Oral drug delivery systems (DDS)

• multiparticuate DDS
  
  • pelletization ({extrusion/spheronization}, rotorgranulation)
  • minitablets
  • coating
  • compression of pellets into tablets
• pulsatile DDS (tablets, capsules, pellets)
• gastroretentive DDS
• matrix tablets (water-soluble and - insoluble carriers)
• fast dissolving dosage forms (tablets, sponges, films, capsules)
• delivery of poorly soluble drugs
• formulation of moisture-sensitive drugs

Coating technology

• aqueous polymer dispersions
• aqueous/organic polymer solutions
• coating with natural polymers (e.g., shellac, zein)
• coating of pellets, tablets, soft and hard gelatin capsules
• polymer powder coating

Microencapsulation

• micro-/nanoparticles (solvent evaporation, spray drying, grinding, {SCF})
• incorporation micro-/nanoparticles into a final dosage form
• liquid controlled release DDS

Biodegradable DDS

• implants (melt compression, extrusion)
• microparticles
• in-situ microparticle/ implant system
• lipid DDS (cubic phase DDS, microparticles)
• delivery systems for larger molecules (proteins, peptides, oligonucleotides)

Miscellaneous projects

• mucoadhesive DDS (nasal, buccal)
