Almotriptan is a sulfonamide triptan with extracerebral, intracranial vasoconstrictor activity. Almotriptan selectively binds to and activates serotonin 5-HT 1B and 1D receptors in the central nervous system (CNS), thereby causing extracerebral, intracranial blood vessel constriction. This may lead to pain relief from vascular headaches. Almotriptan may also relieve vascular headaches by preventing the release of vasoactive neuropeptides from perivascular trigeminal axons in the dura mater during a migraine, by reducing extravasation of plasma proteins, and by decreasing the release of other mediators of inflammation from the trigeminal nerve.

Almotriptan is a Serotonin-1b and Serotonin-1d Receptor Agonist. The mechanism of action of almotriptan is as a Serotonin 1b Receptor Agonist, and Serotonin 1d Receptor Agonist.

FDA Label

5 Pharmacology and Biochemistry

5.1 Pharmacology

Almotriptan is a selective 5-hydroxytryptamine receptor subtype agonist indicated for the acute treatment of migraine attacks with or without aura in adults. Almotriptan is not intended for the prophylactic therapy of migraine or for use in the management of hemiplegic or basilar migraine. Almotriptan is an agonist for a vascular 5-hydroxytryptamine receptor subtype (probably a member of the 5-HT_1D family) having only a weak affinity for 5-HT_1A, 5-HT_5A, and 5-HT₇ receptors and no significant affinity or pharmacological activity at 5-HT₂, 5-HT₃ or 5-HT₄ receptor subtypes or at alpha1-, alpha2-, or beta-adrenergic, dopamine1,; dopamine2; muscarinic, or benzodiazepine receptors. This action in humans correlates with the relief of migraine headache. In addition to causing vasoconstriction, experimental data from animal studies show that Almotriptan also activates 5-HT₁ receptors on peripheral terminals of the trigeminal nerve innervating cranial blood vessels, which may also contribute to the antimigrainous effect of Almotriptan in humans.

5.5 Absorption, Distribution and Excretion

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.

Volume of Distribution

180 to 200 L

Clearance

57 L/h [healthy]

34.2 L/h [moderate renal impairment (creatinine clearance between 31 and 71 mL/min)]

9.8 L/h [severe renal impairment (creatinine clearance between 10 and 30 mL/min)]

5.6 Metabolism/Metabolites

Almotriptan has known human metabolites that include 2-hydroxy-almotriptan and methyl(2-{5-[(pyrrolidine-1-sulfonyl)methyl]-1H-indol-3-yl}ethyl)amine.

5.8 Mechanism of Action

Almotriptan binds with high affinity to human 5-HT_1B and 5-HT_1D receptors leading to cranial blood vessel constriction.
