good for patients who take daily aspirin as it is coated and will protect their GI
46
Aspirin for Acute MI Administration Notes
Shown to reduce cardiac death after myocardial infarction (MI) Should be administered at the first sign of MI If not given before arriving in the emergency department, aspirin is one of the first drugs given if there are no contraindications. ~~chew it~~
47
Aspirin Dosage Notes
for daily aspirin it is best to go with the lower dose of 81 mg over the 325 mg, however it is not unheard of
48
Reye’s Syndrome
Acute and potentially life-threatening condition involving progressive neurologic deficits that can lead to coma and may also involve liver damage. Triggered by viral illnesses such as influenza as well as by salicylate therapy itself in the presence of a viral illness. Survivors of this condition may or may not have permanent neurologic damage.
49

55
Celecoxib (Celebrex) Adverse Reactions
Adverse effects include headache, sinus irritation, diarrhea, fatigue, dizziness, lower extremity edema, and hypertension Theoretically less rick for GI upset than NSAIDs but the risk is still there ** not for patients with known sulfa allergy**

58
Naproxen
Second most commonly used NSAID Somewhat better adverse effect profile than ibuprofen Fewer drug interactions with ACE inhibitors given for hypertension
59
COX Enzymes
**COX-1: has a role in maintaining the gastrointestinal (GI) mucosa** COX-2: going to have the beneficial effects on inflammation with little effects on GI
60
Aspirin
Irreversible inhibitor of COX-1 receptors within the platelets themselves Reduced formation of thromboxane A2, a substance that normally promotes platelet aggregation other NSAIDs lack these antiplatelet effects
61
NSAID contraindications
**aspirin allergy must not receive any other NSAIDs** (because of bleeding risk:) Vitamin K deficiency Peptic ulcer disease Renal disease. NSAIDs can cause renal problems and damage
62
NSAID Adverse Effects
GI: heartburn to severe GI bleeding **Acute renal failure** Noncardiogenic pulmonary edema Increased risk of MI and stroke – not aspirin though Altered hemostasis Hepatotoxicity Skin eruption, sensitivity reaction Tinnitus, hearing loss
63
Misoprostol (Cytotec)
prevents GI bleed Synthetic prostaglandin E1 analogue: inhibits gastric acid secretion and has a cytoprotective component Mechanism of action: unclear Prophylactic use - not a treatment. IN OB: to ripen the cervix
64
NSAIDs and Renal Function
Use of NSAIDs can compromise existing renal function. Renal toxicity can occur in patients with dehydration, heart failure, liver dysfunction, or use of diuretics or angiotensin-converting enzyme (ACE) inhibitors.
65
NSAID Black Box Warning
All NSAIDs (except aspirin) share a black box warning regarding an increased risk of adverse cardiovascular thrombotic events, including fatal MI and stroke. NSAIDs may counteract the cardioprotective effects of aspirin.
66
NSAID GI Adverse Effects
Dyspepsia, heartburn, epigastric distress, nausea GI bleeding* (tell pt to stop drinking) Mucosal lesions* (erosions or ulcerations) *Misoprostol (Cytotec) can be used to reduce these dangerous effects.
