Fluticasone (Flonase) is a nasal corticosteroid that is used in the management of allergic rhinitis. A primary adverse effect that I have seen in practice with fluticasone is the risk for nose bleeds. Flonase can have some interactions via CYP3A4. Inhibitors of CYP3A4 like clarithromycin can increase concentrations. While the risk for systemic exposure is low with nasal fluticasone, long-term, high dose, and frequent use should be monitored appropriately. Be sure to check out our free Top 20...

On this episode, I discuss (Carafate) sucralfate pharmacology, adverse effect, kinetics, and drug interactions. Sucralfate is notorious for drug binding interactions and can reduce the concentrations of many drugs which I cover in the podcast. Four times daily dosing is a big downside to sucralfate and why it isn’t used terribly often for GI issues like esophagitis. The suspension formulation of sucralfate does contain some sugar so be aware of this in our diabetes patients. Be sure to check...

On this episode, I discuss atenolol pharmacology, adverse effects, pharmacokinetics, and drug interactions. Atenolol is primarily cleared by the kidney which should tell you that we need to pay attention to dose adjustments as renal function declines. Atenolol is a beta-1 selective agent that is NOT a preferred beta-blocker in HFrEF. Pulse and blood pressure monitoring is essential with any beta-blocker like atenolol.
