Almotriptan is a triptan drug for the treatment of migraine headaches. Almotriptan is marketed under the trade name Axert. Almotriptan is used for treating acute migraine headaches with or without aura (eg, dark spots, flashing lights, wavy lines). Almotriptan binds with high affinity to 5-HT1D, 5-HT1B, and 5-HT1F receptors.
Almotriptan has weak affinity for 5-HT1A and 5-HT7 receptors, but has no significant
affinity or pharmacological activity at 5-HT2, 5-HT3, 5-HT4, 5-HT6; alpha or beta
adrenergic; adenosine (A1, A2); angiotensin (AT1, AT2); dopamine (D1, D2);
endothelin (ETA, ETB); or tachykinin (NK1, NK2, NK3) binding sites.

Primary | AXERT Approved UseAlmotriptan tablets, USP are a 5HT1B/1D receptor agonist (triptan) indicated for: •Acute treatment of migraine attacks in adults with a history of migraine with or without aura (1.1) •Acute treatment of migraine headache pain in adolescents age 12 to 17 years with a history of migraine with or without aura, and who have migraine attacks usually lasting 4 hours or more (1.1) Important Limitations: •Use only after a clear diagnosis of migraine has been established (1.2) •In adolescents age 12 to 17 years, efficacy of almotriptan tablets on migraine-associated symptoms was not established (1.2) •Not intended for the prophylactic therapy of migraine (1.2) •Not indicated for the treatment of cluster headache (1.2) 1.1 Acute Treatment of Migraine Attacks Adults Almotriptan tablets, USP are indicated for the acute treatment of migraine attacks in patients with a history of migraine with or without aura. Adolescents Age 12 to 17 Years Almotriptan tablets are indicated for the acute treatment of migraine headache pain in patients with a history of migraine attacks with or without aura usually lasting 4 hours or more (when untreated). 1.2 Important Limitations Almotriptan tablets should only be used where a clear diagnosis of migraine has been established. If a patient has no response for the first migraine attack treated with almotriptan tablets, the diagnosis of migraine should be reconsidered before almotriptan tablets are administered to treat any subsequent attacks. In adolescents age 12 to 17 years, efficacy of almotriptan tablets on migraine-associated symptoms (nausea, photophobia, and phonophobia) was not established. Almotriptan tablets are not intended for the prophylactic therapy of migraine or for use in the management of hemiplegic or basilar migraine [see Contraindications (4.7) Launch Date2001 |

Sample Use Guides
Adults and adolescents age 12 to 17 years: 6.25 mg or 12.5 mg single
dose; may repeat after 2 hours if headache returns; benefit of second dose
in patients who have failed to respond to first dose has not been
established; maximum daily dose 25 mg
Patients with hepatic or severe renal impairment: 6.25 mg starting dose;
maximum daily dose 12.5 mg

In vitro Almotriptan showed selectivity of action for migraine-related human arteries (i.e. contractile EC(50) of 30 and 700 nm for meningeal and temporal arteries, respectively), whereas the effect on arteries supplying blood to the brain was lower.
