Criteria

Inclusion:

Subjects diagnosed with nocturia, as defined by International Continence Society (i.e., the interruption of sleep one or more times at night to void), confirmed by evaluation in participating investigator's urology practice for the following characteristics: nocturia is related to overactive bladder (OAB); nightly ≥2.5 times nocturia present for at least 3 months and not considered caused by persistent or recurrent urinary tract infection; Post-Void Residual (PVR) urine volume must be <80 cc at the time of screening; did not respond well to, or unwilling to have, lifestyle modification, behavioral and conservative therapies, such as dietary changes, timed voiding, urge suppression (e.g., pelvic floor exercises [PFE] at the time of urge episodes), biofeedback, etc.
Males or females, ≥18 years of age with Body Mass Index (BMI) <40.
Women of child-bearing potential (i.e., women who are pre-menopausal or not surgically sterile) must use accepted contraceptive methods (abstinence, intrauterine device [IUD], oral contraceptive or double barrier device) during the study, and must have a negative serum or urine pregnancy test within 1 week prior to treatment initiation.
Ability to understand and sign the study Informed Consent Form (ICF), communicate with the investigators, and understand and comply with the requirements of the protocol, including completion of participation in all phases of the study.
No current or medical history of gastrointestinal bleeding or malformation; bleeding diathesis; or restless leg syndrome.
Not using within 4 weeks before study initiation, or anticipating the use during the study, of the following drugs: antiplatelet or anticoagulant drugs; any Selective Serotonin Re-uptake Inhibitors (SSRIs) or anti-diuretic medications; or warfarin
Resting heart rate between 55 and 100 beats per minute, inclusive of both.

Exclusion:

Pregnant or nursing women.
Known presence of urinary tract infection (UTI) within 4 weeks before study initiation
Known sleep interruptions due to sleep apnea, dyspepsia or other gastro-intestinal symptoms, seizure disorders or other neurologic symptoms
Allergy to or intolerance of acetaminophen, ibuprofen, or any inactive component of the study drug formulations.
A history of allergy to aspirin or other NSAIDs.
Congenital or acquired structural abnormality of the genitourinary tract.
Prostate cancer of any stage that has required any treatment.
Any neurodegenerative disease (including but not limited to Parkinson's Disease, Alzheimer's Disease, Amyotrophic Lateral Sclerosis, Pick's Disease, Multi-Infarct Dementia or recent history of head trauma associated with concussion, stroke or serious cerebrovascular events) which may indicate problems in providing consistent and reliable Patient-Reported Outcomes (PRO) such as diary, Quality-of-Life, etc. required in this study.
Uncontrolled hypertension (blood pressure >150/100 mm Hg).
Serious medical illness, such as significant cardiac disease (e.g. symptomatic congestive heart failure, unstable angina pectoris, myocardial infarction within the past 6 months, uncontrolled cardiac arrhythmia, or New York Heart Association Class II, III or IV), severe debilitating pulmonary disease, or history of stroke (hemorrhagic or thrombotic), A-V malformation, or other cerebrovascular disease.
Receipt of any investigational drug or participation in any clinical trial within 30 days prior to study participation.
Use of acetaminophen, ibuprofen, acetylsalicylic acid (ASA) or any NSAID on the day of entry into the study or any anticipated use during the study. In the event of the need for any unanticipated use of such drugs during the trial, the timing and doses of such use should be carefully recorded and reported at the next visit to the clinic.
Any medical problem requiring uninterrupted use of acetaminophen, ibuprofen, or any NSAIDs, or any other pain medication.
Daily use of phosphodiesterase (PDE) inhibitors (such as sildenafil, tadalafil, vardenafil, avanafil, and udenafil) within 30 days prior to study or any anticipated daily use during the study. (Note: PDE inhibitors are known to have positive effect on voiding dysfunction and thus can interfere with the assessment of Paxerol [Ückert et al 2010].)
History of polyuria or evidence of polyuria (estimation of daily production >2.5 liters of urine).
Uncontrolled Type 1 or 2 diabetes mellitus (HbA1c >7.0%).

Any visual, motor or other sensory abnormality that might predispose to a fall on nocturnal arising to urinate.
Evidence of hyponatremia at baseline.
Any significant disease or abnormality of the neurological, visual, gastrointestinal, hepatobiliary, pulmonary, cardiovascular, genitourinary or musculoskeletal system other than those specified above that, in the opinion of the involved investigator, might compromise the ability of the prospective subject to participate in the study or that could confound interpretation of study results.
Any abnormality on screening medical history, physical examination or clinical laboratory examination other than those specified above that, in the opinion of the involved investigator, might confound interpretation of study results.
Subjects with known hepatitis, HIV-AIDS, or tuberculosis.
Subjects with known dysrhythmia of any form.
