BACKGROUND The production of protein drugs has recently increased due to advances in biotechnology, but their clinical use is generally limited to parenteral administration due to low absorption in non-parenteral administration. Therefore, non-parenteral delivery systems allowing sufficient absorption draw much attention. METHODS Microparticles (MP) were prepared using chitosan-4-thio-butylam...

Peptide and protein drugs have found an important position in therapeutics. Recent advances in pharmaceutical biotechnology have led to an increase in the number of protein products in the market. As these therapeutic proteins and peptides are made available, it will be essential to formulate these drugs into safe and effective delivery systems. The twenty different naturally occurring amin...

Although oral delivery has become a widely accepted route of administration of therapeutic drugs, the gastrointestinal tract presents several formidable barriers to drug delivery. The delivery of drugs to the colon has a number of therapeutic implications in the field of drug delivery. In the recent times, the colon specific delivery systems are also gaining importance not only for local drug d...

background: different methods have been used for bcg vaccination. alginate microspheres are useful in delivery of vaccines to the gastrointestinal tract by oral route. objective: to compare the immune response following oral microencapsulated and subcutaneous (sc) route administration of bcg vaccine in balb/c mice. methods: alginate microspheres were produced by an internal emulsification metho...

background: the aim of this study was to measure the concentrations (levels) of serum total proteins and advanced oxidation protein products as markers of oxidant mediated protein damage in the sera of patients with oral cancers. methods: the study consisted of the sera analyses of serum total protein and advanced oxidation protein products’ levels in 30 age and sex matched controls, 60 patient...

Despite a better understanding of the pathogenesis of oral cancer, its treatment outcome remains poor. Thus, there is a need for new therapeutic strategies to improve the prognosis of this disease. RNA interference (RNAi) appears to be a promising therapeutic tool for the treatment of many diseases, including oral cancer. However, an obstacle for RNAi-mediated therapies has been delivery, in pa...

Drug delivery technologies have the potential to enable drug candidates with poor pharmaceutical or biopharmaceutical properties, both for macromolecule and traditional compounds. While there have been many success stories to date, the future offers even more promise. In this article, the author surveys the top ten areas in drug delivery looking forward. William J. Lambert, PhD, is the senior v...
