ClinConnect Summary

This clinical trial is looking at a medication called Zhibitai capsules to see if taking a higher dose can help people with primary hyperlipidemia, a condition where there are high levels of fats in the blood. The study will compare taking two capsules twice a day to the original dose of one capsule once a day. The goal is to understand whether the higher dose is more effective and safe for patients.

To participate in this trial, individuals need to be between 18 and 75 years old and have specific levels of fats in their blood. They should also agree to follow a healthy diet and exercise routine during the study. Participants will be asked to keep a diary of their health and medication use. It's important to note that some people, such as those with certain medical conditions or on specific medications, may not be eligible to join. This trial is not yet recruiting participants, but it will provide valuable information about how Zhibitai can help manage cholesterol levels in the future.
