapy. Long-term lithium treatment may also be associated with persistent hyperparathyroidism and hypercalcaemia, as well as with hypermagnesaemia. Overweight of up to 4-10 kg is found in approximately 30% of lithium-treated patients. Most neurological manifestations are benign, for example, the fine postural and/or action tremor present in 4-20% of patients. This is increased by high caffeine consumption and concomitant use of other psychotropic agents. A number of rare, potentially serious neurological adverse effects have been reported, including extrapyramidal symptoms, 'pseudotumour cerebri' or occasionally cerebellar symptoms. Severe neurological sequelae are exceptional. Cognitive disturbances are often mentioned as a lithium-related adverse effect. The few controlled studies do show a statistically significant negative effect of lithium on memory, vigilance, reaction time and tracking. There are frequent reports of mild effects of lithium on cognition at therapeutic serum concentrations. A number of deaths associated with lithium treatment have been reported. The most serious issue is that of non-accidental overdose, i.e. either long-term overdosage or acute overdose on long-term treatment. Progressive renal insufficiency, an exceptional complication of long-term lithium therapy, may also have a fatal outcome. In relation to pregnancy, lithium salts are rated as category D (positive evidence of risk). Therefore, prescription of lithium should be avoided during the first trimester of pregnancy unless the benefit to the mother exceeds the risk to the fetus. Although lithium transfer into breast milk is well established, the long-term fate of babies breast-fed by mothers receiving lithium therapy is unknown. Whether lithium therapy is safe in breast-feeding women is controversial. Although there is no absolute contraindication, it is known that the kidney is particularly sensitive to lithium just after birth. Intoxication in patients on long-term treatment with lithium in the absence of history of acute ingestion is not rare. Contributing factors include change in daily dose, long-term high dosage, kidney disease or drug interaction. In suspected cases, serum concentrations should be obtained early and repeatedly. In addition to supportive measures, haemodialysis is the treatment of choice for severe cases. Thorough knowledge of the limitations and drawbacks of lithium therapy is mandatory for its optimal use, especially at a time when its risk/benefit profile needs to be compared accurately with that of antiepileptic drugs and other mood stabilizing medications.

Abstract
After a single dose, lithium, usually given as carbonate, reaches a peak plasma concentration at 1.0-2.0 hours for standard-release dosage forms, and 4-5 hours for sustained-release forms. Its bioavailability is 80-100%, its total clearance 10-40 mL/min and its elimination half-life is 18-36 hours. Use of the sustained-release formulation results in 30-50% reductions in peak plasma concentrations without major changes in the area under the plasma concentration curve. Lithium distribution to the brain, evaluated using 7Li magnetic resonance spectroscopy, showed brain concentrations to be approximately half those in serum, occasionally increasing to 75-80%. Brain concentrations were weakly correlated with serum concentrations. Lithium is almost exclusively excreted via the kidney as a free ion and lithium clearance is considered to decrease with aging. No gender- or race-related differences in kinetics have been demonstrated. Renal insufficiency is associated with a considerable reduction in renal clearance of lithium and is considered a contraindication to its use, especially if a sodium-poor diet is required. During the last months of pregnancy, lithium clearance increases by 30-50% as a result of an increase in glomerular filtration rate. Lithium also passes freely from maternal plasma into breast milk. Numerous kinetic interactions have been described for lithium, usually involving a decrease in the drug's clearance and therefore increasing its potential toxicity. Clinical pharmacology studies performed in healthy volunteers have investigated a possible effect of lithium on cognitive functions. Most of these studies reported a slight, negative effect on vigilance, alertness, learning and short-term memory after long-term administration only. Because of the narrow therapeutic range of lithium, therapeutic monitoring is the basis for optimal use and administration of this drug. Lithium dosages should be adjusted on the basis of the serum concentration drawn (optimally) 12 hours after the last dose. In patients receiving once-daily administration, the serum concentration at 24 hours should serve as the control value. The efficacy of lithium is clearly dose-dependent and reliably correlates with serum concentrations. It is now generally accepted that concentrations should be maintained between 0.6 and 0.8 mmol/L, although some authors still favour 0.8-1.2 mmol/L. With sustained-release preparations, and because of the later peak of serum lithium concentration, it is advised to keep serum concentrations within the upper range (0.8-1 mmol/L), rather than 0.6-0.8 mmol/L for standard formulations. It is controversial whether a reduced concentration is required in elderly people. The usual maintenance daily dose is 25-35 mmol (lithium carbonate 925-1300 mg) for patients aged <40 years; 20-25 mmol (740-925 mg) for those aged 40-60 years; and 15-20 mmol (550-740 mg) for patients aged >60 years. The initial recommended dose is usually 12-24 mmol (450-900 mg) per day, depending on age and bodyweight. The classical administration schedule is two or three times daily, although there is no strong evidence in favour of a three-times-daily schedule, and compliance with the midday dose is questionable. With a modern sustained-release preparation, the twice-daily schedule is well established, although one single evening dose is being recommended by a number of expert panels.

