Príspevok je zameraný na formulácia antihistaminika loratadínu do hydrogélov. Hodnotenými polymérmi boli Carbopol® 980 a Vivastar® P 5000. Nakoľko nevyhnutnou súčasťou hydrogélov sú aj ďalšie farmaceutické pomocné látky zo skupiny humektantov, príspevku sa hodnotí ich vplyv (glycerolu – GL, propylénglykolu – PG a sorbitolu – SO) na štruktúrnu viskozitu a pH hydrogélov a aj farmaceutickú dostupnosť loratadínu. Na základe výsledkov štúdie sa môže konštatovať, že z hľadiska dermálnej aplikácie sú pre loratadín optimálne hydrogély následovného zloženia: 0,5% Carbopol® 980 + 5% SO a 1,5 % Vivastar® P 5000 + 5 % PG.
