Novel Carrier Systems for Targeted and Controlled Drug Delivery
Presents novel carrier systems for the targeted and controlled drug delivery for the treatment of various diseases which are difficult to be treated with conventional drug delivery systems like cancer, autoimmune disorders, and emerging infectious diseases. It also reviews the origins and applications of stimuli-responsive polymer systems and polymer therapeutics such as polymer-protein and polymer-drug conjugates. The book also explores the potential applications of the parenteral route of administration for the delivery of active pharmaceutical substances with a narrow therapeutic index and poor bioavailability. Further, the book presents common routes of administration for the systemic delivery of peptides and proteins. It also examines the applications of various implantable systems in drug delivery. The book also covers the important colloidal drug delivery systems, including liposomes and niosomes and solid lipid nanoparticles, and nanostructured lipid carriers.
Drug delivery via nasal route
Over the past 10 years, the interest in intranasal drug delivery has increased. The objective of this research is to summarize recent developments on intranasal administration for local and systemic delivery, as well as for CNS indications. Nasal delivery offers many advantages over standard systemic delivery systems, nevertheless, there are still formulation limitations and side effects to be optimized. Intranasal drug delivery in the field of drug development is an interesting delivery route for the treatment of neurological disorders. Systemic approaches often fail to efficiently supply the CNS with drugs. This research describes the anatomical, histological and physiological basis and summarizes currently approved drugs for administration via intranasal delivery. Further, the research focuses on advantages and disadvantages of intranasal applied compounds and discusses formulation aspects that need to be considered for drug development.
Bigel : An innovative drug delivery system
Bigel is a promising drug delivery system that modifies the pharmacotherapeutic characteristics of knowing active pharmaceutical ingredient (API).It is a mix between hydrogel and organogel (oleogel). The objective of the present work demonstrates the ability of bigel to overcome the disadvan- tages of both types of gels, including the limited ability to cross lipophilic barriers of the skin for hydrogels and the low patient compliance for organogels due to their stickiness and oily residues. Materials andmethods : Carbomer934, PolyvinylpyrrolidoneK 90 and Castor oil where mixed in a high shear mixer using diferent weight percentages of each. Hence,13 for mulations (BG1 to BG13) prepared by simplex mixture design modelis used to study the inuenceofafore- mentioned ingredients on appearance, dynamicviscosity, pH, stability, microscopicstructure of bigel and to understand the chemical interactions between bigel components, Fouriertrans- form infrared (FTIR) analysis will bereported.
