Inclusion criteria

* Able to provide written informed consent prior to any study procedures, and willing and able to comply with study procedures. * Diagnosis of chronic IDIOPATHIC constipation, including experiencing constipation for 12 or more weeks in the preceding 12 months (defined by Rome III criteria for Functional Constipation, but all patients must meet the modified criterion of a history of ≤4 average defecations per week) * Stable concomitant medications (no changes in regimen for at least 2 weeks prior to baseline period) * Body mass index of 18-40 kg/m2 * Females must not be lactating or pregnant

Exclusion criteria

* Unable/unwilling to provide informed consent or to comply with study procedures * Diagnosis of secondary constipation e.g. underlying general neurological disease such as Parkinsonism, multiple sclerosis, diseases associated with peripheral neuropathy, iatrogenic constipation * Structural or metabolic diseases that affect the GI system NOTE: Patients with clinical suspicion of upper or lower GI obstruction must have been evaluated per standard of care and obstruction ruled out before screening * Unable to withdraw the following medications 48 hours prior to baseline period and throughout the study (except as protocol defined rescue medications): * Medications that alter GI transit including laxatives, magnesium and aluminum containing antacids, prokinetics, erythromycin, narcotics, anti-cholinergics, tricyclic antidepressants, SNRI and newer antidepressants * Selective serotonin reuptake inhibitor (SSRI) antidepressants are permissible at low, stable doses * Analgesic drugs including opiates, NSAIDs and COX-2 inhibitors * GABAnergic agents * Benzodiazepines * NOTE: stable doses of thyroid replacement, estrogen replacement, low dose aspirin for cardioprotection, and birth control (but with adequate backup contraception as drug-interactions with birth control have not been conducted) are permissible * Drugs with a low therapeutic index, such as warfarin, digoxin, anti-seizure medications * History of surgery within 60 days of screening * Acute or chronic illness or history of illness, which in the opinion of Investigator, could pose threat/harm to the patient or obscure interpretation of laboratory test results or interpretation of study data such as frequent angina, Class III or IV congestive heart failure, moderate impairment of renal or hepatic function, poorly controlled diabetes, etc * History of hypersensitivity to mannitol (an ingredient of both active and placebo study medications) * Clinically significant abnormalities on screening laboratories or physical examination as determined by Investigator * Abnormal 12-lead electrocardiogram (ECG), including evidence of acute myocardial or subendocardial ischemia and clinically significant arrhythmias or conduction abnormalities (including prolonged QTc \> 500 msec) or abnormal blood pressure at screening except minor deviations deemed to be of no clinical significance by Investigator * Acute GI illness within 48 hours of initiation of the baseline period * ALT or AST \> 1.2 X upper limit of normal during screening * Females who are pregnant or breastfeeding * History of excessive alcohol use or substance abuse * Participation in an investigational clinical study within 30 days prior to dosing in the present study * Any other reason, which in the opinion of the Investigator, would confound proper interpretation of the study
