2 Ways of increasing FLUID volume?
ADH/Aldosterone are 2 ways our body maintains homeostasis influid volume.
ADH-sent by pituitary to make kidneys reabsorb H20 in thecollecting ducts Aldosterone-sensed by the kidneys-release of renin-convertsangiotensin 1 to 2-angiotensin 2 allows aldosterone to act on thekidneys to increase Na reabsorption and K depletion
4 H2 receptor antagonists -tidine
-cimetidine - inhibits many cytochrome P450 enzymes and thus can interfere w/ hepaticmetabolism; not recommended during pregnancy or nursing. also has antiadrenergic effects -->gynecomastia-ranitidine-famotidine-nizatidine*reversibly and competitively inhibit the binding of HISTAMINE to H2 receptors, resulting insuppression of gastric acid secretion*they also indirectly decrease gastrin and acetylcholine-induced gastric acid secretion-peak plasma levels achieved w/in 1-3 hours**benefits: CHEAPER, with the exception of cimetidine, safe for preg. and adverse effects betterstudied

Addison's
When glucocorticoids are in use, especially in higher dose andlong term therapy-the adrenal glands shrink/atrophyIf we taper clients off glucocorticoids, then adrenal glands return tonormal function.If we suddenly stop the glucocorticoids, we have Addison's Crisis,the client will start losing there blood pressure, have renal failure,be very tired and lethargic, have nausea and vomiting, asthenia(lack of strength), they will die without getting a dose ofglucocorticoids
Adrenal GlandsSit on top of the kidneys.Inner Medulla- Epi/NorepinephrineOuter Cortex - Glucocorticoids (sugars),Mineralocorticoids (salts),gonadocorticoids (sex)
Adverse effects of PPI's are: not common
Adverse effects of PPIs
-headache, nausea, disturbed bowel function, abdominal pain-the large increase in gastrin secretion ---> can induce ECL cellsand parietal cells to hyperplasia -->carcinoid tumors ??? (notobserved in humans)
-may affect effectiveness of clopidogrel (anti-platelet agent)because CYP2C19 metabolizes PPIs as well as activates clopidogrel:this enzyme has various polymorphisms and is responsible for thevariation in clearance rate of PPIs

Cortef
Naturally occurring glucocorticoids (hydrocortisone andcortisone), which also have salt-retaining properties, are used asreplacement therapy in adrenocortical deficiency states. Theirsynthetic analogs are primarily used for their potent anti-inflammatory effects in disorders of many organ systems.Glucocorticoids cause profound and varied metabolic effects. Inaddition, they modify the body's immune responses to diversestimuli.

Corticoidsteroids -- glucocorticoids
Anti-inflammatory drugsMust taper them off Inhibits --> Making of prostaglandins, suppress histamines, stops some functions ofphagocytes/lympocytes (so, when infection happens they're aren't enough WBC to fight offinfection)SE = suppress adrenal glands --> Addison's crisis...hyperglycemia, mood changes, cataracts,PUD, electrolyte inbalance, osteoporosis, mask infections.Long-term = Cushing's syndrome
Glucocorticoids = inhaled, oral, IVEnd in -oneWe give all 3 types for Asthma/COPD
Sickest = IV, then PO, then inhaled glucocorticoid
Corticosteroids
Corticosteroids produced in the adrenal cortex. Corticosteroids: stress response, immune response, regulation ofinflammation, carbohydrate metabolism, protein catabolism, bloodelectrolyte levels, behavior.
Glucocorticoids: Cortisol. Control carbohydrate, fat protein metabolism,anti-inflammatory by preventing phospholipid release, decreasingeosinophil action and a number of other mechanisms.Mineralocorticoids: Aldosterone. Control electrolyte/water levels, mainlyby promoting sodium retention in the kidney.
Cortisol
When people are under stress, levels of cortisol hormone rise. Chronicstress can result in chronically high levels of cortisol, which can lead tosymptoms like weight gain, memory problems, high blood pressure, andother health problems. The stress release of cortisol is designed to enablethe flight or fight response with a quick burst of energy, but whenpeople are in a state of constant high stress, levels of the hormone neverhave a chance to fall back down to normal levels. This is one reason whytreatments for chronic stress include exercises and activities that aredesigned to reduce stress levels, allowing production of this hormone toslow down.
Coumadin

Glucophage (metformin)
Used with diet and exercise to control blood sugar in patients with type 2diabetes. May be used alone or with other medicines.starting dose of GLUCOPHAGE (metformin hydrochloride) Tablets is 500 mgtwice a day or 850 mg once a day, given with meals. Dosage increases shouldbe made in increments of 500 mg weekly or 850 mg every 2 weeks, up to atotal 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 thecells 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 bloodglucose levels but also lipid levels and often results in weight loss.

