Eletriptan (ELT)

Eletriptan is a second generation triptan drug intended for treatment of migraine headaches. It is used as an abortive medication, blocking a migraine attack which is already in progress.Eletriptan is believed to reduce swelling of the blood vessels surrounding the brain. This swelling is associated with the head pain of a migraine attack. Eletriptan blocks the release of substances from nerve endings that cause more pain and other symptoms like nausea, and sensitivity to light and sound. It is thought that these actions contribute to relief of symptoms by eletriptan. Eletriptan has no significant affinity or pharmacological activity at adrenergic alpha1, alpha2, or beta; dopaminergic D1 or D2; muscarinic; or opioid receptors. Eletriptan could be efficiently co-administrated with nitric oxide synthase (NOS's) inhibitors for the treatment of NOS-dependent diseases.
