Inhibiteur de la recapture de la sérotonine et de la noradrénalineLes inhibiteurs de la recapture (ou du recaptage) de la sérotonine-noradrénaline (IRSNa, IRSN ou SNRI en anglais pour Serotonin-norepinephrine reuptake inhibitor) sont des psychotropes qui inhiberaient de façon sélective la recapture de la noradrénaline et de la sérotonine. Cette inhibition entraîne une augmentation de la concentration synaptique de ces neuromédiateurs. Dans un délai de quelques semaines, on pense qu'une diminution adaptative ("down regulation") des récepteurs postsynaptiques 5HT2A à la sérotonine et β postsynaptiques à la noradrénaline, récepteurs qui seraient , se produit.
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.
Molecular medicineMolecular medicine is a broad field, where physical, chemical, biological, bioinformatics and medical techniques are used to describe molecular structures and mechanisms, identify fundamental molecular and genetic errors of disease, and to develop molecular interventions to correct them. The molecular medicine perspective emphasizes cellular and molecular phenomena and interventions rather than the previous conceptual and observational focus on patients and their organs.
