Each subject will receive 2-4 of the listed interventions.
NCT01348880 ↗ Vardenafil ODT (Orally Disintegrating Tablet) - Nifedipine Interaction Study Completed GlaxoSmithKline Phase 1 2011-05-01 The study will be conducted as a multi-center, randomized, double-blinded, placebo controlled, crossover design. The investigational drug (vardenafil ODT (Orally Disintegrating Tablet)/placebo) will be given as a single administration at a dose of 10 mg vardenafil ODT during Period 1 or 2; the blinded matching placebo will be given as a single administration during the opposing period. The random code will determine the order of active drug (vardenafil ODT) and placebo for each subject. Blood pressure and heart rate profiles will be recorded by automated device pre-dose for 8 hours post-dose during Periods 1 and 2. The non investigational drug product (vasodilator), Procardia XL, will be background treatment for hypertension, taken daily by each subject. All subjects must be stable on the vasodilator for at least 4 weeks prior to Day 1 of Period 1. Special conditions for this study include the requirement that all subjects will be male, are between the ages of 65 and 80 years, and will have a diagnosis of erectile dysfunction (ED), as well as hypertension. Planned sample size will be 40 subjects evaluable for the primary analysis. Of the 40 subjects valid for this analysis, 20 will be between the ages of 65 and 69 years, and 20 subjects will be between the ages of 70 and 80 years. The total duration of the study will be approximately one year from first subject treated to last subject treated, including replacement of any subjects who fail to complete both periods of crossover dosing.

The total duration of the study will be approximately one year from first subject treated to last subject treated, including replacement of any subjects who fail to complete both periods of crossover dosing.
NCT02438371 ↗ Nifedipine or Nifedipine Plus Indomethacin for Treatment of Acute Preterm Labor Terminated The University of Texas Health Science Center, Houston Phase 4 2015-05-01 Tocolytic agents are used for the treatment of preterm labor. It is unclear whether combination treatments of two tocolytic agents are more effective in stopping preterm labor compared to one. Therefore, the investigators propose a comparative effective trial of nifedipine plus indomethacin vs. nifedipine alone for the treatment of preterm labor
NCT02933593 ↗ Changes in Central Arterial Pressure When Comparing ACOG Hypertensive Urgency Protocols Withdrawn St. Louis University N/A 2016-08-01 The investigators plan to monitor the central blood pressure in women with severely elevated blood pressures (160/110) in pregnancy in the acute setting. Currently ACOG recommends 3 different options for blood pressure control, however no one has studied how these medications affect the central pressures, only peripheral blood pressure.
