Antidepressant Therapy for Improved Blood Vessel Health After Preeclampsia
A Early Phase 1 study testing Paroxetine Hydrochloride and Ascorbic acid (Vitamin C) in people with Preeclampsia and Endothelial Function, run by Anna Stanhewicz, PhD at 1 site in United States.
Trial summary
Preeclampsia is a condition in pregnancy where a woman develops high blood pressure and other complications. Women who develop preeclampsia are 4 times more likely to have heart disease later in life. They are also more likely to have depression after pregnancy. Read more about this study

About this study
Official title: Role of Antidepressant Therapy to Improve Vascular Function After Preeclampsia
Preeclampsia is a condition in pregnancy where a woman develops high blood pressure and other complications. Women who develop preeclampsia are 4 times more likely to have heart disease later in life. They are also more likely to have depression after pregnancy. Why they are more likely to develop these conditions is not known. It may be because their blood vessels were damaged during pregnancy. Changes in blood vessel health can predict heart disease. These changes have been recorded after pregnancy in women who had preeclampsia. These changes have also been recorded in women who have depression. In the previous phase of this award, we found that women who had preeclampsia in pregnancy had changes in blood vessel health after pregnancy. We also found that if these women were taking a medicine to treat depression, their blood vessel health was normal. This could mean that treatment for depression can also increase blood vessel health in women who had preeclampsia. In this project we will study how changes in blood vessel health are related to preeclampsia and depression in women who have had both. We will also study how medicine to treat depression can improve blood vessel health after preeclampsia. We will do this by measuring how blood vessels work in women who have had preeclampsia compared to women who did not, and in women who have depression and women who do not. This will tell us more about why risk for depression and heart disease is higher in women who have had preeclampsia. It will also help us understand if medicine for depression can reduce cardiovascular disease risk after preeclampsia.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Paroxetine HydrochlorideDrug
Localized delivery of paroxetine HCl to the cutaneous microvasculature via intradermal microdialysis.
Ascorbic acid (Vitamin C)Drug
Localized delivery of ascorbic acid to the cutaneous microvasculature via intradermal microdialysis.
| Study group | Role | What they receive |
|---|---|---|
| Cutaneous Vascular Response to Local Heat | Experimental | All women will complete the same protocol, regardless of pregnancy history and depression status.
Four intradermal microdialysis fibers will be placed in the ventral forearm for the local delivery of: (1) lactated Ringer's (control), (2) paroxetine HCl, (3) ascorbic acid, or (4) paroxetine HCl + ascorbic acid. Skin blood flow will be measured with laser-Doppler flowmetry directly over each microdialysis fiber during a standard local heating protocol to 42 degrees Celsius. Once a stable plateau in blood flow has been reached, each site is perfused with L-NAME to inhibit nitric oxide synthase. Following a post-L-NAME plateau, maximal dilation is induced by perfusing sodium nitroprusside and increasing local temperature to 43 degrees Celsius. Receives: Drug: Paroxetine Hydrochloride; Drug: Ascorbic acid (Vitamin C) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Microvascular endothelium-dependent dilation response measured by laser-Doppler flowmetry
Cutaneous vascular conductance responses to local heating over a microdialysis fiber receiving treatments compared to lactated Ringer's solution (control).
Measured: at the study visit, an average of 4 hours
Nitric oxide-dependent dilation response measured by laser-Doppler flowmetry
Difference in cutaneous vascular conductance between local heating plateau and post-L-NAME plateau within each treated microdialysis site compared to lactated Ringer's (control).
Measured: at the study visit, an average of 4 hours

Women who develop preeclampsia are 4 times more likely to have heart disease later in life. They are also more likely to have depression after pregnancy.

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing Paroxetine Hydrochloride and Ascorbic acid (Vitamin C) in people with Preeclampsia and Endothelial Function, run by Anna Stanhewicz, PhD at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 28 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Anna Reid-Stanhewicz, PHD (319-467-1732, anna-stanhewicz@uiowa.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Microvascular endothelium-dependent dilation response measured by laser-Doppler flowmetry (time frame: at the study visit, an average of 4 hours). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Oct 2026.
