Drug deliveryDrug delivery refers to approaches, formulations, manufacturing techniques, storage systems, and technologies involved in transporting a pharmaceutical compound to its target site to achieve a desired therapeutic effect. Principles related to drug preparation, route of administration, site-specific targeting, metabolism, and toxicity are used to optimize efficacy and safety, and to improve patient convenience and compliance. Drug delivery is aimed at altering a drug's pharmacokinetics and specificity by formulating it with different excipients, drug carriers, and medical devices.
BMP (facteur de croissance)Bone morphogenetic proteins (BMPs) are a group of growth factors also known as cytokines and as metabologens. Originally discovered by their ability to induce the formation of bone and cartilage, BMPs are now considered to constitute a group of pivotal morphogenetic signals, orchestrating tissue architecture throughout the body. The important functioning of BMP signals in physiology is emphasized by the multitude of roles for dysregulated BMP signalling in pathological processes.
Targeted drug deliveryLa délivrance de médicament ciblée, parfois appelée administration de médicaments « intelligents », est un procédé d'administration de médicament qui vise à augmenter la concentration du médicament dans certaines parties du corps par rapport aux autres. L'objectif de cette administration est de prolonger, localiser, cibler et avoir une interaction protégée entre le médicament et le tissu malade. Le système conventionnel de délivrance de médicament est l'absorption du médicament à travers une membrane biologique, alors que le système de libération ciblée libère le médicament sous une forme de dosage unitaire.
