A novel and sensitive method utilizing high performance liquid chromatography coupled with electrospray ionization source tandem mass spectrometry (LC-ESI-MS(3)) was developed for the first time in order to analyze nitrendipine in human plasma samples. Human plasma samples were prepared by
The present investigation was undertaken with the objective of developing a solid formulation containing nitrendipine nanocrystals for oral delivery. Nitrendipine nanocrystals were prepared using a tandem precipitation-homogenization process. Then, spray drying, a cost-effective method very popular in industrial situations, was
To investigate anti-solvent crystallization and growth mechanism of nitrendipine spherical crystals in an aqueous solution containing polymeric additives. Size and shape of crystals were investigated using laser diffractometry, optical microscopy and scanning electron microscopy (SEM). Crystalline form was determined by
In the past several years, the impact of changing counter ions while keeping the same anticoagulant in bioanalytical LC-MS/MS methods has become a highly discussed topic. In order to confirm that there is no impact from counter ions, matrix effect
