Gellan Gum/Alginate Microparticles as Drug Delivery Vehicles: DOE Production Optimization and Drug Delivery
نویسندگان
چکیده
Gellan gum is a biocompatible and easily accessible polysaccharide with excellent properties to produce microparticles as drug delivery systems. However, the production methods often fail in reproducibility, compromising translational potential of such In this work, gellan gum-based was optimized using coaxial air flow method, an inexpensive reproducible method. A design experiments used identify main parameters that affect microparticle optimization, focusing on diameter dispersibility. Airflow most significant factor for both parameters. Pump affected diameter, while gum/alginate ratio Microparticles were revealed be sensitive pH swelling, degradation, encapsulation efficiency by pH. Using methylene blue model drug, higher encapsulation, swelling indexes obtained at 7.4, more pronounced release occurred 6.5. Within PBs solutions, endured up two months. The profiles studied well-known models, showing Fickian-type release, but no alteration developed showed promising results drug-delivery vehicles

Nerve guidance channels (NGCs) have been shown to facilitate regeneration after transection injury to the peripheral nerve or spinal cord. Various therapeutic molecules, including neurotrophic factors, have improved regeneration and functional recovery after injury when combined with NGCs; however, their impact has not been maximized partly due to the lack of an appropriate drug delivery system...

Many strategies have been proposed to explore the possibility of exploiting gastroretention for drug delivery. Such systems would be useful for local delivery, for drugs that are poorly soluble at higher pH or primarily absorbed from the proximal small intestine. Generally, the requirements of such strategies are that the vehicle maintains controlled drug release and exhibits prolonged residenc...
