16
Q

What are the adverse effects of ezetimibe?

A

diarrhoea, abdominal pain, headache

17
Q

Give examples of drugs that inhibit cholesterol absorption

A

bile acid binding resins, ezetimibe

18
Q

What do low density lipoproteins cause?

A

atherosclerosis

19
Q

What are the other benefits of statins?

A

decreased inflammation, reversal of endothelial dysfunction, decreased thrombosis, stabilisation of atherosclerotic plaques

20
Q

What is the role of high density lipoprotein?

A

removes cholesterol from cells - transports it to the liver where it is broken down

21
Q

What are fibrates used for?

A

first line to decrease triglycerides, modest decrease in LDL, modest increase in HDL

22
Q

How are bile acid binding resins administered?

A

orally

23
Q

What is dyslipidaemia?

A

high levels of LDL and/or low levels of HDL, increases risk of CHD and stroke

24
Q

What is the mechanism of action of statins?

A

competitive inhibitors of enzyme responsible for cholesterol synthesis in hepatocytes

25
Q

What is the mechanism of action of ezetimibe?

A

reduces absorption of cholesterol, decreases LDL
