A beta blocker eye drop that prices lower than $10 might be able to assist acute migraine victims by stopping the acute assaults from worsening or no less than lessening their depth, in response to a number of ophthalmologists.
The docs discover that timolol eye drops (0.5 p.c) which might be authorized for a sure eye dysfunction, when used off-label, are an efficient and comparatively protected therapy for sufferers with acute migraine when used instantly after symptom onset.
Dr. John C. Hagan, an ophthalmologist with over 50 years of expertise stated that for some folks, treating their acute migraines includes utilizing timolol together with different medicines.
“So most people that we name success, don’t use the beta blocker drops as sole remedy,” Hagan advised The Epoch Occasions. “They use like an analgesic, Tylenol or aspirin, or they use a non-steroidal anti-inflammatory like Advil or one thing like that.”
Dr. Melissa Toyos, an oculofacial plastic surgeon who developed migraines in her late 20s, depends on a number of completely different medicines to abort the acute migraine assaults.
“I’ve entry to all the migraine meds together with lots of the pricier ones and paradoxically, the triptans have precipitated chest ache and minimal enhancements whereas otc [over-the-counter] Excedrin and beta blockers (together with CGRP inhibitors and anti-nausea sublingual tablets) have develop into my mainstay,” Toyos stated in an e mail to The Epoch Occasions.
She stated that the beta blocker eye drops assist with “nipping the migraine within the bud earlier than it turns into full-blown and avoiding a number of the much less fascinating unwanted side effects of different headache medicines.”
Beta blockers, often known as beta-adrenergic blocking brokers, have been round for the reason that Sixties (pdf) and had been initially authorized to deal with cardiovascular problems. They work by blocking the motion of adrenaline—a stress hormone launched by the adrenal glands—to permit the guts charge to decelerate and the blood vessels to loosen up, thus bettering blood circulation.
“When docs prescribe beta blockers in capsule varieties for coronary heart palpitation [patients], a lot of them reported that their migraines received higher,” Hagan stated.
This unintentional discovering has led to beta blockers turning into one of many major remedy choices in stopping power migraines (15 or extra complications monthly) when the drug is taken in capsule type. But, whereas the tablets are profitable in treating power migraine, they don’t seem to be efficient for acute ache.
Different situations that these medicines can deal with embody tremors, nervousness, and hypertension.
In 1978, a liquid type of a beta blocker, timolol eye drop, was authorized by the FDA (pdf) to deal with glaucoma, an eye fixed illness that may result in imaginative and prescient loss.
Sufferers who had been being handled for glaucoma reported that their “migraines received higher once they had been placing their beta-blocker eye drops in every single day,” Hagan stated.
In 2013, Hagan’s colleague, a glaucoma specialist, shared his scientific experiences utilizing timolol eye drops for therapy of acute migraines and urged Hagan’s daughters, who had developed migraines of their 30s, attempt the remedy as quickly as signs of a migraine started.
The dialog sparked an curiosity in Hagan who needed to know why the attention drops had been efficient for acute migraine however tablets weren’t. Hagan dove into the literature and the restricted research on beta blocker eye drops, and after many hours of poring by the information and discussions, he and his colleague skilled a eureka second.
“Then, it type of dawned on us. It didn’t take that lengthy [to realize] that in the event you take a capsule, a migraine capsule, it has to undergo the abdomen, be digested, after which undergo the liver the place a few of it’s drained off,” Hagan stated. “It takes a protracted, very long time to get a therapeutic stage, if a therapeutic stage is reached in any respect.”
“And that was why it doesn’t work [for acute migraine] when it’s taken in capsule type.”
In a 2014 examine of seven sufferers with acute migraines handled with beta blocker eye drops, wherein Hagan is co-author, the attention drops are efficient as a result of they obtain therapeutic blood ranges “inside minutes” of being administered to the sufferers. The attention drops are rapidly absorbed by the tear duct onto the nasal mucosa and into the veins the place they go into circulation.
The biggest double-masked randomized trial up to now on therapy of acute migraine with timolol eye drops was a examine from India. Researchers examined a complete of 619 acute assaults in 50 sufferers. The examine, printed in JAMA Ophthalmology on Oct. 1, 2020, discovered that timolol was efficient in assuaging migraine ache in comparison with placebo.
“The outcomes noticed give additional help to the speculation that topically utilized beta blockers could also be an efficient and cheap abortive migraine remedy for some sufferers, with fewer hostile results,” the authors wrote.
Battle to Get FDA Approval
Hagan and his colleague, for the previous eight years, have reached out to tutorial establishments and greater than 50 drug producers who’ve the capability to develop and fund a part 3 randomized trial to show and make sure that timolol is efficient, protected, and useful for acute migraine. A big scientific trial is required previous to making use of for FDA approval.
Whereas timolol eye drops could also be used off-label for acute migraine, docs should still be delay from prescribing it attributable to ignorance concerning learn how to greatest use it outdoors of what it’s authorized for. However which may be remedied if the FDA approves it for a brand new indication, equivalent to acute migraine, as all the required info will likely be out there to assist the doctor decide.
