Terms in this set (73)
Norepinephrine-Adrenergic (adrenergic comes from the word adrenalin)
Alpha 1-all sympathetic target organs except the heart-constrict the blood vessels and dilation of pupils
Alpha 2-Presynaptic adrenergic nerve terminal-inhibits the release of norepinephrine
Beta 1-Heart and Kidneys (BETA 1-ONE HEART)-increased heart rate and force of contraction, release of renin

EXAM 1 DRUGS!!!!
Metoprolol/Lopressor ENDING OLOL
Beta Blockers are use with heart failure, hypertension, angina and with myocardial infarctions.
Action = Blocks Beta-Receptors in the heart causing...
Decreases = HR, force of contraction, Rate of atrioventricular (AV) conduction
SE = Bradycardia, lethargy, GI disturbance, congestive heart failure, decrease BP, depression
The beta blockers stop sympathetic nervous system stimulation of the heart. Does not allow the heart rate and blood pressure to rise with stress thus lowering the oxygen demand of the heart. It is very heart protective!
Will slow the heart rate and lower the blood pressure
Can have beta 2 blockage with larger doses-will constrict the bronchioles-watch for clients with known COPD, Asthma
Check pulse-needs to be 60 or above
Check blood pressure-if hypotensive do not give (Systolic below 100 is a good rule of thumb I go by)
Monitor for sexual dysfunction-impotence for men-a good reason for non-compliance
Drowsiness/Fatigue-operating heavy machinery, driving could put client at risk
Contraindicated with Heart Blocks, Bradycardia, Worsening Heart Failure
Increases Hypoglycemic effect of Insulin-monitor blood sugars and for hypoglycemia, may need to lower insulin dosage
Beta Blockers have to be weaned slowly to prevent rebound hypertension and tachycardia-if a client wants to stop his beta-blocker they need to contract their physician
CCB,/calcium channel blockers
Nifedipine/Adalat/Procardia/Norvasc-controls blood vessels
Verapamil/Calan/Isoptin/Verelan-controls heart rate and blood vessels
Angina/Raynaud's/Vasospastic Angina/Atrial Arrhythmia's
Blocks calcium channels in the myocardial and vascular smooth muscles, decreases the contraction of smooth muscle-relaxes the arteries-vasodilation. Blocking of calcium channels in the SA and AV node-Slows conduction through the SA and AV node. Decreases the force of contraction slows heart rate
Grapefruit juice may increase absorption of nifedipine
Side Effects: Relaxes smooth muscle and cardiac muscle-
Dizziness-Take lying, sitting and standing B/P, educate client to sit and stand slowly
Peripheral edema-assess for edema, monitor for worsening (diuretic)
Reflex tachycardia-monitor for elevated heart rate (may need a BB)
Constipation-increase fibers and fluids (if not restricted) stool softener
Fatigue-Due to low heart rate-monitor EKG, pulse rate and rhythm
Weakness-Monitor B/P and Heart Rate
Impotence and sexual dysfunction-Discuss possibility with client-have client to call and not just to stop medications
Hepatotoxicity-ALT, AST, ALK PHOS, Bilirubin
MI-Monitor for chest pain, dyspnea, increases fatigue, weakness

Prevents Angiotensin 1 from converting to Angiotensin 2 in the lungs-leaves the Angiotensin 1 hanging in the lungs-creates irritation-cough
Vasodilation-mostly arteriole (decreases afterload)
Excretion of sodium and water-retention of K (decreases preload)
Treats hypertension and heart failure
Do not take 2nd and 3rd Trimester of pregnancy
SE = Angioedema-allergic reaction-swelling of tongue, throat-stop taking and notify md
Hyperkalemia-monitor for widening and slowing of pulse/qrs, weakness, fatigue, avoid high K foods, AVOID SALT SUBSTITUTES-usually very high in K, avoid potassium sparing diuretics, sport drinks are high in K also

Arb's-Angiotensin receptor blockers, sartan's
No Cough, same effects and side effects as Ace's-just not as potent
Nitroglycerin/Nitrostat, Nitro-Bid, Nitro-Dur
Nitrates form nitric acid which is a relaxes smooth muscle and dilates venous and arterial blood vessels
