Popis: The release behavior of doxycycline hyclate (DH) from beta-cyclodextrin (β-CD) in situ gels (ISG) and in situ microparticles (ISM) was investigated using dialysis tube method and direct contact method compared to that from DH solution. From dialysis tube method, DH released completely from solution within 8 h, while it released with more sustainable from ISM and ISG completely at 12 h and 28 h, respectively. The release pattern of them was similar when tested using direct contact method (released completely at 9 days). The DH release from dialysis tube method of all systems was a first order kinetic. DH release from ISM using direct contact method fitted well with a Higuchi’s equation. The dialysis tube method was suitable for determining formula factors affecting the drug release behavior. However, to simulate the pocket condition with contact area is limited, the drug release test with direct contact method was preferred than dialysis tube method.
