• Abstract:

  Backgrounds

  In oral controlled release formulations using ethyl cellulose (EC) and hydroxypropyl cellulose (HPC) coatings, the drug release behavior is governed by the phase structure of the water soluble HPC component. The number of d

  Aims

  We have applied the paramagnetic relaxation enhancement (PRE) solid-state Nuclear Magnetic Resonance (ss-NMR)
