How ratio-Bisacodyl works
ratio-Bisacodyl is deacetylated to the active bis-(p-hydroxyphenyl)-pyridyl-2-methane (BHPM) by an intestinal deacetylase. BHPM can stimulate parasympathetic nerves in the colon directly to increase motility and secretions.
ratio-Bisacodyl stimulates adenylate cyclase, increasing cyclic AMP, leading to active transport of chloride and bicarbonate out of cells. Sodium ions, potassium ions, and water passively leave the cell; while sodium and chloride ions are unable to be reabsorbed.
Water is also be transported from the luminal side of cells into the vasculature by aquaporin 3. ratio-Bisacodyl decreases expression of aquaporin 3, preventing water from moving into the vasculature, which may contribute to increased water in the colon.
ratio-Bisacodyl directly stimulates parasympathetic nerves in the colon, stimulating contraction of longitudinal smooth muscle but not circular smooth muscle.
