Title: GLUCOCORTICOIDS AND MINERALOCORTICOIDS
1GLUCOCORTICOIDS AND MINERALOCORTICOIDS
2Corticosteroids
- Adrenal glands produce glucocorticoids and
mineralocorticoids - Glucocorticoids
- Involved in cholesterol, fat, and protein
metabolism
3Corticosteroids
- Adrenal glands produce glucocorticoids and
mineralocorticoids - Glucocorticoids
- Involved in cholesterol, fat, and protein
metabolism - Mineralocorticoids
- Involved in regulating electrolyte and water
balance
4Cortisol
- Principal adrenal steroid hormone
- Responsible for
- Gluconeogenesis
- Protein catabolism
- Anti-inflammatory reactions
- Stimulation of fat deposition
- Sodium and water retention
5Corticosteroids
- Adrenal hormones excluding sex hormones
- Steroid production follows a circadian rhythm
6Properties of glucocorticosteroides used in
clinics
- Anti-inflammatory
- Immune-depressive
- Anti-allergic
- Anti-shock
- Anti-toxic
7Anti-inflammatory action of GCS
- Nonspecific inflammation
- Auto-immune component
- Hyperergic character
- Therapy of despair
8Mechanism of anti-inflammatory action of GCS
GCS
activation of lipomoduline
decreasing of activity of phospholipase ?2
slowing down of arachidonic acid metabolites
production (prostaglandins, leucotriens,
thromboxan ?2)
stabilization of cellular and lyzosomal membranes
decreasing of capillaries wall permeability
decreasing of leucocytes migration processes,
depression of phagocytes activity
depression of histamine, serotonin,
bradykinine releasing
9Indications for administration of GCS
- Insufficiency of adrenal cortex
- Rheumatoid illnesses (rheumatoid arthritis,
rheumatism, system red lupus etc.) - Chronic active hepatitis
- Bronchial asthma
- Ulcerative colitis
- Nephritic syndrome
- Auto-immune hemolytic anemia
- Shock and collapse of any etiology
- Brain, lungs, larynx edema
- Acute allergic reactions
- Transfusion reactions
- Heavy infections (hiding behind the etiotropic
drugs!) - Liver disesaes
10Doses and terms of GCS therapy
Situation Daily dose Terms of treatment
Acute cases (shock, collapse, brain, lungs edema, septic shock, asthmatic condition etc.) 200-500- 800-1000 mg i.v. 1-3 days
Subacute and acute attacks of chronic processes (rheumatoid diseases, ulcerative colitis, bronchial asthma etc.) 20-50 mg (rarely till 200 mg) 4-6 weeks- several months
Primary and secondary insufficiency of adrenal cortex 2,5-10 mg life-long
11Corticosteroids
- Act as anti-inflammatory and immunosuppressive
agents in treating diseases of different origins - Hematologic
- Allergic
- Inflammatory
- Neoplastic

disorders - Available in many different dosage forms
16Problems with Corticosteroids
- Lessen the ability of leukocytes to destroy
infection which decreases fever, redness, and
swelling - Also may cause infection to spread
17Corticosteroid Dispensing Issues

uncontrolled hypertension, CHF, severe infection
or altered immunity, or peptic ulcer disease with
active GI bleeding

infection - May be painless and patient may be unaware
- Fluid in the sores is highly infectious
- Bacteria enters the bloodstream and lymphatic
system
74Secondary-Stage Infection

and mild fever - Symptoms subside after a few weeks and disease
becomes latent - After 2-4 years of latency, the disease is
usually no longer infectious
