In the mid-'90s, the diet pill industry was booming. In 1996,
more than 18 million obese people in the United States were
taking appetite suppressants like Fenfluramine (or dexfenfluramine)
and Phentermine, nicknamed fen-phen. But doctors found that
healthy patients who were taking fen-phen developed a potentially
fatal heart disease. In September 1997, the FDA announced
that it was withdrawing the "fen" drugs from the
market because of their link to heart problems. Phentermine
diet pill is still available on its own.
Diet pills have become a lucrative business all around the
world. Pharmaceutical companies are now pushing to introduce
more products to the market. More than 70 weight loss medications
are either in development or in clinical trials.
Many prescription drugs are used as diet aids even though
that was not their intended purpose. Some anti depressants
are used off-label as diet aids because they have been shown
in studies to help patients lose weight and keep it off for
several months.
Different diet pills work in different ways.
Appetite
suppressants such as sibutramine (Meridia), diethyl propion
(Tenuate) and Phentermine
(Adipex) affect the appetite regulating region of the brain
called the hypothalamus. They work by changing the levels
of the chemical serotonin and nor epinephrine and create the
feeling of satiety and thus one feels full and eats less.
It is speculated that this action, along with as yet undetermined
effects on the metabolism are responsible for the loss of
appetite seen with this class of drugs. Phentermine diet pill
can be appropriate for an individual who's eating habits or
behavior alone is responsible for excessive weight gain. Research
into the effectiveness of Phentermine diet pills shows an
average weight loss of 2-8 kg more than placebo for the same
duration of treatment.
It is important to remember that Phentermine diet pill is
only approved for short-term use, and it doesn't seem to work
for everyone.
Phentermine diet pills and its brand names are widely available
on internet pharmacies. One can take Phentermine from any
of medical store and one might even get Phentermine as compared
to the drug store. Most of the Phentermine online are produced
of relatively familiar ingredients. And one can get Phentermine
on these sites. Phentermine diet pill pharmacies are in a
plenty. One must be extremely careful while buying these prescription
drugs online.
Most of these
prescriptions diet pills can only be prescribed to severely
obese patients with a very high BMI as the medications also
have serious side effects that make them unsuitable for many.
A medical intervention in obesity starts with diet therapy
for four weeks along with an appropriate exercise regime.
If this fails to achieve an average weight loss of 0.5kg/week
(approximately 1 pound/week) then drug therapy may be recommended.
However, underlying hormonal or metabolic diseases should
be ruled out prior to initiation of drug therapy.
