HOW DO SEROTONIN 5-HT2C RECEPTOR AGONISTS WORK?

Serotonin 5-HT2C receptor agonists are a class of drugs mainly prescribed for weight loss in adjunct to calorie-restricted diet and exercise.

5-HT2C receptors are mainly found in the hypothalamus region of the brain. It is one of the many binding sites for the neurohormone serotonin. Activation of 5-HT2C receptors by serotonin inhibits dopamine and norepinephrine release in particular areas of the brain and thus regulates:

  • Mood
  • Anxiety
  • Feeding
  • Reproductive behavior

Stimulation of 5-HT2C receptors can promote early satiety and reduction in food consumption. Hence, by selectively activating 5-HT2C receptors, serotonin 5-HT2C receptor agonists facilitate weight loss in obese people.
