  • present invention refers to pharmaceutical industry
  • namely to a method for producing stable nanosuspension
  • various nanosuspensions for long-term stability were tested. An accelerated stability test was performed in an analytical centrifuge (Lumifuge from LUM GmbH
  • Germany) to classify and quantify separation phenomena
  • such as precipitation (sedimentation)
  • flotation
  • or nanosuspension consolidation. This test was used to determine the stability of nanosuspension. It is believed that nanosuspension has long-term stability if sedimentation
  • or consolidation of nanoparticles are absent or are observed to a very small extent. above-described suspension is stable and effective for treating or preventing a disease specified in cancer and inflammatory bowel disease
