Interaction of probenecid with the protein binding of methotrexate.

Abstract:

:The effect of probenecid on the plasma protein binding of methotrexate (MTX) has been examined in vitro. At concentrations greater than or equal to 5 x 10(-4) M, probenecid caused a significant reduction (greater than 30%) in the plasma binding of MTX. It is suggested that in vivo this would lead to a greater dispersion into the tissues and a larger volume of distribution, and may be partly responsible for the longer MTX elimination half-life observed with concurrent administration of probenecid.

  • Accumulation of norepinephrine (NE) by rat organs in vivo.

    abstract::In anesthetized rats intravenously infused, norepinephrine (NE) was accumulated by the heart, the spleen and the lung in a dose-related manner. With the lower dose of NE (2.5 mg/kg) the organ/blood ratios were more than unity and were generally greater than with higher doses (5 and 10 mg/kg), indicating that accumulat...
