The cardio-selective beta-blockers include atenolol, betaxolol, bisoprolol, esmolol, acebutolol, metoprolol, and nebivolol. This activity outlines the indications, mechanisms of action, methods of administration, important adverse effects, contraindications, and monitoring, of selective beta-1 antagonists, so providers can direct patient therapy in treating indicated disorders as part of the interprofessional team, with a basis on the current knowledge for optimal utilization. Treatment with beta-1 blockers reduces the risk of stroke, coronary artery disease, and congestive heart failure. Their use is associated with decreased morbidity and mortality post-myocardial infarction. Non-FDA-approved uses include migraine prophylaxis, treatment of arrhythmias, tremor reduction, and the symptomatic treatment of anxiety disorders. FDA-approved uses of beta-1-selective blockers include hypertension, chronic stable angina, heart failure, post-myocardial infarction, and decreased left ventricular function after a recent myocardial infarction.

The Hospital Pharmacy Academy is my online membership site that teaches pharmacists practical critical care and hospital pharmacy skills you can apply at the bedside so that you can become confident in your ability to save lives and improve patient outcomes. This is in addition to hundreds of other resources to help in your practice. Members of my Hospital Pharmacy Academy have access to practical training on the use of high-dose insulin therapy, as well as clinical pearls related to using glucagon, all from a pharmacist’s point of view. This therapy is growing in popularity as it has demonstrated consistent effects and is feasible to implement.Ĭlinicians should note that there is not a corresponding expert guideline for beta-blocker overdose, and although high-dose insulin therapy is effective for this indication as well, many publications still recommend giving glucagon for beta-blocker overdoses. The more effective intervention that the guideline authors are referring to is high-dose insulin therapy. Vomiting and hyperglycemia have been reported in several case reports, and more effective interventions for the treatment of CCB poisoning are available.

The workgroup suggests not to use glucagon because case series reported variable effects. The only mention of glucagon occurs in the appendix for the guidelines where the authors give the following explanation: These effects occur because glucagon directly increases cyclic AMP. Glucagon is often referenced as a possible treatment for calcium channel blocker overdose because it can cause increases in heart rate, blood pressure, and cardiac contractility, without regard to calcium channels being blocked. However noticeably absent from these guidelines is any mention of glucagon in the main article. The guideline authors make additional recommendations for cardiogenic shock, refractory patients, and peri-arrest patients including dobutamine, atropin, lipid emulsion, pacemaker therapy, and VA-ECMO. These guidelines list the following first line therapies prioritized based on desired effect: Subscribe on iTunes, Android, or StitcherĬritical Care Medicine has published in 2017 Experts Consensus Recommendations for the Management of Calcium Channel Blocker Poisoning in Adults.
