Mechanism of action

Quinine activates bitter taste receptors (TAS2Rs) located on enteroendocrine cells in the duodenum, triggering the release of incretin hormones and other metabolic regulators. This localized intestinal stimulation enhances glucose-dependent insulin secretion and improves postprandial glucose control without systemic absorption of the drug.
