metabolized to prednisolone- dosage exchangable with a functioning liver.
|
|
If you have liver issues but want to use a steroid?
|
Use, prednisilone -- doesn't have to go thru the liver. Made especially for animals!
|

Solu-Medrol) IV Less sodium retention-
For trauma patients Oral tablets ( acetate) ( about 2/3 dosage of prednisolone |
|
Name the best anti-inflammatory:
|
Flumethasone
|
|
Celestone is ½ acetate ½ Na phosphate, is it long acting or quick?
|
Slow release, not fast acting!
|
|
Name the anabolic steroids used in horses?
|
Equipose- Boldenone- approved in horses, not for stallions or pregnant mares dues to absence of data.
|
|
What is Equipose used for?
|
to reverse tissue depleting processes and restore constructive metabolism. Anabolic therapy is intended primarily as an adjunct to other specific and supportive therapy, including a high protein diet.
|
|
What is Nandrolone ( Durabolin)?
|
Anabolic steriod - human product
used in small animals- for refractory anemia. Now use erythropoetin as a replacement |
|
general effect of anabolic steroids?
|
stimulation of the erythropoiesis process.
|
|
What is the adverse effect that occurs from use of prednision/prednisilone ?
|
Adrenal glands will atrophy so that when the medication is discontinued, animal unable to respond to stressful situation. Circulatory crisis can result.
Use the medication every other day, this allows the body's own adrenal glands to remain active |
|
Can we use corticosteroids for the eye?
|
Yes. Topical application can cause systemic side effects. Prednisolone acetate 1.0% and dexamethasone 0.1% are the best choices for corneal and anterior uveal diseases. Most systemic steroids penetrate the blood-aqueous barrier and are used to treat intraocular inflammations.
Dexamethasone/prednisolone |
|
How do we use corticoisteriods in small animal opthalamology?
|
Decrease cellular infiltration, inhibit fibroblastic and collagen-forming activity, retard epithelial regeneration, diminish neovascularization, and stabilize lysosomes.
Can cause increased intraocualar pressure Cataracts in cats? |
|
Adverse effects of glucocorticoids -
|
Glucocorticoid hormones can cause abortion in pregnant patients.
Never use at same time as NSAIDS Spinal trauma, (solumedrol) and then switch to anti-inflammatory ??? Solumedrol is short acting, so you can then switch to anti-inflammatory Steroids are contraindicated in head trauma / |
|
Effects of steroid withdrawl?
|
Dullness
Depression Decreased exercise tolerance In-cordination Weight loss Loose stools Behavior changes – can become vicious! |
|
Steriods in diabetic patients?
|
Steroid-associated insulin resistance can make pre-existing diabetes much harder to treat, and can tip stable diabetics over into a diabetic crisis. Even the relatively minor systemic absorption of topical steroids, such as steroid eye drops or skin creams, can be enough to have an effect on diabetic control.
|
|
Glucos?
|
High dose has been a controversial issue in the treatment of hypovolemic shock
Inhibit the arachidonic acid cascade, while beneficial for decreasing cellular inflammation, can result in gastric ulceration and bleeding via inhibition of cyclooxygenase-1 formation. Hypoxic-induced gastrointestinal mucosa may be further damaged by corticosteroid therapy, even after 1 or 2 doses. |
|
Contradictions of glucocorticosteriod use?
|
Infectious disease
Diabetes mellitus Liver disease Protein-losing nephropathy Pregnancy…may induce abortion/congenital defects Inhibit growth in immature animals Wound or fracture healing inhibited No corticosteroid in eye with infection/corneal ulceration=risks corneal perforation/delay repair/2nd infection |
|
Best times to use glucocorticoids?
|
Documented shock from Addisonian crisisAsthma attacksBad itchy skin dogs??IBDChronic active hepatitisLymphomaUveitis
|
|
Adverse effects of glucocorticoids?
