Phentermine/topiramate
Phentermine/Topiramate is a prescription medication used for weight loss. It is a combination of two medications, phentermine and topiramate, that work together to help suppress appetite, increase metabolism, and promote weight loss.
Popularity
One of the most popular and most effective weight loss medication as the combination effectively blocks both the appetite and cravings in most people and studies have shown it to lead to about 10% weight loss in a year, more than twice as much as the competition such as 4.5% percent weight loss expected with Belviq, or 5% weight loss expected with the new Contrave. Phentermine-topiramate (Qsymia) was approved by the US FDA in July 2012 (Qsymia)
Mechanism of action
Phentermine is a sympathomimetic amine and works as an appetite suppressant by stimulating the release of norepinephrine in the brain, which signals the body to reduce hunger. Topiramate is an anticonvulsant medication that has been shown to promote weight loss by increasing feelings of fullness and reducing the desire to eat.
Weight loss results
Together, phentermine and topiramate can help people with obesity to achieve significant weight loss. Clinical trials have shown that patients taking phentermine/topiramate for a year can lose an average of 10% of their body weight.
Improved metabolic health
In addition to promoting weight loss, phentermine/topiramate has been shown to improve several markers of metabolic health, such as blood pressure, blood sugar, and cholesterol levels. This makes it a potentially effective treatment option for people with obesity-related health conditions such as type 2 diabetes, hypertension, and dyslipidemia.
Contraindications
It is important to note that phentermine/topiramate is not suitable for everyone. It is contraindicated for people who have glaucoma, hyperthyroidism, a history of heart disease or stroke, or who are pregnant or breastfeeding. Like all prescription weight loss medications, it should only be used under the supervision of a qualified healthcare provider.
