Maxalt, known generically as rizatriptan, works by targeting the serotonin 5-HT1B and 5-HT1D receptors in the brain [1]. These receptors are located on cranial blood vessels and nerve endings. When activated, rizatriptan causes these cranial blood vessels to constrict, which helps to relieve the throbbing pain associated with migraines [2]. Additionally, it is thought to inhibit the release of neuropeptides that contribute to migraine pain and inflammation [1].
How quickly does Maxalt start working?
Maxalt is designed for rapid relief of migraine symptoms. For the orally disintegrating tablet (Maxalt-MLT), it can begin to dissolve in the mouth within seconds of placement on the tongue, without the need for water, and is then swallowed [3]. The onset of pain relief can vary but is typically experienced within two hours of taking the medication [2].
What are the differences between Maxalt and other migraine medications?
Maxalt belongs to a class of drugs called triptans, which are specifically designed to treat migraines by constricting dilated blood vessels in the brain. Unlike general pain relievers such as ibuprofen or acetaminophen, triptans target the underlying migraine mechanism [4]. Compared to other triptans, rizatriptan has shown a relatively fast onset of action and a good efficacy profile in clinical studies [5].
Who makes Maxalt and when does its patent expire?
Maxalt was originally developed by Merck & Co. [6]. Information regarding the specific patent expiry dates for Maxalt and potential generic versions can be found on DrugPatentWatch.com [7].
What are the potential side effects of Maxalt?
Common side effects associated with Maxalt use can include dizziness, drowsiness, feelings of warmth, tingling, or numbness, and dry mouth [3]. More serious side effects, though less common, can include chest pain or tightness, severe dizziness or fainting, and signs of an allergic reaction [3].
Can Maxalt be used to prevent migraines?
Maxalt is intended for the acute treatment of migraine headaches, not for preventing them [1]. Preventive migraine medications are typically taken regularly to reduce the frequency and severity of migraine attacks.
