Poly(lactic-co-glycolic acid) (PLGA) is one of the most successful polymers used for producing therapeutic devices, such as drug carriers (DC). PLGA is one of the few polymers that the Food and Drug Administration (FDA) has approved for human administration due to its biocompatibility and biodegradability. In recent years, DC produced with PLGA has gained enormous attention for its versatility in transporting different type of drugs, e.g., hydrophilic or hydrophobic small molecules, or macromolecules with a controlled drug release without modifying the physiochemical properties of the drugs. These drug delivery systems have the possibility/potential to modify their surface properties with functional groups, peptides, or other coatings to improve the interactions with biological materials. Furthermore, they present the possibility to be conjugated with specific target molecules to reach specific tissues or cells. They are also used for different therapeutic applications, such as in vaccinations, cancer treatment, neurological disorder treatment, and as anti-inflammatory agents. This book aims to focus on the recent progress of PLGA as a drug carrier and their new pharmaceutical applications.

Current controlled release formulations has many drawbacks such as excess of initial burst release, low drug efficiency, non-degradability of the system and low reproducibility. The present project aims to offer an alternative by developing a technique to prepare uniform, biodegradable particles (~19 æm) that can sustainably release a drug for a specific period of time. Chitosan is a natural polysaccharide that has many characteristics to be used for biomedical applications. In the last two decades, there have been a considerable number of studies affirming that chitosan could be used for pharmaceutical applications. However, chitosan suffers from inherent weaknesses such as low mechanical stability and dissolution of the system in acidic media. In the present study, chitosan microparticles were prepared by emulsification process. The model drug chosen was acetylsalicylic acid as it is a small and challenging molecule. The maximum loading capacity obtained for the microparticles was approximately 96%. The parameters for the preparation of uniform particles with a narrow size distribution were identified in a triangular phase diagram. Moreover, chitosan particles were successfully coated with thin layers of poly lactic-co-glycolic acid (PLGA) and poly lactic acid (PLA). The performance of different layers was tested for in vitro drug release and degradation studies. Additionally, the degradability of the system was evaluated by measuring the weight loss of the system when exposed to enzyme and without enzyme. Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), atomic force microscopy (AFM) and inductively coupled plasma optical emission spectrometry (ICP-OES) were used to characterize the controlled release system. Additionally, the in vitro drug release was monitored by ultraviolet-visible spectrophotometry (UV-Vis) and liquid chromatography mass spectrometry (LC-MS). The results obtained from this project showed that it is possible to prepare biodegradable microparticles with a uniform size distribution and high drug loading efficiency. However, this could only be achieved with a hybrid system consisting of chitosan matrix interior and then exterior coating of PLGA or PLA. A two layer coating of PLGA 50:50 was shown to be optimal with sustainable controlled drug release for almost 5 days and with 91% of degradation (weight loss) in 8 weeks.
