For women infected with the human immunodeficiency virus (HIV) who become pregnant, the use of combination antiretroviral therapy (ART) significantly reduces transmission of HIV from mother to child. Selection of an appropriate ART regimen for use among pregnant women requires consideration of numerous factors including maternal and fetal safety, antiretroviral pharmacokinetics, and regimen efficacy. Optimization of antiretroviral pharmacokinetics during pregnancy requires special consideration because pregnancy-associated changes in drug absorption, distribution, metabolism, and excretion are known to occur throughout pregnancy and postpartum. Understanding antiretroviral placental transfer may offer additional insight into each drug's potential role in preventing HIV transmission in utero and may also have implications regarding viral resistance in cases where transmission does occur. In this review, we summarize key published data describing antiretroviral pharmacokinetics in pregnant women, providing suggestions for clinical application of these data where appropriate.
Integration of specialty pharmacy services with the interdisciplinary care provided in the outpatient NM ID clinic has enhanced continuity of care for patients with HIV infection in terms of prescription filling, medication counseling, and adherence monitoring.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
