Methotrexate-Polymer Nanocomposites for Targeted Pulmonary Drug Delivery
Nanocomposite formulation is a suitable technology that enables the development of successful dry powder inhalers. The methotrexate (MTX) and polyamide-disulfide (polymer) were used as a model to form MTX-polymer nanocomposites. Different amounts of the independent variable, MTX (0.025 and 0.050 g), polymer (0.05 and 0.01 g), pH (6.7 and 11.3), and across-linker ferric chloride (FeCl3) (0.05 and 0.10 g) were used. The loading efficiency and particle size were dependent variables. The optimized formula can be obtained with the highest loading efficiency and optimum particle size. This formula can be collected by using 0.025 g of drug, 0.079 g of polymer, 0.050 g of FeCl3, and pH = 6.7. The release of MTX from the nanocomposites occurs in two release steps; the first release step starts from the beginning up to 60 min, followed by a continuous release phase within 60 min. The results of the NGI analysis demonstrated that 28.1% of the nominated dose in each puff reached the lower parts of the respiratory system, an indication that the nanocomposites can be used in the delivery of MTX as a respiratory system.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
