How Fleet Bisacodyl works

Fleet 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.

Fleet 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. Fleet Bisacodyl decreases expression of aquaporin 3, preventing water from moving into the vasculature, which may contribute to increased water in the colon.

Fleet Bisacodyl directly stimulates parasympathetic nerves in the colon, stimulating contraction of longitudinal smooth muscle but not circular smooth muscle.
