Notes:
Summary The effect of low doses of heparin on the binding of phenytoin and prazosin to plasma proteins was evaluated in four normal subjects. Heparin activates the hydrolysis of triglycerides in plasma. The ensuing increase in non-esterified fatty acids (NEFA) was more marked in vitro than in vivo and increased the free fraction (FF) of phenytoin and prazosin in plasma. The higher FF caused a change in the plasma to whole blood ratio (P/B ratio) of both drugs. The changes in FF and P/B ratio after heparin were small, but could be of significance in pharmacokinetic studies.
