Criteria

Inclusion Criteria:

• Inclusion criteria for screening phase:

• Women aged 18 to 65 years, inclusive

3. straining at defecation in more than 25% of BMs; 4. sensation of a no-rectal obstruction or blockade in more than 25% of BMs; 5. A need for digital manipulation to facilitate evacuation in more than 25% of BMs

• Subjects who has been using PEG or lactulose treatment for more than 1 week at screening

• Be a non-pregnant, non-lactating woman. Sexually active women must be post menopausal, surgically sterile, or practicing an effective method of birth control (eg, prescription oral contraceptives, contraceptive injections, intrauterine device, double barrier method, contraceptive patch, male partner sterilization) before entry and throughout the study. Women must have a negative serum beta-human chorionic gonadotropin pregnancy test at screening and a negative urine pregnancy test immediately prior to study drug titration

• Inclusion Criteria for treatment phase: At Visit 2 (Week 0), the diary of Week -1 will be collected and examined for the presence of chronic constipation. The subject will be considered eligible for treatment phase if the following criteria are met: Number of SCBMs is 2 or fewer during the run-in phase (1 week)

• Subject had NO SBMs during the run-in phase is considered to be constipated

Exclusion Criteria:

• Potential subjects who meet any of the following criteria will be excluded from participating in the study

• Subjects in whom constipation is thought to be drug-induced

• Subjects suffering from secondary causes of CC

• Subjects with severe and clinically uncontrolled cardiovascular, liver, or lung disease, neurologic or psychiatric disorders (including active alcohol or drug abuse), cancer or acquired immune deficiency syndrome (AIDS), or other gastrointestinal or endocrine disorders

• Subjects with clinically significant abnormalities of hematology, urinalysis, or blood chemistry

• Known allergies, hypersensitivity, or intolerance to prucalopride or its excipients

• Women who are pregnant or breast-feeding
