Eletriptan
Eletriptan, sold as Relpax, treats the headache phase of a migraine attack. This shelf carries one product in 20 mg and 40 mg tablets.
Key points
- Eletriptan is a triptan (selective serotonin receptor agonist) used to treat the headache phase of a migraine attack in adults.
- It stops an active attack but does not prevent future migraines or reduce how often they occur.
- Eletriptan is contraindicated in people with coronary artery disease, a history of stroke, or those taking potent CYP3A4 inhibitors such as ketoconazole or erythromycin.
How does Eletriptan work?
Relpax contains eletriptan, which binds to serotonin receptors on blood vessels in the brain and causes them to narrow. This reduces the swelling and release of inflammatory chemicals around the trigeminal nerve that drive migraine pain, nausea, and sensitivity to light.
