Bioadhesive Polymeric Platforms for Transmucosal Drug Delivery Systems – a Review

Of the various routes of drug delivery, the oral route is often preferred by the patient. However, peroral administration of drugs has disadvantages such as hepatic first-pass metabolism and enzymatic degradation within the gastrointestinal tract which constitutes a hindrance to oral administration of certain classes of drugs, especially peptides and proteins. Consequently, other absorptive muc...

Polymeric Materials as Platforms for Topical Drug Delivery: a Review

With the emergence of novel and more effective drug therapies, increased importance is being placed upon the drug delivery technology. Topical formulations are attractive alternatives to oral formulations and offer several advantages, such as avoiding first-pass hepatic metabolism and gastric degradation. The major obstacle to drug delivery across the skin (transdermal) is the barrier nature of...

Transmucosal delivery systems for calcitonin: a review.

The commercial availability of peptides and proteins and their advantages as therapeutic agents have been the basis for tremendous efforts in designing delivery systems for such agents. The protection of these agents from biological fluids and physiological interactions is crucial for the treatment efficacy. One such agent is salmon calcitonin, a 32 amino-acid polypeptide hormone used in the tr...

A Review of Vesicular and Polymeric Nano-systems in Olanzapine Drug Delivery

 Olanzapine (2-methyl-4-(4-methylpiperazin-1-yl)-10H-thieno [2, 3-b][1, 5]benzodiazepine) is an antipsychotic drug with poor water-solubility that has a suitable affinity to some receptors. This benzodiazepine derivative is a new (atypical) antipsychotic drug and has a wide range of efficacy, especially in treatment of patients with negative psychiatric symptoms of schizophrenia. Olanzapine is ...
