Total and Free Plasma and Total Synovial Fluid Piroxicam Concentrations: Relationship to Antiinflammatory Effect in Patients with Reactive Arthritis and Other Arthritides
Abstract:Twenty-five patients (14 males, 11 females), sixteen with reactive arthritis and 9 with other arthritides were treated with piroxicam, 40 mg at day 1 and 20 mg daily the following 9 days. Both local knee joint and general disease activity were assessed at day 0 and day 10. At day 10, plasma and synovial fluid were drawn. Total and free (determined after equilibrium dialysis) plasma concentrations and total synovial fluid concentrations were measured by HPLC. Total plasma piroxicam concentrations (micrograms/ml… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
