If I think of the structur and effect of other sigma ligands I would believe that Opipramole isn't a sigma agonist. It is a sigma antagonist!!!

Does anybody know opipramol's affinity for particular receptors (σ1 ,σ2, D2, 5-HT2, H1, H2, mACh) -> Ki=???nM

Bad English or missing words in two sentences?
''Sigma receptors as a set of proteins located in the endoplasmic reticulum, σ1 receptors play key role in potentiating intracellular calcium mobilization thereby acting as sensor or modulator of calcium signalling. Occupancy of σ1 receptors by agonists causes translocation of the receptor from endoplasmic reticulum to peripheral areas (membranes) where the σ1 receptors and neurotransmitter release.''

Both sentences seem to lack a word or use the wrong verb form. At least I don't understand them. For example: "where the σ1 receptors and neurotransmitter release." Release what? Or "are released"?

Why isn't it used in the USA?
Is there a specific reason known, why it isn't on the market in the USA?
