Captopril Pharmacology Podcast – Episode 314

On this episode of the Real Life Pharmacology Podcast, I cover some of the most common food and supplement drug interactions. The 3 G's can potentially increase the risk of bleeding in patients on anticoagulants and antiplatelets. I discuss what supplements these are. There are some vitamins that can cause drug interactions. Vitamin C is a supplement that can alter the absorption of some medications. Metal cations like iron can bind certain medications and reduce absorption. I discuss which medications are most likely to be affected.

On this episode, I discuss the new medication vonoprazan and where it will likely be used in practice. Vonoprazan is from a brand new class of medication called "PCAB". I discuss this medication and its pharmacology in this podcast episode. Drug interactions and cost are the two major downsides of this medication that will likely limit its use compared to the PPIs. CYP3A4 inducers like rifampin, carbamazepine, and phenytoin should not be used with vonoprazan. They will reduce the effectiveness of vonoprazan.

Thou shalt identify limits for medications not intended for chronic use as well as not continue a medication indefinitely for symptoms that have an expected short duration 7. Thou shalt not start a medication from a similar medication class without appropriate rationale 8. Thou shalt not initiate a medication without considering medications that may treat duplicate conditions – Kill two birds with one stone 9. Thou shalt consider eliminating or reducing medications at every medication review 10. Thou shalt be willing to accept risk in discontinuing a medication if they were willing to accept the risk of initiating a medication

Thou shalt not start, ask for, dispense, or administer medication without reviewing a medication list that is accurate, up to date, and complete with over-the-counter medications and supplements 2. Thou shalt consider utilizing non-drug approaches and interventions to solve patient problems before initiating medication 3. Thou shalt assess if a medication is effective before adding a new medication for the same condition 4. Thou shalt consider any new symptom is an adverse effect of another medication until proved otherwise 5. Thou shalt not start a medication without an appropriate indication and assessing appropriate lab work

Warfarin concentrations can substantially be elevated by drugs that inhibit CYP2C9. I cover a few of them in my top 10 anticoagulant drug interactions.

Use the discount code: RLPPOD In this podcast episode, I discuss how to navigate SSRI drug interactions and identify some of the most common medications that have additive serotonergic activity. SSRIs have antiplatelet activity. I discuss how to navigate using other medications that may increase bleed risk in combination with SSRIs. Paroxetine and fluoxetine inhibit CYP2D6 I discuss how this can affect the benefits of tamoxifen therapy. Fluvoxamine is a nasty medication with regard to the number of and significance of drug interactions. I outline important fluvoxamine interactions in this podcast episode.

On this episode, I discuss travoprost pharmacology, adverse effects, administration, and much more on this podcast episode. Travoprost is used to reduce intraocular pressure in the management of glaucoma. I discuss the mechanism of action and adverse effects. Travoprost is a prostaglandin analog that can help reduce intraocular pressure and reduce the risk of the potential complication of blindness. Growth of eyelashes is a unique adverse effect associated with travoprost.

On this podcast episode, I finish up my breakdown of the Beers Criteria. I cover the use of sliding-scale insulin and sulfonylureas in geriatric patients. Hypoglycemia is a major concern with both of these diabetes management strategies. PPIs show up on the Beers criteria list as they can increase the risk of C. diff, pneumonia, fractures, and GI malignancies. Metoclopramide has dopamine antagonist activity and can increase the risk of EPS and tardive dyskinesia.

In this podcast episode, I break down some of the most common medications that show up on the Beers criteria list. I discuss cardiovascular medications in this podcast episode, including rivaroxaban and warfarin, and why they show up on the Beers list. Alpha-blockers who up on the Beers list as these medications are inappropriate to use for the management of hypertension. The Beers criteria addresses the use of aspirin in primary prevention. I break down what the criteria state and why it should be avoided in general.

On this episode, I discuss the pharmacology surrounding QTc prolongation and drug interactions. I discuss which medications are more likely to cause QTc prolongation and which patient populations we should be more concerned about. Antiarrhythmics are a common class of medication that can exacerbate QTc prolongation when used with other interacting medications. 500 ms is a common value utilized to help identify patients at risk for QTc prolongation and ultimately torsades de pointes.
