• Bile-malabsorption-caused diarrhea

Question 10

resin/bile sequestrant MOA

Answer 10

increase bile acid excretion

induce LDL receptors

Question 11

Resins are (A) tolerated. should be avoided in patients with (B) or (C)

Answer 11

A- Well tolerated
B-diverticulitis bc can cause constipation
C- high VLDL bc can increase VLDL

Question 12

Answer 12

A- sterol
B- NPC1L1
C-LDL

Question 13

Ezetimibe can replace (A) if patients have too many side effects… ie (B)

Answer 13

can replace statins, if patients experience myopathy etc

Question 14

If statins are at max dosing, you can give injectable (A) inhibitors like (B)

Answer 14

A- PCSK9 inhibitors

B- alirocumab*(praluent)

Question 15

PCSK9 inhibitors work by …

Answer 15

inhibiting PCKS9 inhibits the body’s natural inhibitor of LDL receptors.. making more LDL receptors available for LDL removal

Question 16

PCSK9 inhibitors are especially useful in which inherited disorders?

Answer 16

Adjunctive therapy, especially for those with heterozygous or homozygous familial hypercholesterolemia

Question 17

Fibrates are indicated in …

Answer 17

hyperTRIGLYCeridemia

1st LINE

Question 18

Fibrates lower (A) by increasing (B) and decreasing (C). They increase (D) by increasing the synthesis of (E)

Answer 18

A) Lower VLDL
by increasing B) LPL expression and decreasing C) liver secretion

D) increase HDL by increasing E) synthesis of apo-a1

Question 19

Fenofibrate is toxic to …

Answer 19

Kidneys

Question 20

which fibrate, especially, should not be used with statins? why?

Answer 20

Adverse Effects: If used with a stain, myopathy and rhabdomyolysis are more likely (Gemfibrozil especially)

Question 21

Nicotinic acid is used to treat A and B

Answer 22

Hypercholesterolemia (combine with Statin or resin)

Hypertriglyceridemia

Question 23

Niacin will increase A/B and decrease C/D

Answer 23

increase: HDL, tPA
decrease: VLDL/LDL/Lpa

Question 24

Niacin should be combined with A or B for treating hypercholesterolemia

Answer 24

Statins or resin (bile acid sequestrants)
