The invention concerns a system for biocompatible drug release comprising: (i) a polymer matrix; (ii) an inorganic component located inside said matrix and characterized by a lamellar structure with a net positive or negative charge able to intercalate (iii) a pharmacologically active principle into said lamellar structure, by establishing an ionic type of bond with it and thereby obtaining an intercalation compound. The preparation process for the release system comprises the stages of: treating the lamellar solid in such a way as to give it a net positive or negative charge, then combining it with the chosen active principle, also in an ionic form, to obtain an intercalation compound which is then mixed with the polymer matrix. The release system can be employed in making medical devices, like sutures, membranes, osteosynthesis plaques, multilayered devices, gels and drug delivery systems.

Controlled-delivery system of pharmacologically active substances, preparation process and medical use thereof

This invention relates to a composite material for biomedical applications, in particular dental applications, which possesses self-healing capacity and is able to incorporate a system for the release of active ingredients at the stage of application and use.

Composite material with properties of self-healing and release of active ingredients, for biomedical applications

A process is for preparing a self-healing composite material including a matrix of epoxy polymer in which a catalyst of ring opening metathesis reaction and vessels containing at least one monomer able to polymerize due to a ring opening metathesis reaction are dispersed. The process includes the preliminary step of dispersing at molecular level the catalyst in a mixture containing at least one precursor of the epoxy polymer, and then the steps of dispersing, in the mixture, the vessels and a tertiary amine acting as curing agent of the precursor, and the step of curing the mixture by at least a first heating stage performed at a temperature between 70 and 90&#xb0; C. for a time between 1 and 5 hours, and a second heating stage performed at a temperature between 90 and 170&#xb0; C. for a time between 2 and 3 hours.
