The most common antidepressants prescribed today come under a class of neuroactive drugs called 'selective serotonin reuptake inhibitors', or SSRIs for short. These include: Citalopram (Celexa), Fluoxetine (Prozac), Fluvoxamine (Luvox), Paroxetine (Paxil), Sertraline (Zoloft) and Venlafaxine (Effexor).
The primary mechanism of action for SSRIs to modify the way serotonin gets taken back up at the synapse. Not all SSRIs work on boosting serotonin levels though. Some like Venlafaxine also increase the amount of noradrenaline available at the synapse.
Older antidepressants like Clomipramine (Anafranil), referred to as 'trycyclic antidepressants', work primarily by inhibiting the reuptake of noradrenaline; although like some SSRIs, their selectively is never absolute, so they also have some effect on serotonin and dopamine reuptake too.
Atypical depressants like Bupropion (Wellbutrin) and monoamine oxidase inhibitors like Phenelzine (Nardil) also exert their effects via manipulating serotonin/noradreneline/dopamine levels.
Although each class differs subtly in their mechanism of action and specificity, they all essentially work to boost biogenic amine levels in the brain (i.e., serotonin and/or dopamaine and/or noradrenaline).
And then there is something like 5-HTP which is more effective then any of the SSRI's or Trycyclic antidepressants for the simple reason that 5-HTP actually helps to create more serotonine (5-HTP is the direct precursor for serotonine).

What is a good antidepressent?
There are many excellent antidepressants, many of the best are in the class of SSRI antidepressants because they have fewer and less severe side effects than older types (e.g. MAOI antidepressants, tricyclic antidepressants).However what works for one person does not for another, so you and your psychiatrist may have to try several before finding a good antidepressant for you.
How does the synapse work between each neuron?
There are many kinds of synapses in the nervous system, but I assume you're talking about the most commonly discussed type: the chemical synapse. These synapses join nerve cells (called neurons) and allow them to communicate.Communication across a chemical synapse is called synaptic transmission. It occurs when electrical activity (called an action potential) in the first cell triggers the release of a chemical signal (called a neurotransmitter) across the synapse. The neurotransmitter travels across the synapse by a process of diffusion, ultimately reaching its target, the second cell. There, the neurotransmitter binds a special type of protein molecule called a neurotransmitter receptor, which changes its shape in response to binding the neurotransmitter. This shape change results in a series of subsequent changes in the second cell. These subsequent changes result in alterations in the electrical activity of the second cell.The gist of synaptic transmission is that it allows the electrical activity in one nerve cell to influence the electrical activity of another.
What is the average lag period for antidepressants to begin effective?
It depends on the type of anti depressands.Short acting antidepressants starts acting within minutes.But most of the antidepressants used in chronic depression may take many hours to days for optimum action.
What specific neurotransmitter is released from the axon terminus?
The specific neurotransmitter released from the axon terminus depends on the type of neuron and the location in the nervous system. Common neurotransmitters include dopamine, serotonin, acetylcholine, and glutamate.

What element forms the antidepressants?
There are many examples of antidepressants and each can have different elements, all of which cannot be listed. However, all antidepressants are generally organic compounds and they normally contain carbon, hydrogen, nitrogen and oxygen. some may contain halogens, sulfur, phosphorus, etc.
What disease has a neurotransmitter problem?
Neurotransmitter problem can be involved in many neurological diseases. One example is Parkinson disease which is the brain's inability to produce sufficient amounts of dopamine.
