Undesirable taste is an important problem for patient compliance. Several oral pharmaceuticals
and bulking agents have disagreeable and bitter-tasting components. The Bitter taste characteristics
found in such systems have been eliminated or minimized by the development of numerous formulations
with improved performance and acceptability especially in children and elderly patient. This review
is mainly concerned with the bitter-masking techniques published in peer-reviewed journals and
will shed light on different methods of masking undesirable taste of the drugs, and their pharmaceutical
applications. Hence, nearly no reference will be made to the techniques published as patent applications.
Keywords: Bitter compounds, taste masking, sweeteners, taste suppressant, coating techniques, polymers.
