Diet Pills & Meridia
Here we attempt to explain the differences between the different types of diet pills and weight loss drugs that are available by prescription. There are essentially 3 different kinds of weight loss actions employed by the different diet pills:
- Sympathomimetic family of appetite suppressants - stimulates the central nervous system (nerves and brain), which increases your heart rate and blood pressure and decreases your appetite.
- Stomach lipase inhibitor (a fat blocker) - works in your digestive system to block about one-third of the fat in the food you eat from being digested. Enzymes in your digestive system, called lipases, help digest (or break down) fat.
- Sibutramine - Balances two very important brain chemicals, serotonin and
norepinephrine. This helps to increase metabolism and causes a feeling of fullness and increased energy levels. Studies indicate that sibutramine assists in both weight loss and management.
It is important to read the information on this page together with the drug information provided for each of the different diet pills to ensure that you understand all the possible side effects of each drug and that you fully understand the difference between each weight loss drug.

Notable Differences
(Difference between the diet pills)
|
| Phentermine |
Phentermine Hydrochloride (HCL) |
Sympathomimetic family of appetite suppressants |
Phentermine is the cheapest of the prescription diet pills. It is indicated to work for up to 3 months at which point the body builds up a resistance. Therefore it is useful for a quick start.
|
| Meridia |
Sibutramine |
Affects appetite control centers in the brain. Reduces food intake by increasing satiety. Not an appetite suppressant |
Meridia balances two very important brain chemicals, serotonin and norepinephrine. This helps to increase metabolism and causes a feeling of fullness and increased energy levels. Studies indicate that sibutramine assists in both weight loss and management in the longer term. It is approved for continuous use for up to two years, however studies have shown up to 1 year to be optimal.
|
| Xenical |
Orlistat |
Stomach lipase inhibitor (a fat blocker) |
Unlike other commonly prescribed weight-loss medications, Xenical is not an appetite suppressant and does not have a direct effect on the brain. Instead, it works in your digestive system to block about one-third of the fat in the food you eat from being digested. Enzymes in your digestive system, called lipases, help digest (or break down) fat. When taken with meals, Xenical attaches to the lipases and blocks them from breaking down some of the fat you have eaten. The undigested fat cannot be absorbed and is eliminated in your
bowel movements. |
