Helixtalk - Rosalind Franklin University's College Of Pharmacy Podcast

In this episode, we “deep dive” into diltiazem, describing its most important drug facts, pharmacology and medicinal chemistry, pharmaceutics, AB compatibility, and important medication safety issues. Key Concepts Diltiazem is a non-dihydropyridine calcium channel blocker (CCB). This type of CCB reduces both heart rate and blood pressure whereas dihydropyridine CCBs only reduce blood pressure. Diltiazem has numerous dosage forms (IV, immediate release tablets, and extended-release products). Extended-release products are always dosed once or twice daily. Historically there were a significant number of extended-release capsules with a variety of brand names and AB-compatibility. Today, only a few branded products still exist in the US market (Cardizem CD, Cartia XT, Cardizem LA, Tiazac, Taztia XT). The FDA Orange Book describes “AB” compatibility, which outlines whether one formulation is therapeutically equivalent to another formulation. Depending on state law, pharmacists can use AB compatibility codes to a

In this episode, the hosts of the HelixTalk reflect back on the history and making of HelixTalk to commemorate the 150th episode. We review each of our three favorite episodes and with a brief reflection on the episode content. We have come a long way from where we began and it is all thanks to the wonderful listeners and contributors who have a common thing in mind: a quest and thirst for knowledge!

In this episode, we will cover a complete overview of definition, diagnosis, treatment and monitoring of iron deficiency anemia (IDA). Key Concepts Iron-deficiency anemia (IDA) is the most common type of nutritional anemia. The most common risk factors are insufficient dietary intake, malabsorption, and increased requirement states like pregnancy or blood loss. Serum ferritin serves as the most confirmatory lab test for diagnosis of IDA. A low serum ferritin level usually indicates the presence of IDA. Other iron studies and CBC can be helpful in diagnosing IDA as well.  Generally oral iron therapy is a well-accessible, inexpensive, safe, and effective approach for IDA treatment. Almost all PO options are equally effective and safe. Gastrointestinal adverse effects are common and can sometimes limit further dosing.  Intravenous iron therapy is generally reserved for patients who are refractory or intolerant to PO treatment, have malabsorption of PO iron therapy, or have other health conditions such as chroni

In this episode, we interview Hetal Patel, PharmD and RFUMS COP Alumni, regarding her career path that eventually led her to open Lebanon Family Pharmacy in TN in 2021. We discuss the challenges and opportunities of starting a new independent pharmacy and what the future of independent pharmacy looks like. Key Concepts Starting a new, independent pharmacy requires substantial planning 8 to 12 months before the pharmacy’s doors even open. New pharmacy owners need to consider a variety of factors such as location, type of building, a business plan with financial analysis, a variety of building and pharmacy inspections, paperwork and government approvals, and so much more. PSAOs (pharmacy services administrative organizations) can be helpful, especially for new pharmacy owners, to serve as a liaison between the pharmacy and PBMs (pharmacy benefit managers) to negotiate reimbursement contracts. As owners gain more experience, there may be financial advantages to not using PSAOs and negotiating with PBMs directly

In this episode, we review new updates and key concepts from the 2022 AHA/ACC/HFSA Guideline for the Management of Heart Failure. This guideline is newly published (April 2022) and is a full update of the 2013 guidelines and the 2017 focused update for heart failure. Key Concepts Heart failure is classified as HFrEF (heart failure with reduced ejection fraction = 50% with increased LV filling pressures). Most drug therapy recommendations are similar for HFrEF, HFimpEF, and HFmrEF whereas HFpEF therapies are different. The 2022 AHA/ACC/HFSA heart failure guidelines now recommend SGLT2 inhibitors, such as dapagliflozin and empagliflozin, in patients with HFrEF, HFmrEF, and HFpEF. The 2022 AHA/ACC/HFSA heart failure guidelines continue to prefer ARNi, such as sacubitril/valsartan (Entresto), over ACE inhibitors and ARBs in patients with HFrEF. Based on the PARAGON-HF trial, ARNi is also recommended in those with HFpEF albeit with a weak recommendation. Avoiding excessive dietary sodium is reasonable to reduce c

