CGRP antagonists effectively reduce monthly headache days in chronic migraine with medication overuse headache


Key clinical point: Monoclonal antibodies inhibiting calcitonin gene-related peptide (CGRP) effectively reduced monthly headache days, symptomatic drug consumption, and headache severity consistently over 12 months in patients with chronic migraine complicated by medication overuse headache (MOH).

Major finding: Overall, 80% of patients showed both ≥50% reduction in monthly headache days and ≥50% reduction in analgesics intake at the 3-month follow-up visit and 78.8% continued to show the improvements at the 6-month follow-up visit. The mean Migraine Impact and Disability Assessment Scale score decreased from 56.5 (range 27-63) at baseline to 13.1 (range 11-37) at 9 months, with 71% of patients being responders even at 1 year.

Study details: The data come from a prospective study of 303 patients with chronic migraine complicated by MOH who received CGRP antagonists for at least 6 months up to 1 year.

Disclosures: No source of funding was declared. The authors declared no competing interests.