Abstract
One of the least-developed areas of clinical pharmacology and drug research is the use of medication during pregnancy and lactation. This article is the first in a two-part series designed to familiarize physicians with many aspects of the drugs they commonly prescribe for pregnant and breast-feeding women. Almost every pregnant woman is exposed to some type of medication during pregnancy. Although the majority of pregnant and breast-feeding women consume clinically indicated or over-the-counter drug preparation regularly, only few medications have specifically been tested for safety and efficacy during pregnancy. There is scant information on the effect of common pregnancy complications on drug clearance and efficacy. Often, the safety of a drug for mothers, their fetuses, and nursing infants cannot be determined until it has been widely used. Absent this crucial information, many women are either refused medically important agents or experience potentially harmful delays in receiving drug treatment. Conversely, many drugs deemed "safe" are prescribed despite evidence of possible teratogenicity. Novel research and diagnostic applications evolving from the opportunities presented by the advances in genomics and proteomics are now beginning to affect clinical diagnosis, vaccine development, drug discovery, and unique therapies in a modern diagnostic-therapeutic framework-part of the new scientific field of theranostics. This review critically explores a number of recently raised issues in regard to the use of several classes of medications during gestation and seeks to provide a general and concise resource on drugs commonly used during pregnancy and lactation. It also seeks to make clinicians more aware of the controversies surrounding some drugs in an effort to encourage safer prescribing practices through consultation with a maternal-fetal medicine specialist and through references and Web sites that list up-to-date information.

Abstract
The aim of this article is to review the main methods of treatment of anxious and depressive disorders during pregnancy and the postpartum. To this end, we analyse recent publications about the use and efficacy of psychotherapy and psychosocial interventions (cognitive behavioural therapy, interpersonal psychotherapy, psychoanalytical therapy) in the perinatal period. We also review recent papers about the use of psychotropic medication during pregnancy and breast-feeding, with special emphasis on clinical trials. We particularly focus on the risk/benefit assessment of antidepressants, mood stabilisers, antipsychotics and benzodiazepines, in terms of teratogenicity, and impact on neonatal adaptation and neuropsychological development. Various treatment modalities are presented and discussed. It appears that psychotherapies have proved their efficiency on most pre- and postpartum anxious and depressive disorders and represent a first line treatment in most cases. Psychopharmacological treatment is indicated for severe anxious and depressive disorders. The risks of such medication, especially antidepressants, may have been overestimated in the past. Provided reasonable precautions are taken and mothers and future mothers receive clear information on the potential risks and benefits, psychotropic medication could be more broadly prescribed during pregnancy and the breast-feeding period.

