Exam 4 Meds Flashcards
Prednisone
Corticosteroids/Glucocorticoids
For
* Short-term treatment of many inflammatory disorders. To relieve discomfort. To give the body a chance to heal from the effects of inflammation. In illnesses like cancer, ulcerative colitis, asthma, anaphylaxis/allergies.
MOA

AE
* Related to route of administration. Systemic use is associated with endocrine disorders. HA, HTN, agitation, weight gain, can induce DM, Na/H20 retention, immunosuppression, impaired wound healing
CI: Known allergy, Acute infection, Lactation
Caution: Diabetes, Acute peptic ulcer, infection
Drug
* Increase in drug when given with erythromycin, ketoconazole, or troleandomycin. Decrease in drug when given with salicylates, barbiturates, phenytoin, or rifampin.
Cortisone
Mineralocorticoid
For
* Replacement therapy in primary and secondary adrenal
insufficiency
MOA
* Holds sodium, and with it, water in the body. Causes the excretion of potassium & hydrogen by acting on the renal tubule
AE
* Increase fluid volumes. Allergic reactions. Headaches, arthralgias. Heart failure
CI: Known allergy. HTN. CHF. Cardiac disease
Caution: Pregnancy. Presence of any infection. High sodium intake
Drug
* Decrease effectiveness with salicylates, barbiturates, hydantoins, rifampin, and anticholinesterases
7 S’s of Steroid Precautions
- Swollen: water gain = weight gain, report 1lb in 1 day or 2-3lbs in a few days
- Sepsis: low WBC, fever is priority
- Sugar: increases, hyperglycemia
- Skinny: muscles and bones - osteoporosis
- Sight: cataract risk - refer to optometrist
- Slowly taper off: prevent adisonian crisis
- Stress and surgery: increase the dose
Levothyroxine
Thyroid Replacement Hormones
For
* Replacement therapy in hypothyroidism; pituitary TSH suppression in the treatment of euthyroid goiters, management of thyroid cancer; thyrotoxicosis in conjunction with other therapy; myxedema coma
* “Leaves T3 and T4 in the body”
* L = life long drug; long, slow onset (3-4 wks)
* E = early morning on empty stomach (30-60 min before eating)
* V = very hyper, high HR/BP/temp, report agitation and confusion
MOA
* Increases the metabolic rate of body tissues, increasing oxygen consumption, respiration, and heart rate; the rate of fat, protein, and carbohydrate metabolism; and growth and maturation
AE
* Skin reactions, Symptoms of hyperthyroidism, Cardiac stimulation, CNS effects, Nervousness, palpitations, NVD, HA, tachycardia, loss of hair (children)
* Assess for MI, Addison’s disease, VS, hormone levels, Thyrotoxicosis, thyroid storm
CI: Known allergy, Thyrotoxicosis, Acute MI
Caution: Lactation, Hypoadrenal conditions such as Addison’s
* preg safe!
Drug
* Cholestyramine, Oral anticoagulants, Digitalis, Theophylline
Propylthiouracil / Sodium Iodine
Antithyroid Agents
For
* hyperthyroidism
* PTU = puts the thyroid underground
MOA
* Thioamides: prevent formation of thyroid hormone within the thyroid cells, lowering the serum level, partially inhibit conversion of T4 to T3
* Iodine Solutions: high doses block thyroid function
AE
* Thioamides: Thyroid suppression
* Iodine Solutions: Hypothyroidism - resp failure
CI: Known allergy, pregnancy
Caution: Lactation
Drug
* Thioamides: Oral anticoagulants, theophylline, metoptolol, propranolol, digitalis
* Iodine Solutions: Anticoagulants, theophylline, digoxin, metoprolol, propranolol
Alendronate (Fosamax) / ibandronate (Boniva)
Bisphosphonates
For
* Osteoporosis, Padget’s disease, Steroid induced osteoporosis
MOA
* Slow or block bone resorption; by doing this, they help to lower serum calcium levels, but they do not inhibit normal bone formation and mineralization
AE
* headache, NVD; bone pain with Paget’s disease
CI: Bisphosphonates- Hypocalcemia, pregnancy and lactation, renal dysfunction, GI disease
Drug
* antacids, calcium products, iron, or multiple vitamins and aspirin
Insulin
For
* Treatment of type 1 diabetes mellitus
* Treatment of type 2 diabetes mellitus in patients whose diabetes cannot be controlled by diet or other agents
MOA
* Hormone that promotes the storage of the body’s fuels, Facilitates the transport of various metabolites and ions across cell membranes, Simulates the synthesis of glycogen from glucose, Reacts with specific receptor sites on the cells.
AE
* hypoglycemia, ketoacidosis
Caution: Pregnancy and lactation
Drug
* When given with any drug that decreases glucose levels; Beta blockers
Glyburide
Sulfonylureas
For
* T1DM
* T2DM where diabetes cannot be controlled by diet and other agents
* Adjunct to diet and exercise to lower blood glucose in T2
MOA
* Bind to potassium channels on pancreatic beta cells, may improve insulin binding to insulin receptors and increase number of insulin recep tors
* Stimulate insulin release from beta cells in the pancreas; they improve binding to insulin receptors
AE
* NVD , skin reactions, hypoglycemia
CI: T1, diabetic complications, allergy
Caution: preg and lactation
Drug
* do not intereact with as many protein bound drugs
* drugs that acidifies the urine, Beta Blockers, alcohol
Glucagon
Glucose Elevating Agent
For
* Treatment of hypoglycemia
* Raise the blood level of glucose when severe hypoglycemia occurs (<40 mg/dL)
MOA
* Increase the blood glucose levels by decreasing insulin release and accelerating the breakdown of glycogen in the liver to release glucose
AE
* GI upset; Vascular effects
CI: Known allergy; Pregnancy and lactation
Caution: Hepatic dysfunction or cardiovascular disease
Drug
* Thiazide diuretics; Anticoagulants
