Which enzyme is the primary target of statin drugs?
HMG-CoA reductase
Lipoprotein lipase
Cholesterol 7?-hydroxylase
Acetyl-CoA carboxylase
Statins competitively inhibit HMG-CoA reductase, the rate-limiting enzyme in hepatic cholesterol synthesis. This inhibition reduces intracellular cholesterol and increases LDL receptor expression on hepatocytes. Enhanced receptor-mediated uptake lowers circulating LDL levels. Wikipedia
Which lipid parameter is most significantly reduced by high-intensity statin therapy?
High-density lipoprotein cholesterol
Low-density lipoprotein cholesterol
Triglycerides
Lipoprotein(a)
High-intensity statins primarily target LDL cholesterol, achieving reductions of 50% or more. They have modest effects on triglycerides and slight increases in HDL. Lipoprotein(a) is not significantly affected by statin therapy. AHA Guidelines
What is the main physiological role of low-density lipoprotein (LDL)?
Transport triglycerides from liver to adipose tissue
Deliver cholesterol to peripheral tissues
Carry fat-soluble vitamins to the intestines
Reverse cholesterol transport to liver
LDL particles are responsible for delivering cholesterol to peripheral tissues and cells. They originate from VLDL remnants after triglyceride removal. Excessive LDL cholesterol contributes to atherosclerotic plaque formation. Wikipedia
Which mechanism best describes how bile acid sequestrants lower cholesterol?
Inhibit HMG-CoA reductase in the liver
Bind bile acids in the intestine and prevent reabsorption
Block cholesterol absorption in the brush border
Activate lipoprotein lipase to degrade VLDL
Bile acid sequestrants bind bile acids in the gastrointestinal tract, preventing their enterohepatic recirculation. This causes the liver to convert more cholesterol into bile acids, lowering intracellular cholesterol. Reduced cholesterol increases LDL receptor expression to clear circulating LDL. Wikipedia
Niacin (vitamin B3) primarily affects lipid levels by:
Increasing LDL receptor expression
Inhibiting cholesterol absorption
Reducing hepatic VLDL synthesis and increasing HDL
Activating PPAR? to lower triglycerides
Niacin reduces VLDL synthesis in the liver, which decreases circulating triglycerides and LDL. It also increases HDL cholesterol more effectively than other agents through reduced catabolism of ApoA-I. The mechanism involves inhibition of hepatic diacylglycerol acyltransferase-2. Wikipedia
Which class of lipid-lowering drugs is most effective at lowering triglyceride levels?
Statins
Bile acid sequestrants
Fibric acid derivatives (fibrates)
Cholesterol absorption inhibitors
Fibrates activate PPAR?, increasing lipoprotein lipase activity and fatty acid oxidation, which lowers triglycerides. They can reduce triglyceride levels by 30–50%. Fibrates have modest effects on LDL and HDL levels. Wikipedia
PCSK9 inhibitors lower LDL cholesterol by which mechanism?
Inhibiting cholesterol absorption in the intestine
Blocking PCSK9-mediated degradation of LDL receptors
Increasing bile acid excretion
Activating LDL receptor gene transcription
PCSK9 inhibitors are monoclonal antibodies that prevent PCSK9 from binding to LDL receptors. This reduces receptor degradation and increases clearance of LDL cholesterol from the blood. They can lower LDL by up to 60% when added to statins. Wikipedia
Ezetimibe lowers plasma cholesterol by:
Inhibiting intestinal absorption of cholesterol
Increasing hepatic cholesterol synthesis
Enhancing bile acid reabsorption
Stimulating LDL receptor degradation
Ezetimibe selectively inhibits NPC1L1 transporter at the intestinal brush border, reducing dietary and biliary cholesterol absorption. Lower cholesterol delivery to the liver upregulates LDL receptors, decreasing circulating LDL. It reduces LDL by around 18–20%. Wikipedia
Which laboratory measurement is considered a good surrogate marker for residual cardiovascular risk after statin therapy?
LDL cholesterol
High-density lipoprotein cholesterol
Non–high-density lipoprotein cholesterol
Apolipoprotein B
Non–HDL cholesterol includes LDL, VLDL, and other atherogenic lipoproteins, making it a strong predictor of residual cardiovascular risk. It is calculated by subtracting HDL from total cholesterol. Guidelines recommend non–HDL as a secondary target after LDL in hypertriglyceridemia. PMC Article
What is the most common adverse effect associated with statin therapy?
Elevated liver enzymes
Myalgia
