Abstract
Abstract
Objectives
The second-generation antipsychotic quetiapine has been demonstrated to undergo gestation-related changes in pharmacokinetics. This study applied pharmacokinetic modelling principles to investigate the mechanism of these changes and to propose new dosing strategies to counteract these changes.
Methods
A pharmacokinetic modelling approach was implemented using virtual population groups. Changes in quetiapine trough plasma concentration during gestation were quantified across all trimesters, and dose adjustment strategies were applied to counteract these changes by targeting a therapeutic range of 50–500 ng/ml throughout gestation.
Key findings
The application of the model during gestation predicted a decrease in trough concentration. A maximum decrease of 58% was predicted during trimester 2, and being associated with a statistically significant decrease in oral clearance at gestation week 25, 204 l/h ± 100.8 l/h compared with non-pregnant subjects, 121.9 l/h ± 51.8 l/h. A dosing optimisation strategy identified that dose increases to 500–700 mg twice daily would result in 32–55% of subjects possessing trough concentration in excess of 50 ng/ml.
Conclusions
Quetiapine doses in pregnancy should be increased to 500–700 mg twice daily to counteract a concomitant increase in metabolic clearance, increase in volume of distribution and decrease in plasma protein binding.

Abstract
Lithium and antipsychotics are often prescribed to treat bipolar disorder or psychotic disorders in women of childbearing age. Little is known about the consequences of these medications during pregnancy for the developing child. The objective of this article is to systematically review findings from preclinical and clinical studies that have examined the neurodevelopmental consequences of intrauterine exposure to lithium and antipsychotics. A systematic search was performed in Embase, Medline, Web of Science, PsychINFO, Cochrane, and Google Scholar. Clinical and experimental studies were selected if they investigated neurodevelopment of offspring exposed to lithium or antipsychotics during gestation. Quality of clinical and preclinical studies was assessed by the Newcastle-Ottawa Scale and the SYRCLE's risk of Bias tool, respectively. In total, 73 studies were selected for qualitative synthesis and three studies were selected for quantitative synthesis. Of preclinical studies, 93% found one or more adverse effects of prenatal exposure to antipsychotics or lithium on neurodevelopment or behaviour. Only three clinical cohort studies have investigated the consequences of lithium exposure, all of which reported normal development. In 66% of clinical studies regarding antipsychotic exposure, a transient delay in neurodevelopment was observed. The relative risk for neuromotor deficits after in utero exposure to antipsychotics was estimated to be 1.63 (95% CI 1.22-2.19; I2 = 0%). Preclinical studies suggest long-term adverse neurodevelopmental consequences of intrauterine exposure to either lithium or antipsychotics. However, there is a lack of high-quality clinical studies. Interpretation is difficult, since most studies have compared exposed children with their peers from the unaffected population, which did not allow correction for potential influences regarding genetic predisposition or parental psychiatric illness.

Abstract
Management of bipolar during pregnancy and postpartum is very challenging. The treating clinicians have to take into account various factors like current mental state, longitudinal history of the patient, past history of relapse while off medication, response to medication, time of pregnancy at which patient presents to the clinician, etc. The choice of drug should depend on the balance between safety and efficacy profile. Whenever patient is on psychotropic medication, close and intensive monitoring should be done. Among the various mood stabilizers, use of lithium during the second and third trimester appears to be safe. Use of valproate during first trimester is associated with major malformation and long-term sequalae in the form of developmental delay, lower intelligence quotient, and higher risk of development of autism spectrum disorder. Similarly use of carbamazepine in first trimester is associated with higher risk of major congenital malformation and its use in first trimester is contraindicated. Data for lamotrigine (LTG) appears to be more favorable than other antiepileptics. During lactation, use of valproate and LTG is reported to be safe. Use of typical and/atypical antipsychotic is a good option during pregnancy in women with bipolar disorder.

Abstract
Many women with psychiatric disorders want to become mothers and only a minority seek advise prior to becoming pregnant. In those women, in whom pregnancy can be planned, the decision, if a medication is required for stabilisation and which one to choose if this is the case, is easier to make than in women in whom pregnancy occurs unplanned. The physician has to weigh the risk that a relapse of the psychiatric disorder during pregnancy poses to the foetus against the reproductive risk of psychotropic drugs. This presentation is intended to assist in understanding the general principles of pharmacotherapy during pregnancy as well as the morphological, perinatal and neurobehavioural toxicity of antidepressants, antipsychotics, benzodiazepines and mood stabilisers.

