  • Results of screening and clinical laboratory tests are within normal range or considered not clinically significant by the Principal Investigator and the Sponsor;
  • Female subjects of childbearing potential must be using a medically acceptable form of birth control for at least 1 month prior to screening (3 months on oral contraceptives), e.g., oral or patch contraceptives, intrauterine device, NuvaRing®, Depo-Provera®, or double-barrier and have a negative pregnancy test at Screening and Day 0 of each dosing period. Female subjects of nonchildbearing potential must be amenorrheic for at least 2 years or had a hysterectomy and/or bilateral oophorectomy

Exclusion Criteria:

  • History of hypersensitivity to aspirin (ASA), naproxen sodium, or acetaminophen, and similar pharmacological agents or components of the products;
  • Females who are pregnant or lactating;
  • Loss of blood in excess of 500 ml within 56 days of the first dose of trial treatment (e.g., donation, plasmapheresis or injury);
  • History of gastrointestinal bleeding or perforation, related to previous NSAID therapy. Active, or history of recurrent peptic ulcer/hemorrhage (two or more distinct episodes of proven ulceration or bleeding);
  • Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic diseases or malignancies;
  • Positive alcohol or drug test;
  • Have taken any medications (except acceptable forms of birth control) within 10 days prior to dosing or throughout the study, unless in the opinion of the Investigator and the Sponsor, the medication will not interfere with the study procedures, data integrity, or compromise the safety of the subject;
  • Have taken ASA, ASA-containing products, acetaminophen (acetyl-para-amino-phenol or APAP) or any other NSAID (OTC or prescription) 7 days prior to dosing or during the treatment period, other than study treatment;
  • Smokers or currently consuming any type of tobacco product(s) including any smoking cessation nicotine-containing product (e.g., nicotine patch, nicotine gum);
  • Have taken any vitamin or herbal supplement within 7 days prior to dosing or refuse to refrain from use during the study;
