NCT03803371

Brief Summary

The sponsor, Pfizer has developed a formulation of tramadol hydrochloride/ paracetamol 37.5 mg/ 325 mg (test drug) as a generic alternative to the reference listed product Ultracet®. In order to meet the requirements for registration as a generic drug, this study is being conducted to demonstrate the bioequivalence between the formulation of tramadol hydrochloride/ paracetamol 37.5 mg/ 325 mg provided by Pfizer and the reference drug tramadol hydrochloride/ paracetamol 37.5 mg/ 325 mg, available in the pharmaceutical market in Brazil (Ultracet®, Janssen Cilag Farmacêutica Ltda).

  • Clinically significant infections within the past 3 months (eg, those requiring hospitalization or parenteral antibiotics, or as judged by the Investigator), evidence of any infection within the past 7 days, history of disseminated herpes simplex infection or recurrent or disseminated herpes zoster.
  • Any condition possibly affecting drug absorption (eg, gastrectomy, colon resection, etc.).
  • Research subjects with a history of, or current evidence for, severe gastrointestinal narrowing (pathologic or iatrogenic).
  • History of or current positive results for any of the following serological tests: hepatitis B surface antigen (HBsAg), hepatitis B core antibody (HBcAb), anti hepatitis C core antibody (HCV Ab), or human immunodeficiency virus (HIV) 1 and 2.
  • Malignancy or a history of malignancy
  • A positive urine drug test.
  • A positive alcohol screen.
  • History of regular alcohol consumption exceeding 14 drinks/week for female subjects or 21 drinks/week for male subjects \[1 drink = 5 ounces (150 mL) of wine or 12 ounces (360 mL) of beer or 1.5 ounces (45 mL) of hard liquor\] within 6 months before screening.
  • Use of tobacco or nicotine containing products in excess of the equivalent of 5 cigarettes per day.
  • Treatment with an investigational drug within 6 months or 4 or 5 half lives preceding the first dose of investigational product (whichever is longer).
  • Pregnant female subjects, breastfeeding female subjects, fertile male subjects and female subjects of childbearing potential who are unwilling or unable to use a highly effective method of contraception as outlined in this protocol from at least 14 days prior to the first dose of investigational product until at least 28 days after the last dose of investigational product.
  • Use of prescription or nonprescription drugs and dietary supplements within 14 days or 5 half lives (whichever is longer) prior to the first dose of investigational product. Limited use of non prescription medications that are not believed to affect research subject safety or the overall results of the study may be permitted on a case by case basis following approval by the sponsor.
  • Herbal supplements, hormonal methods of contraception (including oral and transdermal contraceptives, injectable progesterone, progestin subdermal implants, progesterone releasing intrauterine devices \[IUDs\], vaginal ring, and postcoital contraceptive methods), and hormone replacement therapy must have been discontinued at least 28 days prior to the first dose of investigational product.
