Development and characterization of mucoadhesive buccal gels containing lipid nanoparticles of ibuprofen.

The lipid nanoparticles, namely Nanostructured Lipid Carriers (NLC), as drug delivery systems have been investigated for several years. One of the delivery routes for which these carriers can be applied is buccal administration. However, the liquid dispersions of lipid nanoparticles can be rapidly removed from oral cavity by saliva.

Nanotechnological carriers for cancer chemotherapy: the state of the art.

Cancer is a term used for a heterogeneous group of malignant diseases in which abnormal cells divide without control and are able to invade other tissues, resulting in metastasis. According to the last data of World Health Organization the incidence and mortality rates of cancer are high and tend to increase. Chemotherapy is usually used in cancer treatments, but due to the lack of specificity of drugs, is associated to various and damaging side effects that have a severe impact on patients quality of life.
