Qulipta

Qulipta

Generic Name

Qulipta

Mechanism

Qulipta (ubrogepant) is a calcitonin gene‑related peptide (CGRP) receptor antagonist.
• It selectively blocks the CGRP receptor on trigeminal neurons and vascular smooth muscle, preventing CGRP‑mediated vasodilation and nociceptive transmission.
• Unlike triptans, it does not induce vasoconstriction of non‑brain vessels, reducing cardiovascular risk in migraineurs.

Pharmacokinetics

  • Absorption: Rapid oral absorption; peak plasma concentration (Cmax) at ~3 h (Tmax).
  • Bioavailability: ~31 % (dose‑dependent, 2–10 mg).
  • Distribution: Plasma protein binding ~96 %.
  • Metabolism: Primarily hepatic via CYP3A; minor CYP2D6 contribution.
  • Elimination: 80 % excreted unchanged in bile/intestinal tract; 20 % renal (no dose adjustment needed in mild–moderate CKD).
  • Half‑life: ~3 h (steady‑state reached after ~1 day).
  • Drug interactions:
  • Strong CYP3A inhibitors (e.g., ketoconazole) ↑ ubrogepant exposure (contraindicated).
  • Strong CYP3A inducers (e.g., rifampin) ↓ exposure (may necessitate higher dose, not recommended).
  • No clinically relevant interaction with triptans or NSAIDs.

Indications

  • Episodic migraine (with or without aura) in adults, *≥15 days/month* in prior 3 months.
  • Status migrainosus (persistent migraine ≥72 h) in adults, *in combination with oral/IV NSAIDs or triptans*.

Contraindications

  • Known hypersensitivity to ubrogepant or any component.
  • Severe hepatic impairment (Child‑Pugh C).
  • Pregnancy: Category B; avoid unless benefits outweigh risks.
  • Cardiovascular disease: While lower CV risk than triptans, counsel patients with known coronary artery disease or uncontrolled hypertension regarding potential mild elevation in blood pressure.
  • Use with strong CYP3A inhibitors or inducers: Not recommended.

Warnings
Angioedema: Rare but potentially life‑threatening.
Abdominal pain: Monitor if concurrent NSAID use.
Drug‑safety monitoring: Not required for routine therapy, but monitor vitals during first few doses in patients with CV risk.

Dosing

  • Standard dose: 10 mg orally once daily (maximum *1 dose/day*).
  • If inadequate response after 3 days: add 5 mg once daily (reduce 10 mg dose).
  • Route: Oral tablets.
  • Timing: Take with or without food; food may delay absorption slightly.
  • Missed dose: Take as soon as remembered; do not double‑dose.

Adverse Effects

Common (≥10 %)
• Nausea
• Constipation
• Dizziness
• Fatigue
• Upper respiratory infection

Serious (≤1 %)
• Hypotension (orthostatic)
• Angioedema
• Severe abdominal pain
• Acute pancreatitis (rare)

Monitoring

  • Baseline: Vital signs, kidney function (eGFR), liver enzymes.
  • During therapy:
  • Cardiac status in high‑risk patients (BP, heart rate).
  • Watch for signs of angioedema.
  • LFTs if prolonged daily use >3 months.
  • Follow‑up: Re‑evaluate migraine frequency after 3 months to assess efficacy.

Clinical Pearls

  • CGRP‑antagonist advantage: Safe in patients with cardiovascular disease where triptans are contraindicated.
  • Once‑daily dosing simplifies adherence compared with 2–3 day regimens of many triptans.
  • Drug‑interaction caution: Because ubrogepant is CYP3A‑dependent, check for strong inhibitors (ketoconazole, clarithromycin) or inducers (rifampin, carbamazepine).
  • Use in situ: For status migrainosus, combine with an NSAID or triptan; the addition improves pain-free rates without additive CV
  • Switching: Patients previously on triptans can switch to Qulipta without a washout period, but remain watchful for cumulative hypotension.
  • Pregnancy & lactation: Limited data; avoid in early pregnancy unless clearly indicated.
  • Patient counseling: Emphasize mild GI upset is common and usually self‑limiting; advise adequate hydration, especially during high‑dose episodes.
