About this study

Official title: A Pharmacokinetic Study of Glucosamine and Chondroitin

The purpose of this study is to examine the way the dietary supplements glucosamine and chondroitin are absorbed and distributed throughout the body.

Read the detailed description

Osteoarthritis is the most common musculoskeletal disease in the world. While predisposing conditions have been identified, the actual cause of osteoarthritis remains unknown. Traditional treatments, most often anti-inflammatory drugs and pain relievers, produce variable results and may cause significant toxicity. The use of complementary and alternative therapies in the treatment of osteoarthritis has become more common, and particular interest has focused on glucosamine and chondroitin treatments. This study will examine the pharmacokinetics of glucosamine and chondroitin.

This study consists of two phases. In Phase I, participants will have two study visits, during which multiple blood samples will be taken to determine levels of glucosamine and chondroitin found naturally in the body. During Phase II, participants will be randomly assigned to receive glucosamine, chondroitin, or a combination of the two for 3 months. Blood samples will be taken at each of the three Phase II study visits to examine the pharmacokinetics of glucosamaine and chondroitin.

Where is the study taking place?

The record lists 1 site in United States. 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

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?
