Description
Almotriptan is a triptan drug for the treatment of migraine headaches. Almotriptan is in a class of medications called selective serotonin receptor agonists. It works by narrowing blood vessels in the brain, stopping pain signals from being sent to the brain, and stopping the release of certain natural substances that cause pain, nausea, and other symptoms of migraine. Almotriptan does not prevent migraine attacks.

Toxicity Profile
Route of ExposureOral
Mechanism of ToxicityAlmotriptan binds with high affinity to human 5-HT1B and 5-HT1D receptors leading to cranial blood vessel constriction.
MetabolismHepatic. Route of Elimination: Almotriptan is eliminated primarily by renal excretion (about 75% of the oral dose), with approximately 40% of an administered dose excreted unchanged in urine. Approximately 13% of the administered dose is excreted via feces, both unchanged and metabolized. Half Life: 3-4 hours
Toxicity ValuesNot Available
Lethal DoseNot Available
Carcinogenicity (IARC Classification)No indication of carcinogenicity to humans (not listed by IARC).
Uses/SourcesAlmotriptan is indicated for the acute treatment of migraine with or without aura in adults. [Wikipedia]
Minimum Risk LevelNot Available
Health EffectsNot Available
SymptomsNausea, drowsiness, dizziness, diarrhea, headache, sweating, or dry mouth may occur.
TreatmentGastrointestinal decontamination (i.e., gastric lavage followed by activated charcoal) should be considered in patients suspected of an overdose with Almotriptan. Clinical and electrocardiographic monitoring should be continued for at least 20 hours, even if clinical symptoms are not observed. (2)
