Resumo
This work aims to ascertain the comprehensiveness of dissolution tests for oral suspensions
registered in Brazil and the USA. After consulting literature since 1994, a paucity of information
about dissolution methods for suspensions was detected. It makes it difficult to establish the
most appropriate test parameters. In January, 2019, there were 46 drugs registered in Anvisa
(Brazil) as oral suspension, being 47 reference, 173 generic and 114 interchangeable similar
(IS) medicines; while in the USA, 90 drugs were registered as oral suspension by FDA, 235
Abreviatted New Drug Application and 111 New Drug Application medicines. Out of 46 and 90,
only six and 15 drugs as oral suspension had a pharmacopeial dissolution test, corresponding
to 70 (20.9%) and 82 (23.7%) products in Brazil and the USA, respectively. Dissolution studies
were found for 17 drugs as oral suspension in the non-compendial literature. Dissolution test
conditions were established to few marketable oral suspension drugs, most of which are BCS
class II or IV. Thus, investing in dissolution studies could subsidize the registration of these
products by regulators, especially for generic and IS drugs, by comparing dissolution profiles,
and predicting their in vivo behavior to avoid exposure of healthy individuals to clinical research.
