>>87912664Desvenlafaxine is derived from Venlafaxine. It's a synthetic form of the major active part of Venlafaxine; when you take Venlafaxine, 70% of it is metabolized as Desvenlafaxine (and 20% of that 70% is lost in urine excretion).
That's why they're named so similarly; one (Venlafaxine) is turned into the other (Desvenlafaxine) by your metabolism, but can be synthetically produced as the final product, upping the efficacy and effectively cutting out waste (but increasing risks of heart problems instead).
