HOT Article: Superior tableting from ionised amide groups

This HOT article reports the first salt form of acetaminophen, which is shown to have superior tableting properties relative to the stable polymorph of the unionised drug.  Amide groups are generally considered non-ionisable for the purposes of drug development and there are only a handful of  crystal structures with ionised amide groups known.  This success of forming an amide–hydrochloride salt using a simple experimental protocol may well encourage other research groups, both industrial and academic, to attempt salt formation with amides.
