149 - Replenishing the Missing Element: A Complete Review of Iron Deficiency Anemia Jun 14, 2022

Show notes

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 chronic kidney disease, cancer, upcoming surgery, etc. Available IV options are equally effective and selection of an agent depends on insurance coverage, formulary inclusion, patient preference for test dose, frequency of dosing, etc.

148 - Grit, Determination, and Entrepreneurship: A Pharmacist's Career Path to Starting an Independent Pharmacy May 24, 2022

Show notes

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.
Companies like "Health Mart" have a franchise-like model to provide products, services, documentation, policies and procedures, and more to independent pharmacies. These companies reduce the workload associated with running a pharmacy so that the pharmacy owners can focus their time and attention on the business itself and providing exceptional customer service.
There are a number of challenges to independent pharmacies – some of these challenges involve PBMs (DIR fees and MAC pricing) as well as unrestricted dispensaries in primary care clinics.

147 - Key Recommendations from the 2022 AHA/ACC/HFSA Heart Failure Guidelines May 03, 2022

Show notes

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 <= 40%), HFimpEF (with improved ejection fraction – was <=40% but is now > 40%), HFmrEF (ejection fraction 41% to 49% with increased LV filling pressures), and HFpEF (preserved 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 congestive symptoms in patients with heart failure; however, guidelines do not recommend a specific maximum intake nor does data support clinical outcome benefit with dietary sodium restriction.

146 - New Drugs for Bad Bugs: Six Newer Antibiotics for Multidrug Resistant Pathogens Apr 12, 2022

Show notes

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 (Klebsiella pneumoniae carbapenemase). Vaborbactam does not restore activity for meropenem-resistant Pseudomonas.
Imipenem/cilastatin/relebactam (Recarbrio®) has similar coverage to Avycaz® and Vabomere®; true niche in therapy is not yet well defined.
Cefiderocol (Fetroja®) uses a unique mechanism to enter gram negative bacteria and has a broad spectrum of activity against carbapenemase-producing bacteria and many other multidrug resistant gram negatives. It has no gram positive activity.
Eravacycline (Xerava®) is a tigecycline-like tetracycline with a broad spectrum of activity against carbapenemase-producing gram negative, gram positive, an anaerobic bacteria EXCEPT it lacks coverage for Pseudomonas.

145 - Advancing the Profession: Contraceptive Prescribing by Pharmacists in Illinois Mar 22, 2022

Show notes

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.

144 - mRNA Technologies and their Implications in Therapeutics: Q&A with Dr. Martin Mar 01, 2022

Show notes

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, influenza, Zika and CMV) as well as therapeutics for non-viral diseases (including a personalized cancer vaccine and a VEGF-A mRNA molecule for myocardial ischemia).

143 - The Low Down on Hypothyroidism: The Essentials of What Healthcare Providers Need to Know Feb 08, 2022

Show notes

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 compatible and can be interchanged by a pharmacist, patients should be maintained on the same formulation whenever possible.

142 - New Gains in Weight Loss Pharmacotherapy Jan 18, 2022

Show notes

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).

141 - What You Need to Know about Hepatorenal Syndrome: New Definitions, Treatments, and Clinical Pearls Dec 28, 2021

Show notes

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 not in the ICU, midodrine and octreotide are recommended. Therapy is continued until renal function recovers, if there is no improvement at 4 days, or if a full 14 days of therapy has been given.

140 - The Ultimate Guide to SSRIs: An In-Depth Drug Class Review Dec 07, 2021

Show notes

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.
