|Drug Delivery Systems, Film Coating Technology, Drug-excipient interactions|
1. Drug Delivery Systems: Conventional as well as Modified Release for both solid and liquid oral dosage forms
2. Film Coating Technology: Enteric, controlled and sustained release as well as conventional coating development and applications. The newly developed coating methods of dry (solventless) coating are also of interest.
3. Interaction of Excipient materials with actives and with other additives and their effect on pharmacokinetics and pharmacodynamics of drugs.