In this episode, we discuss six newer antibiotics that target multidrug resistant gram negative bacteria with Dr. Christie Bertram, PharmD, BCIDP. We review common resistance mechanisms, particularly to carbapenems, and highlight the current role in therapy for the following antibiotics: ceftolozane/tazobactam (Zerbaxa®), ceftazidime/avibactam (Avycaz®), meropenem/vaborbactam (Vabomere®), imipenem/cilastatin/relebactam (Recarbrio®), cefiderocol (Fetroja®), and eravacycline (Xerava®). Key Concepts Ceftolozane/tazobactam (Zerbaxa®) is primarily used for multidrug resistant Pseudomonas; it does not cover carbapenemase-producing organisms and (despite the tazobactam) needs metronidazole for intra-abdominal anaerobic coverage. Ceftazidime/avibactam (Avycaz®) is primarily used to cover CRE (Carbapenem-resistant Enterobacterales) but also has activity for many other gram negatives except Acinetobacter. Meropenem/vaborbactam (Vabomere®) has similar coverage to Avycaz® but may provide coverage for certain KPCs (Klebs

In this episode, we bring in two guests to discuss the impact of professional advocacy and resulting professional advancements in the state of Illinois. These guests were the front-line agents of advocacy which resulted in pharmacists' ability to prescribe hormonal contraceptives for patients in Illinois (HB 135). We take a deep dive into their efforts to make this change possible, how it will impact patient care, and its implications on possibilities for further advancement of the pharmacy profession all the while highlighting the importance of professional advocacy.

In this episode, we interview Dr. Danyelle Martin, a Medical Science Liaison (MSL) at Moderna, in order to learn more about the what, how, and future of mRNA-based therapeutics, and what impact it can have on healthcare and healthcare professionals in general. Key Concepts Moderna has a “Research Engine” proprietary service that takes an mRNA idea from a web-based digital designer, to a digital ordering system, and finally to a production facility where mRNA constructs are synthesized and quality tested. Pharmaceutics play a big role in the formulation of mRNA particles. Lipid nanoparticles (LNPs) play an important role for stability and delivery of mRNA cargo. After LNPs and mRNA are co-formulated, the product is purified, filtered, frozen, and subjected to a series of good manufacturing practice (GMP) tests to ensure product quality. COVID-19 vaccines are a small glimpse into the potential future of mRNA-based therapeutics. Moderna’s pipeline includes mRNA vaccines for other viruses (including RSV, influen

In this episode, we review the diagnostic criteria and treatment strategy of hypothyroidism including the controversy surrounding brand versus generic levothyroxine and non-levothyroxine thyroid drugs. Key Concepts The most common cause of hypothyroidism is autoimmune thyroiditis - the body attacks the thyroid gland cells. Typically in hypothyroidism, TSH levels will be high and thyroid hormone levels (T3 and T4) will be normal or low. Levothyroxine is the drug of choice to treat hypothyroidism. Doses should start low (to avoid cardiovascular side effects) and then be titrated up based on TSH levels. All other thyroid hormone formulations (including Thyroid USP, Armour Thyroid, liothyronine, etc.) are NOT recommended for use in hypothyroidism. These are not FDA approved medications and there is no data showing these products are more effective than levothyroxine. Generic formulations of levothyroxine are as effective and safe as brand-name Synthroid®. Although several levothyroxine formulations are AB compat

In this episode, we will build up on our previous Weight loss Pharmacotherapy Episode, episode #13 to discuss updates in guidelines, prevention of obesity from comorbidity standpoint, and new treatment agents for weight-loss with a particular focus on Contrave (naltrexone/bupropion), Saxenda (liraglutide), and Wegovy (semaglutide).

