Background and objectives
Although indomethacin has been widely used for the treatment of preterm labor
over the past 40 years, there are few reports regarding its pharmacokinetics in pregnant
women.
Methods
This opportunistic study assessed the steady-state pharmacokinetics of
indomethacin in pregnant subjects to whom an oral dose of 25 mg every 6 h was
prescribed. Indomethacin concentrations in plasma and urine were analyzed by a validated
high-performance liquid chromatography method with mass spectrometric detection.
Results
The mean area under the plasma concentration versus time curve at steady state
(AUCss) was 1.91 ± 0.53 lg h/mL, mean peak plasma concentration
(Cmax) was 1.02 ± 0.49 lg/mL, and mean time to
reach Cmax (tmax) was 1.3
± 0.7 h. The mean apparent clearance at steady state was 14.5 ± 5.5 L/h,
which is higher than the apparent clearance reported in the literature for non-pregnant
subjects. Indomethacin crosses the placenta; the mean fetal/maternal ratio from five
sets of cord blood samples collected at delivery was 4.0 ± 1.1.
Conclusions
Further studies are needed to determine whether any dose adjustments are
necessary as a result of the increased clearance of indomethacin during pregnancy.
This study investigated the utilization of health information technology (HIT) to enhance resource utilization in a geographically dispersed tertiary care system with extensive outpatient and delivery services. It was initiated as a result of a systems change implemented after Hurricane Ike devastated southeast Texas. A retrospective database and electronic medical record review was performed, which included data collection from all patients evaluated 18 months prior (epoch I) and 18 months following (epoch II) the landfall of Hurricane Ike. The months immediately following the storm were omitted from the analysis, allowing time to establish a new baseline. We analyzed a total of 21,201 patients evaluated in triage at the University of Texas Medical Branch. Epoch I consisted of 11,280 patients and epoch II consisted of 9922 patients. Using HIT, we were able to decrease the number of visits to triage while simultaneously managing more complex patients in the outpatient setting with no clinically significant change in maternal or fetal outcome. This study developed an innovated model of care using constrained resources while providing quality and safety to our patients without additional cost to the health care delivery system.
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.
