| The blocking ratio indicates the relative effect of the agent on reuptake of serotonin vs. noradrenaline. Fluoxetine is 3 times more selective for serotonin than clomipramine. Clomipramine was the first TCA whose ratio favours serotonin reuptake inhibition, and hence its title of non-selective serotonin reuptake inhibitor (SRI). The level of anticholinergic effect is usually also decreased with increasing serotonergic selectivity. | | The blocking ratio indicates the relative effect of the agent on reuptake of serotonin vs. noradrenaline.