|
Metabolic: diabetes mellitus, hyperlipidemia, hepatopathy
Musculoskeletal: muscle atrophy, ligament weakness Immunosuppression: increased risk of infection and septicemia Endocrine: hypothalamo/pituitary axis suppression, thyroid and parathyroid suppression GI: gastric ulcers, pancreatitis Fluid balance: water retention, PU/PD Anaphylactic reactions Abortion |
|
Metabolic effects of glucocorticoids?
|
glucocorticoids raise blood glucose through increasing gluconeogenesis and antagonizing insulin. They also alter protein and fat metabolism.
|
|
Antiinflammatory effects?
|
inhibits arachidonic acid formation leading to prostaglandin, thromboxane, and leukotrienes. Can also neutrophil migration into tissue and increase membrane stability.
|
|
Effects on water balance?
|
increase in glucose and/or sodium can osmotically increase plasma volume, often resulting in PU/PD (especially in dogs).
|
|
CNS effects?
|
: steroids can improve mood, behavior, and appetite, but may lower seizure threshold.
|
|
Immunosupression?
|
at high doses, the anti-inflammatory effects resulting from altered leukocyte movement and function can become immunosuppressive.
|
|
GI?
|
ulcerogenic due to increased secretion of gastric acid, pepsin, and trypsin. This effect is synergistic with NSAIDs.
|
|
Adrenal axis supression:
|
exogenous glucocorticoids will suppress ACTH secretion, which can lead to adrenal gland atrophy.
|
|
Cox 1 stimulates what?
|
renal flow
GI flow hemostasis GI mucus production |
|
Cox 2 stimulations?
|
inflammation
pain, fever, vascular problems increased deleterious enzymes that cause cartilage breakdown and laminar degeneration cancer |
|
Prostaglandin receptor signaling causes:
|
physiologic response
disease response |
|
COX 2 has a dual role:
|
regulates inflammatory response
increased by inflammatory stimuli (synoviocytes) |
|
What induces Cox 1?
|
induced in monocytes
|
|
What is COX 1 really imp for?
|
in the initial stages of inflammation - first 30 minutes, may be imp in positive physiologic response
|
|
What is the best way to fight inflammation?
|
COX 2 inbibitors
|
|
At a higher dose can cox 2 inhibitors inhibit cox 1 also?
|
YES. SO, we dont want to lose cox1 and also a higher cox 2 dose can decrease selectivity for cox 2.
|
|
How powerful are COX 2 inhibitors?
|
Most Cox 2 inhibitors show equal or lower efficacy to non-selective NSAIDS. BUT THEY ARE SAFER!!!
|
|
non selective cox inhibitors
|
Phenobutazone
ketoprofen banamine asprin |
|
Bute in dogs?
|
Sodium and water retention
Decreased renal blood flow Anorexia Reduced plasma proteins Leukopenia Anemia Increased BUN |
|
Banamine in small animals ADR?
|
In dogs, GI distress is the most likely adverse reaction. Symptoms may include, vomiting, diarrhea, and ulceration with very high doses or chronic use.
|
|
What will reduce ulcers from NSAIDS in dogs?
|
Misoprostol is the only drug shown to help prevent NSAID (but not corticosteroid) induced ulcers in dogs
|
|
tepoxalin?
|
a COX-1-selective inhibitor and COX-2, and the inhibition of lipoxygenase lasts approximately five hours.
|
|
Metacamms selectivity?
|
Its COX-2 selectivity is considered weak to moderate
|
|
) is the most recently approved veterinary NSAID?
|
Firocoxib (Previcox) is the most recently approved veterinary NSAID. It is a coxib-class drug with highly selective COX-2 inhibition. It has efficacy comparable to etodolac in small animal
Previcox RX |
|
Equiiox?

Good side effect with Equiiox comapred to other NSAIDS?
|
Less gastric ulceration
|
|
Side effects of Kenalog?
|
laminitis! Not used as often as it suppresses the adrenal gland for an extended period of time- may cause laminitis.
