Drug Group

CGRP receptor antagonist (migraine treatment)

Commonly Used For

This medication is used to:

• Treat acute migraine attacks.
• Manage migraine with or without aura.
• Reduce migraine-associated symptoms.

Key Characteristics

• Form: Oral tablets (50 mg, 100 mg) (detailed in Dosage section).

• Approval: FDA-approved (2019 for Ubrelvy) and EMA-approved for acute migraine treatment.

3. Indications and Uses of Ubrogepant

Ubrogepant is indicated for migraine relief, targeting the underlying pathophysiology of the condition:

• Acute Migraine with or without Aura: Treats acute migraine attacks in adults, providing pain relief within 2 hours, supported by clinical trials like ACHIEVE I and II, per American Headache Society guidelines.
• Cluster Headache: Investigated off-label for episodic cluster headache, reducing attack frequency, with emerging data from neurology research.
• Chronic Migraine Prevention: Explored off-label as an adjunct to preventive therapies (e.g., topiramate), decreasing monthly migraine days, supported by headache specialist studies.
• Post-Traumatic Headache: Used off-label to manage persistent post-traumatic headaches following concussion, improving quality of life, with evidence from trauma neurology.
• Menstrual Migraine: Employed off-label to address hormonally triggered migraines, enhancing symptom control during menstruation, per gynecologic neurology data.
• Medication Overuse Headache (MOH): Investigated off-label to break the cycle of MOH in chronic migraineurs, reducing dependency on acute treatments, supported by headache management research.
• Pediatric Migraine: Explored off-label in adolescents (12–17 years) with migraines, adjusting doses for safety, with preliminary pediatric neurology findings.
• Migraine with Comorbid Depression: Used off-label to manage migraines in patients with depression, improving both conditions, with psychiatric-neurology crossover studies.
• Tension-Type Headache: Investigated off-label for tension-type headaches with migrainous features, offering relief, with data from pain management trials.

Note: This drug is for acute use only; consult a healthcare provider for chronic migraine management or off-label applications.

4. Dosage of Ubrogepant

Important Note: The dosage of this CGRP receptor antagonist must be prescribed by a healthcare provider. Dosing varies by migraine severity and patient response, with adjustments based on clinical evaluation.

Dosage for Adults

• Acute Migraine:
  • Initial: 50 mg or 100 mg as a single dose at migraine onset.
  • Second Dose: May take another 50 mg or 100 mg after 2 hours if needed, maximum 200 mg/day.

  • 50 mg as initial dose; avoid if severe (Child-Pugh C).

Dosage for Children

• Adolescents (12–17 years, off-label):
  • 50 mg at onset, titrated to 100 mg if tolerated, under pediatric neurologist supervision.
  • Not recommended under 12 years.

Dosage for Pregnant Women

• Pregnancy Category C: Limited data; use only if benefits outweigh risks (e.g., severe migraines). Consult an obstetrician, with fetal monitoring.

Dosage Adjustments

• Renal Impairment: No adjustment needed for mild to moderate (CrCl 30–89 mL/min); avoid if severe (CrCl <30 mL/min) or on dialysis.
• Hepatic Impairment:
  • Mild (Child-Pugh A): No adjustment; moderate (Child-Pugh B): 50 mg maximum; severe (Child-Pugh C): Avoid.
• Elderly: Start with 50 mg; increase to 100 mg if tolerated, with monitoring.