Insulin
Is a polypeptide hormone that controls thestorage and metabolism of carbohydrates,proteins, and fats. This activity occursprimarily in the liver, in muscle, ind inadipose tissues after binding of the insulinmolecules to receptor sites on cellular plasmamembranes
Insulin (never given PO)
Available in 1922 (1922-1980's Insulin from Pork or Beef pancreas)Insulin must be available when glucose is in the bloodControl of Diet-when and what is eatenControl of ExerciseDuring IllnessNever PO-GI Juices destroys the insulinVial in use @ room temp (extra vial in refrigerator)
Recombinant DNA (rDNA) now is used almost exclusivelyMost effective, fewer allergies, lower incidence of resistance
Insulin VS Metformin Treatments?Mechanisms
Oral hypoglycemics are used only in Type 2 diabetes, because Type1 diabetics make little or no insulin, so reducing the glucose levelsproduced by the liver won't reduce blood glucose levels. Withoutinsulin, glucose can't enter cells and remains in the bloodstream.While all Type 1 diabetics take insulin, some Type 2 diabetics alsoneed insulin in addition or instead of oral hypoglycemics such asmetformin. Insulin, which must be injected, comes in several formsand doses, and can have rapid or slow onset.
Insulin VS MetforminTreatments?....Benefits
Both metformin and insulin help to normalize blood glucose levels.Keeping blood glucose levels as close to normal levels as possiblelimits the damage high blood glucose imposes on every bloodvessel and organ of the body. High blood glucose levels lead to poorcirculation, heart problems, vision problems, nerve damage,susceptibility to infection and kidney damage. While damageoccurs earlier in Type 1 diabetics, Type 2 diabetics can alsoexperience complications.
Insulin VS MetforminTreatments?....Considerations
For Type 1 diabetics, insulin is the onlymedication choice. For Type 2 diabetics,medical practitioners generally start with anoral hypoglycemic such as metformin andadd insulin only when oral hypoglycemicscan't stabilize blood glucose levels.
Insulin VS Metformin Treatments?....SideEffects
Diarrhea, the most common side effect of metformin, improves ifmetformin is taken with food. Liver failure and increased acidity,acidosis, occur rarely, The Merck Manuals Online Medical Librarystates. Insulin must be carefully calibrated or blood glucose levelsmay drop too low, a condition called hypoglycemia. Taking insulinwithout eating or taking too much insulin for the amount of foodeaten can cause hypoglycemia. Symptoms of hypoglycemia includeweakness, shakiness, sweating, lightheadedness and confusion;coma and death can result in severe cases.

Too little cortisol? (Addison's disease)
What Causes Addison's Disease?Result from a problem with the adrenal glands themselves (primary adrenal insufficiency).Autoimmune disease accounts for 70% of Addison's disease. This occurs when the body's immune system mistakenly attacks the adrenal glands. Thisautoimmune assault destroys the outer layer of the glands.When glucocorticoids are in use, especially in higher dose and long term therapy-the adrenalglands shrink/atrophyIf we taper clients off glucocorticoids, then adrenal glands return to normal function.If we suddenly stop the glucocorticoids, we have Addison's Crisis, the client will start losing thereblood pressure, have renal failure, be very tired and lethargic, have nausea and vomiting,asthenia (lack of strength), they will die without getting a dose of glucocorticoids
Too much cortisol? (Cushing's syndrome)
Body is exposed to high levels of the hormone cortisol for a long time. Themost common cause of Cushing syndrome, sometimes calledhypercortisolism, is the use of oral corticosteroid medication. The conditioncan also occur when your body makes too much cortisol.Causes? pituitary adenoma, tumor: lungs, pancreas, thyroid or thymus gland.

What can help balance the side effects? give them together
What if NO improvement in a week withH2 blockers??
increase dose or change to PPI
what if that happens maintenance tx needed (use lower dosethan initial tx)
WHAT is ADH?
ADH = maintain fluid balance, control BP, and cardiac output inyour body. Antidiuretic - holds fluidsDiuretics allow fluids to be lost through the kidneys
Hypothalamus sense if the plasma volume has decreased, if the Nalevel has risen (or the osmolality of the blood) and will send ADHto increase the amount of fluid retained by the kidneys.
