{{/items}} {{^items}}Description
A serotonin agonist that acts selectively at 5HT1 receptors. It is used in the treatment of migraine disorders. A transdermal patch version of sumatriptan is currently in phase I trials in the U.S. under the code name NP101 (NuPathe).
Indication
For the treatment of migraine attacks with or without aura.
Mechanism of Action
The 5-HT1B and 5-HT1D receptors function as autoreceptors, which inhibit the firing of serotonin neurons and a reduction in the synthesis and release of serotonin upon activation. After sumatriptan binds to these receptors, adenylate cyclase activity is inhibited via regulatory G proteins, incrases intracellular calcium, and affects other intracellular events. This results in vasoconstriction and inhibtion of sensory nociceptive (trigeminal) nerve firing and vasoactive neuropeptide release.
Pharmacokinetics
- Absorption
- Approximately 15%
- Distribution
- * 2.7 L/kg [subcutaneous dosing]
- Metabolism
- Hepatic. In vitro studies with human microsomes suggest that sumatriptan is metabolized by monoamine oxidase (MAO), predominantly the A isoenzyme.
- Elimination
Clearance
* 1200 mL/min [Following a 6-mg SC injection]
Toxicity
Symptoms of overdose include convulsions, tremor, paralysis, inactivity, ptosis, erythema of the extremities, abnormal respiration, cyanosis, ataxia, mydriasis, salivation, and lacrimation.
