B.Who discovered it?
A. Relpax
B. Pfizer Inc.
Eletriptan acts as an agonist at these TWO serotonin receptors.
5-HT1B and 5-HT1D
Pfizer tested Eletriptan using this type of study design.
A double blind placebo controlled trial - neither the researchers nor participants knew who received the drug or placebo.
Common side effects of triptans?
Triptan sensation: including flushing, tingling, and chest tightness?
A. Eletriptan belongs to this class of drugs.
B. What type of headache does it treat?
A.Triptans
B.Migraines
Name AND describe some of the non-active substances (excipients) in Eletriptan.
Microcrystalline, cellulose and lactose
these do not treat migraines directly but help with tablet stability, absorption, and manufacturing
When Eletriptan approved by the FDA for acute migraine treatment in adults.
2002.
What is unique to Eletriptan when compared to other migraine medication.
Eletriptan is not a habit-forming, meaning patients can safely stop taking it without experiencing withdrawal symptoms.
Severe side effects occur in roughly this percent of users.
1%
what is CYP3A4 + how does it relate to Eletriptan
It is a liver enzyme that metabolizes Eletriptan
inhibition can lead to elevated drug levels and increase the risk of toxicity or serotonin syndrome.
Why did Pfizer issue a nationwide voluntary recall of Relpax 40 mg tablets
The recall was a precautionary measure, because some tablets did not meet microbiological safety standards. There was a potential contamination with bacteria.
No patient injuries or adverse events were reported.
Eletriptan should be avoided in patient's with these heart-realted conditions
Coronary artery disease, stroke history, or uncontrolled hypertension
A. How can one obtain Relpax?
B.What dosage does it come in?
A. Relpax must be prescribed by a healthcare provider
B.Controlled doses of 20-40mg with a max of 80 mg, misuse or excessive dosing can lead to toxicity ad serious adverse effects
Eletriptan contains an indole ring which mimcis this neurotransmitter?
What is serotonin?
Why is Eletriptan consider a "superior" drug for migraine relief.
It has a 50% oral bioavailability meaning a higher proportion of the dose reaches the bloodstream and act on target tissues.
Explain the effect Eletriptan can have on athletes.
Not a banned substance of the NCAA, Eletriptan can decrease athletic performance, and pose cardiovascular risks in active individuals due to vasoconstriction and side effect like dizziness, drowsiness, and weakness?
Eletriptan was designed to improve potency in this part of the body, contributing to its rapid relief of moderate to severe migraines?
The Central Nervous System
Explain how Eletriptan helps to relieve migraine symptoms.
it binds selectively to 5-HT1B receptors in the meningeal and coronary arteries to cause vasoconstriction,
while simultaneously activating 5-HT1D receptors at the trigeminal nerve endings to inhibit the release of CGRP, a peptide responsible for neurogenic inflammation and pain signaling,
ultimately reducing headache pain, throbbing, and associated symptoms such as nausea, light, and sound sensitivity.
What do the clinical trials show?
Eletriptan is generally well-tolerated it crosses the blood-brain barrier more effectively than some older triptans allowing better central nervous system distribution.
what is the life-threatening condition that can occur in Eletriptan is taken too close to other serotongeric drugs and what are the symptoms.
Serotonin syndrome - condition caused by EXCESSIVE activation of seotonin (5-HT) receptors.
symptoms include: anxiety, tremors , seizures, or even coma
