Quiz 6 (Anti Inflammatory) Flashcards
Inflammation
Body’s response to injury
What is the purpose for inflammation?
Intended to be a protective mechanism
What are some clinical signs of inflammation? (3)
- Redness and heat
- Swelling and edema
- Pus
What can excessive or prolonged inflammation impair and cause?
can impair the healing process and cause pain to the animal
Corticosteroids
Hormones produced by the adrenal gland
What are the two types of cortico steroids produced?
- Mineralocorticoids
2. Glucocorticoid
What do Mineralocorticoids do?
regulate mineral levels in the body
what do Glucocorticoids do?
exert an anti-inflammatory effect, but also have many other effects in the body
How is the production of corticosteroid regulated?
Feedback inhibition mechanism
what are the biologic effects of glucocorticoids in the body?
- Decrease inflammation
- Inhibit scar tissue formation
- Suppress the body’s immune system
- Affect the cellular blood count
- Increase gastric acid secretion and decrease mucus production in GIT
- Increase protein breakdown
- Can induce parturition
- Increase blood glucose levels
What can an overuse of glucocorticoids lead to?
disease
How do glucocorticoid drugs differ?
Products currently used differ in duration of effect and dosage form available
What is the duration of the effect of short acting glucocorticoids?
What are some examples? (2)
biologic effect lasts < 12 hrs.
- hydrocortisone
- cortisone
What is the duration of the effect of intermediate-acting glucocorticoids?
What are some examples? (3)
effect lasts 12-36 hrs.
- prednisone (prednisolone)
- triamcinolone
- methylprednisolone
What is the duration of the effect of Long-acting glucocorticoids?
What are some examples? (3)
effect lasts more than 48 hrs.
- dexamethasone
- betamethasone
- flumethasone
What are the dosage forms available with glucocorticoids? (3)
- topical preparations
- oral
- injectable products
What are the glucocorticoid parenteral formulations? (3)
- Aqueous solutions
2. Alcohol solutions
How are aqueous glucocorticoid solutions made?
the glucocorticoid is combined with salt and dissolved in water
How are aqueous glucocorticoid solutions administered?
can be given in large doses intravenously w/ less risk of an adverse reaction
what are some examples of aqueous glucocorticoid solutions
- dexamethasone sodium phosphate (Azium),
2. prednisolone sodium succinate (Solu-Delta Cortef)
How are Alcohol glucocorticoid solutions made?
glucocorticoid is dissolved in alcohol
What happens when alcohol glucocorticoid solutions are administered IV?
adverse reaction
How are glucocorticoid Suspensions made?
the glucocorticoid is suspended in a liquid vehicle
What are some examples of glucocorticoids suspension?
- methylprednisolone acetate (Depo-Medrol)
2. triamcinolone acetonide (Vetalog)
How must glucocorticoid suspensions be stored?
store at room temperature
What must happen before use of glucocorticoid suspensions?
must be shaken before use
