Formulation and evaluation of chewable tablets of Desloratadine prepared by aqueous and non-aqueous techniques

Abstract

In the modern era, chewable tablets are preferred over conventional dosage forms by pediatric, geriatric and bedridden patients due to difficulty in swallowing, lesser amount of water for swallowing medications as well as unable to tolerate the bitter taste of certain drugs. Chewable tablets of Desloratadine (DS) were formulated by aqueous and non-aqueous granulation method using water paste and Isopropyl alcohol (IPA) as a wetting agents respectively. Desloratadine is used to treat the symptoms of allergy such as sneezing, watery eyes. In the recent research, we have formulated eight trials by various concentrations of excipients. For instance; lactose, talcum, magnesium stearate, blue color, flavor, aspartame, mannitol, avicel 101 and polyvenylpyrollidine (PVP). Pre-compression and post compression parameters (thickness, hardness, friability weight variation and drug content) of the formulations were evaluated. B3 was our optimum dosage form because its Hausner’s ratio, compressibility index, bulk density, tap density, angle of repose have optimum values i.e. 1.01, 5.1%, 0.66(g/cc), 0.69(g/cc), 26.1º respectively and post-compression i.e. thickness, hardness, friability weight variation and drug content have values, 2.9mm, 3.9(kg/cm²), 0.6%, 99.5% respectively. Tablets prepared by wet granulation technique showed reasonable release profile i.e. 100% within the required time i.e. 2 hours. Moreover, organoleptic evaluation of all formulations were performed.
