Famotidine Pharmacology Podcast

On this podcast episode, I discuss famotidine pharmacology, adverse effects, uses, and drug interactions.

Famotidine is generally pretty well tolerated, but one thing I look out for with chronic use is B12 deficiency.

Famotidine is eliminated by the kidney so you should pay attention to the dose in patients with CKD.

Famotidine is occasionally used as a pretreatment to help prevent infusion-type reactions for certain chemotherapy agents.

Lactulose Pharmacology

Lactulose is an osmotic laxative but it is rarely used for this purpose. I discuss lactulose pharmacology in this episode.

Elevated ammonia levels are an issue in hepatic encephalopathy. Lactulose can help manage this issue.

Lactulose is dosed to 2-3 soft stools per day when used to reduce ammonia levels.

Lactulose can increase the effect of warfarin and raise INR; I discuss this further on this episode.

Lansoprazole Pharmacology

Lansoprazole is a proton pump inhibitor that can be commonly used for GERD, PUD, and GI prophylaxis.

Lansoprazole can inhibit CYP2C19 which can cause concentrations of drugs like escitalopram and citalopram to rise.

Hypomagnesemia, low B12, osteoporosis, and an increase in C. Diff risk are potential complications with longer-term PPI use.

PPIs like lansoprazole are best given 30-60 minutes before meals. This is something that patients often forget.

Esomeprazole (Nexium) Pharmacology

On this episode, I discuss esomeprazole (Nexium) pharmacology, adverse effects, tapering, kinetics, and drug interactions.

I spend a good amount of time discussing the esomeprazole and clopidogrel interaction in this podcast episode.

Esomeprazole inhibits CYP2C19. This can cause an increase in citalopram concentrations and raise the potential for QTc prolongation.

It is critical to reassess the length of therapy and the dose of PPIs like esomeprazole.

Sucralfate Pharmacology

On this episode, I discuss (Carafate) sucralfate pharmacology, adverse effect, kinetics, and drug interactions.

Sucralfate is notorious for drug binding interactions and can reduce the concentrations of many drugs which I cover in the podcast.

Four times daily dosing is a big downside to sucralfate and why it isn’t used terribly often for GI issues like esophagitis.

The suspension formulation of sucralfate does contain some sugar so be aware of this in our diabetes patients.

Scopolamine Pharmacology

In this episode of the RLP podcast, I discuss scopolamine pharmacology.

Scopolamine patches can be used in the management of motion sickness and surgery/anesthesia induced nausea and vomiting.

Transdermal scopolamine has a slow onset of action so we need to be deliberate about the timing of placement (usually 4-6 hours prior to anticipated time of symptoms).

Transdermal scopolamine is highly anticholinergic and can cause dry eyes, dry mouth, urinary retention, and confusion.

Hyoscyamine Pharmacology

Hyoscyamine is an anticholinergic medication that is primarily used for GI problems like spasms and pain associated with IBS.

Because of the highly anticholinergic nature of hyoscyamine, it can cause dry eyes, dry mouth, urinary retention, and constipation.

Be aware of the risk for the prescribing cascade with hyoscyamine. Saliva substitutes for dry mouth, artificial tears for dry eyes, etc.

Sedation is a concern with hyoscyamine and this can be exacerbated by drugs like benzodiazepines, opioids, and older antihistamines.

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.