Postpartum affective disorders continue to be a major health issue for women. There is a general belief that electroconvulsive therapy (ECT) is effective in treating severe or treatment-refractory postpartum affective illnesses, but evidence to support this assertion is lacking. In this case series, we present 5 cases of women with postpartum depression and psychosis, all of whom had failed prior pharmacological therapy. All 5 women had a significant response within 3 to 6 treatments with ECT. Our findings suggest that ECT is overall an effective treatment of postpartum illnesses. In addition to being an excellent choice for women who have failed prior medication trials, ECT may also be considered for women whose severity of illness necessitates rapid symptom resolution.

Abstract
Despite the traditional notion that pregnancy is a time of joy and emotional well being, evidence suggests that it does not protect women against mental illness. Untreated mental illness carries wide-ranging repercussions for mother, child and family that often outweigh those associated with treatment. Clinical management is complex, involving competing risks to mother and offspring; the challenge lies in effectively treating mental illness, whilst minimising exposure of the child to harmful medication. The paucity of robust published evidence on which to base the principles of psychiatric care further compounds the issue. Pregnancy significantly affects plasma drug levels and immature foetal/neonatal physiology renders the child prone to damage from pharmacological agents, all of which cross the placenta/enter breast-milk to varying degrees. Risks include teratogenicity, obstetrical complications, perinatal syndromes, and long-term behavioural problems. Despite evidence that some psychotropic drugs may be safe during pregnancy, knowledge regarding the risks of antenatal exposure to medications remains far from complete. The pregnant or breastfeeding woman requires an individualised risk-benefit analysis with regard to the commencement or continuance of psychotropic medication. If treatment is deemed necessary, monotherapy at the lowest possible dose should be prescribed. More robust safety data is available for older psychotropic drugs, which should be employed in preference to newer agents with unestablished safety profiles. Pregnant/breastfeeding women should also be educated with regard to early detection of signs of drug toxicity in both themselves and their babies. Despite shared responsibility, the ultimate decision with regard to reasonable risk, and what constitutes it, rests with the informed patient. Close psychiatric monitoring and coordinated multidisciplinary care with the obstetrician and paediatrician combine with such informed patient choices to comprise the components of a holistic model of care, targeted at optimizing the complex management of women with psychiatric illness during pregnancy.

Abstract
Bipolar disorder is a major cause of disability, and the prevention of relapse is a key management goal. Pharmacological interventions, effectively delivered through enhanced clinical care, are central to long-term management. This article summarises the available evidence for a range of pharmacological options, and provides guidance on common issues in clinical management in line with current practice guidelines. The use of medications for long-term prophylaxis should be considered in all patients meeting criteria for bipolar I disorder. Increasing high-quality evidence from randomised trials informs management decisions relating to both novel agents, such as lamotrigine and olanzapine, and longer-established therapies, such as lithium and valproate, in monotherapy. Medications taken long-term in bipolar disorder differ in the extent to which they protect against manic and depressive relapse. Consequently, the emerging challenge is to understand how combination treatments can enhance efficacy and effectiveness based on data from controlled trials rather than random polypharmacy. Clinical care can be enhanced with effective education about the illness, and the use of strategies to improve treatment adherence and the recognition and management of stressors or prodromal symptoms. Where available, a range of specific psychological interventions can be effective as an adjunct to medication. When discontinuation of prophylaxis is necessary, gradual tapering of dose over weeks or months is recommended.