In this episode, we provide a concise overview of the diagnosis and treatment of hepatorenal syndrome-acute kidney injury (HRS-AKI) with a focus on the new HRS-1 definition (now called HRS-AKI), new data with terlipressin, and the AASLD 2021 guidelines. Key Concepts At a basic level, HRS-AKI is caused by portal hypertension leading to systemic vasodilation and a prerenal state.  Our treatment focuses on increasing vascular volume (usually with albumin) and vasoconstriction to increase renal perfusion. The newest HRS-AKI definition borrows most of the AKI definitions from the KDIGO criteria for AKI.  HRS-AKI requires cirrhosis, ascites, AKI, and an exclusion of other etiologies of AKI. In AKI and HRS-AKI, concentrated (25%) albumin is given. A dose of 1 gm/kg/day (max 100 gm) for two days is used for AKI.  For HRS-AKI, a dose of 20-50 grams/day is recommended. The preferred vasoconstrictor in HRS-AKI is terlipressin; however, it is not available in the US. Norepinephrine (if in the ICU) is second-line.  If no

In this episode, we review the pharmacology, indications, adverse effects, and unique drug characteristics of the most common SSRIs on the market. Key Concepts SSRIs (selective serotonin reuptake inhibitors) are the drug of choice for depression, anxiety, and a variety of other psychiatric indications. Fluoxetine (Prozac) and paroxetine (Paxil) inhibit CYP2D6, a metabolic pathway for several opioid analgesics, tamoxifen, and many other antidepressants. Adverse effects of SSRIs start immediately but the beneficial psychiatric effects take up to 1 to 2 months to occur. Patient counseling about the timing of adverse effects and efficacy are important! SSRIs should not be abruptly discontinued in patients taking the medication chronically. Withdrawal symptoms can include flu-like symptoms, changes in mood or sleep, and (rarely) even electric-like shocks. To discontinue, the SSRI dose should be tapered down over the period of several weeks.

In this episode, we discuss the recent accelerated approval of the new monoclonal antibody-based treatment agent, aducanumab (Aduhelm), by the FDA. We dive into the drug approval process, the efficacy and safety data, and the behind-the-scenes story of the FDA approval. Furthermore, we will present the controversy behind the approval and what it means for stakeholders. Key Concepts Aducanumab (Aduhelm) is a monoclonal antibody proven to reduce beta amyloid plaques in patients with Alzheimer’s disease. Despite reducing plaques, aducanumab did NOT result in meaningful cognitive improvements in patients receiving the drugs versus placebo; additionally, the drug was associated with a potentially concerning adverse effect called ARIA-E (amyloid related imaging abnormalities-edema). Despite an advisory panel unanimously recommending AGAINST approval and a lack of clinical outcome improvement, the FDA did go on to approve the drug in patients with Alzheimer’s disease using an accelerated approval process. In the ep

In this episode, we discuss the fascinating science of pharmaceutics with Dr. Kristen Ahlschwede and Dr. Rahul Deshmukh. We explore how dosage forms and excipients play an important role in how a drug product behaves in the human body with a particular focus on fentanyl patches, osmotic tablets (with laser-drilled holes), Depakote Sprinkles, and IV amiodarone. Key Concepts Fentanyl patches were reformulated from a drug-in-a-reservoir system to an adhesive matrix system to prevent abuse and misuse. The new formulation prevents fentanyl from "leaking" out when cut. Osmotic tablet systems, such as Procardia XL, Glucotrol XL, and Concerta, use an "active" layer (containing drug) adjacent to a "push" layer that is osmotically active. When the push layer is exposed to water in the GI tract, it swells and pushes the active layer through a small laser-drilled precision hole. "Sprinkle" dosage forms typically involve small pellets inside a capsule, such as Depakote Sprinkles. The capsule itself does not delay or exte

In this episode, we reveal what goes on behind the scenes for drug pricing and pharmacy reimbursement with Dr. Benjamin Jolley. Our discussion covers important concepts like PBMs, DIR fees, MAC pricing, and even possible upcoming changes at the federal government. Key Concepts Prescription drug reimbursement is a major factor in the decline of independent pharmacies nationwide. Complex reimbursement models, fees, and drug pricing structures are frequently not well understood by both patients and many healthcare providers. A pharmacy benefits manager (PBM) is a company hired by an insurance company to handle prescription drug coverage and reimbursement. Three PBMs control more than three-quarters of the entire US market and can often dictate the terms of a drug reimbursement contract with pharmacies. PBMs determine how much they will pay for the cost of a medication using either a benchmark (such as the average wholesale price minus some percentage) or a list of the maximum allowable cost (MAC) maintained by

