Your brain has four (4) main neurotransmitters that can cause depression. Without getting to technical, neurotransmitters are chemicals in the brain that transmit nerve impulses in the brain. If these chemicals are out of balance then the nerve impulses won't transmit correctly leading to a depressed state.
The transmitters are called dopamine, norepinephrine, serotonin and monoamine oxidase or MAO. Each of these transmitters effect different parts of the brain as follows:
Dopamine is linked directly to feelings of pleasure and self-stimulation
Norepinephrine is linked to incoming stimuli, altertness and energy levels
Seratonin balances the dopamine and norepinephrine and directly influences mood
MAO breaks down adrenaline and serotonin
So, what medications do is inhibit the activity of the MAO and/or increases the levels of adrenaline, serotonin, norepinephrine and dopamine. The result is a decreased feeling of depression, an increased level of energy and a better mood.
