Although there are a plethora of brown fat good or bad (More) burning drugs on the market, they’re however mostly classified as being either prescription or even non-prescription based. The prescription weight loss drugs, also called ethical drugs, are medications which have been authorized by the FDA and which will only be bought from the acceptance of a health care professional.
Likewise, the various FDA approved prescription weight loss drugs can be further categorized into two groups that are different based on the specific duration of theirs of use – i.e. being either short- or long-term. This kind of article takes a look at the presently FDA approved short-term weight loss drugs and coincidentally, they all eventually be appetite suppressing medications.
Appetite suppressing medicines work by either decreasing appetite or boosting the sensation of fullness. They typically work on the essential concept of manipulating the hypothalamus – the appetite control center of the brain – by increasing one or perhaps more brain chemicals which modulate appetite and mood.
The approved appetite suppressing drugs should be to a group of medications known as phenethylamines – somewhat similar to amphetamines. Amphetamines are any of a team of powerful stimulant medications which act on the main nervous system and which normally triggers increased amount of heart rate, blood pressure, and energy. Regardless of the fact that phenethylamines are chemically similar to amphetamines, they however have a significantly reduced incidence of the side effects associated with amphetamines.
The FDA-approved appetite suppressing medications affect the central nervous system through a number of different active ingredients as well as modulation mechanisms. These appetite suppressing medications can be split into three major active component groups as follows:
Phentermine
These are possibly the most popular short term prescription based weight loss drugs today. Phentermine based appetite suppressants were initially approved in 1959 and especially to be used for short term treatment of obesity, in most cases not longer than 6 months.
The principal active ingredient used in Phentermine is Phentermine hydrochloride which in turn promotes a team of neurotransmitters recognized as catecholamine like epinephrine (also also known as adrenaline), dopamine, and norepinephrine. Phentermine hydrochloride impacts the main nervous system by triggering a « fight or perhaps flight » state within the body.
This condition is typically believed to result in the brain not to receive the hunger signals the stomach may be sending to it because of the concentration of its on the way to respond to the immediate as well as more serious demand for energy caused by the « fight or perhaps flight » signal.
