The invention relates to the technical field of medical medicines, in particular to a taste-masking oral suspension containing 3-boryl-L-
phenylalanine and a preparation method of the taste-masking oral suspension. Each 100 mL of the taste-masking oral suspension is prepared from the following components: 4 to 6 g of 3-boryl-L-
phenylalanine, 8.5 to 17.5 g of beta-
cyclodextrin, 0.08 to 0.12 g of
stevioside, 0.03 to 0.08 g of lemon essence, 0.25 to 0.35 g of
xanthan gum and 0.08 to 0.12 g of
potassium sorbate. On the basis of an intermolecular hydrophobic interaction principle, a
benzene ring bitter group of 3-BPA is specifically included by utilizing a hydrophobic cavity of beta-
cyclodextrin, so that taste
perception is reduced; natural
stevioside (free of heat and dental caries risk) and lemon essence (capable of covering residual peculiar smell) form a synergistic taste-masking
system, and the synergistic taste-masking
system is matched with a
xanthan gum suspending aid to prepare a uniform suspension; the preparation has the core advantages that the characteristic of high water
solubility (125 g / L) of 3-BPA is fully utilized, the preparation does not need to add any solubilizer, taste optimization, stability improvement and
swallowing convenience
adaptation are synchronously realized, and three core requirements of'
curative effect, safety and compliance 'of medication for children are considered.
