title: Concentration of azapropazone in synovial tissues and fluid.
abstract: The concentration-time curves of azapropazone in synovial fluid and tissues have been studied in arthritic patients after an i.v. bolus (600 mg) and under steady-state conditions. Synovial fluid and tissue samples were taken intraoperatively 0.45-60 h after administration. The azapropazone concentrations in synovial fluid, synovial tissue and plasma were correlated. The levels in synovial fluid were usually lower than corresponding plasma levels. Under steady-state conditions azapropazone did not accumulate in synovial tissues.
