Q

What is exposure and response prevention (ERP)?

A

ERP is a psychological method which involves exposing a patient to an anxiety provoking situation (e.g. for someone with OCD, having dirty hands) and then stopping them engaging in their usual safety behaviour (e.g. washing their hands). This helps them confront their anxiety and the habituation leads to the eventual extinction of the response

Q

What is the mechanism of action of opioids?

A

Opioids work via the endogenous opioid system by acting as a potent agonist to the μ receptor. This results in a complex cascade of intracellular signals resulting in dopamine release, blockade of pain signals, and a resulting sensation of euphoria.

By blocking the cotransporter, they also reduce sodium reabsorption → natriuresis reduces intravascular volume and blood pressure, but it also increases the delivery of sodium to the macula densa → normalises tubuloglomerular feedback and thereby reduces intraglomerular pressure
