โฆ Synopsis
A rapid and specific method has been developed for the determination of orphenadrine concentration in plasma. It involves a one-step sample preparation using n-hexane/isopropyl alcohol (98 : 2) extraction, and analysis by gas chromatography on a wide bore capillary column using nitrogen/phosphorus detection. This procedure considerably simplifies previously reported assays and is specific and sensitive enough for the determination of orphenadrine in plasma of patients on chronic therapy.

However, there were significant correlations between the enthalpy involved and each of VAG maximum viscosity, breakdown, viscosity at 50 ยฐC and set back (r = 0.53, P < 0.05; r = 0.49, P < 0.05; r = 0.62, P < 0.05; r = 0.65, P < 0.01, respectively). For RVA data, correlations were found only between
