Polymeric Biomaterial and Lipid Based Nanoparticles for Oral Drug Delivery.

Abstract: Background Oral drug delivery is widespread owing to its non-invasive nature which complements high patient compliance. However, the drug administration via oral route is quite challenging due to the presence of the biochemical barriers which hinders the uptake as well as access to blood stream. Apart from that, stability, poor solubility and bioavailability of administered drug via the gastrointestinal (GI) tract are also exigent. Till now various oral formulations were developed which releases the drug in a timely manner but lacks appropriate therapeutic concentration. Objective Recently nanoparticles based drug delivery system has emerged as prominent strategy for optimizing the oral drug delivery and maximizing the treatment efficiency. Besides, different strategic polymeric nanoparticles are engineered for interaction both at extracellular and intracellular levels with gastrointestinal mucosa. Methods The review article focuses on the polymeric and lipid based various nanocarriers that have been widely studied for the enhanced oral drug delivery of different therapeutic molecules and addresses recent progress of biocompatible and biodegradable polymeric nanoparticles approach for its improvement. Conclusion The progress of numerous oral nanoparticulate drug delivery vehicles will be immensely helpful to improve therapeutic efficacy with reduced adverse side effects. Unlike other forms of administration, it will have better patient compliance and soothing effect. The oral drug delivery will certainly play a pivotal role soon in expanding the clinical repertoire and applications.

Abstract: A UV-protective water-soluble polyaminoamide comprising UV-absorbing end groups, wherein the polyaminoamide absorbs ultraviolet light radiation having a wavelength of about 200 nm to about 420 nm, compositions comprising the UV-protective polyaminoamide and methods of treating substrates with the UV-protective polyaminoamide.

Polymer solution preparation system

Abstract: A POLYMER SOLUTION PREPARATION SYSTEM FOR PROPORTIONALLY ADDING A POLYMER-CONTAINING EMULSION TO WATER CONTAINING A SURFACTANT TO INVERT THE EMULSION AND RELEASE THE POLYMERS INTO THE WATER AS A SOLUTION INCLUDING A MIXING TANK AND A HOLDING TANK TOGETHER WITH PUMPS FOR PUMPING PREDETERMINED AMOUNTS OF POLYMER-CONTAINING EMULSION AND SURFACTANT INTO THE MIXING TANK AND MIXING SAME WITH A PREDETERMINED QUANTITY OF WATER TO PRODUCE THE POLYMER SOLUTION THAT IS THEN TRANSFERRED TO THE HOLDING TANK. INSTRUMENTATION IS PROVIDED FOR AUTOMATICALLY BATCHING THE POLYMER SOLUTION IN THE MIXING TANK AND TRANSFERRING THE SOLUTION TO THE HOLDING TANK SO THAT A SOLUTION SUPPLY IS MAINTAINED IN THE HOLDING TANK FOR FEEDING A LIQUID SYSTEM.
