Diet pills are drugs that are taken to help a person in losing some weight. There are many types of weight loss pills that are available in the market these days. Among the most prominent types are the appetite suppressants. These drugs help us lose our weight by suppressing the appetite. They work by altering the level of chemicals in the brain that is associated with the signal or the feeling that you are full.
Other types of diet drugs work by increasing the body’s metabolism. These are known as fat burners. These pills help a person lose weight by increasing the body’s ability to burn a significant amount of fat that will be used as energy for the body. Last but not the least, there are weight loss pills that work by decreasing the body’s capability to absorb fat and cholesterol. These are known as fat or carb blockers. They limit the amount of fat that is absorbed by the body.
The Food and Drug Administration (FDA) Approval
The Food and Drug Administration is in charge of assessing the accuracy and the veracity of the labeling of foods, drugs, and medical devices. They are also responsible for examining the content of the medications. Basically, the FDA can take law enforcement and other legal actions to seize and prohibit the sale of medical products that are not properly labeled.
In the case of diet pills, the Food and Drug Administration (FDA) has approved only selected medications that a health service provider can prescribe to treat obesity or to encourage weight loss. The first of which is the Phentermine. This drug received the FDA approval in the year 1959. It is a prescription appetite suppressant that is often given as a short term treatment of obesity. In 1970, Phentermine Hydrochloride then became widely available in United States.
Twenty seven years after, another appetite suppressant was approved by the FDA. It was Meridia. Just like the Phentermine, this drug works as an appetite suppressant manipulating the neurotransmitters (chemical messengers) in the brain. However, in contrast to the functions of the other diet pills, the Meridia does not increase the release of these neurotransmitters. Instead, the Meridia diet pills restrain the reuptake of these neurotransmitters.
In 1999, another form of diet pills received approval from the FDA. Xenical was approved as a prescription drug for weight loss. Unlike the first FDA approved prescription weight loss pill, this pill works within the gastrointestinal tract. It blocks as much as 30% of dietary fat that we consume. Based on present researches, Xenical is a useful weight loss tool for some obese people, provided that the medication intake is complemented with the right diet and exercise.
In addition to the prescription weight loss pills, an over the counter drug recently received the FDA approval. The first non prescription drug that was approved by the FDA is the Alli diet pills. These pills are also appetite suppressants.
Despite the fact that these pills are approved by the FDA, it should be noted that these will only be very effective in your weight loss management program if you follow the declared guidelines in using these medications. Moreover, it should be noted that the efficiency of these products will only be maximized if proper diet and exercise is implemented as well.
