FORMULATION AND EVALUATION OF ARCHIMEDES BASED NOVEL FLOATING CAPSULE THROUGH FILM FORMATION AND RETENTION FOR DRUG DELIVERY OF LEVOFLOXACIN
AbstractThe study objectives were to develop a unique expandable integrated floating film to be filled in capsule dosage form, which combines hydrophilic and hydrophobic polymers. The developed film was totally free from the concept of gas generating system or the low-density system, which floats merely due to Archimedes principle. A 32 full factorial design was used in the study with HPMC K100M (X1) and ethylcellulose cp10 (X2) as independent variables and time required for dissolution of drug and swelling as dependent variables. FTIR and DSC studies were carried out to investigate any drug excipient interaction. The XRD studies of formulation showed decreased crystallinity of the drug levofloxacin. Steady slow gel formation and the higher concentration of ethylcellulose, resulted in sustained drug release. The hydrophilic polymer readily expands the polymeric network within two hours. The predicted value of 90.419 and the actual drug release from the polymeric film were closely related to each other.
