- Farmaceutická fakulta Univerzity Komenského v Bratislave, Katedra galenickej farmácie
The paper focuses on the formulation of the antihistamine loratadine for hydrogels. In the first stage of this study, the evaluated polymer for the preparation of hydrogels was Carbopol® 980 of concentrations of 0.5, 0.8, and 1.0 %. The paper aimed to determine the optimal concentration of Carbopol® 980 in hydrogel formulation on the basis of the evaluation of the rheological properties and biological availability of loratadine from prepared hydrogels. The results of the study show 0.5% hydrogel of Carbopol® 980 to be optimal for loratadine from the standpoint of topical administration.
Keywords: hydrogels; Carbopol® 980; loratadine; liberation; rheological properties
