Q

What are the effects of GCs?

A

Widespread effects on carb, protein, and lipid metabolism, and electrolyte/water balance.

in the nervous system:
Excess GC = insomnia/euphoria followed by depression, aka steroid psychosis.

Q

What is the MOA of a GC’s antinflammatory/immune effects?

A

Inhibits production of precursors to prostaglandins, leukotrienes, and PAF.

Suppresses inflammatory cytokines, chemokines, and other inflammatory mediators.

Inhibits macrophages and other APCs

Reduces synthesis of arachidonic acid, which leads to reduction of COX 2, reducing prostaglandins.

Reduces antibody production in large doses.

Note:
NSAIDs are also COX inhibitors.
