Frovatriptan, sold under the brand name Frova, is a triptan drug developed by Vernalis for the treatment of migraine headaches [1] and for short term prevention of menstrual migraine. [2] The product is licensed to Endo Pharmaceuticals in North America and Menarini in Europe.
Side chains of the surrounding amino acids can have an effect on the binding of the nitrogen atom, mainly three Phe can affect the methyl groups bound to the nitrogen atom (not shown in figure 4). [11] [12] [13] Eletriptan has higher affinity for the receptor, which is probably a result of the bulky substituents of the structure.
Triptans have few side effects if used in correct dosage and frequency. The most common adverse effect is recurrence of migraine. A systematic review found that "rizatriptan 10 mg was the only triptan with a recurrence rate greater than that of placebo". [24]
The most common side effects [14] reported by at least 2% of patients in controlled trials of sumatriptan (25-, 50-, and 100-mg tablets) for migraine are atypical sensations (paresthesias and warm/cold sensations) reported by 4% in the placebo group and 5–6% in the sumatriptan groups, pain and other pressure sensations (including chest pain ...
A 1998 review has found such side effects to rarely occur in most patients taking triptans. [ 3 ] [ 4 ] One clinical trial showed that 200 mg lasmiditan provided pain freedom by 2 hours in 32% of individuals with migraine attacks of moderate or severe intensity, and 100 mg lasmiditan did so in 28%, compared with 15% after a placebo. [ 5 ]
Side effects are similar to other triptan medications, with the incidence of side effects reportedly being lower than sumatriptan, and side effects occurring rarely except when above 2.5mg. [ 5 ] [ 6 ] The risk of triptan side effects is also in general low, according to a systematic review. [ 7 ]
Less-common side effects can include excess air or gas in your stomach, burping, heartburn, indigestion, fast heartbeat, low blood sugar, low energy and fatigue, or even gallstones, Dr. Comite says.
The lack of affinity for these receptors might result in fewer side effects related to vasoconstriction compared to triptans in susceptible people, such as those with ischemic heart disease, Raynaud's phenomenon or after a myocardial infarction, [8] although a 1998 review has found such side-effects to rarely occur in people taking triptans.
