You were put in charge of designing new drug delivery systems in your company. your management gives you a lot of freedom in choosing a delivery platform (materials and methods). the only limitation you have is the conditions applied to the drug formulation. your current therapeutic agent has high lipophilicity and molecular weight of 1200 g/mol. also, it is prone to quick degradation in the presence of blood proteins and has high cytotoxicity in the free form. the company would like to design a delivery platform that allows for a peroral and targeted drug delivery with the circulation in the blood for at least 2 weeks. describe materials and methods that you would need to construct your system that satisfies all design criteria. keep in mind that materials used in delivery system formulation must be fda approved.
