What do Nitrates do?
VASODILATION; relax smooth muscles in blood vessles; BP
decrease afterload (diastolic)
decrease preload/resistance (systolic)
Nitrates; PT teaching for…
Sublingual
Transdermal
PO

PO - take on an empty stomach
Nitrates; WWND??
check BP
watch for O/H
HOLD if systolic is below 100; document & call Dr
head aches; admin NSAIDS - Aspirin or Analgesic - Tylenol
Nitrates; avoid…
NO ETOH or Viagra!!!
What do Calcium Channel Blockers do??
3
DEC intracellular calcium & promotes VASODILATION
DEC afterload/workload ofheart
CCB; WWND?? check/monitor
check BP, HR, RR, lung sounds
Monitor EKG
check bowels
CCB; may…
CCB WILL NOT
WORSEN contractions causing HF/arrythmias
cause CONSTIPATION
WILL NOT RELIEVE AN ACUTE ATTACK
CCB; Cardizem is to manage what arrythmias? 4
slows heart
S-Tach
SVT
A-Fib
A-Flutter
What do Beta Blockers do??
Block SNS/vasoconstriction
to DEC cardiac workload
SLOW HR
DEC contractions
DEC O2 requirements
WILL NOT PREVENT AN ACUTE ATTACK; need Nitroglycerine
Beta Blockers; given for…
& what arrythmias? 4
Angina, Hypertension
prevents SVT, V-fib
also for A-fib, A-flutter
Beta Blockers; WWND??
check HR, RR, O2; X asthma, COPD
BP (hold if under 50)
BG (mask hypoglycemia)
BB; (loPRESSor) Lopressor controls…
how would you admin??
controls ventricle rate
5mg IV push
Reductase Inhibitors/Statins; WDTD?
Drugs
block enzymes HMG-CoA; lowers cholesterols
ZOCOR
Reductase/Statins; Monitor…
LFTs (activates in liver) Muscle weakness/CRAMPS/Rhabdomyolysis CPK levels (tissue injury)
Reductase/Statins; PT teaching & Drug Interactions
Take in evening (when you make lipids)
Avoid ETOH
D/I: erythromyocin (abx for skin/acne), grapefruit juice - inc risk of myopathy
Bile Acid Sequestrants; Questran
WDTD?
Bind with bile acids in interstitial lumen to lower LDL
Bile Acid Sequestrants;Questran
PT teaching - drug interactions
THERE ARE A LOT!! decreases absorption of other medications, TAKE 1 HR BEFORE or 4-6 HRS AFTER
