Dicyclomine Pharmacology

Dicyclomine is an anticholinergic agent that is used to help manage GI pain associated with IBS.

Dicyclomine has a very short half-life which means that it can be dosed multiple times per day.

Be careful with patients who have predominant constipation with their IBS as dicyclomine can exacerbate this.

Bentyl is the brand name of dicyclomine. This drug blocks the action of acetylcholine.

I also discuss drug interactions on the podcast, be sure to check out my latest project which is a 200+ page book on managing drug interactions in primary care.

Ondansetron Pharmacology

Ondansetron (Zofran) is a medication used for nausea and vomiting. In this episode, I lay out the pharmacology, adverse effects, drug interactions and more!

Ondansetron has been reported to increase the risk of serotonin syndrome. I discuss this further on the podcast.

Ondansetron can exacerbate QTc prolongation. Keep an eye out for patients who may have risk factors or be on other medications that can contribute to this. I discuss this further on this podcast.

Ondansetron is often used for chemotherapy induced nausea and vomiting. I discuss this and other indications on the podcast.

Budesonide Pharmacology (Oral and Rectal Formulations)

Budesonide is a corticosteroid that can be given orally or rectally for management of Crohn’s disease or ulcerative colitis.

Because budesonide has a high first pass metabolism, the relative impact of systemic effects may be less than other steroids like prednisone.

Remember that CYP3A4 inhibitors can increase the concentrations of budesonide. I discuss this further on the podcast.

Different dosage forms of budesonide (oral versus rectal) can be used for different reasons. The site of the inflammation in Ulcerative colitis can determine which dosage form is most appropriate.

Metoclopramide (Reglan) Pharmacology

Metoclopramide Pharmacology

Metoclopramide can block dopamine receptors as part of it’s mechanism of action.  I discuss the clinical implications from this in the podcast.

Metoclopramide can exacerbate Parkison’s disorder so you need to be careful in that type of patient.

Metoclopramide is dosed frequently, which can potentially be a downside as far as patient adherence goes.

Metoclopramide has a few potential interactions that you should be aware of.  I talk about those in this episode.

Be sure to check out The Thrill of the Case on Amazon as I do have a clinical scenario about Reglan (metoclopramide) in that 200+ page book.
