Vonoprazan Pharmacology – New Esophagitis Medication Class! Episode 326

5/9/2024
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.

Antihypertensive Drug Interactions Podcast – Episode 316

2/29/2024
On this podcast episode, I discuss some of the most common antihypertensive drug interactions you need to know. One major interaction I discuss is the trifecta of a diuretic, an ACE or ARB, and an NSAID. This combination significantly increases the risk for acute renal failure. Nitrates aren't classically referred to as an antihypertensive but they can definitely cause some problems when combined with PDE5 Inhibitors. Lithium can interact with 3 blood pressure medication classes. ACEIs, ARBs, and diuretics can all increase the risk for lithium toxicity.

Teplizumab For Diabetes Episode 315 – Real Life Pharmacology Podcast

2/22/2024
Teplizumab is a relatively new agent that helps delay the progression of type 1 diabetes. It slows the rate of beta-cell destruction in the pancreas. Teplizumab is associated with cytokine release syndrome which can result in flu-like symptoms of fever, aches, and headache. Cytokine release syndrome due to teplizumab can be reduced by using appropriate pretreatment medications. Those medications can include analgesics, antihistamines, and/or antiemetics. Teplizumab is associated with suppressing the immune system so it is ideal to get vaccinations completed before using this medication. I go over the specific recommendations in the podcast episode.

Captopril Pharmacology Podcast – Episode 314

2/15/2024
On this podcast episode, I discuss captopril pharmacology, kinetics, interactions, and much more! Captopril is an ACE Inhibitor. It can cause hyperkalemia, cough, and renal impairment. One of the notable issues with captopril is its relatively short half-life which requires it to be dose frequently throughout the day. Lithium is an important drug interaction and the use of captopril with this medication may increase concentrations and the chance for toxicity.

Mechanisms of Drug Interactions Episode 313

2/8/2024
On this episode of the Real Life Pharmacology podcast, I take a dive into the most common mechanisms of drug interactions. Below I list some of the common drug interactions seen in practice and how they work! Opposing Effects Many drugs will work on various receptors throughout the body. To use as an educational point, there is no better example to point to than the beta receptor. Beta-blockers are frequently used in clinical practice for their ability to lower blood pressure and slow the heart rate. Both of these beneficial actions are primarily achieved by blocking the effects of beta-1 receptors. Some beta-blockers have action on alternative beta receptors. Propranolol is one such beta-blocker that is classified as a non-selective beta-blockers. This means that in addition to the positive effects on beta-1 receptors, it can also have blocking effects on beta-2 receptors. The blockade of the beta-2 receptor by propranolol can also be life-changing. It can directly oppose beta-2 agonists like albuterol from having their beneficial effects of opening up the airway. Enzyme Inhibition Medication metabolism is arguably the largest and most clinically significant source for drug interactions. Medications that are primarily metabolized by enzymes in the liver can be greatly affected if we affect how those enzymes work. CYP3A4 is one of the most well studied and well-known enzymes that can impact hundreds to maybe even thousands of drugs. Apixaban is an oral anticoagulant that is broken down at least in part by CYP3A4. By using a CYP3A4 inhibitor like erythromycin, there is the potential to raise concentrations of apixaban. This could lead to a higher risk of bleeding. Enzyme Induction Carbamazepine is a drug that you must know. This drug is a potent enzyme inducer. This differs significantly from an enzyme inhibitor and will have the exact opposite clinical effect. Drugs that are inactivated by liver enzymes will be inactivated more quickly in a patient taking an enzyme inducer. Going back to our prior apixaban example above, carbamazepine can induce CYP3A4 and facilitate a more efficient and swifter breakdown of the drug. Bleeding will be less likely. The risk for treatment failure, usually in the form of a blot clot, will be more likely. Here’s more information from the past on carbamazepine. Alteration in Absorption Binding interactions can be consequential and are one of the most common types of drug interactions. Many medications have the potential to bind one another in the gut. This can lead to lower concentrations of a specific medication. Calcium and iron are two of the most common examples of medications that can bind other drugs. Alteration in Protein Binding By remembering that unbound drug is an active drug, you should appreciate the risk for protein binding alterations. A significant number of medications can bind proteins in the bloodstream. As this occurs, that drug is not freely available to create physiologic effects. When another medication is added that can also bind these proteins, this can displace other medications and increase the quantity of free drug in the bloodstream. This essentially allows for enhanced physiologic effects. Warfarin is a medication that is highly protein-bound. When another drug is added that can kick warfarin off of those protein binding sites, it can free up warfarin which will increase the likelihood of elevating the patient’s INR and increase their bleed risk. Alteration in Renal Elimination Some drugs can alter the way other medications are eliminated through the kidney. Chlorthalidone, like all thiazide diuretics, has the potential to block the excretion of lithium from the kidney. This can lead to lithium toxicity. This type of interaction, while significant, is much less common than drug interactions involve the liver and CYP enzyme pathways. Effects on Transporters One of the last types of drug interactions is the effe...

Insulin Aspart (Novolog) Pharmacology Podcast Episode 312

2/1/2024
On this podcast episode, I discuss insulin aspart pharmacology, adverse effects, drug interactions, and much more. Insulin apart is a rapid acting insulin product meant to bring down blood sugars quickly (most often after meals). It is important to remember a couple of medications that may counteract the effects of insulin and apart and raise blood sugar. I talk about corticosteroids and thiazide diuretics in the drug interaction section. Fiasp is a slightly modified insulin aspart molecule that allows for quicker absorption. This quicker absorption will allow for blood sugars to come down sooner than the Novolog formulation.
