Glucocorticoid therapy Flashcards
(glucocorticoids/mineralocorticoids) have anti-inflammatory and immunosuppressant effects?
Glucocorticoids
(glucocorticoids/mineralocorticoids) regulate renal sodium and water reabsorption and potassium excretion
Mineralocorticoids
Fludrocortisone acetate has high (glucocorticoid/mineralocorticoid) activity
Mineralocorticoid
Why is hydrocortisone unsuitable for disease suppression on a long term basis?
Fluid retention (due to relatively high mineralocorticoid activity)
Exception: adrenal replacement therapy in Adrenal insufficiency
Prednisolone has predominantly (glucocorticoid/mineralocorticoid) activity with minimal (glucocorticoid/mineralocorticoid) effects
- Glucocorticoid
- Mineralocorticoid
Prednisolone is the corticosteroid most commonly used by mouth for long-term disease suppression
Betamethasone and dexamethasone have very high (glucocorticoid/mineralocorticoid) activity in conjunction with insignificant (glucocorticoid/mineralocorticoid) activity.
- Glucocorticoid
- Mineralocorticoid
This makes them particularly suitable for high-dose therapy in conditions where fluid retention would be a disadvantage
Some esters of betamethasone and beclomethasone exert a considerably more marked (oral/topical) effect than when given (orally/topically)
- Topical
- Orally
Use is made of this to obtain topical effects whilst minimising systemic side-effects
Deflazacort has high (glucocorticoid/mineralocorticoid) activity
Glucocorticoid
It is derived from prednisolone
What are the indications for the use of beclometasone dipropionate? (5)
- Management of oral ulceration
- Prophylaxis of asthma
- Prophylaxis and treatment of allergic and vasomotor rhinitis
- Severe inflammatory skin disorders (eczamas unresponsive to less potent corticosteroids, psoriasis)
- Adjunct to aminosalicylates in acute mild to moderate ulcerative colitis
What are the contraindications for all systemic corticosteroids? (3)
- Avoid injections containing benzyl alcohol in neonates
- Avoid live virus vaccines in those receiving immunosuppressive doses (serum antibody response diminished)
- Systemic infection
What are the contraindications for all topical corticosteroids? (5)
- Acne
- Perioral dermatitis
- Potent corticosteroids in widespread plaque psoriasis
- Rosacea
- Untreated bacterial, fungal or viral skin lesions
When are systemic corticosteroids prescribed to the elderly potentially inappropriate (STOPP criteria)?
- If used instead of inhaled corticosteroids for maintenance therapy in moderate to severe COPD
- As long-term (>3 months) monotherapy for rheumatoid arthritis
- For treatment of osteoarthritis other than for periodic intra-articular injections for monoarticular pain
- With concurrent NSAIDs without PPI prophylaxis
What are the common side effects for inhaled corticosteroids?
- Headache
- Oral candidiasis
- Pneumonia (in patients with COPD)
- Taste altered
- Voice alteration
What can be used with a corticosteroid inhaler to reduce the risk of oral candidiasis? (2)
- Spacer device
2. Rinsing mouth with water after inhalation of a dose
If a patient using an inhaled corticosteroid get oral candidiasis and is treated with an anti-fungal oral suspension or oral gel, do they need to stop the corticosteroid therapy?
NO
An anti-fungal oral suspension or oral gel can be used to treat oral candidiasis without discontinuing corticosteroid therapy.
Paradoxical (?) is an uncommon side effect of inhaled corticosteroids
bronchospasm
What can be used to prevent mild paradoxical bronchospasm in a patient taking inhaled corticosteroids?
Short-acting beta-2 agonist inhaler before the corticosteroid
Moderate to severe paradoxical bronchospasm requires discontinuation and alternative therapy
What are the common side effects of intranasal corticosteroids? (6)
- Altered smell sensation
- Epistaxis
- Headache
- Nasal complaints
- Taste altered
- Throat irritation
What is a rare but serious uncommon side effect of intranasal corticosteroids?
Glaucoma
What are the common side effects of topical corticosteroids?
- Skin reactions
2. Telangiectasia
Do inhaled corticosteroids for asthma need o be stopped during pregnancy?
NO
Take as normal during pregnancy
Should systemic corticosteroids be stopped during pregnancy?
Not usually
The benefit of treatment with corticosteroids during pregnancy outweighs the risk
Corticosteroid cover is required during labour
What needs to be monitored in pregnant women taking systemic corticosteroids?
Fluid retention
Do intranasal and systemic corticosteroids need to be stopped during breastfeeding?
NO
Benefits outweigh risks
