Sažetak	Solid dispersion is a formulation technique where a poorly soluble drug is molecularly dispersed in a hydrophilic polymer matrix, improving aqueous solubility and bioavailability. Introduced by Chiou and Riegelman in 1971, solid dispersions remain a key strategy for overcoming solubility-limited absorption.	The Caco-2 assay is an in vitro model system using human colon carcinoma cell monolayers to screen drug intestinal permeability. Developed by Hidalgo and colleagues in 1989, Caco-2 cells differentiate into an epithelial barrier resembling intestinal mucosa, enabling rapid assessment of drug absorption potential and identification of transporter-mediated transport.	The f1 and f2 factors are dimensionless statistical measures developed by Moore and Flanner to quantify the similarity between two dissolution profiles. Adopted by regulatory agencies (FDA, EMA) as the gold standard for comparing dissolution curves, these factors enable rapid assessment of whether formulation changes significantly impact drug release.
