A new bioanalytical liquid chromatography tandem mass spectrometric method has developed and validated for a
clinical determination of fingolimod hydrochloride in whole blood. The method has applied in bioequivalence study
following parallel open-label design, randomized single dose, and two treatments by healthy adult male subjects under
fasting conditions. Fingolimod with labeled Internal Standard (IS; Fingolimod-D4) was extracted from human blood
by liquid-liquid extraction and separated chromatographically from their matrix by Fortis UniverSil Cyano column.
The established method was validated over calibration dynamic range of 12-1200 pg/ml for spiked blood. In single
period, each subject of 42 healthy volunteer was received a single dose of 0.5 mg fingolimod hydrochloride capsule
of either the test or reference product. The pharmacokinetic parameters of C.. View more»
