Tianeptine Ethyl Ester Sulfate is an improved salt of Tianeptine. It is not hygroscopic so handling the powder is a lot easier. Since it is not as readily absorbed and excreted from the body, the sulfate salt allows for a more controlled release of the Tianeptine over longer periods. Rather than having to dose three times with rapid peak effects and rapidly falling effects, the sulfate salt allows for one dose to maintain plasma levels in the body much longer than the sodium salt. These improved characteristics make Tianeptine Sulfate a novel addition.
