  • Itraconazole Pharmacology

    Itraconazole Pharmacology
    Aug 7 2025
    In this episode, we break down itraconazole—a potent antifungal with a lot of baggage. If you’re a pharmacist, clinician, or student who needs to understand how this drug works and why it can be tricky to use, this episode is for you. We start with the basics. Itraconazole blocks 14α-demethylase, an enzyme fungi need to make their cell membranes. That disruption kills or slows the fungus. It works against tough bugs like Aspergillus, Histoplasma, and Blastomyces, plus common skin infections. Side effects? Nausea, liver enzyme elevations, and more seriously, heart failure. Yes, itraconazole has a black box warning for worsening or causing congestive heart failure. If your patient has heart issues, think twice. Drug interactions are everywhere. Itraconazole is a strong CYP3A4 inhibitor. It can raise levels of drugs like statins, benzos, calcium channel blockers, and immunosuppressants—sometimes to dangerous levels. Don’t co-prescribe without checking.

  • Levomilnacipran Pharmacology

    Levomilnacipran Pharmacology
    Jul 31 2025
    In this episode of our pharmacology podcast, we take a deep dive into the pharmacology of levomilnacipran (Fetzima), a unique serotonin-norepinephrine reuptake inhibitor (SNRI) approved for the treatment of major depressive disorder (MDD) in adults. Designed for pharmacy students, clinicians, and anyone interested in psychopharmacology, this episode breaks down what makes levomilnacipran different from other antidepressants and how to use it effectively in clinical practice. We explore levomilnacipran's mechanism of action, which features a greater affinity for norepinephrine reuptake inhibition compared to serotonin—an uncommon trait among SNRIs. This pharmacologic profile gives it a distinctive effect on energy, motivation, and physical symptoms of depression. Listeners will also learn about its pharmacokinetics, including once-daily dosing, renal elimination, and metabolism via the CYP3A4 pathway—making drug interactions an important consideration. The episode also covers levomilnacipran side effects, including common adverse reactions like nausea, dry mouth, constipation, and increased heart rate or blood pressure. We'll also highlight rare but serious risks like serotonin syndrome and urinary hesitation. Because levomilnacipran drug interactions can impact safety and efficacy, we review important combinations to avoid, such as CYP3A4 inhibitors (e.g., ketoconazole), serotonergic drugs, and blood pressure-altering agents. For pharmacists and prescribers, this is a key segment to help guide safer medication use and monitoring. Finally, we wrap up with clinical pearls for starting, titrating, and monitoring levomilnacipran therapy—including renal dose adjustments and differences with duloxetine. Whether you're studying for boards or optimizing your patient’s antidepressant regimen, this episode delivers a concise, evidence-based overview of levomilnacipran pharmacology in a digestible, podcast-friendly format.

  • Asenapine Pharmacology

    Asenapine Pharmacology
    Jul 24 2025
    Asenapine is an atypical antipsychotic that acts as an antagonist at multiple receptors, including dopamine D2 and serotonin 5-HT2A, contributing to its antipsychotic and mood-stabilizing effects. Adverse effects of asenapine include somnolence, dizziness, and extrapyramidal symptoms. Because asenapine is significantly metabolized by CYP1A2, inhibitors or inducers of these enzymes can affect its plasma concentrations. Co-administration with other CNS depressants may increase the risk of sedation and impaired cognitive or motor function. Asenapine can prolong the QT interval, so caution is advised when used with other medications that affect cardiac conduction.
