Objective: The purpose of this article is to review the available clinical trial data for andexanet alfa and its role in clinical practice. Data Sources: A MEDLINE/PubMed search was conducted (January 2000 to January 2019) using the keyword andexanet alfa for clinical trials. References of identified articles were searched by hand for additional citations. ⋯ Relevance to Patient Care and Clinical Practice: With the approval of this reversal agent, patients and providers can feel safer when using apixaban and rivaroxaban, which in turn may increase the use of these anticoagulant agents. Conclusions: The new FDA approval of andexanet alfa will allow safer use of oral anticoagulants and will likely further the use of direct oral anticoagulants for anticoagulant needs. Reversing enoxaparin-/edoxaban-induced bleeding with this agent should be limited because there is no FDA approval owing to the fact that only phase II trial data available.

Objective: To review the pharmacology, efficacy, and safety of the calcitonin gene-related peptide (CGRP) inhibitor erenumab for migraine preventive therapy. Data Sources: A MEDLINE/PubMed search (January 2000 to January 2019) was conducted using the keywords erenumab-aooe, erenumab, migraine, migraine prophylaxis, migraine prevention, and chronic migraine. Additional articles were identified by hand from references. ⋯ Conclusion: Erenumab is an effective once-monthly injectable agent for migraine prevention in patients with chronic or episodic migraine. It is also effective for patients who have previously failed migraine preventive therapy. Erenumab has a favorable adverse effect profile, which may improve patient adherence.
