Tx Angina
N= dialte veins and decrease preload
B=decrease rate and force of contrction
C= Dilate arteriole, decrease afterload
-
Nitroglycerine
- 1st drug given for Angina
- Acts directly on vascular smooth mucsle
- Dilates veins and pulls fluid from heart, DECREASING Preload

- IV fusion - short term only
- - 5-50 ug/min
-
IV Nitro needs special tubing b/c it sticks to plastic
IV Nitro needs special tubing b/c it sticks to plastic

Diuretics
increase urine output
- -Tx of HTN
- -Mobilization of edematous fluid
- -Prevent renal failure
- =when fluids are low on this pt. we give fluids and diuretics to flush kindeys out
-
Adverse effects of diuretics
- Hypovolemia
- -dehydration, orthostatic hypoTN, thirst
- Acid/Base imbalance
- Disturbances of electrolyte levels
-
Furosemide / Lasix
- Loop (high ceiling) Diuretic
- Works in the Ascending loop of Henle
- -depends on prostaglandin availability (which dec. with ibuprofen use)
- Blocks Na+ and Cl- reabsoprtion
- DOC for fluid overload
SE= Hypokalemia
-
Thaizide diuretic
- Blocks Na and CL reabsorption
- ->much LESS h2o and electrolyte loss than loops
- Doesn't work well with low GFR rate, so not given for Renal Failure
- Used for HTN and Edema
- BAD for Gout (uric acid build up)
Paradoxical (reverse) effects on Diabetes Insipidus (decreases urine in a disease that increases urine
-
K+ sparing diuretic
-used with other diurs.
- Aldosterone Antagonist
- Inc. Na+ excretion so Kidney saves K+
Limited urine production but dec. K+ loss
-
Manntiol / Osmotorol
- Creates an osmotic effect in the nephron
- -inhibits passive reabsorption of h2o
- NO Metab effect, just a big molecule that attracts h2o
- Moves fuild from tissue into vascular space
- MUST be given IV and use a filter needle
- Given mainly to Dec. ICP, also used for edema
-
drugs for emergencies:
anaphylaxis
HTN
SVT
a= Epi
HTN= Nitroprusside / Nipride
SVT= Adenosine (Cardizem ?)
-
Heparin
- anti-coag
- Inactivates Thrombin and Factor 10a
- -fibrin production is reduced, clotting suppressed
- -short 1/2
- First pass effect
Used for PE, Embolic stroke, MI, DIC
Monitor a PTT (22-34 sec.)
Risk for Bleeding
-
Protamine Sulfate
Antidote for heparin induced bleeding
-
Warfarin / Coumadin
- oral anti-coag
- Vit K antagonist
Monnito r PT and INR
- risk for bleeding
- many drug reactions
-
ASA / Aspirin
- Anti-platelet
- prevent platelet aggregation
- prevent thromboses in arteries
- Interrupts clotting by interfering with Thromboxane
- SE= GI bleed
-
*Glycoprotein receptor antagonist
Anti-platelet
-reversible blocking of receptor to prevent agg
Given IV short term for ACS
-
Cilostazol / PLetal
Anti-platelet
Platelet inhibitor and vasodilator
DOC for intermittent Claudication
-
HMG-CoA Reductase and their Inhibitors
HMG reductase provides for cholest product
Inhibitors sterols --> are called Statins -> DOC for dec. LDL and inc. HDL
-
Statins
- Dec. LDL
- INc. HDL
- Promote plaque stability
- Also, an Inc in Hepatic LDL receptors
take drug at night b/c most chol production is done at night
create risk for liver failure and muscle breakdown
-
SE of Statins
Headache, rash, GI
Hepatotoxicity major SE, monitor every 6 months
Muscle inflamm and breakdown
Grapefruit juice
-
two catagpries of Asthma
inflammtion and bronchospasms
-
inflammation med choice
glucocorticoids
-
Glucocorticoids
- ***Most effective anti-asthma (anti-inflamm) drugs available
- Prophylaxis of chronic asthma
- Beneficial effects develope OVER TIME (will not help in middle of attack)
- Used on a regular schedule
must be weened off to avoid adrenal suppression
-
asthma management - IV therapy
- for acute-short term use only
- toxicity risk increases with long term
-
Oral vs. inhalation use of Glucocorticoids
- O= Adrenal suppression, bone loss
- = nl cortisol production stops by body
- = pts must be weaned off so adrenal glands pick up production
- I= oropharyngeal candidiasis and dysphonia
- = little inhaled meds reaches systemic circulation
- = changing from oral to inhale must include weaning, even if using both
-
bronchospasm med of choice
inhaled Beta 2 agonist
-
Asthma - Beta 2 agonists
- bronchodilators
- inhibit bronchospasm by relaxing smooth ms
- suppress histamine release in the lungs
-
Fluticasone / Salmeterol - Advair
Budesonide / Formotorol - Symbacort
- combo inhalers
- long term Beta agonists and inflamm agents
- Have good asthma control
-
Diet therapy for ulcers
- traditional ulcer bland diet not effective
- avoiding caffeine not effective
- eat 5-6 small meals daily
- Avoid NSAIDS and ASA
-
Histamine2 receptor blockers (type of med?)
H2 receptors
- anti-acid secretion drug
- = reduce volume and acidity of secretions
recept= parietal cells of stomach
-
What can result from long term H2 receptor blockers?
Pneumonia b/c Dec. acid means Inc. bacteria growth
-
Proton pump inhibitors
- most effective acid suppresion b/c it shuts everything down
- prevents basal and stimulated acid production
- IRREVERSIBLE
- Cancer risk with long term use
- along with pneumonia, fractures, rebound hypersecretions, and for C-Diff
-
Sucralfate / Carafate
other anti-ulcer drug
- Inert-provides viscous protective barrier b/w acid and epithelium
- May impede absorption of some drugs
-
Antacids
- Alkaline cmps that neutralize
- Stimulate production of prostaglandins
- Do not provide physical barrier
- poorly absorbed
Provide symptomatic relief for GERD
-
Laxatives
uses
- to ease of stimulate defecation
- -soften
- -increase stool volume
- -hasten fecal passage
- -facilitate evacuation
-
laxative effects
vs.
catharsis
L= mild leisurely results
C= Fast, intense effects
-
**group 1 laxative**
- watery stool in 2-6 hours
- Osmotics, Castor oil, Electrolyte solutions
used to clean bowels before surgery
-
**group 2 laxatives**
- Semi-fluid stools in 6-12 hours
- Osmotics, stimulants
used for general constipation
-
**group 3 laxatives**
- Soft stool in 1-3 DAYS
- Bulk, surfactant, lactulose
preventative
-
Bulk forming
- group 3
- Like dietary fiber
- Stretch of intestinal wall stimulates peristalsis
- Absorbs water to soften stool
-
Surfactant
- group 3
- Lower surface tension - greater water absorption
-
Stimulant
- Stimulate instestinal motility
- Inc. water and electorlyte in intestinal lumen
-
Osmotics
- Laxative Salts
- Draw water into the gut
- Poorly absorbed systemically, but high doses can cause problems for cardiac pt.s
-
Lactulose
- made of fructose and galactose
- Enhances intestinal excretion of ammonia
used for liver failure pt.s to help rid ammonia in stool
