4
Q

What is the mechanism of action of statins?

A

They inhibit HMG-CoA reductase that is an enzyme that helps produce liver synthesis of cholesterol. By inhibiting the enzyme, the liver decreases synthesis cholesterol and increases cholesterol receptors and uptake of LDL-C. Statins can also help promote the decrease in atherosclerotic plaques through LDL-C reuptake

Q

What is the mechanism of action of the bile-acid sequestrants?

A

Prevent reabsorption of the bile acids by binding to the bile acids when excreted into the GI tract thus increasing the need for LDL-C uptake to promote the production of bile acids in the liver

Q

What is the most common bile-acid sequestrant?

A

Colesevelam

17
Q

What is a common drug interaction with bile-acid sequestrant?

A

They can bind to other medications, thus rendering them ineffective by preventing their absorption. Take medications 1 hour prior to or 4 hours after

18
Q

What is the mechanism of action of niacin?

A

inhibits free fatty acid absorption in the tissues, inhibits cAMP and reduces VLDL and LDLs

19
Q

Why is niacin not used as much anymore?

A

It has increased cardiovascular risks such as stroke

20
Q

What is the most common medication used as a second line therapy with statins?

A

Ezetimibe (Zetia)

21
Q

What is the mechanism of action of Zetia?

A

Inhibits dietary cholesterol absorption and inhibits reabsorption of cholesterol secreted in bile

22
Q

What is a severe adverse effect of Zetia?

A

Gallstones

23
Q

What are other side effects of Zetia?

A

Myopathy/Rhabdo, pancreatitis, hepatitis, thrombocytopenia

24
Q

When is Zetia contraindicated?

A

Hepatic impairment as it can increase bioavailability

25
Q

What is the mechanism of action of the PCSK-9 Inhibitors?

A

Binds to and inhibits the PCSK-9 enzyme to free LDL receptors to promote LDL-C reduction

26
Q

What are the side effects of the PCSK-9’s?

A

hypersensitivity reactions and immunogenicity due to the development of antibodies

27
Q

When are the PCSK-9 indicated for use?

A

When patients are adherent to lifestyle modifications and on maximal stain therapy

28
Q

What is the mechanism of action for fibrates?

A

Inhibits cholesterol and triglyceride synthesis thus decreasing VLDL and LDL production and levels in the body

29
Q

What is the side effects of fibrates?

A

N/V/D, rash, abdominal pain, gallstones

30
Q

What medications are fibrates contraindicated with use?

A

Zetia as both increase the risk for gallstones

31
Q

What medications are fibrates cautioned with?

A

Warfarin as it displaces warfarin from plasma albumin and can increase free warfarin levels and increase anticoagulabiity
Statins as the two can increase myopathy risk

32
Q

What is an OTC treatment for hyperlipidemia?

A

Omega-3 Fish oil, CoQ-10
