Analysis of Tianeptine in Dietary Supplements

Abstract

In the United States (US), tianeptine is sold as a dietary supplement under the trade name Tianaa™. Tianeptine is a synthetic drug prescribed by physicians as an antidepressant in parts of Europe, Asia and South America. The drug is not permitted for use by physicians in the US, because it is a μ-opioid receptor agonist with a propensity for severe addiction. As the incidence of Tianaa™-related opioid addiction across the southern US escalates, the current study aimed to quantify tianeptine in over-the-counter Tianaa™ White, Red, and Green products. The results of this investigation measured tianeptine levels between 3.1 and 10.9 mg per 531 mg capsules. Tianaa™ White capsules consistently contained the least tianeptine, while Green had the most. The close inspection of Tianaa™ products showed that capsule mass varied by as much as 16% from label claim, and the amount of tianeptine per capsule varied by as much as 35% from the average measured amount for each product. Tianaa™ Red contains kava leaf extract, which led to the identification of four kavapyrone components by mass spectrometry. The data presented provide insight into tianeptine quantity and capsule mass variation for Tianaa™ supplements sold to customers naive to the risk of addiction.
