Novel Drug Delivery Strategies: New Concepts

The biopharmaceutical performance of an existing drug molecule can be significantly improved through its evolution from a conventional form to a novel delivery system. Apart from biopharmaceutical performances, the safety, efficacy and patient compliance are also improved for a drug molecule. Present day drug delivery companies are emphasizing prominently on development of multiple platform technologies for getting competitive merits, expand patent span, and enhance market share of their products. The quantum of novel drug delivery products has significantly increased in the past few years, and this growth is expected to continue in the near future. Today large numbers of companies are busy developing protein and peptide based drug molecules due to advancement in the field of genomics which in turn accelerated research of biopharmaceuticals. Due to the unique nature of biopharmaceuticals it is difficult to deliver them by conventional routes and this presents challenges to the drug delivery scientists. Therefore, present research is focusing on the delivery of these complex molecules through different routes including oral, nasal, pulmonary, vaginal, rectal, buccal, colon specific, etc. [1].
