Our expert says:
Lexamil is a generic ( equivlent but cheaper ) version of the idenical active drug as is in Citalopram. So it ought to be equally effective. But the doses should be equivalent, thus at 20 Lexamil, someone has increased your dose for some reason.
Like you and I, Serotonin is versatile, and has varying effects depending on where in the brain it is being active. But the answer to the apparent mystery is simple --- Lexamil and all the other SSRI drugs ( Przac having been the first of the family ) inhibit Serotonin RE-UPTAKE in the brain --- in other words, after serotonin is released to do its work, if you are relatively lacking in it, these drugs slow the process by which the serotonin is absorbed back into the nerves, allowing what there is to act for a bit longer, maki ng up for the relative lack of it. Thus giving you effectively more serotonin bang for the buck.
