Anti-hyperlipidaemic drugs Flashcards
What enzyme in the cholesterol synthesis pathway do Statins inhibit?
HMG-CoA reductase
First line drug for most patients with elevated cholesterol
Statins- Atorvostatin, Simvastatin
According to NICE guidelines, which drug is recommended for primary prevention of adverse cardiac events if QRISK2 score is >10%?
a. Ramipril
b. Bispoprolol
c. Verapamil
d. Atorvostatin
d. Atorvostatin
NO OTHER DRUGS are recommended for primary prevention based on estimated risk
This drug class has been shown in multiple clinical trials to reduce all cause mortality in MI/stroke patients, CABG, and PCI patients
Statins
Common side effects of statins?
Most common side effects include HA, GI upset, and muscle aches.
Can also cause elevated liver enzymes (ALT)
Rare, but serious side effect of statins?
Myopathy
Rhabomyolysis
Drug-induced hepatitis
For primary prevention of cardiovascular events, a typical starting dose of Simvastatin is ___ mg ON
40
For primary prevention of cardiovascular events, a typical starting dose of Atrovostatin is __mg OD
10
What is the “high-intensity” Simvastatin dosage for secondary prevention, after a patient has had a cardiovascular event?
80mg OD
This drug class helps to lower LDL, total cholesterol and triglycerides, and also increases HDL
Statins
First line drug class for patients with very high triglycerides?
Fibrates (Bezafibrate)
MOA for Bezafibrate?
Lowers triglycerides and LDL by activation of lipoprotein lipase in the endothelium.
Also acts to raise HDL levels.
Side effects of fibrates?
GI disturbance (most common reason for discontinuation)
Myalgia/rhabdomyolysis
Which drug class acts as bile salt sequestrants, preventing re-uptake of bile salts in the gut, thereby reducing fat absorption?
Cholestyramine
Cholestyramine helps to reduce ____ but actually increases triglycerides
LDL
Side effects of Cholestyramine?
GI disturbance
Decreases absorption of fat-soluble vitamins
Name two anti-hyperlipidaemic drugs that could be used as alternatives to Statins
Ezetimibe, Cholestyramine
Which drug acts to selectively inhibit the absorption of cholesterol by the small intestine? Has a mild effect on lowering LDL
Ezetimibe
This drug can be used as an add-on to statin therapy to mildly lower LDL’s, or can be used as an alternative in statin-intolerant patients
Ezetimibe
This substance helps to reduce VLDL synthesis by the liver, and also reduces triglycerides
Fish oil
This substance inhibits lipase enzymes in adipose tissue, helping to (mildly) reduce LDL/TG. Helps to markedly raise HDL. Used for patients with very high Lp-a levels
Niacin/Nicotinic acid
(s/e: facial flushing)