67
NSAID Renal and Cardiovascular Adverse Effects
Renal -Reductions in creatinine clearance -Acute tubular necrosis with renal failure Cardiovascular -Noncardiogenic pulmonary edema
68
NSAID Interactions
Anticoagulants – can increase bleeding Aspirin – increased risk of GI problems Corticosteroids and other ulcerogenic drugs – increased ulcerogenic effects Protein bound drugs – effects absorption Diuretics and ACE inhibitors – decrease hypotensive effects and decrease diuretic effects
69
Salicylates Administration Notes
**NOT FOR CHILDREN** - Reyes Syndrome take with food or milk to prevent GI upset Therapeutic effect may take 3-4 weeks
70
Glucosamine and Chondroitin
Herbal Products used to treat the pain of OA Adverse effects -GI discomfort -Drowsiness, headache, skin reactions (glucosamine) Drug interactions -Enhances effects of warfarin -May increase insulin resistance (glucosamine)
71
Gout
condition that results from inappropriate uric acid metabolism (make too much or cant get rid of it) Uric acid crystals are deposited in tissues and joints, resulting in pain Hyperuricemia (elevated uric acid levels, a blood test, not a urine test) - often in feet, you will see BIG toes -
72
Antigout Drugs
first line therapy is NSAIDs, these are secondary allopurinol (Zyloprim) febuxostat (Uloric) colchicine (Colcyrs) probenecid (Benemid) sulfinpyrazone (Anturane)
73
Allopurinol (Zyloprim)
Used to prevent uric acid production and to prevent acute tumor lysis syndrome Exfoliative dermatitis, Stevens-Johnson syndrome, and toxic epidermal necrolysis **monitor uric acid levels**
74
Probenecid (Benemid)
Inhibits the reabsorption of uric acid in the kidneys and thus increases the excretion of uric acid: less uric acid in the blood, more in the urine
75
Febuxostat (Uloric)
Nonpurine selective inhibitor of xanthine oxidase More selective for xanthine oxidase than allopurinol May pose a greater risk of cardiovascular events than allopurinol
76
Colchicine
Reduces inflammatory response to the deposits of urate crystals in joint tissue Used for short-term management or prevention of gout May cause short-term leukopenia and bleeding into the GI or urinary tracts Have the patient report any blood in urine Empty stomach Increase fluid intake – important to stay hydrated joint pain should decrease
77
to prevent organ transplant rejection
mycophenolate mofetil (CellCept) daclizumab (Zenapax)* -BBW: lymphoproliferative (can initiate that word and hypersensitivity reactions) basiliximab (Simulect)* sirolimus (Rapamune) *give prednisone to prevent anaphylactic response
78
Belatacept (nulojix)
only drug for long term IV maintenance
79
Why pre medicate with corticosteroids before immunosuppressants
Cytokine release syndrome can lead to anaphylaxis. Patients are often pre-medicated with corticosteroids to avoid or alleviate that problem. solumedrol often used
80
azathioprine (Imuran)
Used as an adjunct medication to prevent rejection of kidney transplants Also used in the treatment of rheumatoid arthritis Expected reactions include leukopenia, thrombocytopenia, hepatotoxicity. monitor CBC – can induce leukopenia. Also liver function tests.
81
cyclosporine (Cyclosporin A)
Primary drug used in the prevention of kidney, liver, heart, and bone marrow transplant rejection; other autoimmune disorders (refractory RA, plaque psoriasis)
82
cyclosporine (cyclosporin A) administration notes
Oral tabs: when possible to avoid skin penetration;* same time QD Oral liquids; mix with juice, choc milk, etc. No Styrofoam cups IV: no bolus dosing; use a pump; reactions in first 30 minutes; serum levels monitored
83
cyclosporine (cyclosporin A) does not intermingle with
Often combined with a corticosteroid; oral antifungal Co administration of allopurinol ↑ action of cyclosporine, but also toxicity! * Grapefruit juice will ↑serum levels, ↑ toxicities
84
Cyclosporine Adverse Reactions
CV: moderate hypertension in 50% of cases!* CNS: neurotoxicity/tremors 20% of patients Liver: hepatotoxicity with cholestasis, ↑bilirubin Renal: toxic and often dose limiting – BBW Other: hypersensitivity, gingival hyperplasia, hirsutism
85
Tacrolimus (Prograf)
Prevention of liver, kidney, heart transplant rejection IV and PO formula’s available; IV 1st 2-3 days post transplant Switch to PO and maintain may also be used for severe psoriasis, Crohn’s, nephritis, atopic dermatitis
86
Tacrolimus (Prograf) Adverse Reactions
Side effects: predominately renal (albuminuria, dysuria, ARF & CNS (agitation dconfusion, neuropathy)
87
Tacrolimus (prograf) does not intermingle with
cyclosporine
88
glatiramer acetate (Copaxome)
The only immunosuppressant drug used for the treatment of multiple sclerosis (MS) Used to reduce the frequency of MS relapses (exacerbations) in relapsing-remitting multiple sclerosis (RRMS)
89
Nursing Implications for Immunosuppressants
watch for signs of infection **WATCH FOR MILD SYMPTOMS** Renal, liver, and cardiovascular function studies, CBC Take with food Oral given to avoid IV/IM related infections
90
oral cyclosporine administration notes
must be mixed in a glass container, Styrofoam fucks it up
