E1 - Corticosteroids Flashcards
corticosteroids are derived from
synthetic versions of endogenous hormones from the adrenal cortex portion of the two adrenal glands
corticosteroids used for
anti-inflammatory effects
hormone secreted by anterior pituitary
adrenocorticotropic hormone (ACTH) also referred to as corticotropin
ACTH stimulates the
adrenal gland to release corticosteroids
2 classes of adrenocorticosteroids
glucocorticoids and mineralocorticoids
glucocorticoids
cortisol and cortisone; effects glucose metabolism, protein and lipid metabolism, effecting inflammation
mineralocorticoids
aldosterone; water and electrolyte balance and metabolism, retention of Na and excretion of K+
structure of CS
four ring steroid structure (functional groups attached to pentanu
uses of CS
HRT, Anti-inflammatory and immunosuppressive effects, hormonal regulation of the expression of genes, anti-allergic
immunosuppressive effects
suppress response, especially involving lymphocytes
SLE (lupus)
chronic autoimmune and inflammatory disease, especially in skin and organs, can be treated by adjunctive therapy and CS
neoplastic uses of CS
used primarily in advanced cancers
metabolic effects of CS
increased blood glucose and insulin secretion, muscle protein catabolism, lipolysis and lipogenesis
anabolic steroids
“olone”s involved in the synthesis and buildup of protein
steroids other than “olones”
are catabolic in nature
