Flashcards in Analgesics and Anti-inflammatories - Steroids (1) Deck (8):
1

Which compound do steroids inhibit?

Phospholipase. This prevents the conversion of membrane phospholipids into arachidonic acid, and thereby prevents the production of arachidonic acid metabolites such as leukotrienes and prostaglandins.

2

What is the difference between cortisol and hydrocortisone?

Hydrocortisone is the pharmaceutical preparation of cortisol. Cortisol is a naturally-occurring hormone.

3

From which compound is cortisol synthesized?

Cholesterol (just like the androgens and the mineralocorticoids)

4

How much of cortisol is excreted unchanged in urine?

Only 1%.

5

Give an overview of how steroids inhibit inflammation.

- Multiple inhibitory effects on the recruitment and function of leukocytes
- Reduction of leukotriene, platelet-activating factor and prostaglandin synthesis.

6

Name a drug with mineralocorticoid action given orally.

Fludrocortisone.

7

Name two long-acting glucocorticoid drugs.

Dexamethasone, Betamethasone.

8

Name as many adverse effects of long-term steroid use as you can.

Moon facies, hirsutism, acne, insomnia, increased appetite, hyperglycaemia, weight gain, muscle wasting, thinning of the skin, striae, bruising, osteoporosis, impaired wound healing, peptic ulcers.
