Simultaneous HPLC Assay of Paracetamol and Sulfapyridine as Markers for Estimating Gastrointestinal Transit of Amphotericin B-containing Nanoparticles in Rat Plasma


A simple and sensitive two-step reversed-phase HPLC method was developed and validated for determining amphotericin B, paracetamol and sulfapyridine in rat plasma using piroxicam as internal standard. This was subsequently employed in a pharmacokinetic study in rats following simultaneous oral administration of solid lipid nanoparticle formulations of… (More)
