Antihyperlipidemics - Bile acid sequestrants and cholesterol absorption inhibitors: Nursing pharmacology

Anti-hyperlipidemics are medications used to treat increased levels of lipids in the blood like cholesterol, particularly low density lipoprotein or LDL cholesterol, as well as triglycerides.

Therefore, they're also indicated in coronary artery disease therapy. Anti-hyperlipidemics include different classes of medications among which are bile acid sequestrants like cholestyramine, cholescevolam, and cholestopol, as well as cholesterol absorption inhibitors like azetimib.

All of them are administered orally. Once administered, bile acid sequestrants, which are positively charged molecules, bind to the negatively charged bile acid in the intestine, preventing it from being reabsorbed.

In turn, the liver compensates by increasing the production of bile salts, which uses up a lot of cholesterol. To get more cholesterol from the rest of the body, the liver increases uptake of LDLs, lowering its levels in the blood.

The downside is that this also increases endogenous cholesterol and triglyceride synthesis. And then cholesterol absorption inhibitors work by blocking a transport protein that mediates cholesterol absorption in the small intestine.

This medication is mainly used to treat high levels of LDL and is typically used in combination with other lipid lowering agents like statins.

Common side effects of bile acid sequestrants include gastrointestinal disturbances, mostly constipation, abdominal pain, bloating, and nausea, and they can decrease absorption of fat soluble vitamins such as A, D, E, and K.

And with decreased Vitamin K absorption, increased bleeding risk can ensue. Similarly, all bile acid sequestrants can decrease the absorption and effect of fat soluble medications like digoxin, oral contraceptives, and warfarin.

Side effects of azetimib include headache, arthralgias, and myalgias, and rarely rhabdomyolysis. As far as contraindications go, bile acid sequestrants shouldn't be used in clients with complete biliary obstruction or hypertriglyceridemia, and cholocevolum in particular shouldn't be used in clients with a history of bowel obstruction, type one diabetes, or pancreatitis.

Cholestyramine should also be used with caution during pregnancy and in clients with renal impairment. Azetimib is contraindicated in clients with severe hepatic disease who are also taking a statin and should be used with caution when renal impairment is present.

All right, if a client with dyslipidemia is prescribed a bile acid sequestrant like a cholocevee as part of their anti-hyperlipidemic therapy, start by performing a baseline assessment, including vital signs, current nutritional habits, and cardiovascular status, making notes of any signs of coronary artery disease such as chest pain or shortness of breath.

Lastly, review your client's laboratory test results, including renal and hepatic function, blood glucose, and lipid panel, which includes total cholesterol, triglycerides, HDL and LDL.

Now moving on to client education, explain how the medication will help to lower their LDL and triglyceride levels, which help to decrease their risk of cardiovascular events.

Then instruct your client to take their medication with meals and a full glass of water. If the medication is in the form of granules, teach your client to empty the packet into a cup.

Mix the medication with at least 8 ounces of liquid like water or fruit juice, and to drink all of the liquid immediately.

Also, let them know to take vitamins and other medications at least 4 hours before taking their colacevee. Next, encourage lifestyle modifications that can help reduce their risk of cardiovascular events such as smoking cessation, weight control, increased physical activity, as well as a diet high in fiber and low in saturated fat and cholesterol.

Then let your client know about common side effects that they may experience during therapy and how to manage them. If your client experiences nausea, recommend small frequent meals.

In addition, teach them that the risk of constipation can be reduced by increasing their daily intake of fluid, fiber, and physical activity as tolerated.

Additionally, advise your client to report symptoms of pancreatitis, including abdominal or back pain, especially if the pain feels worse after eating.

Finally, during the course of therapy with an anti-hyperlipidemic like colocevolam, be sure to monitor your client for side effects and obtain periodic lipid profile tests to evaluate for the desired therapeutic effects of decreased LDL and triglycerides.

All right, as a quick recap, anti-hyperlipidemics are medications used to treat increased levels of lipids in the blood like LDL cholesterol and triglycerides.

These medications include bile acid sequestrants and cholesterol absorption inhibitors. Bile acid sequestrants bind to the negatively charged bile acid in the intestine, preventing it from being reabsorbed.

In turn, the liver compensates by increasing the production of bile salts and increasing uptake of LDLs. The most common side effects of bile acid sequestrants are constipation and decreased absorption of fat soluble vitamins.

On the other hand, cholesterol absorption inhibitors work by blocking a transport protein that mediates cholesterol absorption in the small intestine, and common side effects include headache, arthralgias, and myalgias.

When caring for a client taking bile acid sequestrant or cholesterol absorption inhibitor, nursing considerations include performing a baseline assessment, monitoring for side effects, and evaluating for the desired therapeutic effect of the medication.

Client teaching is focused on safe self-administration and learning to recognize and manage side effects.
