Effective occipital nerve stimulation during pregnancy in a cluster headache patient Dear Editor, Cluster headache is a rare primary headache disorder characterized by attacks of excruciating, intermit-ting short-lasting unilateral temporal or orbital pain (1). Cluster headache in pregnancy can be difficult to treat because of a limitation in treatment options. The only acute treatment that is ...

We encountered two patients with sumatriptan-induced reversible cerebral vasoconstriction syndrome (RCVS). The present patients were taking sumatriptan for the first time because they had been tentatively diagnosed with a migraine. On reviewing the literature, we found nine other cases of triptan-induced RCVS, predominantly among women aged 30 to 40 years. RCVS has been precipitated by triptan ...

QUESTION I am seeing more and more children and adolescents with headaches that can be defined as migraine headache. I have read about intranasal sumatriptan as an abortive therapy. Is this an effective treatment? ANSWER Acute migraine headache among children and adolescents is common and treatment is challenging. Intranasal sumatriptan is a safe and mostly effective option for children and a...

succinate) was the first triptan medication to target the nerves and blood vessels believed to trigger a total migraine (including throbbing pain, nausea, and sensitivity to light and sound, with or without aura). The first triptan to receive Food and Drug Administration (FDA) approval for the acute treatment of migraines in adults, IMITREX has treated more than 750 million migraines in the pas...

OBJECTIVE To understand a possible role for transient potential receptor vanilloid 1 (TRPV1) ion channels in sumatriptan relief of pain mediated by trigeminal nociceptors. BACKGROUND TRPV1 channels are expressed in small nociceptive sensory neurons. In dorsal root ganglia, TRPV1-containing nociceptors mediate certain types of inflammatory pain. Neurogenic inflammation of cerebral dura and blo...

An improved multistep synthesis of {3-(2-dimethylamino-ethy1)-2-[3-(2dimethylaminoethyl)-1H-indol-5-ylmethyl]-1H-indol-5-yl}-N-methyl-methanesulfonamide, the main Sumatriptan impurity, is described, as a model for other related triptan derivatives.

A green method for the synthesis of high-performance diketopyrrolopyrrole pigments using diethyl succinate in the presence of mixture of ionic liquids is reported. Although, alkaline condition is needed in the succinate ester route for synthesis of the pigments, in the present study, the replacement possibility of conventional organic base by mixture of BMIMOH and BMIMBF4 ionic liquids was inve...
