Influence of sympathomimetic amine Phentermine on functions of cardiovascular system

Given that sympathomimetic amine Phentermine stimulates noradrenergic and dopaminergic CNS receptors, it is able to change peripheral and local hemodynamic profile. Influencing on several types of noradrenaline and dopamine receptors at once, sympathomimetic amine Phentermine can cause peripheral vasodilation and thereby increase:

• myocardial contractility;
• heart rate;
• total vascular resistance;
• stroke volume and cardiac output.

Acceleration of the heart rate is very often accompanied by tachyarrhythmia and the increase in myocardial oxygen demand. It should be noted that the daily use of high Phentermine doses increases the likelihood of cardiovascular side effects.

Phentermine and causes of tolerance development to anorexigenic effect

Patients taking Phentermine tablets should remember that this drug is prescribed for short-term obesity treatment only. In prolonged use of Phentermine drug (regardless of daily dosage), tolerance to anorexigenic activity of this drug develops in patients.

• Topiramate was approved by the FDA for the treatment of epileptic attacks and prevention of migraine.

Feasibility of combined use of Phentermine and Topiramate is proven by the fact that Topiramate has anorexigenic effect just as Phentermine. Therefore Topiramate increases pharmacological action of Phentermine, allowing to reduce the dose of Phentermine twice.

It should be noted though that Topiramate possesses slight anorexigenic effect and even maximal Topiramate doses provide no significant effect. Hence, Topiramate cannot be prescribed for monotherapy of obesity and can be only used in combination with Phentermine.

Phentermine efficiency

Using just one Phentermine pill can help to lose weight, as well as significantly reduce the risk of related diseases. For example, only 5% of weight loss (compared to initial) reduces the risk of diabetes significantly.

The fact is that Phentermine stimulates almost all parts of the brain, making human body to intensively waste the energy and mental resources. These changes occur due to the fact that Phentermine releases a large amount of epinephrine, norepinephrine and dopamine.

The release of large amount of epinephrine, norepinephrine and dopamine can cause: high blood pressure and (or) intracranial pressure; develop cardiac arrhythmia, enhanced cerebral circulation and increased heart rate.

That’s why Phentermine increases the risk of irreversible disorders in cardiovascular system, when used in heart disease.
