How it works

This product’s leaflet is published as a scanned document. This section quotes the US prescribing label for the same active substance (venlafaxine hydrochloride). It describes the substance, not this Bulgarian product — its uses and doses can differ.

The mechanism of action of venlafaxine in the treatment of MDD, GAD, SAD, and PD is unclear, but is thought to be related to the potentiation of serotonin and norepinephrine in the central nervous system, through inhibition of their reuptake.

How the body breaks it down

Following absorption, venlafaxine undergoes extensive presystemic metabolism in the liver, primarily to ODV, but also to N-desmethylvenlafaxine, N,O-didesmethylvenlafaxine, and other minor metabolites.
