Overview of Dirlotapide (Slentrol™) for Dogs

  • Dirlotapide, commonly known as Slentrol™, is a drug approved by the FDA for canine obesity. It is also called “Slentrol”. Obesity is defined as the excessive accumulation of body fat.
  • Canine obesity is an important medical condition with serious health implications. Dogs that are overweight may experience difficulty breathing or walking or they may be unable to tolerate exercise or heat. For more information on obesity, go to Canine Obesity.

  • Dirlotapide is a chemical entity called a selective microsomal triglyceride transfer protein inhibitor that acts to block the assembly and release of lipoproteins into the bloodstream. The mechanism for producing weight loss is not completely understood, but seems to result from reduced fat absorption and a satiety signal from lipid-filled cells lining the intestine.
