5 Pharmacology and Biochemistry
5.1 MeSH Pharmacological Classification

Anti-Obesity Agents

Agents that increase energy expenditure and weight loss by neural and metabolic regulation. (See all compounds classified as Anti-Obesity Agents.)


Enzyme Inhibitors

Compounds or agents that combine with an enzyme in such a manner as to prevent the normal substrate-enzyme combination and the catalytic reaction. (See all compounds classified as Enzyme Inhibitors.)


Lipid Regulating Agents

Substances that alter the metabolism of LIPIDS. (See all compounds classified as Lipid Regulating Agents.)


5.2 Mechanism of Action

Cetilistat is a gastrointestinal lipase inhibitor that blocks fat digestion and absorption, leading to reduced energy intake, and thus weight loss. It is distinct from most other anti-obesity agents as it does not act on the brain to reduce appetite, but acts peripherally. The compound remains in the gastrointestinal tract with no significant absorption into the body.
