The aim of this manuscript is to study cyclodextrins (CDs) as a potential excipient to suppress bitterness and enhance palatability of pediatric liquid preparations for Cetirizine, an extremely bitter drug. Natural α, β and γ CDs; and β CD derivatives such as hydroxyl propyl (HP), randomly methylated (RM) and sulfobutyl ether (SBE) β-CDs were screened in different molar ratios of 1:1, 1:2 and 1:3 for their inhibition of the extremely bitter taste of Cetirizine using the human gustatory sensation test. Cavity size and chemical substitution are dominantly two factors that affect Cetirizine inclusion into natural CDs and β CD derivatives respectively. Syrup and drops formulations were prepared based on the selected α-, γ -and RM β-CDs.
