On Physical Nature of the Long-Range Effect during the Crystal Growth through Boundary Layers
A mechanism of the long-range effect in the processes of crystal growth through boundary layers based on the study of the nature of the chemical bond between the deposited and surface atoms is proposed. It is shown that the spatial distribution of the probability of finding a negative binding charge (i.e. its density) cannot be considered strictly fixed between the nearest neighboring ion cores.
Reduction of Bitterness and Enhancing Palatability of Cetirizine Oral Liquid Dosage Forms by Cyclodextrins
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.
