The adhesive strength of film-coated tablets of fillers without drug was found to slightly decrease after storage. In contrast, the adhesive strength of drug-containing film-coated tablets significantly reduced, the degree of which was higher for Eudragit E100® than HPMC. Physicochemical characterization by employing differential scanning calorimetry (DSC) and diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) revealed that the drug was obviously incompatible with lactose and possibly mild interaction with Eudragit E100® was suggested. The results indicated that the adhesive strength of film-coated tablets would be affected not only by the drug-excipient interaction, but also by the drug-polymeric film interaction.225 KBapplication/pdfengMahidol UniversityFilm-Coated TabletsDrug-Excipient InteractionDrug-Polymer InteractionAdhesive StrengthRanitidine HCIHydroxypropyl MethylcelluloEudragit E100Research ArticleTaylor and Francis (available from Informa HealthCare)10.1080/03639040500528962
