Webb5 jan. 2024 · The median tVPA was 43.5 mg/L (27.4–63.6), with measured fVPA 9.1 mg/L (4.5–14.7) and calculated fVPA 10.1 mg/L (7.0–13.0), respectively. The median deviation of calculated from measured fVPA was −0.8 mg/L … WebbAt therapeutic concentrations, over 90 % of VPA in the circulation is bound to plasma proteins, primarily albumin. Binding is saturable, and at high VPA concentrations, the free fraction increases. Other compounds can compete for VPA binding to albumin; these include salicylic acid and free fatty acids.
