Effect of the characteristics of raw material ibuprofen on roller compaction and dissolution

Ibuprofen is an oral analgesic usually processed by wet granulation. In this manuscript a new roller compaction process for ibuprofen is reported. The low melting point of ibuprofen is a critical point to be considered during processing. Melting of ibuprofen and its posterior solidification leads to a lower soluble form. The hypothesis of this work is that crystallinity of ibuprofen may be a good indicator of the quality for both raw material...
