Dissolution is typically the rate limiting step: low volume of mucous. Abdominal movements may press down on the walls providing for increased dissolution through spreading (upright) Food residues in the higher colon will promote muscle movement of the rectal wall and cause spreading and increase absorption. Tablets that release co2 used to stimulate defecation. Hard to dissolve due to low liquid volume. Apply internally or externally (e. g. steroid for haemorrhoids) Not easy for patient to do alone.
