What is Eletriptan?
Eletriptan is a medication primarily used to treat acute migraine attacks. It belongs to a class of drugs known as triptans, which are specifically designed to alleviate the symptoms of migraines. Eletriptan works by targeting serotonin receptors in the brain, helping to reduce headache pain and associated symptoms such as nausea and sensitivity to light and sound. It is important to note that Eletriptan is not intended for the prevention of migraines but rather for the relief of symptoms once a migraine has started.
Uses of Eletriptan
Eletriptan is approved for the treatment of acute migraine attacks in adults. It is effective in relieving the pain and discomfort associated with migraines, including the accompanying symptoms like nausea and photophobia (sensitivity to light). It is not used for other types of headaches, such as tension headaches or cluster headaches. Patients should take Eletriptan as soon as they notice the onset of a migraine for optimal effectiveness.
วิธีการทำงาน
Eletriptan works by stimulating specific serotonin receptors in the brain, known as 5-HT1B and 5-HT1D receptors. When a migraine occurs, certain chemicals in the brain cause blood vessels to dilate, leading to pain. Eletriptan helps to constrict these blood vessels, reducing swelling and alleviating pain. In simpler terms, it helps to restore balance in the brain's chemistry, which can become disrupted during a migraine attack.
การให้ยาและการบริหาร
The standard adult dosage of Eletriptan is typically 20 mg or 40 mg taken orally as a tablet. Patients should take the medication as soon as they experience migraine symptoms. If the migraine does not improve after two hours, a second dose may be taken, but the total daily dose should not exceed 80 mg. Eletriptan is not recommended for use in children or adolescents under 18 years of age, as safety and efficacy in this population have not been established.
Side Effects of Eletriptan
Common side effects of Eletriptan may include:
- เวียนหัว
- อาการง่วงนอน

Benefits of Eletriptan
The primary benefit of Eletriptan is its effectiveness in providing rapid relief from migraine symptoms. Many patients find that it works quickly, often within 30 minutes to two hours after taking the medication. Additionally, Eletriptan has a favorable side effect profile compared to some other migraine treatments, making it a preferred choice for many individuals. Its ability to alleviate not just headache pain but also associated symptoms like nausea enhances its overall utility in migraine management.
Contraindications of Eletriptan
Certain individuals should avoid using Eletriptan, including:
- Those with ischemic heart disease, history of stroke or TIA, or peripheral vascular disease
- Patients with uncontrolled high blood pressure
- Use in pregnancy and breastfeeding is not recommended unless clearly needed

It is crucial for patients to discuss their medical history with their healthcare provider to determine if Eletriptan is a safe option for them.
ข้อควรระวังและคำเตือน
Before using Eletriptan, patients should undergo a thorough medical evaluation, especially if they have a history of cardiovascular issues. Regular monitoring of blood pressure may be necessary for those with hypertension. Patients should also be cautious about using Eletriptan in conjunction with other medications that affect serotonin levels, as this can lead to a serious condition known as serotonin syndrome.
