In Brazil, the 1946 Constitution enshrined the right to health, having it defined as the possession of the best state of health that the individual can achieve. Already the Federal Constitution of 1988 lifted that right to the status of fundamental social right, which transcends the effectiveness and cure of the disease is based on the joint liability of public entities for the provision of a quality service, efficient and prioritize human dignity and comprehensive evaluation of patients. According to the World Health Organization, the definition of health, first characterized as the mere absence of disease, has become recognized as the need to search for preventive mechanisms to ensure the welfare and dignity of the population. Garantista this context, the growing seem lawsuits that deal with the implementation of public policies, especially in the area of the right to health, the omission of which the Government can result in the risk of death. Hence the concern of law professionals about whether or not the intervention of the judiciary in cases that deal with providing material benefits of health care. It claims to break the principle of separation of powers, disobedience to the principle of equality and the impossibility of judicial intervention in the formulation of public policy to try and exclude the liability of public entities. In contrast, the judiciary has repeatedly guardianships granted injunctions or merit determining the supply of materials indicated by the medical benefits that accompany the treatment of patients who resort to a remedy. In this context, mediation, object of study and resolution presented in this work, is presented as an instrument conciliator between the reserve clause and the right to financially possible existential minimum, as it seeks to serve all through rationalization of health services , avoidance of negativistic influence of the pharmaceutical industry, with prioritizing the welfare of the individual and the quality of relationships. This is alternative way to judicialization that in addition to encouraging and developing active citizen participation in public policy formulation also allows the manager to public knowledge of community needs. It is in this sense that affirms and defends the right to health is no longer the mere provision of medical care and prescription drugs, but a dialogue conscious existential minimum to guarantee a dignified life

This thesis was devoted to the development of innovative oral delivery systems for two different molecules. In the first part, microparticles (MPs) based on xylan and Eudragit® S- 100 were produced and used to encapsulate 5-aminosalicylic acid for colon delivery. Xylan was extracted from corn cobs and characterized in terms of its physicochemical, rheological and toxicological properties. The polymeric MPs were prepared by interfacial cross-linking polymerization and spray-drying and characterized for their morphology, mean size and distribution, thermal stability, crystallinity, entrapment efficiency and in vitro drug release. MPs with suitable physical characteristics and satisfactory yields were prepared by both methods, although the spray-dried systems showed higher thermal stability. In general, spraydried MPs would be preferable systems due to their thermal stability and absence of toxic agents used in their preparation. However, drug loading and release need to be optimized. In the second part of this thesis, oil-in-water microemulsions (O/W MEs) based on mediumchain triglycerides were formulated as drug carriers and solubility enhancers for amphotericin B (AmB). Phase diagrams were constructed using surfactant blends with hydrophiliclipophilic balance values between 9.7 and 14.4. The drug-free and drug-loaded MEs presented spherical non-aggregated droplets around 80 and 120 nm, respectively, and a low polydispersity index. The incorporation of AmB was high and depended on the volume fraction of the disperse phase. These MEs did not reduce the viability of J774.A1 macrophage-like cells for concentrations up to 25 μg/mL of AmB. Therefore, O/W MEs based on propylene glycol esters of caprylic acid may be considered as suitable delivery systems for AmB
