ClinConnect Summary

The Timed Aspirin Chronobiome Study is a clinical trial designed to see if taking aspirin at specific times can help reduce the effects of another medication called celecoxib on blood pressure. This study is for healthy adults aged 18 and older, but it particularly aims to include those aged 65 to 74. To participate, individuals must be in good health, with controlled blood pressure and cholesterol levels, and they should not have any serious health conditions or allergies to aspirin or celecoxib.

Participants in the study will need to go through a screening process to ensure they meet the eligibility criteria, which includes providing informed consent and undergoing some medical tests. They will also need to avoid certain medications and supplements before joining the trial. The study has not yet started recruiting participants, but once it does, those who qualify can expect to learn more about how the timing of aspirin might affect their blood pressure while also contributing to important medical research.
