Exploring the effects of Maixuekang capsules on healthy volunteers

Exploring the Pharmacokinetics of Oligonucleotides in Maixuekang Capsules in Healthy Subjects

PHASE1 · Nanfang Hospital, Southern Medical University · NCT06823895

This study is testing how Maixuekang capsules affect healthy volunteers by looking at how certain substances in their blood change after taking the capsules.

What this trial studies

This clinical trial aims to investigate the sequence and expression levels of oligonucleotides in the plasma of healthy volunteers after administering Maixuekang capsules. Participants will be divided into two groups: one receiving a single dose and the other receiving multiple doses over three days. Blood samples will be collected at various time points to assess the pharmacokinetics of the oligonucleotides. The study focuses on understanding how these oligonucleotides behave in the body, which may provide insights into the drug's effects.

Who should consider this trial

Good fit: Ideal candidates for this study are healthy males and females aged 18 to 45 who meet specific weight and BMI criteria.

Not a fit: Patients with a history of thrombocytopenia, coagulation dysfunction, or bleeding tendencies may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the understanding of Maixuekang's pharmacokinetics, potentially leading to improved therapeutic applications.

How similar studies have performed: While this study explores a traditional Chinese medicine, similar pharmacokinetic studies have shown promise in understanding drug behavior, though this specific approach may be novel.
