Changes in maternal physiology during pregnancy can alter the absorption, distribution, and clearance of many drugs. When presented with a clinical situation in which it does not appear that a prescribed drug is working, clinicians must either change drugs or increase the dose of the current drug to achieve the desired clinical effect. A case highlighting antihypertensive medication in pregnancy and the effect of changed drug-metabolizing enzymes is presented. Understanding pregnancy's effect on drug-metabolizing enzymes, transporters, and receptors can help clinicians make individualized pharmacotherapeutic decisions for patients. Pharmacogenetics potentially can aid clinicians in treating pregnant women in the future as more data are generated and individualized therapeutic models are constructed.
怀孕期间母体生理学的变化可改变许多药物的吸收、分布和清除。当临床情况表明某种规定药物无效时,临床医生必须更换药物或增加当前药物的剂量以达到预期的临床效果。本文介绍了妊娠期间抗高血压药物的应用以及改变的药物代谢酶的作用。了解妊娠对药物代谢酶、转运体和受体的影响有助于临床医生为患者做出个体化的药物治疗决策。随着更多数据的产生和个体化治疗模型的构建,药物遗传学有望在未来帮助临床医生治疗孕妇。
