Non-destructive crystallinity assessment of indomethacin in tablets made from smartFilms(R) using terahertz time-domain spectroscopy
We use terahertz (THz) time-domain spectroscopy (TDS) to assess the crystalline state of indomethacin (IM) when loaded in smartFilms®. We found that smartFilms favour the amorphous IM (A-IM) for low loading concentrations. For higher concentrations, IM recrystallizes in its α- crystalline form and t...

| Zusammenfassung: | We use terahertz (THz) time-domain spectroscopy (TDS) to assess the crystalline state of indomethacin (IM) when loaded in smartFilms®. We found that smartFilms favour the amorphous IM (A-IM) for low loading concentrations. For higher concentrations, IM recrystallizes in its α- crystalline form and the amount of A-IM in the smartFilms reduces. Both, α- and A-IM are preferred over the more common γ- crystalline form, as they exhibit better water solubility, which can increase the oral bioavailability of the drug. |