In this episode, we discuss the recently published major updates in the 9th edition of the anticoagulation guidelines from CHEST. These new recommendations range from initiation of therapy, secondary prevention, and management of post-thrombotic syndrome. Key Concepts Among patients with cancer-associated VTE, DOACs are preferred over low molecular weight heparins (LMWH) EXCEPT in patients with GI cancers. The preferred anticoagulant in those with GI cancers is either LMWH or apixaban. Among patients with antiphospholipid antibody syndrome, warfarin (INR goal 2-3) is preferred over DOAC therapy. In the extended phase of treatment (secondary prevention after 3 months of treatment), lower anticoagulant doses should be used (such as apixaban 2.5 mg BID or rivaroxaban 10 mg daily). In patients with a DVT, IVC filters should only be used when anticoagulation therapy is contraindicated. IVC filters reduce the risk of PE but do not alter the risk of DVT extension or future DVTs. Compression stockings are not recomm

In this episode, we debunk four medication myths that have persisted for decades: metronidazole and alcohol; statins and hepatotoxicity; cidal vs. static antibiotics; and "sulfa" allergies. Key concepts Metronidazole does not interact with alcohol (ethanol) and does not cause a disulfiram-like reaction. Statins can cause transient increases in liver function tests; however, these increases are not associated with hepatotoxicity. Routine LFT monitoring is not recommended unless clinically indicated signs or symptoms of liver injury exist. The distinction of bactericidal versus bacteriostatic antibiotics is irrelevant. No evidence exists showing that having a bactericidal drug has superior efficacy to a bacteriostatic drug. A “sulfa” allergy nearly always means an allergy to Bactrim (sulfamethoxazole-trimethoprim). There are many non-antibiotic sulfonamide-containing medications that do not need to be avoided in patients with a sulfa allergy; however, patients with an allergy to any medication have an increase

In this episode, we provide a concise review of the diagnostic criteria and general treatment approach to patients with hypertensive emergencies. Key Concepts Hypertensive “urgency” is a misnomer - patients do not require immediate therapy and definitely should not receive IV therapy. In most cases, the goal blood pressure in hypertensive emergencies is to decrease by no more than 25% in the first hour, achieve a BP of 160/100 in hours 2-6, then over the next 24-48 hours lower to a more normal blood pressure goal. Labetalol is the preferred IV push antihypertensive UNLESS patients have acute heart failure, bradycardia, or possibly in patients with asthma/COPD. Nicardipine is one of the most commonly used IV infusions for hypertensive emergencies. Most other continuous infusions are reserved for special types of hypertensive emergencies (e.g. nitroglycerin for pulmonary edema or acute MI, esmolol for aortic dissection).

In this episode, we will explore depths of COVID 19 vaccine hesitancy - what it is, how to identify and address it, and some helpful resources. Key Concepts When a patient seems hesitant to consider the COVID-19 vaccine, explore their hesitations further with a simple “why” or “tell more more” question. Understand the root of hesitancy and provide personalized responses using motivational interviewing. Key concepts of motivational interviewing include asking open-ending questions, asking the patient to share their concerns, reflective listening, acknowledging without judgement, and asking for permission to share information. The goal of a vaccine hesitancy conversation is not necessarily to have the patient receive the vaccine today; the goal is to move the patient one step closer to validated facts (combating misinformation) and consideration of receiving the vaccine.

In this episode, we will explore the history of COVID vaccine development and have a heart-to-heart conversation with Dr. Archana Chatterjee regarding her role as a dean of the RFUMS Chicago Medical School, her career path, and her position and functions on the FDA’s Vaccines and Related Biological Products Advisory Committee (VRBPAC).
