Phentermine’s History

Phentermine was first approved by the FDA for use as an appetite suppressant in 1959, following a series of successful tests on rats. It entered the market in its current form, as Phentermine hydrochloride, and became available in the 1970s for personal use.

Since the drugs approval in 1959 no clinical studies have been conducted to test the various long term effects of Phentermine. In 1990, Phentermine was combined with Fenfluramine and became known as Fen-Phen. Fen-Phen was never approved by the FDA, though various clinical studies were published. The general consensus was that Fen-Phen was more effective than Phentermine and had fewer side effects. However, Fen-Phen was voluntarily removed from the market at the request of the FDA when it was discovered that nearly 30% of the people taking Fen-Phen had abnormal heart valve findings.

Phentermine is well known throughout the diet supplement industry as it is one of the oldest and most established ingredients in the industry. New appetite suppression methods, such as Hoodia Gordonii, are showing to be just as effective as Phentermine without the negative side effects.

Phentermine vs Adipex: Know the difference?

From ages, exercises and controlled diet program are considered as some of the best techniques to lose weight. But, contemporary fast pace of life doesn’t allow these proven but slow methods. Though advance medical sciences have also given many other quick and effective options, like liposuction and surgery, but again the heavy cost and repetitiveness have prevented many to opt for these methods.

Medical science has been looking for a superior, cheap & effective solution, which can help a person get rid of obesity. After many tests, failures & successes, some development has been seen in the formulation of weight loss drugs. Phentermine, Adipex, Xenical & Ionamin are few of the famous branded diet pills manufactured by different companies but they all have same property as of Phentermine.

In 1959, FDA (Food and Drug Administration) approved Phentermine, which was initially made available in US in the resin form. But later in the early 70’s, Phentermine Hydrochloride entered the market. Point of fact is that there is no difference between Phentermine and Adipex. Phentermine is the generic name of this weight loss drug and Adipex is the brand name of Phentermine, which is manufactured by Gate Pharmaceuticals. The online availability of these weight loss drugs have eased people as getting the medicine takes only few second rather than going to the market. Good news is that online drug stores offer cheaper Adipex & Phentermine than local physical drug stores.

Like Phentermine diet pills only, Adipex diet pills are also sympathomimetic amine. This compound is similar to amphetamine and prescribed as a short-term supplement to regular workouts and controlled as well as balanced diet programs for treating obesity. If, simply said, both Phentermine & Adipex are appetite suppressants and works by affecting central nervous system. As the body gets a “full” feeling resulting from the effects of suppressed appetite, automatically the food intake is reduced. And when the body calls for energy to perform normal functioning, it starts breaking down the fat mounted up on the body thereby making an obese person lose his extra weight.

Although Adipex & Phentermine, both are considered as safe weight loss drugs, but consultation with a physician is a must before seeking medication for any of these weight reduction drugs. Pregnant women, breast feeding mothers, person with hypertension, heart problems, glaucoma, history of drug or alcohol abuse, diabetes, epilepsy, allergy etc. should discuss with their doctor properly before taking Adipex or Phentermine.

The early phase of taking the drug may be associated with mild side effects like blurred vision, touchiness, bad stomach, and dry mouth. It can also increase heart rate and blood pressure. Normally, the normal dose includes a pill a day with water but other ways may be prescribed by doctors. So, one should always follow the instructions given by the doctor.

In the last, one should be informed that both Phentermine and Adipex are short term weight loss drugs and not a permanent way out to reduce obesity. Additionally, they are also found to be habit forming. So, to get rid of obesity permanently one has to abide by a strict diet program and regular physical activities along with medication.
