Objective: To review the safety and efficacy of brexanolone for the treatment of moderate to severe postpartum depression (PPD). Data Sources: A literature search through PubMed was conducted (January 2012 to July 2019) using the keyword brexanolone for clinical trials published in the English language. Study Selection and Data Extraction: Articles were selected if they were related to the Food and Drug Administration (FDA) approval of brexanolone or provided novel clinical information regarding this drug entity. Data Synthesis: The findings of the review show that brexanolone administered via IV infusion is both an effective and a fairly safe option for the treatment of PPD. Relevance to Patient Care and Clinical Practice: There are several antidepressants currently used to treat PPD; however, this is the first with FDA approval for this indication. The rapid onset of action of brexanolone may offer a quicker relief of these symptoms and may possibly lead to improved quality of life for both the mother and the child. Conclusion and Relevance: The recent FDA approval of brexanolone may offer an effective treatment of moderate to severe PPD and has been shown to rapidly decrease depression symptoms.
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. Study Selection and Data Extraction: We included English-language articles (excluding poster presentations) evaluating erenumab pharmacology, efficacy, or safety in humans for migraine prevention. Data Synthesis: Erenumab is a CGRP inhibitor that inhibits vasodilation in response to acute migraines, which decreases pain perception during the migraine. Erenumab efficacy and safety has only been compared with placebo, but its reduction in monthly migraine days (MMDs) and medication response (≥50% reduction in MMDs) are comparable to current recommended off-label therapies for migraine prevention in short-term treatment studies. Additionally, erenumab is associated with low adverse event burden with no difference found compared with placebo per published clinical trials. Relevance to Patient Care and Clinical Practice: Erenumab is the first medication approved in the United States for the prevention of migraines in adults. No head-to-head data are available, but existing data suggest that erenumab is at least as effective as current off-label products and with reduced adverse effects. 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
