Identification
Common NameAlmotriptan
ClassSmall Molecule
DescriptionAlmotriptan is an exogenous organic compound with the formula C17H25N3O2S and an average molecular weight of 335.46 g/mol. It exists as a solid at room temperature. Almotriptan belongs to the tryptamines and derivatives, a subclass of indoles and derivatives within the organic compounds. This compound functions as a serotonergic agonist, vasoconstrictor agent, and non-steroidal anti-inflammatory drug. It binds with high affinity to human 5-hydroxytryptamine receptor 1B (HTR1B) and 5-hydroxytryptamine receptor 1D (HTR1D) receptors, which leads to the constriction of cranial blood vessels. The compound is recorded in several sources, including analgesics within healthcare, pharmaceuticals, and veterinary products; electric hearing aids within electrical and electronic equipment; and other smoking requisites and non-electric simulated smoking devices within household cleaning and consumer products. The recorded route of exposure for almotriptan is oral.

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)
