Mechanisms by which drugs do they act?

Mechanisms by which drugs do they act?

The drugs act on neurotransmitters, disrupting their operation:

- Taking their place in the receivers because their structure is close. For example, morphine binds to endorphin receptors, nicotine on nicotinic acetylcholine receptors. Over time, if drug use is regular, the natural production of neurotransmitters is reduced in response to these phenomena, and the lack of physical sensation appears.

- Helping to increase production, such as cocaine, which increases the secretion of dopamine, or ecstasy for the production of dopamine and serotonin. This leads to reduced sensitivity of receptors to these products because they are quickly "saturated": the higher doses is needed to achieve the same effect.
- By blocking the receptors for some neurotransmitters, in the case of alcohol, for example

And the dopamine reward circuit

Thus, the brain areas involved have their operation modified, because the signals they receive are not the same.

The effects of the drug depend on the area of the brain involved, because it is sensitive to the neurotransmitter target and the nature of the disturbance it causes.

This reaction involves the stimulation of this system, the origin of a reward circuit that causes sensations of pleasure and well-being.

The neurotransmitter and will bind to specific receptors on the cell membrane of the receiving neuron, which in turn will by the same mechanisms, the propagation of nerve impulses.
