Overview

What is Relpax?

RELPAX (eletriptan hydrobromide) tablets contain eletriptan hydrobromide, which is a selective 5-hydroxytryptamine 1B/1D (5-HT1B/1D) receptor agonist. Eletriptan hydrobromide is chemically designated as (R)-3-[(1-Methyl-2-pyrrolidinyl)methyl]-5-[2-(phenylsulfonyl)ethyl]-1H-indole monohydrobromide, and it has the following chemical structure:

The empirical formula is CHNOS . HBr, representing a molecular weight of 463.43. Eletriptan hydrobromide is a white to light pale colored powder that is readily soluble in water.

Each RELPAX Tablet for oral administration contains 24.2 or 48.5 mg of eletriptan hydrobromide equivalent to 20 mg or 40 mg of eletriptan, respectively. Each tablet also contains the inactive ingredients microcrystalline cellulose NF, lactose monohydrate NF, croscarmellose sodium NF, magnesium stearate NF, titanium dioxide USP, hypromellose, triacetin USP and FD&C Yellow No. 6 aluminum lake.

What are the available doses of Relpax?

Tablets: 20 mg and 40 mg ()

What should I talk to my health care provider before I take Relpax?

Pregnancy: based on animal data, may cause fetal harm ()

How should I use Relpax?

RELPAX is indicated for the acute treatment of migraine with or without aura in adults.

Limitations of Use:

The maximum recommended single dose is 40 mg.

In controlled clinical trials, single doses of 20 mg and 40 mg were effective for the acute treatment of migraine in adults. A greater proportion of patients had a response following a 40 mg dose than following a 20 mg dose .

If the migraine has not resolved by 2 hours after taking RELPAX, or returns after transient improvement, a second dose may be administered at least 2 hours after the first dose. The maximum daily dose should not exceed 80 mg.

The safety of treating an average of more than 3 migraine attacks in a 30-day period has not been established.

What might happen if I take too much Relpax?

The elimination half-life of eletriptan is about 4 hours , therefore monitoring of patients after overdose with eletriptan should continue for at least 20 hours or longer while symptoms or signs persist.

There is no specific antidote to eletriptan.

It is unknown what effect hemodialysis or peritoneal dialysis has on the serum concentration of eletriptan.


How should I store and handle Relpax?

Store at 20°C to 25°C (68°F to 77°F); excursions permitted between 15°C to 30°C (59°F to 86°F) [see USP Controlled Room Temperature].RELPAX Tablets containing 20 mg or 40 mg eletriptan (base) as the hydrobromide salt.

Clinical Pharmacology

Eletriptan binds with high affinity to 5-HT, 5-HT and 5-HT receptors, has modest affinity for 5-HT, 5-HT, 5-HT and 5-HT receptors.

Migraines are likely due to local cranial vasodilatation and/or to the release of sensory neuropeptides (vasoactive intestinal peptide, substance P and calcitonin gene-related peptide) through nerve endings in the trigeminal system. The therapeutic activity of RELPAX for the treatment of migraine headache is thought to be due to the agonist effects at the 5-HT 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.

Non-Clinical Toxicology
RELPAX is contraindicated in patients with:

Although the pressor activity of desmopressin acetate is very low compared to the antidiuretic activity, use of large doses of intranasal desmopressin acetate with other pressor agents should only be done with careful patient monitoring. The concomitant administration of drugs that may increase the risk of water intoxication with hyponatremia, (e.g., tricyclic antidepressants, selective serotonin re-uptake inhibitors, chlorpromazine, opiate analgesics, NSAIDs, lamotrigine and carbamazepine) should be performed with caution.

RELPAX should only be used where a clear diagnosis of migraine has been established.
