This study gives information about the formulation of β-cylcodextrin nanosphere by emulsification solvent-evaporation method based on emulsifying an organic phase containing the β-cylcodextrin in an aqueous phase of pluronic-F68 as surfactant. The nanospheres are loaded with hydrophobic drug and the in-vitro drug release study was conducted. The formulation of colloidal particle was associated with amphiphilic properties of the β-cylcodextrin derivatives. However, the partitioning of the β- cyclodextrin between the organic and aqueous phases is always depends on the concentration of the surfactant. In the case of nanospheres loaded with Irinotican hydrochloride, the partitioning of the drug occurs between the dispersed phase containing β- cylcodextrin and the continuous aqueous phase containing pluronic-F68.Keywords

Buccal drug delivery offers a safe and easy method of drug utilization, because drug absorption can be promptly terminated in case of toxicity by removing the dosage form from the buccal cavity. A buccal film for systemic administration of diclofenac sodium has been developed using hydroxyl propyl methylcellulose, poly vinyl pyrolidone, glycerin, eudragit and ethanol by solvent casting method. The prepared films characterized by means of film thickness, swelling capacity, in- vitro adhesion, drug release, weight variation, folding endurance, etc. The in vitro release studies were conducted for diclofenac sodium patches in phosphate buffer-pH-6.6 solution. The mechanism of release is diffusion process followed by first order kinetics. The formulated patches exhibit drug release in the range of 76.92 to 92.12% in four hours.Keywords
