Conlax Uses, Dosage, Side Effects, Food Interaction and all others data.
Conlax works by stimulating enteric nerves to cause colonic contractions. It is also a contact laxative; it increases fluid and salt secretion. Action of bisacodyl on small intestine is negligible; stimulant laxatives mainly promote evacuation of the colon.
Patients should be counselled regarding abdominal pain, nausea, vomiting, or a change in bowel function that lasts longer than 2 weeks. It has a wide therapeutic index, as patients can take 5-15 mg orally. Patients taking bisacodyl should be counselled before taking the medication if they are already experiencing abdominal pain, nausea, vomiting, or a change in bowel function lasting longer than 2 weeks. Patients should also be counselled to stop taking the medication if they experience rectal bleeding or no bowel movement in 12 hours.

How Conlax works
Conlax 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.
Conlax 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. Conlax decreases expression of aquaporin 3, preventing water from moving into the vasculature, which may contribute to increased water in the colon.
Conlax directly stimulates parasympathetic nerves in the colon, stimulating contraction of longitudinal smooth muscle but not circular smooth muscle.

In lactating women, 10mg of oral bisacodyl reaches a Cmax of 20.5-195 ng/mL, with a Tmax of 3-4 hours, and a geometric mean AUC after a single dose of 471 h*ng/mL. After multiple doses, the geometric mean AUC decreases to 311 h*ng/mL.
Half Life
Data regarding the half life of bisacodyl is not readily available. The half life of the active metabolite, BHPM, in lactating women was 7.3 h after a single 10 mg oral dose and 10.0 h after multiple doses.
Clearance
