- Ezetimibe: Inhibits cholesterol absorption.
- PCSK9 inhibitors: Help remove LDL cholesterol.
- Niacin: Raises HDL (good) cholesterol.
- Fibrates: Lower triglycerides and raise HDL.
Consult your healthcare provider to determine the most appropriate medication or combination of medications for your individual needs and health condition.
Statins: Lower LDL (bad) cholesterol.
Statins are a class of cholesterol-lowering medications that primarily target LDL (low-density lipoprotein) cholesterol, often referred to as "bad" cholesterol. Statins work by inhibiting an enzyme in the liver called HMG-CoA reductase, which is responsible for producing cholesterol. By reducing the production of cholesterol in the liver, statins effectively lower LDL cholesterol levels in the bloodstream.
- Reduce LDL cholesterol: Statins effectively lower LDL cholesterol levels by up to 50% or more, significantly reducing the risk of heart disease and stroke.
- Increase HDL cholesterol: Some statins have the added benefit of raising HDL (high-density lipoprotein) cholesterol, also known as "good" cholesterol, which helps remove cholesterol from the arteries.
- Stabilize plaque: Statins help stabilize atherosclerotic plaque, which is the buildup of cholesterol and other substances in the walls of arteries. This prevents plaque from rupturing and causing a heart attack or stroke.
- Anti-inflammatory effects: Statins possess anti-inflammatory properties that may help reduce inflammation in the arteries, further contributing to the prevention of heart disease.
Statins are generally well-tolerated, with common side effects including muscle pain, nausea, and diarrhea. However, these side effects are typically mild and usually subside over time. Statins are typically taken once daily, and it's important to adhere to the prescribed dosage and frequency to achieve optimal results.
Bile acid resins: Bind cholesterol in the gut.
Bile acid resins, also known as bile acid sequestrants, are a class of cholesterol-lowering medications that work by binding to cholesterol in the gut and preventing its absorption into the bloodstream. This process helps to reduce LDL cholesterol levels and may also modestly increase HDL cholesterol levels.
Bile acid resins work through the following mechanism:
- Cholesterol absorption: During digestion, cholesterol is broken down and absorbed into the bloodstream along with bile acids. Bile acid resins bind to cholesterol in the gut, preventing its absorption.
- Increased bile acid production: The binding of bile acid resins to cholesterol triggers the liver to produce more bile acids to compensate for the loss. This increased production of bile acids further helps to reduce cholesterol absorption.
- Excretion of cholesterol: The cholesterol-bile acid resin complex is excreted in the stool, removing cholesterol from the body.
Bile acid resins are generally well-tolerated, with common side effects including constipation, gas, and bloating. These side effects can often be managed by starting with a low dose and gradually increasing it over time. Bile acid resins are typically taken once or twice daily, and it's important to take them with meals to maximize their effectiveness.
Bile acid resins are commonly used in combination with other cholesterol-lowering medications, such as statins, to achieve optimal results. They may also be prescribed for individuals who cannot tolerate statins or have very high cholesterol levels.
Ezetimibe: Inhibits cholesterol absorption.
Ezetimibe is a cholesterol-lowering medication that works by inhibiting the absorption of cholesterol in the small intestine. It belongs to a class of drugs called cholesterol absorption inhibitors.
- Cholesterol absorption: Cholesterol is absorbed into the bloodstream from the small intestine. Ezetimibe works by blocking a protein called Niemann-Pick C1-Like 1 (NPC1L1), which is responsible for the absorption of cholesterol.
- Reduced cholesterol absorption: By blocking NPC1L1, ezetimibe prevents cholesterol from being absorbed into the bloodstream. This leads to a decrease in LDL cholesterol levels and a modest increase in HDL cholesterol levels.
- Complementary to statins: Ezetimibe is often used in combination with statins, which work by reducing the production of cholesterol in the liver. This combination therapy can be effective in lowering LDL cholesterol levels even further.
- Generally well-tolerated: Ezetimibe is generally well-tolerated, with common side effects including headache, diarrhea, and abdominal pain. These side effects are typically mild and usually go away over time.
Ezetimibe is typically taken once daily, with or without food. It is important to take ezetimibe exactly as prescribed by your doctor to achieve optimal results. Ezetimibe may be an option for individuals who cannot tolerate statins or have very high cholesterol levels.
