ClinConnect Summary

This clinical trial is exploring how potassium citrate, a medication that helps make urine less acidic, might lower uric acid levels and reduce gout flare-ups. Gout is a painful condition caused by high levels of uric acid in the body, which can lead to painful swelling in the joints. The study compares two groups receiving potassium citrate or sodium bicarbonate with a control group that is only getting standard treatment for gout. Researchers hope to find out if these treatments can also help prevent kidney stones in people with gout.

To participate in this study, you need to be between 18 and 70 years old and have been diagnosed with gout according to specific guidelines. You should not have had a gout flare for at least two weeks and must be on stable doses of uric acid-lowering medications for at least four weeks. Participants will take potassium citrate or sodium bicarbonate three times a day. It’s important to note that there are several health conditions and circumstances that could prevent someone from joining, such as severe heart issues or being pregnant. If you are interested in joining, you will need to provide informed consent and attend regular visits for check-ups and treatments throughout the study.
