Design of Fast Dissolving Oral Film of Lamivudine using Ion Exchange Resins Indion 204, Tulsion 335 and Doshion P551

Abstract

Ion exchange resigns are suitable for usage as flavor masking agents and sustained pharmaceutical release due to their inherent properties such as high ion exchangeability, modified administration capacity, physiochemical stability, and non-solubility in any solvent. Ion-exchange resins (IERs) are macromolecular polymers with differing cationic and anionic functional groups qualitatively as well as quantitatively. The polymer chain is fabricated in such a way that it consists of different salt-forming groups in repeating mode. In this study, we have tried to create a rapid dissolving oro-film of lamivudine using the ion exchange resins indion 204, tulsion 335, and doshion P551. FDOFs attempt to boost patient compliance by shortening the time it takes for the treatment to take effect, in addition to having a quick onset of action and higher bioavailability and also it’s a conventional dosage form. Out of three different resins, indion 204 gives a very excellent result with 1:1.5 ratio, where the maximum amount of complexation is within 4 hours of stirring. Their resinate are converted into granules and exhibit satisfactory value of angle of repose, bulk density, and flow property. Drug loading with indion 204 resin showed above 94%.”
