What is erenumab?
Erenumab (full biological name: erenumab-aooe) is a once-monthly, injectable medication that can be self-administered subcutaneously (under the skin) for the prevention of migraine in adults.
Erenumab works by blocking the effect of calcitonin gene-related peptide (CGRP) which is a small protein that is highly prevalent in the sensory nerves that supply the head and the neck. CGRP is involved in pain transmission and levels increase during a migraine attack. It may also play a causative role in the formation of migraine attacks. CGRP inhibitors are used to manage migraines and there are two types of CGRP inhibitors; monoclonal antibodies and CGRP receptor antagonists (gepants). Erenumab is a monoclonal antibody.
Erenumab was first FDA-approved on May 17, 2018, under the name Aimovig.
The erenumab brand name is Aimovig.
