Women may have a contraindication to a specific medication (e.g., severe asthma and beta-blockers) or a characteristic that makes an agent preferable (e.g., Black race and calcium channel blockers). There is no renoprotection agent that can replace ACE inhibitors or ARBs for women with diabetes mellitus and pre-pregnancy microalbuminuria; however, BP control is both a critical element of ACE inhibitor renoprotection and can be provided by other antihypertensives. Some ACE inhibitors are acceptable during breastfeeding

(see ‘Severe Hypertension’). Labetalol and methyldopa are the oral agents used most frequently in Canada [350] (Table 7). ACE inhibitors and ARBs are fetotoxic [351] (particularly nephrotoxic) [352]. Prazosin may cause stillbirths [353]. Atenolol (in contrast with other cardioselective NVP-BKM120 mw beta-blockers) may associated with reduced fetal growth velocity [354], [355],

[356], [357] and [358], making other agents preferable. Oral hydralazine monotherapy is not recommended due to maternal side effects [359]. Thiazide diuretics can be used [238]. Oral antihypertensives do not appear to change FHR or pattern; relevant changes are best attributed to evolution of the underlying HDP, not to the antihypertensive agent. The cost-effectiveness of antihypertensives for severe or non-severe hypertension Galunisertib in vitro is unknown. 1. Antenatal corticosteroid therapy should be considered for all women who present with preeclampsia at ⩽346 weeks gestation (I-A; High/Strong). When administered at ⩽ 346 weeks, antenatal corticosteroids accelerate fetal pulmonary maturity and decrease neonatal mortality and morbidity, including women with HDPs [360]. RCTs that administered steroids Carnitine dehydrogenase at 330 to 346 weeks resulted in reduced neonatal RDS [360], a subject of ongoing trials. The beneficial effects of steroids can be observed when the first dose is administered as late as within 4 h before birth. There is no evidence of short- or long-term maternal or fetal adverse effects of

a single course of antenatal corticosteroids. If expectantly managed, women with preeclampsia remote from term (usually <340 weeks) will be delivered within two weeks of corticosteroid administration, but the duration of pregnancy prolongation varies from hours to weeks. All eligible women with preeclampsia should receive antenatal corticosteroids. If women with preeclampsia remain pregnant seven or more days after receipt of antenatal corticosteroids, there is insufficient information available to recommend another course. Repeated dose antenatal corticosteroids are associated with short-term neonatal respiratory, without demonstrated long-term, benefits [361] and some concern about harm [362]. One third of women with gestational hypertension at <340 weeks will develop preeclampsia over an average of 5 weeks; delivery is unlikely within 7 days [65].
