Cholestyramine Pharmacology

On this episode, I discuss the pharmacology of cholestyramine.

Cholestyramine was originally developed as an agent to manage cholesterol, but has fallen out of favor for some of the more effective agents like statins.

Cholestyramine is notorious for binding drug interactions. It can reduce concentrations of drugs like amiodarone, digoxin, oral contraceptives, immunosuppressive and many more!

In patients with chronic diarrhea, cholestyramine is occasionally used off label to help manage symptoms because it tends to have constipating effects.

Ezetimibe Pharmacology

Ezetimibe Pharmacology

On this episode, I discuss ezetimibe pharmacology. Ezetimibe works by inhibiting Niemann-Pick C1-Like1 (NPC1L1) transporter. This transporter aids in cholesterol absorption so by blocking it, we can reduce cholesterol levels (and LDL) in the bloodstream.

Ezetimibe is usually very well tolerated. Diarrhea, myopathy, and elevations in LFT’s are adverse effects that have been reported but do not occur at high rates.

Ezetimibe is dosed at 10 mg once daily. This is a nice advantage because this is a starting dose and the usual treatment dose.

With the most recent cholesterol guideline updates, I do expect ezetimibe to be utilized a little more than it used to be. They place more emphasis on a target LDL and getting patients to goal.

Statins are going to be used first line for cholesterol and ezetimibe will be an add on therapy to consider. They don’t, unfortunately, lower cholesterol as much as high-intensity statins do.

Statin Pharmacology Episode 005

In this episode, I talk about the most commonly used statins.  In my practice I see simvastatin, atorvastatin, rosuvastatin, and pravastatin used most frequent.

In addition, I also discuss why statins are dosed at night, possible side effects, and important drug interactions.

Statins can help lower cholesterol and reduce the risk of cardiovascular events like heart attack.  I mentioned cvriskcalculator.com on the podcast and wanted to give that link to you.