Abstract
Many new mothers who need antidepressant or mood-stabilising drug treatment may wish to breastfeed their infants, but are hesitant to do so because of possible harmful effects of the medication on the infant. This article reviews current data on drug excretion into breast milk and the effects on the breast-fed child, and provides recommendations for the use of the different psychotropic drugs in lactating women. Relevant literature was identified through systematic searches of MEDLINE, EMBASE and the Science Citation Index Expanded (ISI) from 1966 to February 2005. The present knowledge is based on the accumulation of case studies. No randomised controlled trials in breast-fed infants have been performed and there is a lack of long-term follow-up studies. Use of SSRIs and TCAs (except doxepin) is compatible with breastfeeding. However, if treatment with an SSRI is started in the postpartum period, fluoxetine and citalopram may not be drugs of first choice. With regard to other antidepressants, such as venlafaxine, trazodone, mirtazapine, reboxetine, moclobemide and other MAOIs, very little knowledge exists. Breastfeeding should be avoided while using lithium. Carbamazepine and sodium valproate (valproic acid) are generally better tolerated by the breast-fed infant than lithium. Data on lamotrigine are still sparse. Knowledge is also scarce on the novel antipsychotics and thus recommendations in lactating women cannot be made for these agents. It is unwise to expose infants unnecessarily to drugs that may have severe adverse effects. As such, clozapine should probably be avoided because of the risk of agranulocytosis. Our knowledge of the impact of drug exposure through breast milk is still limited. Infant drug exposure is, however, generally higher during pregnancy through placental passage than through breast milk. Despite the low dosage transferred to the infant through breast milk, premature infants and infants with neonatal diseases or inherited disturbances in metabolism may be vulnerable to such exposure.

Abstract
BACKGROUND Postnatal depression is a common and important complication of childbearing. Untreated depression can lead to potentially negative effects on the foetus and infant, in addition to serious morbidity for the mother. The use of antidepressants during pregnancy for prevention of postnatal depression is unclear, due to the possibility of adverse effects on the mother and developing foetus, and the difficulty of reliably identifying the women who would go on to develop postnatal depression. OBJECTIVES To evaluate the effectiveness of different antidepressant drugs in addition to standard clinical care in the prevention of postnatal depression. To compare the effectiveness of different antidepressant drugs and with any other form of intervention for postnatal depression i.e. hormonal, psychological or social support. To assess any adverse effects of antidepressant drugs in either the mother or the foetus/infant. SEARCH STRATEGY The register of clinical trials maintained and updated by the Cochrane Depression, Anxiety and Neurosis Group and the Cochrane Pregnancy and Childbirth Group. SELECTION CRITERIA Randomised studies of antidepressants alone or in combination with another treatment, compared with placebo or a psychosocial intervention in non-depressed pregnant women or women who had given birth in the previous six weeks (i.e. women at risk of postnatal depression) DATA COLLECTION AND ANALYSIS Data were extracted independently from the trial reports by the authors. Missing information was requested from investigators wherever possible. Data were sought to allow an "intention to treat" analysis. MAIN RESULTS Two trials fulfilled the inclusion criteria for this review. Both looked at women with a past history of postpartum depression. Nortriptyline (n=26) (Wisner 2001) did not show any benefit over placebo (n=25). Sertraline (n=14) Wisner 2004 reduced the recurrence of postnatal depression and the time to recurrence when compared with placebo (n=8). Intention to treat analyses were not carried out in either trial. AUTHORS' CONCLUSIONS It is not possible to draw any clear conclusions about the effectiveness of antidepressants given immediately postpartum in preventing postnatal depression and, therefore, cannot be recommended for prophylaxis of postnatal depression, due to the lack of clear evidence. Larger trials are needed which also include comparisons of antidepressant drugs with other prophylactic treatments to reflect clinical practice, and examine adverse effects for the foetus and infant, as well as assess womens' attitudes to the use of antidepressants at this time.

Abstract
We present the case of a breast-feeding woman with acute psychotic symptoms after delivery, which were treated with the antipsychotic agent risperidone. Serum levels of risperidone and 9-hydroxyrisperidone could be detected in both the mother and her infant. Drug-levels in breast milk were ten-fold lower compared to maternal serum. The patient responded well to antipsychotic treatment. Her infant did not display any adverse effects and psychomotor development was normal. In this case, risperidone was a safe treatment option for the breast-feeding mother and her infant. We also provide a brief overview of the clinically relevant data concerning antipsychotics and breast-feeding.

