Eletriptan [CAS: 143322-58-1], developed by Pfizer Inc, is a second-generation triptan drug designed to alleviate migraine headaches. It acts as a serotonergic agonist, exerting vasoconstrictor effects, and also possesses properties of a non-steroidal anti-inflammatory drug.
Eletriptan: Use and Commercial Availability
Eletriptan, available under Relpax, is an indole compound for treating migraines in adults with or without aura. It interacts with drugs metabolized by cytochrome P-450, including CYP-3A4.
Eletriptan Structure and Mechanism of Action 
The chemical name of Eletriptan is 3-[[(2R)-1-Methyl-2-pyrrolidinyl]methyl]-5-[2-(phenylsulfonyl)ethyl]-1H-indole. Its chemical formula is C22H26N2O2S, and its molecular weight is approximately 382.5 g/mol.
Eletriptan binds to o 5-HT1B, 5-HT1D, and 5-HT1F receptors located on intracranial blood vessels, leading to vasoconstriction and relief of migraine headaches.
Eletriptan Impurities and Synthesis
The analysis and control of impurities in Eletriptan, a migraine medication, are crucial to ensure its quality and safety. Various techniques such as chromatography, spectroscopy, and mass spectrometry help identify and quantify impurities. Impurity profiling helps determine their chemical composition, structure, and toxicity. Strict control measures during the manufacturing process1 help minimize impurity formation, and regulatory guidelines specify acceptable limits for impurities in pharmaceutical products. Thorough analysis and effective control of Eletriptan impurities contribute to their quality and efficacy for patient use.
Daicel Pharma offers a comprehensive Certificate of Analysis (CoA) for Eletriptan impurity standards, including Eletriptan Impurity 10, Eletriptan Impurity 8, and Eletriptan Impurity 9. They generate from an analytical facility that complies with cGMP standards. The CoA provides a detailed characterization report with data obtained through techniques such as 1H NMR, 13C NMR, IR, MASS, and HPLC purity analysis. We give additional data like 13C-DEPT upon request. Daicel Pharma synthesizes unknown Eletriptan impurities or degradation products. Every delivery has a complete characterization report.
