Chemical Composition

Duloxetine Hydrochloride has the chemical formula C18H19NOS·HCl. It is a white to off-white powder that is soluble in water and methanol. The compound belongs to the class of SNRIs, which are characterized by their ability to inhibit the reuptake of serotonin and norepinephrine.
