Pharm Final Flashcards
Thiazide depletes
potassium (fatigue)
What antihyperlipidemia drug is water soluble and inhibits lipolysis in adipose tissue
niacin (decr liver triglycerides and lower VLDL and LDL)
Skin flush
Pruritis
Nausea
Ab pain
side effects of Niacin
stimualtes lipoprotein lipase to breakdown triglycerides into FFA’s and remove from plasma
clofibrate (don’t use with anticoagulant)
Condition where clofibrate is used
hypertryglyceridemia
Myositis
Gi disturbance
gall stones
side effects of clofibrate
Binds to bile acid and bile salt in SI and excreted in feces
Cholestyramine
MC HMG-CoA reductase inhibitors
lovastatin/mevacor
Misvastatin/zocor
myopathy
rhabdomyolysis
abnormal liver function
side effects of lovastatin and zocor
pregnant and nursing mothers should not take which antihyperlipidemias
lovastatin and zocor
prostaglandin synthesis:
phospholipid to arachidonic acid (via cyclooxyrgenase) to prostaglandin
prostaglandins stimulate TXA2 for
platelet aggregation
aspirin acts as anti-inflammatory by
decr prostaglandin synthesis by inhibiting cyclooxygenase
high dose of aspirin can lead to
hyperventilation and respiratory alkalosis
do all NSAIDs cause interstitial nephritis?
No. not aspirin
Hepatitis w/ cerebreal edema is caused by chicken pox and aspirin: name syndrome
reyes syndrome
when is aspirin prescribed
1 antipyretic
- analgesic/antiinflammatory
- unstable angina
- coronary artery thrombosis
if patient bleeds in GIT due to aspirin use, they should be given
misoprostol/cytotec
aspirin side effects
nausea vomiting gastritis prolonged bleeding allergy metabolic acidosis reyes syndrome
lethal dose of aspirin
> 13 grams
NSAID’s that work as anti-inflammatory, analgesic, antipyretic and better than aspirin–work as potent cyclooxyrgenase inhibitors
- ibuprofen/motrin (fever)
2. naproxen/anaprox
Ibuprofen side effects
GI bleed
prolonged bleeding
*interstitial nephritis
Indomethacin is prescribed for
RA, AS, Gout
indomethacin side effects
GI bleed
*frontal HA
neutopenia
thrombocytopenia
most powerful antiinflammaotry
Phenylbutazone (weak antipyretic/analgesic)
Aplastic anemia and agranulocytosis are side effects of
phenylbutazone (RA and Gout)
acetominophen acts to
inhibit prostaglandin synthesis in CNS (weak antiinflammatory, better antipyretic and analgesic)
Tylenol vs aspirin
aspirin prolongs bleeding time, tylenol doesnt
how does acetaminophen cause liver damage
can be hydroxylated and become toxic
side effects of acetominophen
liver damage (>13g), rash
acetominophen overdose, use
N-acetylcysteine
lethal dose of aspirin for children
around 7 grams
gold salts are used for
RA and other arthritis
dermatitis could be caused by ** (WRONG: GOLD SALT)
acetominophen use
Severe RA med that is used when no other med works
methyltrexate
colchicine is used for
Gout (inhibits lipooxygenase)
chronic gout med
allopurinol
colchicine fatal dose
8mg in 24hrs
action of colchicine
binds to tubular causing depolymerization
side effects of colchicine
ab pain
nausea
vomiting
diarrhea**
action of allpurinol
decr uric acid by inhibiting xanthine oxidase
allergy/skin rashes are side effects seen with
allopurinol
median lethal dose ( LD50)
smallest dose given to kill 50% of test group
MEdian lethal concentration (LC50)
smallest concentration given to kill 50% of test group
threshold limit value
max amount considered safe
Simple asphyxants
irritants
systemic toxicants
types of gaseous poisons
most rapid acting poisons forming complex with ferric ions of cytochrome oxidase system
cyanide
breath of person poisoned with cyanide
bitter almond
cyanide antidote
amyinitrite**
cherry red cyanosis
carbon monoxide poisoning
CO is 200x more affinic than O2
true
tx for CO poisoning
100% O2
only heavy metal toxin which affects kidney
arsenic
arsenic poisoning affects on body
pale bands appear in toenails and fingers
arsenic poisoning antidote
dimercaprol
MCC heavy metal poisoning
lead via GI and inhalation
lead poisoning antidote
dimercaprol, edentate
black line on gums, lead encephalopathy are signs of
lead poisoning
