Women who suffer with psychotic conditions who become pregnant are usually treated with antipsychotic drugs. The risks of harm to the offspring associated with exposure to these drugs, in utero or through breast-feeding, are unknown. We aimed to find good quality evidence from randomised controlled trials on the risks and benefits of antipsychotic drugs during pregnancy and breastfeeding for both the woman and the foetus/infant. We found none. Ethical constraints concerning randomisation of treatment for pregnant and breastfeeding women, the logistics of such a study and a lack of impetus from the pharmaceutical industry in this area may explain the lack of research. However, the continued use of antipsychotic drugs in these women during pregnancy and lactation without sound evidence raises serious clinical and ethical concerns.
阅读完整摘要
Antipsychotics are commonly prescribed for women suffering psychotic illnesses during pregnancy and the postpartum period. The potential adverse consequences of these different options are multiple and complex, impacting on the foetus, neonate, infant and early development of the child as well as the woman herself.
研究目的
To establish whether the benefits of taking antipsychotic drugs outweigh the risks for pregnant or post partum women.
检索策略
The Cochrane Schizophrenia Group's Register (January 2003) was searched in order to identify all published trials of women during pregnancy or the postpartum period. We inspected all references of all identified studies. If any studies had been found, the first authors of each included study would have been contacted.
纳入排除标准
Randomised controlled clinical trials investigating the effects of any type of antipsychotic drug compared with any other treatment option (including standard psychosocial care, any other antipsychotic drug, or an alternative therapy such as electro-convulsive therapy or cognitive behavioural therapy) and involving pregnant women and/or women during the postpartum period diagnosed with a non-affective psychotic disorder.
资料收集与分析
Citations, and where possible, abstracts were independently inspected by reviewers and the papers ordered were scrutinised and quality assessed. Data would have been extracted independently by at least two reviewers. Binary outcomes were to have been analysed using Relative Risks (RR) and their 95% Confidence Intervals (CI).
主要结果
We found no trials that met the broad inclusion criteria.
作者结论
Current guidelines and clinical practice for the use of antipsychotic drugs in women with non-affective disorders during pregnancy and postpartum are not based on evidence from randomised controlled trials. Although ethical concerns have to date precluded the use of randomised controlled trials to address this research topic, the continued use of antipsychotic drugs in this group of women in itself poses significant clinical and ethical problems. Evidence is required from large pragmatic trials that reflect routine clinical practice, examine a broad range of outcomes and accurately quantify risks and benefits to both mothers and their offspring, so that comparison between different treatment options can be made.
