  5. Nasal delivery of peptides using powder carriers based on starch/poly(acrylic acid)

    Pringels, E2006

    As peptides are not suitable for oral administration, they are generally administered parenterally. Due to the disadvantages associated with parenteral delivery alternative routes of administration (buccal, nasal, pulmonal, ocular, transdermal, rectal and vaginal route) have been investigated. In …
