Ondansetron and Blood Coagulation
A study testing 0 ul of ondansetron, 0.2 ul of ondansetron and 2 ul of ondansetron in people with Blood Coagulation Disorder, run by Seoul National University Bundang Hospital at 1 site in South Korea.
Trial summary
Ondansetron may alter whole blood coagulation. However, little is known about the dose-response relationships according to the blood concentration of ondansetron. The investigators therefore will perform the present study to measure the effect of ondansestron on the blood coagulation pathway according to the drug… Read more about this study

About this study
Official title: The Effect of an Ondansetron on Blood Coagulation: In Vitro, Volunteer Study Using Rotational Thromboelastometry
Ondansetron may alter whole blood coagulation. However, little is known about the dose-response relationships according to the blood concentration of ondansetron. The investigators therefore will perform the present study to measure the effect of ondansestron on the blood coagulation pathway according to the drug concentration level using a thromboelastography test.
- Conditions
- Blood Coagulation Disorder
- Being tested
- 0 ul of ondansetron, 0.2 ul of ondansetron, 2 ul of ondansetron, 20 ul of ondansetron

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Ondansetron may alter whole blood coagulation. However, little is known about the dose-response relationships according to the blood concentration of ondansetron. The investigators therefore will perform the present study to measure the effect of ondansestron on the blood coagulation pathway according to the drug concentration level using a thromboelastography test.

Questions about this trial
What is this clinical trial studying?
A study testing 0 ul of ondansetron, 0.2 ul of ondansetron and 2 ul of ondansetron in people with Blood Coagulation Disorder, run by Seoul National University Bundang Hospital at 1 site in South Korea.
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 4 inclusion and 2 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: status not confirmed, as of the sponsor's last update on 15 Mar 2023. 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 South Korea. 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.

Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Hyo-Seok Na, MD., PhD. (82317877507, hsknana@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Citrated Functional Fibrinogen (time frame: During the thromboelastography analysis/ an average of 1 hour). 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 15 Mar 2023.