Abstract
This article reviews the risk factors, pathogenesis, treatment, and prevention of postpartum depression. Postpartum depression is common and occurs in up to 18% of newly delivered mothers. Though the hormonal changes occurring after childbirth are believed to play a role in postpartum depression, no hormonal etiology has been identified. Estrogen appears somewhat helpful for postpartum depression, but its use is limited by problematic medical sequelae. Several antidepressants are effective for postpartum depression and appear safe for use by breastfeeding women. Psychosocial interventions and cultural rituals, which may prevent or ameliorate postpartum depression, have also been employed.

Abstract
The most recent Confidential Enquiry into the causes of maternal deaths during the perinatal period in England and Wales (1994-1996) revealed that psychological illness was at least as important as hypertensive disorders. It is therefore important for obstetricians to be aware of a variety of psychiatric conditions as well as the psychotropic medication prescribed and sequelae of continuation or withdrawal of these drugs. Best management, of this particularly vulnerable group of women, requires close liaison with the psychiatric team. This chapter considers four groups of women most likely to be prescribed psychoactive drugs during the perinatal period: (i) women with mental illness wishing to conceive, (ii) women with mental illness who conceive while taking medication, (iii) those who become mentally ill while pregnant, and (iv) those who become unwell postnatally. Guidelines for treatment are discussed.

Abstract
BACKGROUND The pharmacological treatment of depression in nursing women requires information on the magnitude of medication exposure to the infant that may occur through breast milk. AIMS To examine serum concentrations of antidepressants in infants exposed to these medications through breast-feeding. METHOD Maternal and infant serum concentrations of sertraline, paroxetine and fluvoxamine were determined with high-performance liquid chromatography (limit of detection=1 ng/ml). RESULTS No detectable medication was present in any infant exposed to paroxetine (n=16) or fluvoxamine (n=4). Among infants exposed to sertraline (n=30), detectable medication was present in 24% of serum samples. A significant negative correlation was found between infant age and infant serum concentration. Sertraline was significantly more likely to be detected in an infant if the mother's daily dose was 100 mg or higher. No adverse sequelae occurred in any infant. CONCLUSIONS This study shows that paroxetine, fluvoxamine and sertraline produce minimal exposure to infants when taken by nursing mothers.

Abstract
BACKGROUND Postnatal depression is a common disorder, which can have profound short and long term effects on maternal morbidity, the new infant and the family as a whole. Social factors appear to be particularly important in the aetiology and prognosis of postnatal depression and treatment is often largely social support and psychological interventions. It is not known whether antidepressants are an effective and safe choice for treatment of this disorder. OBJECTIVES To evaluate the effectiveness of different antidepressant drugs and compare their effectiveness with other forms of treatment. To assess any adverse effects of antidepressants in the mother or the nursing baby. SEARCH STRATEGY The registers of clinical trials maintained and updated by the Cochrane Depression, Anxiety and Neurosis Group and the Cochrane Pregnancy and Childbirth Group were searched. Other databases (outlined below) were also searched and contacts were made with pharmaceutical companies and experts in the field. SELECTION CRITERIA All trials were considered in which women with depression in the first six months postpartum were randomised to receive antidepressants alone or in combination with another treatment, or to receive any other treatment including placebo. DATA COLLECTION AND ANALYSIS Data was extracted independently from the trial reports by the reviewers. Missing information was requested from investigators wherever possible. Data was sought to allow an "intention to treat" analysis. MAIN RESULTS Only one trial could be included in this review, leaving most of the objectives of the review unfulfilled. Appleby et al (1997) reported that Fluoxetine was significantly more effective than placebo and, after an initial session of counselling, as effective as a full course of cognitive-behavioural counselling in the treatment of postnatal depression. There was no interaction between medication and counselling. REVIEWER'S CONCLUSIONS Women with postnatal depression can be effectively treated with fluoxetine, which is as effective as a course of cognitive-behavioural counselling in the short-term. However, more trials with a longer follow-up period are needed to compare different antidepressants in the treatment of postnatal depression, and to compare antidepressant treatment with psychosocial interventions. This is an area that has been neglected despite the large public health impact described above.
