Irritable Bowel Syndrome Characterized by Constipation
Conditions
Brief summary
The main purpose of this study is to investigate the feasibility of a follow-up larger RCT on the efficacy of Botanical Tincture to relieve abdominal pain in people with Irritable Bowel Syndrome Constipation Predominant (IBS-C).
Detailed description
The randomized pilot trial will address subject recruitment, retention, and subject compliance with protocol. A secondary is to learn if people with IBS-C are able to tolerate Botanical Tincture and the effect of taking Botanical Tincture on abdominal pain, bloating, and bowel movements.
Interventions
DRUGBotanical Tincture
Study participants will meet with the Investigator at baseline and week 2, 6, and 10 after the study period begins. Trial continuation criteria at 2 weeks after the start of the study includes abdominal pain intensity and stool frequency. Participants randomized to Botanical Tincture will have a 2-week withdrawal period. On the visits study participants may expect to be asked about epidemiologic information, IBS medications, IBS Quality of Life survey instruments, and daily diary of pain scale, bloating scale, and number of bowel movements.
OTHERPlacebo
Study participants will meet with the Investigator at baseline and week 2, 6, and 10 after the study period begins. Trial continuation criteria at 2 weeks after the start of the study includes abdominal pain intensity and stool frequency. On the visits study participants may expect to be asked about epidemiologic information, IBS medications, IBS Quality of Life survey instruments, and daily diary of pain scale, bloating scale, and number of bowel movements.

Inclusion criteria
* Patients meeting ROME IV criteria for the diagnosis of irritable bowel syndrome that requires that patients have had recurrent abdominal pain on average at least 1 day per week during the previous 3 months that is associated with 2 or more of the following : * Related to defecation (may be increased or unchanged by defecation) * Associated with a change in stool frequency * Associated with a change in stool form or appearance * Abdominal Pain Intensity: average of worst daily (in past 24 hours) abdominal pain score of \>= 3 on a 0 to 10 point scale over last week * Stool Frequency: \< or = to 3 Complete Spontaneous Bowel Movement(CSBM) in the previous week * Reported bloating rating \> or = 2 on 5-point scale \[0 (absent) - 4 (very severe)\] in previous week * English speakers, as all surveys are in English
Exclusion criteria
* Patients with known hypersensitivity to any component of the trial drugs * History of eating disorders * Patients with a history of diseases with abdominal symptoms that can resemble IBS * Presence of any other known acute or chronic gastrointestinal disorder * History of abdominal surgery (cholecystectomy and appendectomy can be tolerated when performed at least one year previously) * Pregnancy or breast feeding * Current or past history of alcohol dependence * Based on lack of adequate scientific evidence to predict drug-drug interaction in vivo, current use of strong inhibitors or inducers for CYP enzymes and participants are instructed not to take any medications that are strong inhibitors or inducers for CYP enzymes during the course of the study * Vulnerable Subjects. The study will not include vulnerable subjects (such as, those with limited autonomy or those in subordinate hierarchical positions). Children, pregnant women, nursing home residents or other institutionalized persons, students, employees, fetuses, prisoners, and persons with decisional incapacity will not be included.
