| Popis: | In drug formulation development cyclodextrins (CD) are well known for their ability to complex hydrophobic compounds. They are widely used to enhance the solubility of an active pharmaceutical ingredient (API) with the benefit of masking a possible unpleasant taste. Maltodextrins (dextrose equivalent: MD1–17 and MD2–13) with a high amylose content have very similar molecular properties but are mainly used for nutritional supply. This study compared the solubilizing and taste-masking capacities of two new MD grades to well-established water-soluble CD. We used two poorly soluble APIs, dextromethorphan hydrobromide and loperamide hydrochloride, to compare the effects of CD and MD on solubility. The addition of either 5 mM CD or MD to an oversaturated API solution increased solubility of both dextromethorphan hydrobromide (CD: +9.77%, MD1: +19.55%, MD2: +24.40%) and loperamide hydrochloride (CD: +47.43%, MD1: +75.34%, MD2: +112.27%). These APIs are described as being of bitter taste. The taste-masking effects of CD and MDs on dextromethorphan HBr, loperamide HCl and the highly soluble cetirizine HCl were evaluated through electronic taste sensing systems (e-tongues). These systems based on potentiometric mechanism are equipped with different types of sensor membranes to distinguish between different taste attributes of investigated samples. Bitterness sensor results were analyzed with principal component analysis, which allows a relative scoring of API complexes. The analysis revealed better masking capability of CD for cetirizine HCl (CD These results indicate a better effect of MDs on solubility compared to CD for all tested APIs and possible better taste-masking properties of MDs compared to CD for some APIs. We conclude that the use of MDs presents a promising new approach for developing drug formulations. |
