Hey, all, welcome back to the Real Life Pharmacology podcast. I'm your host, pharmacist, Eric Christensen,

and I thank you so much for listening today. Hopefully you pick up a few clinical pearls along the way.

And of course, speaking of clinical pearls, go check out real-life pharmacology.com. And subscribe there, and I'll give you a 30 plus page PDF on the top 200

drugs, kind of a unique little study guide that I personally put together where I lay out

important clinical pearls that you're going to see in clinical practice,

as well as things that commonly come up on board exams and things of that nature as well.

So if you've got anything to do with pharmacology, well, you're likely here for a reason.

So let's get into it with the drug of the day today.

And that is going to be teotropium.

And the brand name of this medication is Spireva.

Its primary use is in respiratory disorders.

More specifically, COPD. It's considered a long-acting anticholinergic

medication, also referred to as a long-acting muscarinic antagonist. Sometimes you'll hear the term

llama used as an acronym to kind of describe its classification.

And this drug works by essentially blocking acetycholine's action at muscarinic receptors, specifically M3 receptors or muscarinic three receptors.

And when acetylcholine binds those M3 receptors, what it leads to is bronchon constriction.

So basically that airway closing up.

And so if we prevent the cetocoline from binding those M3 receptors,

we can help cause the opposite,

which is broncholilation or that relaxation of the airway there, which obviously allows for better breathing.

Okay, so I said primary use is COPD. It can be used for asthma. It's typically a further down the

line type of medication in patients that aren't controlled