The responses from prescribed drugs weren’t what Hagan had anticipated, with many initially expressing curiosity however later rejecting their proposal.
“As of February 2022, the response from pharma has been virtually uniform,” Hagan stated in an article printed in Missouri Medication, including that the three causes given for the rejection had been that it might be troublesome to patent the drugs, the drug firm didn’t wish to develop a less expensive product that may compete with their “present costlier product line,” and that there’s not “sufficient revenue on this product with or with out mental property to fund it.”
With out revenue to make, neuro-ophthalmologist Dr. Bradley Katz stated, prescribed drugs received’t fund the examine.
“No drug firm goes to co-sponsor it as a result of it’s generic, so there’s no cash to be made. That’s most likely the most important factor,” Katz advised The Epoch Occasions.
Off-label use is when a drug is used for every other medical situation, or given in a distinct method or dose than what it’s federally authorized for.
Since 2013, Hagan has been prescribing timolol eye drops to acute migraine sufferers. Two years in the past, he labored with a family-owned pharmacy, O’Brien Pharmacy, to develop a compounded timolol nasal spray to make use of off-label that may enable for even sooner absorption to supply ache reduction.
A nasal spray could be the “best, quickest, and simplest option to ship” the remedy and it might additionally assist individuals who have problem correctly utilizing the attention drops, Hagan stated.
“The absorption of beta blockers topical to the attention, sublingual, and nasal has been studied,” Hagan and his co-authors wrote in an article printed within the Worldwide Journal of Pharmaceutical Compounding in 2020. “Nasal is the quickest (100%) being equal to intravenous administration in a examine of 80 wholesome volunteers.”
Katz has been utilizing the beta blocker eye drop to deal with his personal migraines and in addition prescribing it to sufferers. He advises that acute migraine victims focus on with their physician if they need to attempt timolol.
“For some sufferers, it may be very efficient … it’s so cheap,” Katz stated, including that the unwanted side effects are only a few in wholesome folks. “It’s an eye fixed drop that I usually will advocate to sufferers as like a first-line therapy in the event that they really feel like they’re beginning to get a [migraine] headache.”
“They will simply pop in a few drops, wait 20 minutes. In the event that they’re not getting higher, they will put in one other set of drops. And if it really works, nice, and if it doesn’t work, nicely then you definately haven’t actually misplaced something,” he added.
Dr. Sean Gratton, an ophthalmologist and a co-author of a 2018 small examine that examined whether or not timolol was efficient in aborting acute migraines, stated in an article printed in EyeNet journal that the has “discovered them [timolol eye drops] to be efficient in a subset of sufferers who take them as wanted.”
Whereas comparatively protected to make use of, timolol may cause some widespread unwanted side effects equivalent to dry eyes, burning within the eye, or pink eyelids. Timolol is just not beneficial for folks with situations like bronchial asthma, emphysema, or an irregular heartbeat, in response to Katz. There may be concern that the remedy could worsen their situation.
As well as, individuals who’ve had a unfavorable response to beta blockers ought to keep away from this remedy, in response to Hagan.
Lanette Todd, an ophthalmic technician, has used timolol eye drops off-label for greater than seven years with none challenge though she has bronchial asthma.
“I don’t have any underlying points, so it was by no means an issue for me,” Todd advised The Epoch Occasions.
Todd was identified 18 years in the past with ocular migraine that causes short-term imaginative and prescient issues in a single eye that lasts for about an hour.
Previous to utilizing timolol eye drops, Todd stated she took an aspirin and caffeine and “simply wait it out.”
She stated taking the attention drop sublingually, or beneath her tongue, offered faster reduction than as eye drops.
“So I began out placing them in my eye, like one drop in every eye, and it helped somewhat bit,” Todd stated. “Then we found in the event you put it beneath your tongue, put the drops in, then it might go to your system sooner, form of get in your bloodstream so much sooner by your saliva.”
Todd’s teenage daughter and sister additionally endure from migraines and the beta blocker eye drops have helped with the acute assaults.
The Nationwide Library of Medication says that migraines “end result from a mixture of genetic, environmental, and way of life components.” As well as, “variations in lots of genes have been discovered to be related to the event of migraines with or with out aura.”
Carolyn Csongradi has suffered from migraines for over 40 years and stated the attention drops had been very efficient in treating her acute assaults. However she’s needed to discontinue the remedy due to the sinus congestion she skilled as a aspect impact.
Csongradi is taking a every day anti-seizure drug, topomax, that can be used off-label to forestall migraine complications. Nevertheless, the drug doesn’t cease a migraine headache that has already begun.

Federally Accepted Medicine
A number of newer medication for acute migraine have been authorized previously a number of years.
Three medicines, which contain concentrating on a protein within the mind and nervous system known as calcitonin gene-related peptide (CGRP) that “may cause blood vessels to dilate and trigger irritation and migraine headache ache,” had been authorized in 2019 to lower the variety of acute assaults. They’re monoclonal antibodies administered beneath the pores and skin as soon as each month.
