Scientists said they have discovered the effects of a previously unknown offenders to a drug currently used in the treatment of hypertension, indicating that these effects may have a positive impact in fact useful in the treatment of addictions, especially getting used to the drug cocaine.

 According to a study that scientists have reached this conclusion based on the test included a group of mice that led to addiction to cocaine, and then underwent treatment with a drug "propranolol".

The test to give cocaine to rats at a certain angle from the cage on a regular basis, and show signs of addiction by deliberately mice do all it can to get to that corner in time to dose.

Thereafter, these mice were given injections "propranolol" minutes before the time of access to cocaine dose, and the result was that the rush to get to the corner devoted to satisfying her addiction dropped significantly.

However, the scientists said that the study is still in need of more depth the cause of the decline in Hamas mice about the drug, and whether this is linked to a decline desire pleasure drugs or affected by the memory is prevented from alert to the angle associated with the pleasure of the drug, or for other reasons are still unclear.

When dealing cocaine addict feels:

- Ecstatic and lightness and a sense of high self-esteem up to a sense of greatness.

- Frequent movement.
- Much talk and laugh no matter how they feel distressed.
- Notes by insomnia.
- Pupil dilation.
- Loss of appetite.
- Heart rate with high blood pressure.
- Lack of feeling tired.
- What we find is always sure of himself in an exaggerated manner.

In the case of increasing doses of dealing the overdose cause of addicts in a state of agitation, nervousness, aggression tends addict to abuse others, and loses proper appreciation of the attitudes and his judgment, and it becomes a lot of movement and much talk and laughter too intensely, and he spoke the symptoms of severe mental such as hallucinations, hearing and feeling persecution.

Cocaine lasts between 20 and 45 minutes after the addict to become irritable, feel Palanahtat, which leads to re-using.

University of California scientists found that preventing the activity of hormone-linked sense of hunger may lead to treat cocaine addiction.

And scientists have discovered that the hormone (melanin-concentrating hormone) works with (dopamine) centers of the brain of happiness and fun to create a response to a cocaine addiction and to prevent its activity leads to the urge to identify and therefore treat cocaine addiction.

And scientists believe that the hormone (MCH) work area (nucleus accumbens) the brain to increase the feeling of pleasure when eating, and that when increasing the level of the hormone (MCH) also increases brain dopamine signals.

And scientists conducted tests on mice with cocaine addiction, where they discovered the high level of hormone (MCH) and dopamine that at preventing activity (MCH), the symptoms of addiction ends at the increased level of hormone (MCH) also increases brain dopamine signals.

And scientists say that this discovery will help treat cocaine addiction may also help treat addiction to some other compounds such as (amphetamines) and (nicotine).
