- glaucoma
- Renal failure
What are the pharmacological action of corticosteroids
- Carbohydrate, Lipid, protein metabolism
- Electrolyte in water metabolism
- calcium metabolism
- increase hypertension CVS
- required for normal function of skeletal muscle
- CNS effects
- G.I. effects
- blood and lymph
- tissue anti-inflammatory effect
- immuno suppressant effect
Which drugs do not promote electricity and water Metbolism
- Dexamethasone
- betamethasone
- triamcinolone
What are the effects of Glucocorticoids on calcium metabolism
- Inhibit calcium absorption
- increase renal excretion
- inhibit osteoblasts
- increases osteoclast activity
What are the effects of glucocorticoids on Skeletal muscles in increased and decreased scenarios
- Hypercortisolism - do to inadequate circulation
- Hypercortisolism: do to hyperkalaemia
What are the indirect CNS actions of corticosteroids
Maintenance of:
1. blood pressure
2. blood glucose concentration
3. electrolyte levels
How do Glucocorticoids Act on GIT
1. Inhibits Prostaglandins and increases gastric acid and pepsin secretion Can lead to peptic ulcer.
2. Decrease local immune response against H. pylori
What are the anti-inflammatory effects of glucocorticoids
1. Induce lipocortin What’s your name it’s phospholipase A2. Which inhibits the formation of PG, LT’s and PAF
2. Production of cytokines like IL-1, IL-6 and TNF alpha are inhibited 
3. Stabilize lysosome membrane and prevent release of inflammatory mediators
4. inhibit the production of various adhesion molecules
What are the effects of glucocorticoids on the immune system and lymphoid tissue
- Decrease in lymphocytes, eosinophils, basophils and monocytes
- Inhibit B cells and T cells functions
- Suppress all hypersensitivity reactions
What are the adverse effects of Glucocorticoids
- Metabolic effects such as hyperglycaemia, hyperlipidaemia
- Cushing’s habitus
- G.I. peptic ulcers with haemorrhage or perforation 
- Salt and water retention which can lead to CCF
- Muscle weakness and fragility
- Osteoporosis
- growth retardation
- Glaucoma and cataracts
- CNS changes
- immunosuppression
- HPA axis suppression 
Which glucocorticoids may precipitate growth retardation in children
- dexamethasone
- betamethasone
What are the therapeutic uses of glucocorticoids (replacement therapy)
- Acute renal insufficiency
- Chronic adrenal insufficiency
- Adrenogenital syndrome and adrenal virilism 
What are the uses of glucocorticoids(non-endocrine diseases)
- Rheumatoid arthritis
- osteoarthritis
- gout
- rheumatic fever
