In dietetics, various pharmaceuticals have long been used that normalize metabolism and speed up the process of losing extra pounds. One of them is Phentermine. This drug is an amphetamine derivative and, accordingly, has psychostimulating and sympathomimetic properties.

Mechanism of action

The drug has a stimulating effect on the central nervous system, and enhances the synthesis of neurotransmitters. As a result, the nature of the transmission of electrochemical impulses between neurons changes. And they simply do not reach the "hunger" center in the cerebral cortex. Therefore, a person does not feel the desire to eat.

But the body needs energy to maintain life and movement. Not receiving it from outside with food triggers lipolysis - the breakdown of adipose tissue. This explains the therapeutic effect.

According to the World Gastroenterological Association, obesity therapy with Phentermine promotes rapid weight loss in more than 60% of patients. Kilograms "burn" faster in people who not only take pills but also adhere to a low-calorie diet and exercise.

Indications

According to the instructions, Phentermine is prescribed to people whose body mass index exceeds 30 kg / m2. If a person has concomitant diseases or a high risk of their development (endocrine, cardiovascular pathology), then it is permissible to include pills in the course of complex therapy and with a lower BMI.

It is known that sometimes bodybuilders and weightlifters resort to using pills who want to quickly lose weight but at the same time maintain physical activity at the same high level. This is illegal, if the anti-doping commission reveals this fact, the athlete will be disqualified.

The course of treatment for obesity with "Phentermine" should not last more than 10-12 days.

Side effects

Like any amphetamine derivative, this drug can lead to a number of undesirable consequences:

• increased blood pressure;
• irritability, aggressiveness;
• insomnia;
• disturbances in skin sensitivity;
• dehydration;
• increased heart rate;
• constipation.

Due to their high probability of developing side effects, many experts in the field of dietetics have repeatedly raised the issue of a complete ban on Phentermine. The appearance of any of the listed symptoms is a good reason to stop therapy.

Contraindications

Slimming pills should not be prescribed to patients who suffer from cardiovascular diseases and, above all, arterial hypertension. With special caution, they can be used in the treatment of people with anxiety-depressive disorders, as they can provoke a sharp deterioration in mental state.

Phentermine is prohibited for use in the treatment of patients with a history of alcohol, drug, or medication addiction.

Overdose

Over time, tolerance develops to any amphetamine derivative, that is, therapeutic doses cease to have the desired effect. And people begin to gradually increase them. As a result, sooner or later an overdose occurs - acute poisoning with the drug.

This condition is characterized by the following symptoms:

• psychomotor agitation:
• delusions, persecution mania, paranoia;
• hallucinatory psychosis;
• severe abdominal pain;
• nausea, vomiting;
• dilated pupils;
• cardiac arrhythmias;
• a sharp increase in blood pressure;
• hyperthermia;
• acute urinary retention.

At the same time, the patient retains memory, orientation in time and space. If symptoms of amphetamine intoxication appear, the patient must immediately call a doctor.

Although Phentermine does not cause pronounced euphoria, that is, it has a weak narcotic effect, its long-term use still leads to the formation of a painful addiction.
