Description
Curator's Comment: Description was created using several sources including: https://www.ncbi.nlm.nih.gov/pubmed/10193663 | http://www.migraines.org/treatment/pro_rlpx.htm

Eletriptan (eletriptan hydrobromide, trade name Relpax) is a selective 5-hydroxytryptamine (5-HT1B/1D) serotonin receptor agonist (triptan) indicated for the acute treatment of migraine with or without aura in adults. Eletriptan binds with high affinity to 5-HT1B, 5-HT1D and 5-HT1F receptors, and has modest affinity for 5-HT1A, 5-HT1E, 5-HT2B and 5-HT7 receptors. The therapeutic activity of eletriptan for the treatment of migraine headache is thought to be due to the agonist effects at the 5-HT1B/1D receptors on intracranial blood vessels (including the arterio-venous anastomoses) and sensory nerves of the trigeminal system which result in cranial vessel constriction and inhibition of pro-inflammatory neuropeptide release. Eletriptan (Relpax) has been approved for use in the acute treatment of migraine in 51 countries and has been introduced in 17 countries including Mexico, Italy, France and Japan.

CNS Activity

Curator's Comment: Known to be CNS penetrant in rats. Human data not available. It was concluded that eletriptan, acting on perikarya and both the peripheral and the central axon terminals of primary sensory neurons, exerts its antimigraine effect by an agonist action on 5-HT1B/1D receptors throughout the entire trigeminal system, probably by passing the blood-brain-barrier because of its lipophilic character.

Approved Use

RELPAX is indicated for the acute treatment of migraine with or without aura in adults. RELPAX is not intended for the prophylactic therapy of migraine or for use in the management of hemiplegic or basilar migraine. Safety and effectiveness of RELPAX Tablets have not been established for cluster headache, which is present in an older, predominantly male population.

Sample Use Guides

The maximum recommended single dose of Relpax (eletriptan hydrobromide) is 40 mg. If after the initial dose, headache improves but then returns, a repeat dose may be beneficial. If a second dose is required, it should be taken at least 2 hours after the initial dose. If the initial dose is ineffective, controlled clinical trials have not shown a benefit of a second dose to treat the same attack. The maximum daily dose should not exceed 80 mg.
Route of Administration: Oral
The 5-hydroxytryptamine (5-HT) receptor mediation of the contraction in guinea-pig iliac arteries moderately precontracted by prostaglandin F2alpha (PGF2alpha) was characterized in vitro using eletriptan. Eletriptan contracted guinea-pig iliac arteries and the concentration-response curve for eletriptan was biphasic (first phase: 0.01-3 uM, pD2 approximately 6.6; second phase: greater or equal 10 uM).
