Delivery of peptides and proteins is critical for their clinical applications. Oral administration
of these molecules is not feasible due to degradation in the gastrointestinal tract. Peptides …

Peptides and proteins have been investigated as promising therapeutic agents over the past
decade. These macromolecules are conventionally administered by the parenteral route …

Transdermal delivery of peptides and proteins avoids the disadvantages associated with the
invasive parenteral route of administration and other alternative routes such as the …

Revolutionary advances in biotechnology have given rise to a large number of drugs that
are of peptide and protein origin. In order to reap the ultimate therapeutic benefits of these …

Peptides and proteins are gaining increasing importance as therapeutic agents. Oral
delivery of these molecules is not feasible due to gastrointestinal degradation. Parenteral …

Publisher Summary This chapter focuses on the enhancement techniques that aid the
transport of proteins and peptides through skin, so advancing their delivery. The skin is the …

The skin being the largest organ of the body presents a potential route for administration of
drugs. Passive transdermal products such as gels, creams and patches deliver drugs …

Human skin serves a protective function by imposing physicochemical limitations. For a drug
to be delivered passively via the skin it needs to have a suitable lipophilicity and a molecular …

Recently, a large number of new and potentially potent peptide and protein drugs have been
developed. Their systemic delivery is difficult because they are rapidly cleared from the …

INTRODUCTION Transdermal delivery offers an attractive option for the delivery of biodrugs
as it avoids first-pass degradation in the liver or gastro intestinal tract (GIT) and the skin …
