<abstract xmlns="http://www.w3.org/1999/xhtml"><p> Objective: The aim of this study is to develop lactose-free orodispersible tablets with loratadine for patients with lactose intolerance. Materials and methods: Seven compositions (F1-F7) of 10 mg loratadine were prepared in form of orally disintegrating tablets, by direct compression, using croscarmellose sodium and pre-gelatinized starch in various concentrations as superdisintegrants, diluted with microcrystalline cellulose and combined with mannitol and maltodextrin as binder agents. The tablets had been studied in terms of their pharmacotechnical characteristics, by determining: the weight uniformity of the tablets, their friability, breaking strength and disintegration time, drug content and the dissolution profile of loratadine. The statistical analyses were performed with GraphPad Prism Software Inc. As dependent variables, both the hardness of the tablets and their disintegration ability differ between batches due to their compositional differences (as independent variables). DDSolver were used for modeling the kinetic of the dissolution processes by fitting the dissolution profiles with time-dependent equations (Zero-order, First-order, Higuchi, Korsmeyer-Peppas, Peppas-Sahlin). Results: All proposed formulas shows rapid disintegration, in less than 15 seconds, and the dissolution loratadine spans a period of about 10 minutes. Akaike index as well as R2 adjusted parameter have demonstrated that the studied dissolution profiles are the best fitted by Zero-order kinetic. Conclusion: In conclusion, association of croscarmellose sodium (7.5%) with pre-gelatinized starch (6%) as superdisintegrants and mannitol as the binder agent (35%), positively influences the dissolution properties of loratadine from orally fast dispersible tablets.</p></abstract>