Gastrointestinal bleeding
Neuropathy
Statin-associated myalgia is the most commonly reported side effect, characterized by muscle aches or weakness often without significant CK elevation. Elevated liver enzymes can occur but are less common, and severe myopathy is rare. Monitoring and dose adjustment helps manage muscle symptoms. AHA Statement
Approximately what percentage reduction in LDL cholesterol is expected with high-dose atorvastatin 80 mg daily?
20%
50%
80%
35%
High-dose atorvastatin (40–80 mg) can reduce LDL cholesterol by about 50%. This places it in the high-intensity statin category per ACC/AHA guidelines. Lower doses yield smaller reductions. ACC/AHA Guidelines
Fenofibrate lowers triglycerides primarily through activation of which nuclear receptor?
Liver X receptor (LXR)
Peroxisome proliferator-activated receptor alpha (PPAR?)
Pregnane X receptor (PXR)
Farnesoid X receptor (FXR)
Fibrates, such as fenofibrate, activate PPAR?, which increases transcription of genes involved in fatty acid oxidation and lipoprotein lipase activity. This reduces hepatic triglyceride production and enhances clearance. They also modestly increase HDL cholesterol. PMC Article
Which of the following is a common side effect of niacin that often limits its use?
Facial flushing
Tinnitus
Insomnia
Cough
Niacin causes prostaglandin-mediated vasodilation leading to facial flushing in most patients. Pre-treatment with aspirin can reduce this effect. Flushing often results in poor compliance, limiting niacin’s clinical use. PMC Article
Which of the following is a bile acid sequestrant used in clinical practice?
Cholestyramine
Ezetimibe
Niacin
Alirocumab
Cholestyramine is a first-generation bile acid sequestrant that binds bile acids in the gut. Other agents in this class include colestipol and colesevelam. They are used to reduce LDL cholesterol, particularly in statin-intolerant patients. NCBI
Which condition is a contraindication to initiating statin therapy?
Active liver disease
Type 2 diabetes mellitus
Hypertension
Stable angina
Active liver disease or unexplained persistent elevations in hepatic transaminases are contraindications to statin use due to potential hepatotoxicity. Diabetes, hypertension, and stable angina are indications rather than contraindications. Baseline liver function tests are recommended before therapy. FDA Guidance
How do statins upregulate LDL receptor expression on hepatocytes?
By decreasing intracellular cholesterol, activating SREBP
By increasing bile acid synthesis directly
By inhibiting NPC1L1 transporters
By enhancing CETP activity
Statins inhibit HMG-CoA reductase, reducing intracellular cholesterol. Low cholesterol levels activate SREBP transcription factors, which increase LDL receptor gene expression. More LDL receptors on hepatocytes enhance clearance of LDL from circulation. Wikipedia
What is the primary benefit of combining ezetimibe with a statin?
Greater LDL cholesterol reduction than statin alone
Enhanced triglyceride lowering
Increased HDL cholesterol significantly
Lower risk of statin-induced myopathy
Adding ezetimibe to statin therapy reduces LDL cholesterol by an additional 15–20% compared with statin alone. Ezetimibe inhibits cholesterol absorption, complementing statin-mediated synthesis inhibition. This combination is used when LDL goals are not met on statins alone. PMC Article
Lipoprotein(a) differs from LDL by the addition of which apolipoprotein?
Apolipoprotein C-II
Apolipoprotein E
Apolipoprotein(a)
Apolipoprotein A-I
Lipoprotein(a), or Lp(a), consists of an LDL-like particle covalently bound to apolipoprotein(a). Elevated Lp(a) is an independent risk factor for atherosclerotic cardiovascular disease. Standard lipid-lowering therapies have minimal effect on Lp(a) levels. Wikipedia
Which statin is least likely to interact with CYP450-metabolized drugs like warfarin?
Simvastatin
Atorvastatin
Pravastatin
Lovastatin
Pravastatin is hydrophilic and undergoes minimal CYP450 metabolism, reducing drug–drug interactions. In contrast, simvastatin, atorvastatin, and lovastatin are metabolized by CYP3A4. This makes pravastatin safer in patients on multiple CYP-metabolized drugs. PMC Article
Familial hypercholesterolemia is most commonly inherited in which pattern?
Autosomal dominant
X-linked recessive
Mitochondrial
Autosomal recessive
