Anti-Inflammatory and Pain-Reducers Flashcards
Natural response of living tissue to injury and infection
Inflammation
Induce pain and swelling
Kinins
Produce heat, fever, and pain
Prostaglandins
Produce redness and swelling
Histamine
2 Main groups of anti-inflammatory agents
Sterioids and NSAIDS
2 Types of steroidal anti-inflammatories
- Coricosteroids
2. Mineralocorticoids
Glucocorticoids inhibit the production of this enzyme
phospholipase
AKA steroids
Synthetically produced in a lab
Short-acting, intermediate acting, or long acting
Provide analgesia, anti-inflammatory, reduce scarring and tissue damage, and relieve pruritis
Glucocorticoids
5 drawbacks to using Glucocorticoids
- Delay wound healing
- Increase risk of infection
- GI ulcers and bleeding
- Increase risk of corneal ulceration
- Increase blood glucose levels
A short action steroid lasts for
<12 hrs
An intermediate acting steroid lasts for
12-36 hrs
A long-acting steroid lasts for
> 48hrs
Glucocorticoids can be combined with
antifungals and antibiotics
3 most common S/E of steroid use
- Polyuria
- Polydipsia
- polyphagia
If an animal is on a steroid for too long, they can develop
iatrogenic Cushing’s dz
Hyperadrenocorticism is AKA
Cushing’s Dz
If the steroid dose is not tapered down, the patient could develop
iatrogenic Addison’s Dz
Hypoadrenocorticism is AKA
Addison’s Dz
C/S of this dz include: PU/PD, pendulous belly, lethargy, bilateral symmetrical alopecia
Cushing’s Dz (hyperadrenocorticism)
C/S of this dz include: weakness, lethargy, V+/D+
Addison’s Dz (hypoadrenocorticism)
What type of pts should you avoid giving glucocorticoids to because it could induce hyperglycemia?
Diabetic
These are blood thinning agents that have less S/E than steroids?
NSAIDs
2 forms of cyclooxygenase
COX 1 - stomach
COX 2 - inflammation
NSAIDs are AKA
prostaglandin inhibitors
How should you treat a cat with Aspirin?
Baby aspirin q 72 hr
Baby aspirin
81 mg/tab
Adult aspirin
325 mg/tab
Buffered aspirin neutralizes
stomach acid
This type of aspirin is dissolved by the intestines
enteric-coated
This type of aspirin is found with steroids or other NSAIDs
Combination
NSAID used in equine medicine that is highly protein-bound
Used for analgesia, anti-pyretic, anti-inflammatory
Phenylbutazone
AKA bute
This type of NSAID is NOT RECOMMENDED for animals because it is easily toxic
Proprionic acid derivative
Ibuprofen
A proprionic acid derivative used in birds, cats, and dogs
Ketoprofen
A proprionic acid derivative used in horses but not recommended for dogs
Naproxen
A proprionic acid derivative AND COX-2 inhibitor used in dogs and extra-label for food producing animals
Carprofen (Rimadyl)
A COX-2 inhibitor used for post-op pain management
Absorbs better with food
Deracoxib
A COX-2 inhibitor used for post-op pain that produces soft stool as a S/E
Cats can only receive this drug once in their life orally
Meloxicam
A COX-2 inhibitor AKA Equioxx used to control osteoarthritis in dogs and horses
Firocoxib
This drug is FDA approved for cattle (beef and dairy) and horses and extra-label for other species
Used for musculoskeletal pain, colic, shock IVDD, post op surgery pain
Flunixin Meglumine
AKA Banamine
A good substitute for Carprofen
Etodolac
Similar to aspirin used for osteoarthritis in equine medicine
Slow 2-3 day onset
Comes as a granular form mixed in with feed
Meclofenamic acid
AKA Arquel
This drug blocks COX 1 and COX 2 so it results with less GI upset and ulcers
Tablet QUICKLY dissolves in animal’s mouth
Tepoxalin
AKA Zubrin
This drug inactivates super radicals produced by inflammation
Has a garlic odor/taste, penetrates tissues well
DMSO
Dimethyl Sulfoxide
These are naturally made by the body and are the most costly
Polysaccharides in proteoglycans
GAGs
GAG used to increase motility and flexibility
Normally part of synovial fluid in animals
Cushions the joint as an intra-articular inj in horses and dogs
Hyaluronate sodium
AKA Hyalovet
Semi-synthetic mix of glycosaminoglycans from bovine cartilage
PGAGs
AKA Adequan
Considered neutraceuticals if combined
Restores cartilage
Glucosamine and Chondroitin sulfate
These type of drugs are used for itching, motion sickness, and anaphylactic shock
Anti-histamines
What do H1s do?
Produce symptoms and activate allergic reactions
What do H2s do?
Activate the acid-producing parietal cells of the stomach lining
Main Side effect of Antihistamines
drowsiness
These drugs adjust the immune response to a desired level
Immunomodulators
Immunomodulators that increase the immune response
Immunopotentiation
Immunomodulators that decrease the immune response
Immunosuppression
do not affect the immune system and cause no response
Immunologic tolerance
This drug suppresses immune system responses through T-Cell activity
Most effective immunosuppressant
Used for dermatitis in dogs
STEP DOWN DOSING
Cyclosporine
If an animal is experiencing mild or moderate pain, they should be treated with
NSAIDs
If an animal is experiencing severe, traumatic pain, they should be treated with
a narcotic
An analgesic NEVER used in vet medicine
Works by blocking nociceptors, not inflammation
Tylenol
Acetaminophen
Toxicity antidote for acetaminophen
acetylcysteine
