hello everyone, i just wanted to ask which drugs increase the serotonin effect in the brain? and which drugs combined increase the effect of serotonin? I know that ssri works on serotonin but i've also red that maoi's combined with ssri's can actually work better than if you only take one ssri. finally do you know which combination of drugs are better for treatment resistant depression? i have tried many antidepressants combined with citalopram but no one works...