Heterozygous familial hypercholesterolemia is inherited in an autosomal dominant pattern due to mutations in the LDL receptor gene. Homozygous forms are rare and more severe. Early diagnosis and aggressive lipid-lowering are essential. PMC Article
Compared to statins, fibrates have a greater effect on lowering:
High-density lipoprotein cholesterol
Triglycerides
Low-density lipoprotein cholesterol
Total cholesterol
Fibrates reduce triglyceride levels by 30–50% through PPAR? activation, whereas statins typically lower triglycerides by only 10–30%. Statins primarily target LDL cholesterol. Fibrates also modestly increase HDL levels. PMC Article
PCSK9 inhibitors are indicated for patients with heterozygous familial hypercholesterolemia who:
Have LDL-C <70 mg/dL on maximal statin therapy
Have clinical ASCVD and LDL-C above goal despite maximal statin therapy
Are on primary prevention with no other risk factors
Have homozygous FH already on apheresis
PCSK9 inhibitors like evolocumab and alirocumab are approved for clinical ASCVD patients who have LDL cholesterol above goal despite maximal statin therapy, including those with heterozygous FH. They provide additional LDL lowering when other therapies are insufficient. FDA Guidance
Which cholesteryl ester transfer protein (CETP) inhibitor was withdrawn due to increased mortality and off-target effects?
Torcetrapib
Anacetrapib
Evacetrapib
Dalcetrapib
Torcetrapib raised HDL cholesterol but also increased blood pressure and mortality, leading to its withdrawal. Anacetrapib, evacetrapib, and dalcetrapib have different profiles but were halted for lack of efficacy or safety concerns. CETP inhibition remains investigational. Nature
Lomitapide lowers LDL cholesterol by inhibiting which protein?
Microsomal triglyceride transfer protein
NPC1L1 transporter
PCSK9
Cholesterol ester transfer protein
Lomitapide inhibits microsomal triglyceride transfer protein (MTP) in the liver and intestine, preventing assembly of apoB-containing lipoproteins. This reduces VLDL secretion and lowers LDL cholesterol. It is used in homozygous familial hypercholesterolemia. Wikipedia
Inclisiran reduces LDL cholesterol through what mechanism?
siRNA inhibiting PCSK9 synthesis in hepatocytes
Monoclonal antibody against PCSK9
Small-molecule PCSK9 inhibitor
CETP activator
Inclisiran is an siRNA therapy that targets PCSK9 mRNA in hepatocytes, reducing PCSK9 protein synthesis. This leads to increased LDL receptor availability and lower LDL cholesterol. It requires infrequent dosing due to its long duration of action. NEJM
Volanesorsen is an antisense oligonucleotide that targets the mRNA of which protein?
Apolipoprotein C-III
Apolipoprotein A-I
Apolipoprotein B
Apolipoprotein E
Volanesorsen binds to apolipoprotein C-III (APOC3) mRNA, reducing its translation. Lower ApoC-III levels enhance lipoprotein lipase activity and clearance of triglyceride-rich particles. It is used for familial chylomicronemia syndrome. FDA
Evinacumab is a monoclonal antibody targeting which protein to lower lipid levels?
Angiopoietin-like protein 3 (ANGPTL3)
PCSK9
CETP
HMG-CoA reductase
Evinacumab inhibits ANGPTL3, a regulator of lipoprotein lipase and endothelial lipase. Blocking ANGPTL3 reduces triglycerides, LDL, and HDL levels. It is approved for homozygous familial hypercholesterolemia. PMC Article
A genetic polymorphism in which gene is associated with higher risk of statin-induced myopathy?
SLCO1B1
CYP3A4
HMGCR
LDLR
Variants in SLCO1B1, especially c.521T>C, reduce hepatic uptake of statins and increase systemic exposure, raising myopathy risk. Genetic testing can guide safer dosing. This is a key pharmacogenomic marker. PMC Article
CRISPR/Cas9 gene editing targeting PCSK9 has demonstrated significant LDL reduction in which model?
Mouse models
Human clinical trials
In vitro cell lines only
Non-human primates
In vivo CRISPR/Cas9 editing of the PCSK9 gene in mouse liver significantly lowered LDL cholesterol in preclinical studies. This proof-of-concept has not yet advanced to human trials. It illustrates potential for genome editing in lipid disorders. Nature
Which viral vector was used in the first approved gene therapy for lipoprotein lipase deficiency (Glybera)?
Adeno-associated virus serotype 1 (AAV1)
Lentivirus
Adenovirus
Retrovirus
Glybera used an AAV1 vector to deliver the lipoprotein lipase gene to muscle cells. It was the first gene therapy approved in Europe for LPL deficiency. AAV vectors offer long-term expression with low immunogenicity. Wikipedia

