Taste Masking Challenge of 150 APIs

The same is true for developing palatable formulations – it’s not enough to know that it tastes “yucky” as there’s no universal “yummy” excipient.

Do Excipients Affect Drug Taste? A Guide to Taste Masking Challenges.

Posted by David Tisi on May 5, 2019

An estimated 80% of new drug actives are classified as poorly soluble.

Like APIs, many excipients are known to be bitter or have other aversive sensory attributes including aromatic off-notes (malodor) and trigeminal irritation (e.g., tongue sting and mouth or throat burn). In some cases, the taste masking challenge of the excipient system can be greater than for the API itself.

Try this experiment next time you are in a coffee shop: Open a packet of artificial sweetener (pink, yellow, or blue) and pour it directly on your tongue. Yuck! That tasted nothing like a spoonful of sugar – so what happened? Though artificial sweeteners are widely used in pharmaceuticals, formulating with them is far from straightforward.
