I really enjoyed reading your article, it was very informative and detailed. I will like to share additional insight I found interesting too.

According to Berg and Clarke (2018), Agonists have intrinsic efficacy (the ability to increase the activity of a receptor), and inverse agonists are said to have negative intrinsic efficacy (the ability to decrease the activity of a receptor). Just as agonist intrinsic efficacy for a receptor varies with the structure of the agonist (resulting in strong agonists and weaker [partial] agonists), inverse agonists also have different degrees of negative intrinsic efficacy, resulting in strong and weak (partial) inverse agonists.

Inverse agonists are ligands that selectively bind to the inactive state of the receptor (Kenakin, 2017). If any receptor happens to be in an active state spontaneously, then an inverse agonist will reverse the resultant constitutive activity. However, the main pharmacological effect of inverse agonists is receptor antagonism, that is, inverse agonists will block the effect of agonists and the effect on constitutive activity is only relevant if the system is spontaneously active (Kenakin, 2017). There is a property of inverse agonists that may be therapeutically relevant in nonconstitutively active systems (Kenakin, 2017).

As a psychiatric mental health nurse practitioner, it is essential for you to have a strong background in foundational neuroscience. In order to diagnose and treat clients, you must not only understand the pathophysiology of psychiatric disorders, but also how medications for these disorders impact the central nervous system. These concepts of foundational neuroscience can be challenging to understand. Therefore, this Discussion is designed to encourage you to think through these concepts, develop a rationale for your thinking, and deepen your understanding by interacting with your colleagues.
