Zeolites as Ingredients of Medicinal Products
Development of new medicinal products for particular therapeutic treatment or for better
manipulations with better quality and less side effects are possible as a result of advanced inorganic
and organic materials application, among which zeolites, due to their properties and versatility, have
been gaining attention. This paper is an overview of the development in the use of zeolite materials
and their composites and modifications as medicinal products for several purposes such as active
agents, carriers, for topical treatments, oral formulations, anticancer, the composition of theragnostic
systems, vaccines, parenteral dosage forms, tissue engineering, etc. The objective of this review is
to explore the main properties of zeolites and associate them with their drug interaction, mainly
addressing the advances and studies related to the use of zeolites for different types of treatments due
to their zeolite characteristics such as molecule storage capacity, physical and chemical stability, cation
exchange capacity, and possibility of functionalization. The use of computational tools to predict the
drug—zeolite interaction is also explored. As conclusion was possible to realize the possibilities and
versatility of zeolite applications as being able to act in several aspects of medicinal products
Incorporation of Brazilian Diatomite in the Synthesis of An MFI Zeolite
The need for greener procedures is a fact to reduce residues, to decrease industrial costs, and to accomplish the environmental agreements. In an attempt to address this question, we propose the addition of a natural resource, Brazilian diatomite, to an MFI zeolite traditional synthesis. We have characterized the resulting product with different techniques, such as X-ray diffraction, microscopy, and gas sorption, and, afterwards, we evaluate the greenness of the process by the Green Star method. The results were promising: We obtained the desired topology in the form of small crystallites aggregated and a pore diameter of 0.8 nm. In conclusion, the product has the necessary characteristics for an adsorption or catalytic future tests and escalation to industrial production