Cheat Sheet

  1. Statin Mechanism & High-Intensity Regimens -

    Statins inhibit HMG-CoA reductase, reducing cholesterol synthesis and upregulating LDL receptors, which can lower LDL by ≥50% (ACC/AHA 2018). High-intensity regimens - atorvastatin 40 - 80 mg or rosuvastatin 20 - 40 mg - are essential for high-risk patients and frequent exam topics in a hyperlipidemia quiz. Recall "A2R1" (2× Atorva, 1× Rosuva) to remember dose tiers and ace statin therapy questions!

  2. Friedewald Equation for LDL Calculation -

    The Friedewald formula estimates LDL-C as Total Cholesterol - HDL-C - (Triglycerides/5) when TG is <400 mg/dL (NIH). Mastering this calculation is vital for any lipid management quiz and ensures accurate patient lipid profiles. Tip: memorize "LDL = TC - HD[lean] - TG/5," to breeze through cholesterol medication quiz problems!

  3. Fibrate Actions & Clinical Pearls -

    Fibrates activate PPAR-α to boost lipoprotein lipase activity, reducing triglycerides by 30 - 50% and modestly raising HDL (Journal of Lipid Research). Gemfibrozil 600 mg BID and fenofibrate 145 mg daily carry gallstone and statin-interaction risks, a frequent point in hyperlipidemia pharmacotherapy tests. Use the mnemonic "Fibs Burn Fat" to lock in this class's key effect!

  4. PCSK9 Inhibitor Mechanism & Dosing -

    PCSK9 monoclonal antibodies like evolocumab and alirocumab prevent LDL receptor degradation, increasing clearance and cutting LDL by up to 60% (NEJM). Typical dosing is evolocumab 140 mg biweekly or 420 mg monthly, a high-yield point for your cholesterol medication quiz. Remember "Pro-Cut" (PCSK9 Cuts Pro receptors) to recall how receptor recycling boosts LDL uptake!

  5. Bile Acid Sequestrants & Dosing Tips -

    Agents like cholestyramine and colesevelam bind bile acids in the gut, lowering LDL by 15 - 30% but can raise triglycerides and cause GI upset (AHA guidelines). Dosing often starts at cholestyramine 4 g once daily, titrated up to 24 g/day split doses - watch for fat-soluble vitamin malabsorption and bulky pills. Mnemonic: "Bile Bags Bind Bad" to cement their lipid-lowering niche for your lipid management quiz!
