Steroids Flashcards
S2Q2
STEROIDS: Corticosteroids
types (2), function (3)
- mineralcorticoids
- glucocorticoids
- fluid & electrolyte
- metabolism
- immune function
STEROIDS: Sex
testosterone effect #1 - (2)
testosterone effect #2 - (2.2)
testosterone effect #3 - (1)
ANDROGENIC
- enhance male secondary characteristic (bulk, mass)
ANABOLIC
- mass: hypertrophy (inc bulk), hyperplasia (inc cells)
- strength: inc Ca release from sarcoplasmic reticuluum, inc Ca sensitivity of contractile proteins
ERGOGENIC
- inc performance
STEROIDS:
anti catabolic effect (2)
catabolism sx (4)
ANTI-CATABOLIC EFFECT
- no breakdown
- proteolysis
CATABOLISM
- muscle weakness, wasting
- osteoporosis
- vertebral compression fx
STEROIDS: Cortisol Effects
glucose - main (2), glycogen what, what happens in liver (4), in other tissues (1.3) + where specific
inc in blood glucose & glycogen
- glycogen: blood in liver
- inc protein synthesis, glycogen synthesis, glycogen storage, gluconeogenesis (new sugar)
- other tissues: dec uptake & utilization of glucose (otherwise DM & Htn), inc lipolysis, inc proteolysis, inc fat deposition into abdominal adipose tissue
STEROIDS: Cortisol Effects
inflammatory - inhibit (3), vasowhat
anti-inflammatory
- inhibits eicosanoids (prostaglandin thromboxanes leukotrines), chemotaxin
- stabilize lysosomes: if breakdown = release inflammatory substances
- vasoconstriction = trap inflammation & less blood go there
STEROIDS: Cortisol Effects
immune - (4.3)
inhibit what pathway & therefore
enhance what (2) = (1) = (1)
— immune: BELM
immunosuppression
- dec: basophils, eosinophils, lymphocytes, monocytes
- inc: RBC, platelet, neutrophils
inhibit both cyclooxygenase & lipoxygenase pathway = better than NSAIDS & aspirin (only COX)
enhance Na & H2O reabsorption = fluid = edema
STEROIDS:
injection onset
days to weeks
STEROIDS: Adverse Effects
cushing’s sx (5)
- centripetal obesity
- hyperglycemia, Htn
- moon facie, buffalo hump
STEROIDS: Adverse Effects
adrenocortical suppression sx (9)
- anorexia, weight loss, nausea, vomit
- lethargy, headache, fever
- muscle & joint pain
- postural hypotension
STEROIDS: Adverse Effects
peptic ulcer - condition, pathology (1=1)
eyes (2)
other (2)
peptic ulcers
- gastritis
- inhibit COX1 = bye protective prostaglandin (aspirin)
- glaucoma: pressure in eyes
- cataract: clouding
- growth retardation
- delusion of persecution
STEROIDS: Preparation
short acting, intermediate, long - duration, example (1.2.1)
SHORT ACTING
- 8-12h
- corti
INTERMEDIATE ACTING
- 12-36h
- predni, lone
LONG ACTING
- 36-72h
- sone
STEROIDS: Neuropathic Pain
tricyclic antidepressants - drug + effect, side effect (5)
- ami: inc descending inhibitory
- anti-cholinergic side effects: drowsy, dry mouth, blur, constipation, diff urine
STEROIDS: Neuropathic Pain
anti-convulsant - drugs (4), side effects (4)
- pregabalin, gabapentin, carbamazepine, Na valproate
- side effects: dizzy, blur vision, stomach discomfort, fatigue
