Analysis of Imitrex® API from Tablet Formulations

This AppNote Method for Analysis of a challenging compound (Sumatriptan) has several advantages over other Methods. This Analysis can be performed using a higher concentration of organic solvent, which is much more suitable for electrospray MS Detection.

This AppNote provides robust and repeatable (%RSD 0.1 and lower) results.

Sample Preparation: Six 25mg strength tablets of Imitrex® were crushed and a portion containing 40mg of the API was weighed out. The powder was suspended in an Solvent A / Solvent B (1:1) Mixture, vortexed, and filtered through a 0.45μm Syringe Filter (MicroSolv Tech Corp.). A Sample for injection was diluted to final concentration of 0.0005 μg / mL.
t0: 0.9 minutes

Note: Migraine is a common disorder, with symptoms of unilateral headache accompanied by nausea and / or vomiting. Sumatriptan is an anti-migraine drug sold under the trade name Imitrex®. It belongs to a class of drugs called Selective Serotonin Receptor Agonists.