Open veins-blood pools in the legs-not as much blood returning to the heart-reduces preload
Open arteries-heart does not have to work as hard to pump blood out of the heart-reduces afterload
Opens the coronary arteries and helps supply blood to the heart tissue
Can be given sublingually, orally, topically, IV, buccal
Can be for acute or long term use
Nitroglycerin dilates any artery and vein-including yours if you touch it while administering it-WEAR GLOVES
Nitroglycerin IV needs a glass bottle and covered from light-some hospitals still use special tubing (nitro is absorbed in the tubing)
Short term-nitrostat-sublingually-1 tablet every 5 minutes x 3 for relief of chest pain-still having chest pain call 911/physician
Long-term nitro-dur will last for up to 14 hours in the body
Headache-dilates the cerebral arteries-do not give with head trauma or increased intracranial pressure
Hypotension and reflex tachycardia-do not give with hypotension, monitor blood pressure and HR when administering
Hypotension-correct hypervolemia prior to giving nitroglycerin
DO NOT GIVE WITH VIAGRA, LEVITRA, OR CIALIS (nitroglycerin and Viagra increase nitric acid and relaxation of the smooth muscles-can kill a client with hypotension with a combination of these drugs)
Digoxin/Digitek, Lanoxin, Lanoxicaps (Dig)
Increases the contractility of the heart muscle - Inotropic effect-
Increases cardiac output
Also Suppresses the SA node and slows conduction through the AV node

up to 20 hours
Treats hypothyroidism. Also treats an enlarged thyroid gland (goiter) and thyroid cancer.
Naturally occurring glucocorticoids (hydrocortisone and cortisone), which also have salt-retaining properties, are used as replacement therapy in adrenocortical deficiency states. Their synthetic analogs are primarily used for their potent anti-inflammatory effects in disorders of many organ systems. Glucocorticoids cause profound and varied metabolic effects. In addition, they modify the body's immune responses to diverse stimuli.
Hydrocortisone belongs to the family of medications known as corticosteroids. It is used to treat many different conditions. It works by reducing swelling, inflammation, and irritation or as a replacement when the body does not make enough cortisol. Hydrocortisone is more commonly used to treat allergic reactions, some skin conditions, severe asthma, lupus, and arthritis.
It can also be used to treat steroid deficiency in the body, certain blood disorders, certain types of cancer, multiple sclerosis, and ulcerative colitis.
When people are under stress, levels of cortisol hormone rise. Chronic stress can result in chronically high levels of cortisol, which can lead to symptoms like weight gain, memory problems, high blood pressure, and other health problems. The stress release of cortisol is designed to enable the flight or fight response with a quick burst of energy, but when people are in a state of constant high stress, levels of the hormone never have a chance to fall back down to normal levels. This is one reason why treatments for chronic stress include exercises and activities that are designed to reduce stress levels, allowing production of this hormone to slow down.
Treats hyperthyroidism (too much thyroid hormone produced by the thyroid gland).
Treats Graves' disease and hyperthyroidism (too much thyroid hormone from the thyroid gland) in patients who have already been treated with other medicines (such as methimazole) that did not work well.
H2 Blockers (-tidine)
This medication is used to treat the symptoms of too much stomach acid such as stomach upset, heartburn, and acid indigestion. Aluminum and magnesium antacids work quickly to lower the acid in the stomach. Liquid antacids usually work faster/better than tablets or capsules.
This medication works only on existing acid in the stomach. It does not prevent acid production. It may be used alone or with other medications that lower acid production (e.g., H2 blockers such as cimetidine/ranitidine and proton pump inhibitors such as omeprazole).
