A paper presented at the annual meeting of the American Headache Society that is taking place this weekend examined the risk of major adverse cardiovascular events (MACE) in patients with preexisting cardiovascular (CV) conditions. The researchers compared the risk of triptans with that of opioid/barbiturate drugs (drugs like codeine, Vicodin, Percocet, Fioricet) and non-steroidal anti-inflammatory drugs (NSAIDs).
They used Mass General Brigham Research Patient Data Registry database to identify 12,121 prescriptions. Of these, 33% were for triptans, 50% for opioid/barbiturate drugs, and 17% for NSAIDs.
MACE occurred in 1% of those taking triptans, 4.5% taking opioid/barbiturate drugs, and 3.8% taking NSAIDs.
This goes against the established dogma of avoiding triptans in patients with CV problems. Instead, doctors are advised to offer opioid/barbiturate drugs or NSAIDs. Unfortunately, according to the FDA-approved package insert, triptans are contraindicated in patients with CV, cerebrovascular, and peripheral vascular problems. This contraindication came about from purely theoretical reasoning rather than real-life experience. Triptans do in fact have mild vasoconstriction properties and it is possible that someone with severe occlusion of coronary or other blood vessels can have dangerous constriction of a blood vessel. There have been also reports of healthy people developing cardiovascular complications, but those are very rare.
This new data indicates that triptans are safer than the alternatives most doctors prescribe. The two alternatives described in the report also carry significant risks of addiction, stomach ulcers, and bleeding. It is very likely, however, that doctors will continue to avoid prescribing triptans in this population because of legal concerns and ingrained habits.
We do have two new classes of drugs to treat an acute migraine attack that are proven to be safe in patients with CV conditions. These are gepants – rimegepant (Nurtec) and ubrogepant (Ubrelvy) as well as ditans – lasmiditan (Reyvow). These drugs are very expensive and insurers always require that patients first try other drugs.
