Inflammatory response
necessary for the body's survival when faced with stressors from the environment
What triggers inflammatory response
infectious agents, ischemia, antigen-antibody interactions, burns, other injury.
Three phases of inflammatory response
1) acute, brief, local vasodilation and increased cap permeability
2) a delayed, subacute infiltration of leukocytes and phagocytic cells into the tissue
3) chronic proliferative tissue degeneration and fibrosis
Symptoms of inflammatory response
erythema (redness or irritation), edema, tenderness, and pain
Prostaglandins
cause erythema and an increase in local blood flow and remove the vasoconstrictor effects of norepinephrine. NOT GOOD
How is prostaglandins produced
they are produced by Cyclooxygenase (enzyme that changes arachidonic acid into prostaglandins).
Cyclooxygenase
COX 1 & COX 2
harmful if not controlled.

Most antiimflammatory drugs block the actions of COX 1 & COX 2
COX 2 Inhibitors
developed to reduce the inflammatory response in some tissue without destroying the tissue of the GI tract.
But might cause heart attack and stroke if prolong use.
Asprin
-Acetylsalicylic acid (ASA)
-1st line of therapy for arthritis (rheumatoid, osteoarthritis, DJD)
-Stops the production of prostaglandins
-blocks Cyclooxygenase (which produces prostaglandins)
-platelet anti aggregative
-
Salicylates
analgesics, antipyretic, antiinflammatory
Adverse reactions to antiinflammatory analgesics
tinnitus, visual distubances, edema, urticaria (hives), rashes, anorecia, epigastric discomfort, and nausea. GI bleeds.
-estimated that person on ASA loses 10 ml o blood every day from minor GI irritation
Over dosage of antiinflammatory analgesics
hyperventilation, diaphoresis, thirst, headache, drowsiness, stupor, convulsions and coma, tachycardia, and respiratory insufficiency
Salicylates: antiinflammatory analgesics
Drug interactions
-alcohol increases chance of GI bleed
-increses effect of anticoagulants, sulfonylureas, sulfonamides
-asorbic acid increases the effect of salicylates
-interact with NSAIDs increase effects, side effects, and toxicities
-increase phenytoin
-can affect lab test results
antiinflammatory analgesics
-should not be used in pts with hepatic disease
-use with caution in pts with symptoms suggesting TIAs
-should not be used in during pregnancy
-children under 12, not recommended
Reye syndrome
acute, life-threatening problem that produces vomiting and lethargy that may go on to delirium and coma with permanent brain damage and possible death.
Reye syndrome
use of aspirin after influenza, chicken pox or other viral conditions in children seems to be closely related to the development of Reye Syndrome and should be avoided.

-take with milk or meals
-if a sode is missed, it should be taken as soon as possible. if to close to next dose, just take next dose
-pt should not take aspirin or any other antiinflammatory drug while using nsaid's.
Skeletal Muscle relaxants
limit the transmission or movement of impulses in the motor pathways at the level of the spinal cord and brainstem, or they interfere with the mechanism that shortens skeletal muscle fibers so they contract
Skeletal muscle relaxants: Action

Most common side effects: drowsiness, diplopia, dizziness, weakness, mild muscular incoordination, anorexia, nausea, vomiting, syncope and hypotension
Rheumatoid arthritis
-systemic disease that involves the autoimmune response caused by failure of the body to recognize its own tissue, this results in the destruction of joints
-permanent changes that produce deformities and immobility
Osteoarthritis
localized form of joint destruction, particularly in weight bearing joints or stressed joints, that progresses gradually over time from overuse and increasing age
S/S of Arthritis
-swelling
-pain
-stiffness
Antiarthritis Medications:
salicylates and NSAID's are fist line drugs for the treatment of arthritis
but when they dont work, antiarthritis meds are used when it is confirmed it is rheumatoid arthritis.
Slow-acting Antiarthritis drugs (SAARD's)
are useful in treating significant cases of rheumatoid arthritis include:
-hydroxychloroquine sulfate
-penicillamine
-methotrexate
-gold compounds

meds are designed to reduce pain, swelling, and inflammation
(SAARD's): Gold compounds, AKA (chrysotherapy)
thought that if may inhibit lysosomal enzyme activity in macrophages and decrease their phagocytic activity. it is possible that gold affects antigen formation in the autoimmune response of pts with RA. it apperar to stop the synovitis (inflammation of the joint synovium) of active RA disease and therefore reduces the amount of damage done
(SAARD's): Gold compounds, AKA (chrysotherapy)
-many contraindications
-only 30% to 35% of pts benefit from use
-puritis around eyes, palms, and dorsa of the hands
-stomatitis (inflammation of the mouth)
-painful ulcers of the buccal mucosa, tongue, palate or pharynx
-metallic taste
(SAARD's): Gold compounds, AKA (chrysotherapy)
Three phases for dosage regimen:
1). a 2- or 3- week period of injections that increase gradually to test for severe reactions or unusual problems
2). a "loading period"of weekly injections, until a total dose of 1 g of injected gold is reached
3). a gradual decrease in dose until a maintenance dosage is found

Painful injections and should be given in gluteus maximus muscle
(SAARD's): hydroxychloroquine sulfate
used in confirmed cases of RA and systemic or discoid lupus erythematosus
SAARD's: Hydroxychloroquine sulfate
-requires 4 to 12 wks of therapy before improvement is seen. if there is no improvement after 6 months, the drug should be stopped
-corticosteroids and NSAID's may be used until the effects of the SAARD's work
SAARD's: Hydroxychloroquine sulfate
-Retinopathy is a serious adverse effect
-not to be used with other SAARD's
SAARD's: Infliximab
used in combination with methotrexate to reduce the s/s of RA and limit the worsening of damage to joints. this leads to improved physical function in pts with moderate to severe active RA who have had an inadequate response to methotrexate alone.

used in Crohn's disease (inflammatory bowel disease)
SAARD's: Infliximab
-FDA requires a label that this med may activate TB, invasive fungal infections, and other oppotunistic infections

SAARD's: Pencillamine
-requires excellent pt compliance because it is an oral preparation that pt must administer themselves
-when maintenance dosage is reached, urine and blood follow up should continue every 2 wks for 6 months
-if worsening of disease occurs during treatment, NSAID's are indicated rather than increase of the dosage of Pencillamine
-no therapeutic effect may be seen for 3 to 6 months
SAARD's: Pencillamine - Adverse Reaction

-crystals are sharp, long, and jagged edges that tear tissue they come in contact with
Gout
-a form of arthritis caused when the body makes to much or does not get rid of uric acid
-S/S = swelling, heat, inflammation and severe pain
Uricosuric agents
-increase the excretion of urate salts in the urine by blocking tubular reabsorption of these salts in the kidney
Uricosuric agents
-do not have significant antiinflmmatory or analgesic properties and therefore are of little help during an acute episode of gout
AntiGout: Colchicine

-increased sensibility to CNS depressants
Anti Gout: Pt Teaching
-at least 50% of initial attacks occur int the great toe
-usually develops in the lower extremities
-URICOSURIC agents are to be started only after the acute attack has resolved
-initiation of therapy with uricosuric agents may cause an acute attack of gout
Anti Gout
-colchicine are not to be given IM or subcutaneously but must be given IV
-with acute attack, colchicine should be given immediately, and then a dose should be given every hour until either symptoms go away or the pt develops signs of toxicity
Anti Gout: Uricosuric drugs
-do not have an effect on acute gouty attacks, but they help prevent attacks if they are taken regularly
-Take with meals to prevent GI issues
