Rizatriptan was patented in 1991 and came into medical use in 1998. [5] [6] It is available as a generic medication. [4] In 2022, it was the 190th most commonly prescribed medication in the United States, with more than 2 million prescriptions. [7] [8] Rizatriptan is available in combination with meloxicam as meloxicam/rizatriptan.
The main structural difference of the triptans is the position of the sulfonamide and the side chain attached to it (see figure 1 and table 1). Rizatriptan and zolmitriptan have instead of a sulfonamide a triazole and 2-oxazolidone respectively. Another exception to the classic structure is seen on eletriptan where the nitrogen-alkyl chain ...
A systematic review found that "rizatriptan 10 mg was the only triptan with a recurrence rate greater than that of placebo". [ 24 ] There is a theoretical risk of coronary spasm in patients with established heart disease, and cardiac events after taking triptans may rarely occur.

A meta-analysis of 53 clinical trials has shown that all triptans are effective for treating migraine at marketed doses and that naratriptan, although less effective than sumatriptan and rizatriptan was more effective than placebo in reducing migraine symptoms at two hours [3] and efficacy was demonstrated in almost two thirds of subjects after four hours of treatment.
They show activity at serotonin 5-HT 1-2, dopamine D2-like and alpha1/alpha2-adrenoreceptors. [4] Their lack of selectivity leads to more adverse effects, making them second line compared to triptans. [4] However, they have been shown to prevent recurrence better than triptans. [5] Adverse effects include nausea, vomiting, paresthesia, and ...
An orally disintegrating tablet or orally dissolving tablet (ODT) is a drug dosage form available for a limited range of over-the-counter (OTC) and prescription medications. ODTs differ from traditional tablets in that they are designed to be dissolved on the tongue rather than swallowed whole.
Like all triptans, almotriptan has a high and specific affinity for serotonin 5-HT 1B/1D receptors. Binding of the drug to the receptor leads to vasoconstriction of the cranial (brain) blood vessels and thus affects the redistribution of blood flow. Almotriptan significantly increases cerebral blood flow and reduces blood flow through ...
