For those who are concerned with their excess weight and looking for effective means to lose fat, you should get more information about these popular medications, their similarities and differences.
Basically, Phentermine and Meridia are central nervous system stimulants and their mechanisms of action are similar. At the same time, these drugs have a number of differences that can affect the therapy effectiveness.
To determine the best weight loss medication for your needs, it’s advisable to make a comparison between Meridia and Phentermine.
You need to understand that Meridia is a brand name for Sibutramine, which is a weight loss drug suppressing appetite and is sold only with a doctor’s prescription. Sibutramine is a potent serotonin inhibitor and was originally developed as an antidepressant. However, antidepressive effect of this drug was turned out to be weak. However, potent anorexigenic effect was noted when taking this drug, so Sibutramine has become available as an agent for obesity treatment. It’s worth mentioning that Meridia is the first serotonin reuptake inhibitor used to lose weight, although other medications of the same class are used as antidepressants.
- Meridia helps obese people control their appetite by inhibiting a serotonin, dopamine and norepinephrine reuptake.
- Besides this, Meridia use increases energy expenditure through thermogenic effects both in the basal and in fed states.
This medication is not for everybody. Your doctor will advise you to avoid this weight loss drug if you suffer from such medical conditions as:
- liver ailments;
- kidney problems;
- uncontrolled hypertension;
- major eating disorder (anorexia or bulimia).
If you are prescribed with Meridia, you still need to monitor your pulse rate, blood pressure and go for medical check-ups on a regular basis.
Phentermine belongs to amphetamines, and it’s a very popular weight loss treatment product these days. However, it’s available only with a prescription and it promotes fat loss by stimulating your central nervous system and suppressing hunger signals in the hypothalamus. Anti-obesity drug stimulates neurons to release a particular group of neurotransmitters (dopamine and norepinephrine) that accelerate the onset of satiety and suppresses appetite.
You should understand that this med is an effective stimulant that boosts the amount of adrenaline in the body. Many obese patients use this therapy to lose fat effectively, but they may experience certain adverse effects in rare cases.
The most common ones include vomiting, headaches, irritability, nausea, insomnia and so on.
Phentermine is contraindicated to patients with:
- coronary artery disease;
- congestive heart failure.
Besides, keep in mind that you’re not allowed to take Phentermine for longer than a few weeks because of developing dependency and serious side effects.
To sum up, Meridia and Phentermine are two different medications that affect your brain in different ways and are used to treat obesity. Both drugs are not recommended during pregnancy and the entire breastfeeding period.
