Lorcaserin
   

     Lorcaserin is the generic name (at the time of this writing there was no brand name associated with it) of a trial weight loss medication produced by Arena Pharmaceuticals.Lorcaserin is classified as an appetite suppressant. In essence, it works in the brain to make one feel full. It works by stimulating parts of the 5-HT2C serotonin receptor in the hypothalamus thus affecting appetite and metabolism. It has a similar make up to a banded drug Phen-Fen but Phen-Fen was not selective in its workings and unlike Phen-Fen, Lorcaserin is
not showing the negative properties that got Phen-Fen banned. Phen-Fen was a combination drug consisting of Phentermine and Fenfluramine. Phentermine is still used today but it was the Fenfluramine part that was shown to cause pulmonary hypertension and heart value problems that proved to be dangerous and sometimes fatal.  
     Lorcaserin has been through several clinical tests now that show it could be a good candidate for FDA approval. Just under 500 overweight men and woman were signed up to be patients over 12 weeks. During this time doctors studied various aspects of their health for overall effectiveness and safety. There where 4 different amounts given to various people, 10mg, 15mg, 20mg or nothing (placebo was given) And what was shown was each dose produced a average different result in weight loss. Cholesterol levels also improved and blood pressure remained steady. And no heart value issues where reported like where showing years ago with Phen-Fen.
     Some side effects reported and these where nausea, headache, dry mouth, dizziness, fatigue, vomiting, and urinary tract infections,  but generally well tolerated. A stage 3 trial conducted for a period of over a year later showed that patients lost an average of 8% of their body weight, which falls within the FDA guidelines for an effective obesity medication.
