Sur-q-lax
Sur-q-lax Uses, Dosage, Side Effects, Food Interaction and all others data.
Sur-q-lax acts primarily by increasing the penetration of fluid into the faeces. It may also have effects on intestinal fluid secretion, and probably act both as stimulant and faecal softening agent. It also softens ear wax through penetration into the dry matrix of the ceruminous mass, reducing it into semi-solid debris.
Sur-q-lax sodium is a laxative and an anionic detergent that supposedly promotes incorporation of water and fats into stool through a reduction in surface tension, resulting in softer fecal mass . Sur-q-lax's onset of action is 6-72 hours orally and 2-15 minutes rectally . The effects of docusate are thought to be exerted locally in the jejunum.

How Sur-q-lax works
Recent studies suggest that docusate's mechanism of action is due largely to it's surfactant effect in the intestines, which allow fat and water into the feces to soften the stool.
Sur-q-lax’s mechanism of action was investigated in 1985 on healthy patients. Sur-q-lax was added directly to the jejunum based on calculated concentrations of docusate in the jejunum. At this concentration, there was an increase in secretion of water, sodium, chloride, and potassium as well as a decrease in absorption of glucose and bicarbonate. Based on in vitro data, the authors suggested this effect was due to an increase in intracellular cyclic AMP either directly through docusate or E series prostaglandins.
