Background and aimsColonoscopy has a vital role in the diagnosis of inflammatory bowel disease (IBD), as well as in the estimation of disease severity, monitoring response to therapy, and surveillance for neoplasia. We performed a systematic review of randomised trials of various bowel preparations for colonoscopy in IBD.MethodsWe searched various electronic databases (PubMed, Embase, and CENTRAL) for studies reporting about the use of various strategies to improve colonoscopy preparation in IBD. We included only randomized clinical trials (RCTs). A network meta-analysis was done using a frequentist approach to compare the effectiveness of various bowel preparations. The risk of bias was assessed using Cochrane risk of bias tool 2.0. Other outcome parameters like compliance, tolerance, acceptance, and adverse effects were assessed qualitatively.ResultsSeven RCTs reporting about 960 patients were included. On comparison with 4 liter (L) of poliethylen glycol (PEG), oral sulfate solution (OR=1.1, 95%CI: 0.65-1.86); PEG2L/Ascorbate (OR=0.98, 95%CI: 0.65-1.48); PEG1L (OR=1, 95%CI: 0.55-1.81); PEG2L plus bisacodyl (OR=1.08, 95%CI: 0.71-1.65); PEG4L plus simethicone (OR=1, 95%CI: 0.67-1.50); PEG/ sodium picosulfate and magnesium citrate (SPMC) 1.5L (OR=0.99, 95%CI: 0.55-1.78); SPMC 2L (OR=1.09, 95%CI: 0.61-1.97) had similar effectiveness. Three RCTs reported compliance, five RCTs reported tolerance, two studies reported patient acceptance and five RCTs reported data on the willingness of patients to repeat the procedure in the future. Low-volume preparations had better compliance, tolerance, acceptance, and willingness to repeat. No difference in additional outcomes like change in disease activity after colonoscopy, procedure-related outcomes after colonoscopy like cecal intubation rate, and change in electrolyte levels were found.ConclusionVarious bowel preparations had similar effectiveness in respect to colonoscopy preparation in IBD patients. Low-volume preparations have better compliance, tolerance, and acceptance. The systematic review was limited by a small number of included RCTs.

Bisacodyl was patented on 25 September 1956[L33045] but has been used as a laxative since 1952.[A233300]

Patients should be treated with symptomatic and supportive measures.
The oral LD50 in rats is 4320 mg/kg, and in mice is 17500 mg/kg.
[L33070]
Bisacodyl stimulates adenylate cyclase, increasing cyclic AMP, leading to active transport of chloride and bicarbonate out of cells.[A233300] Sodium ions, potassium ions, and water passively leave the cell; while sodium and chloride ions are unable to be reabsorbed.[A233300]
Water is also be transported from the luminal side of cells into the vasculature by aquaporin 3.[A233395] Bisacodyl decreases expression of aquaporin 3, preventing water from moving into the vasculature, which may contribute to increased water in the colon.[A233395]
Bisacodyl directly stimulates parasympathetic nerves in the colon, stimulating contraction of longitudinal smooth muscle but not circular smooth muscle.[A233280][A233300]
How the body processes this drug — absorption, distribution, metabolism, and elimination
[A233275][A233280]
A 10 mg enteric coated oral tablet reaches a Cmax of 26 ng/mL with a Tmax of 8 hours, while a 10 mg oral solution reaches a Cmax of 237 ng/mL with a Tmax of 1.7 hours.
[L33070]
A 10 mg suppository reaches a Cmax of 0-64 ng/mL.
[L33070]
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.
[A207700]
After multiple doses, the geometric mean AUC decreases to 311 h\*ng/mL.
