The Triptans

Bigal, Marcelo E., Krymchantowski, Abouch V., Hargreaves, Richard 01 May 2009 (has links)
The migraine-specific triptans have revolutionized the treatment of migraine and are currently the drugs of choice to treat a migraine attack in progress. Over the past 15 years, triptans were released in rAβid succession, with each one demonstrating some specific pharmacokinetic properties that may be translated into clinical advantages. Triptans share many similarities, but also have important differences from one another. Accordingly, herein we discuss the class of the triptans. We first define the trigeminovascular system and its importance in migraine pain, then discuss the mechanism of action of the triptans and contrast the evidence supporting the use of different triptans. We close with our view of the future and hopes for the next generation of antimigraine therAβies.

Maternal chronic conditions and risk of reproductive and perinatal outcomes

Crowe, Holly Michelle 20 April 2022 (has links)
Individuals with chronic medical conditions are at an increased risk for adverse reproductive and perinatal outcomes. However, there is limited condition-specific information on the reproductive and perinatal implications of chronic conditions and their associated treatments. In this dissertation, we focus on thyroid disorders and migraines, two relatively common chronic conditions among females of reproductive age, and three distinct reproductive outcomes, spanning from preconception to delivery. In study one, we analyzed the association between thyroid disorders and fecundability, the per-cycle probability of conception among non-contracepting couples, using data from Pregnancy Study Online (PRESTO), a preconception cohort study of pregnancy planners in the United States and Canada. We did not find an association between a diagnosis of hypothyroid, hyperthyroid, thyroid autoimmunity, or thyroid nodules/thyroid cancer and fecundability. We also found no association between thyroid medication use or non-use among individuals with a thyroid disorder and fecundability. In the second study, we focused on migraines and spontaneous abortion (SAB), which is pregnancy loss before twenty weeks gestation, also using PRESTO data. We found that a history of migraines is not independently associated with SAB risk in females, but that routine use of medication for migraines during the preconception period may be associated with an increased risk of SAB. In the third study, we focused on the association between migraines and hypertensive disorders of pregnancy (HDOP), which include gestational hypertension and preeclampsia. We used data from the Clinical Practice Research Datalink Gold, a longitudinal database of de-identified patient records from hundreds of primary care practices in the United Kingdom. We found that while migraines overall are associated with a small increase in risk of HDOP, this increase is most substantial among those with pre-pregnancy migraines that persist in the first trimester of pregnancy. Overall, we observed that while a history of diagnosed thyroid disorder or migraines ascertained via self-report during the preconception period may not be associated with the reproductive and perinatal outcomes we studied, certain subgroups of individuals with migraines may be at increased risk of SAB or HDOP. Migraine severity and persistence in the first trimester are likely important factors in determining the magnitude of this increased risk. Nuanced research into chronic conditions with a disproportionate disease burden among females of reproductive age will guide and improve reproductive health care for individuals with chronic conditions. This dissertation aims to address these gaps in the literature by exploring the relationship between two chronic conditions and three reproductive and perinatal outcomes: thyroid disorders and fecundability, migraines and spontaneous abortion, and migraines and hypertensive disorders of pregnancy. / 2023-04-20T00:00:00Z