PCSK9 inhibitors: Help remove LDL cholesterol.
PCSK9 inhibitors are a class of cholesterol-lowering medications that work by targeting a protein called proprotein convertase subtilisin/kexin type 9 (PCSK9). PCSK9 plays a role in regulating the levels of LDL cholesterol in the bloodstream.
- PCSK9 and LDL cholesterol: PCSK9 binds to LDL receptors on the surface of liver cells and prevents them from removing LDL cholesterol from the bloodstream. This results in higher levels of LDL cholesterol.
- PCSK9 inhibitors: PCSK9 inhibitors bind to PCSK9 and prevent it from binding to LDL receptors. This allows the LDL receptors to remove more LDL cholesterol from the bloodstream, leading to lower LDL cholesterol levels.
- Potent LDL reduction: PCSK9 inhibitors are very effective at lowering LDL cholesterol levels, typically reducing them by 50% or more. They can also increase HDL cholesterol levels and reduce triglycerides.
- Injectable medication: PCSK9 inhibitors are administered as an injection, typically every two or four weeks. This may be a drawback for some individuals who prefer oral medications.
PCSK9 inhibitors are generally well-tolerated, with common side effects including injection site reactions, muscle pain, and fatigue. These side effects are typically mild and usually go away over time. PCSK9 inhibitors are typically used in combination with other cholesterol-lowering medications, such as statins, to achieve optimal results. They may also be prescribed for individuals who cannot tolerate statins or have very high cholesterol levels.
Niacin: Raises HDL (good) cholesterol.
Niacin, also known as vitamin B3, is a cholesterol-lowering medication that works by raising HDL cholesterol levels and lowering triglycerides. It belongs to a class of drugs called nicotinic acid derivatives.
Niacin raises HDL cholesterol through the following mechanisms:
- Inhibition of CETP: Niacin inhibits an enzyme called cholesteryl ester transfer protein (CETP). CETP transfers cholesterol from HDL particles to LDL and VLDL particles. By inhibiting CETP, niacin reduces the transfer of cholesterol from HDL to other lipoproteins, resulting in higher HDL cholesterol levels.
- Increased HDL production: Niacin also increases the production of HDL particles by the liver. This further contributes to higher HDL cholesterol levels.
In addition to raising HDL cholesterol, niacin can also lower triglycerides, another type of fat in the blood. Niacin works by reducing the production of triglycerides in the liver and increasing the breakdown of triglycerides in the bloodstream.
Niacin is typically taken once or twice daily, with or without food. It is important to take niacin exactly as prescribed by your doctor to achieve optimal results. Niacin may cause side effects such as flushing, itching, and nausea. These side effects are usually mild and go away over time. Niacin may also interact with other medications, so it is important to tell your doctor about all medications you are taking.
Fibrates: Lower triglycerides and raise HDL.
Fibrates are a class of cholesterol-lowering medications that primarily work by lowering triglycerides and raising HDL cholesterol levels. They are commonly used to treat high triglyceride levels and low HDL cholesterol levels.
- Activation of PPARα: Fibrates work by activating a nuclear receptor called peroxisome proliferator-activated receptor alpha (PPARα). PPARα is involved in regulating the metabolism of fats in the body.
- Reduced triglyceride production: Activation of PPARα by fibrates reduces the production of triglycerides in the liver. This leads to lower levels of triglycerides in the bloodstream.
- Increased lipoprotein lipase activity: Fibrates also increase the activity of an enzyme called lipoprotein lipase (LPL). LPL breaks down triglycerides in lipoproteins, allowing them to be removed from the bloodstream.
- Increased HDL cholesterol: Fibrates increase the levels of HDL cholesterol, which helps to remove cholesterol from the arteries and transport it back to the liver for elimination.
Fibrates are generally well-tolerated, with common side effects including stomach upset, nausea, and diarrhea. These side effects are typically mild and usually go away over time. Fibrates are typically taken once or twice daily, with or without food. It is important to take fibrates exactly as prescribed by your doctor to achieve optimal results. Fibrates may interact with other medications, so it is important to tell your doctor about all medications you are taking.
