Additional Pharmacology Flashcards

 


 

Cards

Term
CHD Risk Equivalents
Definition

1.  DM

2.  Peripheral Artery Dz

3.  Abdominal Aortic Aneurysm

4.  Symptomatic carotid artery dz

5.  multiple risk factors conferring a 10yr risk for coronary heart dz greater than 20%

Term

Major CHD risk factors

(use for Framingham)

Definition

current cigarette smoking

HTN (BP ≥140/90 or if on anti-HTN)

Low HDL

fam hx (males less than 55, females less than 65)

male  ≥45

female  ≥55 or premature menopause w/out ERT

 

*if HDL  ≥60 you can subtract one risk factor!

Term
causes of secondary dyslipidemia
Definition

1.  DM

2.  hypothyroidism

3.  obstructive liver dz

4.  chronic renal failure

5.  drugs that increase LDL and decrease HDL

(steroids, corticosteroids, EtOH, BB, protease inhibitors (for HIV tx), isotretinoin, progestins, thiazide diuretics)

Term

TLC steps

 

(healthy diet, weight reduction, increased physical activity)

Definition

Visit 1:  begin TLC

                                              6wks later

Visit 2:  eval LDL response- if goal not reached intensify LDL-lowering therapy (consider adding plant stanols/sterols and fiber)

                                             6wks later

Visit 3:  eval LDL response- if goal not reached consider adding drug tx

 

6wks again to next visit, once goal reached every 4-6mo

Term

HMG Co A Reductase Inhibitors

 

"statins"

Definition

all end in "astatin"

-atorvastatin (lipitor):  best at lowering TG, also very good at dec LDL

10-100mg qday

 

non-linear dose relationship

taken in evening usu greater effect on LDLs

decreases CV morbidity/mortality (simva- and prava-)

decreases stroke incidence

Term
AE of statins
Definition

MC!  myopathy:  1 in 10 pt report myalgia, myositis, rhabdomyloysis; inc with high dose of simvastatin

 

hepatic toxicity:  elevated transaminases

 

neuropathy

Term
contraindications of statins
Definition

-pregnancy (X) and lactation

 

-active/chronic liver dz

 

-concomitant use of CSA, gemfibrozil, niacin

*increases risk of myositis

Term
drug intrxns with statins
Definition

reports of myopathy with:  CSA, gemfibrozil, clofibrate, niacin, azole, antifungal, erythromycin, nefazodone, protease inhiitors

 

-may potentiate oral anti-coag

-increased effect/toxicity of levothyroxine

 

from most to least drug intrxn

Lova-,Simva- > Atorva- > Fluva-, Pitava-, Prava-, Rosuva-

Term
bile acid resins
Definition

cholestyramine

colestipol

colesevelam

 

not as good as statins, may actually inc TGs via inc hepatic VLDL production

-good for people with moderately high LDLs

-works well with statins, can be used with niacin and fibric acids

-strong safety and efficacy record (not absorbed in GI so no systemic toxicity)

Term
AE of bile acid resins
Definition

GI:  constipation, belching, flatulence, abdominal distension, nausea, heartburn

-start with lower dose and titrate up or increase fluid and fiber intake

Term
drug interactions of bile acid resins
Definition

basically assume decreases absorption of everything until proven otherwise

*take other meds 1 hour before or 4-6hours after!

 

decreases bioavailability of statins

Term
contraindications of bile acid resins
Definition

pt w/ hx of dysbetalipoproteinemia

 

pt w/ hx of severe constipation

 

not for use as monotherapy in pt with TGs > 500 

Term
fibric acids
Definition

Fenofibrate (Tricor), Gemfibrozil

 

really good at lowering TG and comparable with statins at increasing HDL

 

good for combined dyslipidemia

 

decreases major coronary events but NO significant decrease in mortality

Term
AE and drug intrxns of fenofibrate
Definition

AE:

-GI MC!

-can increase bile lithogenicity

 

drug intrxns:

-may potentiate warfarin (anti-coag)

-avoid with statins (increased risk of myositis)

Term
Nicotinic Acids
Definition

Niacor and Niaspan 1-2g tid

 

favorable effects on all lipids/lipoproteins:  best at increasing HDL and ties fibric acids at decreasing TG

 

start slow, go slow, monitor for hepatic toxicity

 

decrease major coronary events and CHD deaths

 

Term
AE and CI of nicotinic acids
Definition

AE:

-flushing MC!

-may cause glucose intolerance and increase uric acid

-older versions have caused fulminant hepatitis (Niaspan better tolerated)

 

CONTRAINDICATIONS:

-liver dz!

-DM2

-gout

-hyperuricemia

Term
drug intrxns nicotinic acids
Definition

decreased effect of oral hypoglycemics

 

may inhibit uricosuric effects of sulfinphyrazone and probenecid (inhibits uric acid elimination)

 

increased toxicity (myopathy) with lovastatin and possibly other statins

 

may potentiate anti-HTN meds

Term
2-Azetidione
Definition

Ezetimibe (Zetia)

 

AE:  monotherapy:  fatigue, abdominal pain, diarrhea, arthralgia, back pain

with statin:  above + HA and myalgia

 

contraindications:  do not combo with statins in active liver dz or in pt w/ persistent LFT elevations

Term
drug interactions of 2-Azetidione
Definition

drug intrxns:  decreased absorption when given w/ cholestyramine (bile acid);

-give 2hr before or 4hr after cholestyramine

 

-Ezetimibe levels may increase when taken with gemfibrozil, cyclosporine

 

-combo-ed with statins works well

 

Term
supplements for lowering cholesterol
Definition

plant stanol esters

 

fish oils (omega-3 fatty acids), EPA, DHA over AHA

 

other therapies:

blond psyllium

oat bran

Term
progression of drug therapy in primary prevention of hyperlipidemia
Definition

statin (or BAR or nicotinic acid)

                                                 6wks later

if goal not met:  consider increasing statin dose or add BAR/nicotinic acid

                                                 6wks later

still not met:  intensify therapy or refer to lipid specialist

if goal met:  treat other lipid risk factors and follow up every 4-6 months

Term
what is the initial therapy for any lipid disorder