This medication can cause nausea, constipation, diarrhea, or headache
by mouth, usually after meals and at bedtimehis product may react with other medications (e.g., digoxin, iron, tetracycline antibiotics, quinolone antibiotics such as ciprofloxacin), preventing them from being fully absorbed by your body.
Do not give
to patients with:
Monitor elevated serum glucose
(dec blood sugar)
Is a polypeptide hormone that controls the storage and metabolism of carbohydrates, proteins, and fats. This activity occurs primarily in the liver, in muscle, ind in adipose tissues after binding of the insulin molecules to receptor sites on cellular plasma membranes
Logs -->fast acting
is a man-made insulin used to control high blood sugar in adults/children with DM.
Reg -->short acting
Humulin® R U-100 is a polypeptide hormone structurally identical to human insulin synthesized through rDNA technology in a special non-disease-producing laboratory strain of Escherichia coli bacteria
Often used in combination with a shorter-acting insulin. NPH insulin is a man-made insulin product is the same as human insulin. It replaces the insulin that your body would normally make. It is an insulin (isophane). It starts to work more slowly but lasts longer than regular insulin. Helps blood sugar (glucose) get into cells so your body can use it for energy.
Lantas -->long-acting insulin
Treats diabetes mellitus. Insulin is a hormone that helps get sugar from the blood to the muscles, where it is used for energy. This type of insulin usually works longer than regular insulin.
Used with diet and exercise to control blood sugar in patients with type 2 diabetes. May be used alone or with other medicines.
starting dose of GLUCOPHAGE (metformin hydrochloride) Tablets is 500 mg twice a day or 850 mg once a day, given with meals. Dosage increases should be made in increments of 500 mg weekly or 850 mg every 2 weeks, up to a total of 2000 mg per day.
The purpose of both insulin and metformin is to lower blood glucose levels. Insulin injections replace the insulin your body can no longer make when the cells in the pancreas cease to function. Metformin is an oral hypoglycemic, which lowers blood glucose levels by decreasing the liver's output of glucose. Metformin also increases insulin sensitivity, and improves not only blood glucose levels but also lipid levels and often results in weight loss.
14% take insulin only
57% take oral medications only
14% take a combo of both.
Insulin VS Metformin Treatments? Mechanisms
Oral hypoglycemics are used only in Type 2 diabetes, because Type 1 diabetics make little or no insulin, so reducing the glucose levels produced by the liver won't reduce blood glucose levels. Without insulin, glucose can't enter cells and remains in the bloodstream. While all Type 1 diabetics take insulin, some Type 2 diabetics also need insulin in addition or instead of oral hypoglycemics such as metformin. Insulin, which must be injected, comes in several forms and doses, and can have rapid or slow onset.
Insulin VS Metformin Treatments?....Considerations
For Type 1 diabetics, insulin is the only medication choice. For Type 2 diabetics, medical practitioners generally start with an oral hypoglycemic such as metformin and add insulin only when oral hypoglycemics can't stabilize blood glucose levels.
Insulin VS Metformin Treatments?....Benefits
Both metformin and insulin help to normalize blood glucose levels. Keeping blood glucose levels as close to normal levels as possible limits the damage high blood glucose imposes on every blood vessel and organ of the body. High blood glucose levels lead to poor circulation, heart problems, vision problems, nerve damage, susceptibility to infection and kidney damage. While damage occurs earlier in Type 1 diabetics, Type 2 diabetics can also experience complications.
Insulin VS Metformin Treatments?....Side Effects
Diarrhea, the most common side effect of metformin, improves if metformin is taken with food. Liver failure and increased acidity, acidosis, occur rarely, The Merck Manuals Online Medical Library states. Insulin must be carefully calibrated or blood glucose levels may drop too low, a condition called hypoglycemia. Taking insulin without eating or taking too much insulin for the amount of food eaten can cause hypoglycemia. Symptoms of hypoglycemia include weakness, shakiness, sweating, lightheadedness and confusion; coma and death can result in severe cases.
