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...

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...

On this podcast episode, I cover risedronate pharmacology, adverse effects, drug interactions, and much more. There is a strict administration procedure with risedronate which is designed to reduce adverse effects and enhance absorption. I discuss this in the podcast. Many medications may cause osteoporosis and may precipitate treatment with risedronate. Corticosteroids and excessive thyroid hormone replacement are two examples. Patients should remain upright (sitting...

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...

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...

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.

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...

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...

Darifenacin's pharmacology is selective for the Muscarinic-3...

In this podcast episode, I discuss naltrexone pharmacology, adverse effects, drug interactions, and much more. Naltrexone is an opioid antagonist and can blunt the effects of opioid agonists. Because of this, the medication can be used to manage opioid use disorder. Hepatotoxicity is a concern of naltrexone and because of this, it is recommended to monitor LFTs. There is an injectable, long-acting formulation of naltrexone that can be used for opioid and alcohol use...

On this podcast episode, I discuss acamprosate pharmacology, adverse effects, drug interactions, and much more! Acamprosate's most common adverse effect is diarrhea. It is a primary reason why patients will ask to stop taking this medication. It is critical to assess renal function prior to using acamprosate. Dose adjustments are recommended when patients have a CrCl of less than 50 ml/min. Unlike naltrexone, acamprosate avoids liver metabolism making it an alternative...

On this podcast episode, I discuss alfuzosin pharmacology, adverse effects, drug interactions, and much more! Alfuzosin is an alpha blocker used to help relieve the symptoms of BPH. Low blood pressure is a possible adverse effect of alfuzosin and is more likely when combined with PDE-5 inhibitors like sildenafil. CYP3A4 is an important enzyme in the metabolism of alfuzosin. Inhibitors of CYP3A4 can raise concentrations and increase the chance of alfuzosin toxicity.
