Phentermine and Topiramate

Qsymia (Phentermine and Topiramate)

July 17, 2012 the FDA approved a new drug Qsymia for obesity treatment. The new drug Qsymia for obesity treatment consists of two pharmacological substances Phentermine and Topiramate.

  • Phentermine was approved by the FDA for short therapy of exogenous obesity.
  • Topiramate was approved by the FDA for the treatment of epileptic attacks and prevention of migraine.

Feasibility of combined use of Phentermine and Topiramate is proven by the fact that Topiramate has anorexigenic effect just as Phentermine. Therefore Topiramate increases pharmacological action of Phentermine, allowing to reduce the dose of Phentermine twice.

It should be noted though that Topiramate possesses slight anorexigenic effect and even maximal Topiramate doses provide no significant effect. Hence, Topiramate cannot be prescribed for monotherapy of obesity and can be only used in combination with Phentermine.

Low doses of PPP in Qsymia anti-obesity drug helps to minimize the risk of side effects. But because of the lack of information on post-marketing trials, Qsymia anti-obesity drug (Topiramate, Phentermine) is not so popular in clinical practice so far.

According to results of those clinical trials, after a year of regular use of Qsymia in minimal dose (Phentermine 7.5mg and Topiramate 46mg), patients managed to lose up to 10% of their initial weight.

It was also proven that if 12 week after the daily use of Qsymia weight loss pills, the weight loss is at least 3% of the initial, it is no longer necessary to take Qsymia pills.

The FDA obliged the manufacturers of Qsymia slimming pills (Vivus, Inc. Company) to spend 10 years for marketing studies. In addition, the company was obliged to study impact of a long-term use of Qsymia weight loss pills (Phentermine and Topiramate) on the cardiovascular system.

Such decision of the FDA was based on the fact that long-term use of Phentermine medication (even in minimal doses) increases the risk of dysfunction in the cardiovascular system.