Abstract
OBJECTIVES Second-generation antipsychotics (SGAs), in conjunction with other psychotropic medications, are increasingly used to treat psychiatric disorders in pregnancy. The few available studies investigating the reproductive safety of SGAs did not reach conclusive results, and none have compared monotherapy with polytherapy involving other psychotropic medications. DESIGN Descriptive cohort study using a prospectively collected database. SETTING Motherisk Program, The Hospital for Sick Children, Toronto, Canada. PARTICIPANTS 133 women exposed to SGAs and other psychotropic drugs and 133 matched healthy controls were assessed and analysed. Outcomes of mother-child pairs exposed to SGAs in monotherapy (N=37) were compared with those exposed to SGAs with other psychotropic medications (in polytherapy; N=96). MAIN OUTCOME MEASURES Maternal, pregnancy, delivery and neonatal outcomes. RESULTS 72% of exposed women received SGAs in polytherapy, and 101 women took their medications throughout pregnancy. These women had significantly higher pre-pregnancy weight, experienced more associated comorbidities and instrumental deliveries, and delivered a greater proportion of large for gestational age neonates. There were no differences in maternal weight gain in pregnancy between the exposed and comparison groups and between the monotherapy-exposed and polytherapy-exposed subgroups. The exposed neonates were more likely to be born premature, were admitted more often to the neonatal intensive care unit, presented with poor neonatal adaptation signs and had higher rates of congenital malformations. All the aforementioned neonatal outcomes were found mainly in the polytherapy subgroup. CONCLUSIONS The use of SGAs in polytherapy was prevalent in the assessed cohort and was associated with adverse pregnancy outcomes for both the mother and the child. In utero exposure to SGA monotherapy appears to be associated with less risk to the fetus. Future research should focus on polytherapy in pregnancy in order to define its reproductive safety and to separate the effects of medication exposure, underlying psychopathology and associated comorbidities.

Abstract
The objective of this article is to review clinical differences between men and women with bipolar disorder. The secondary objective is to analyze the differences in adherence to medication between genders. Men usually present with manic episodes and have comorbid drug abuse, while women usually present with major depressive episode, the onset is often later, comorbidity of physical pathology is common and adherence to medication is greater than in men. In women who have an earlier onset of the illness and are single, the risk of nonadherence is higher than in other groups of women. There are two time periods that are very important in women: pregnancy and postpartum. Both are critical periods and a relapse or recurrence of symptoms at either stage can have serious consequences for the woman and/or her baby. In addition, the effect of medication on the fetus is unclear. In conclusion, there is a clear need for more studies on gender differences in bipolar disorder and how to improve adherence to treatment. Moreover, a better understanding of how to treat women with bipolar disorder during pregnancy and lactation will undoubtedly lead to improved outcomes for both the mother and her child.

Abstract
OBJECTIVE Both first- (FGAs) and second-generation antipsychotics (SGAs) are routinely used in treating severe and persistent psychiatric disorders. However, until now no articles have analyzed systematically the safety of both classes of psychotropics during pregnancy. DATA SOURCES AND SEARCH STRATEGY: Medical literature information published in any language since 1950 was identified using MEDLINE/PubMed, TOXNET, EMBASE, and The Cochrane Library. Additional references were identified from the reference lists of published articles. Bibliographical information, including contributory unpublished data, was also requested from companies developing drugs. Search terms were pregnancy, psychotropic drugs, (a)typical-first-second-generation antipsychotics, and neuroleptics. A separate search was also conducted to complete the safety profile of each reviewed medication. Searches were last updated on July 2008. DATA SELECTION All articles reporting primary data on the outcome of pregnancies exposed to antipsychotics were acquired, without methodological limitations. CONCLUSIONS Reviewed information was too limited to draw definite conclusions on structural teratogenicity of FGAs and SGAs. Both classes of drugs seem to be associated with an increased risk of neonatal complications. However, most SGAs appear to increase risk of gestational metabolic complications and babies large for gestational age and with mean birth weight significantly heavier as compared with those exposed to FGAs. These risks have been reported rarely with FGAs. Hence, the choice of the less harmful option in pregnancy should be limited to FGAs in drug-naive patients. When pregnancy occurs during antipsychotic treatment, the choice to continue the previous therapy should be preferred.
