NCT00834808

Brief Summary

The purposes of this study were:

  • To evaluate the plasma pharmacokinetic profile of tramadol and its principal metabolite, the O-desmethyltramadol, after a single oral administration of 100, 200 and 300 mg of tramadol as the Labopharm extended-release formulation prepared with Contramid.
  • To assess the dose linearity of tramadol and its principal metabolite, the O-desmethyltramadol, between 100 mg and 300 mg following a single dose administration of the Labopharm extended-release formulation prepared with Contramid under fasting conditions in young healthy volunteers.

Eligibility Criteria

Age18 Years - 45 Years
Sexmale
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Availability of subject for the entire study period and willingness to adhere to protocol requirements as evidenced by the informed consent form duly signed by the subject.
  • Males aged from 18 to 45 years inclusively and with Body Mass Index (BMI) between 18 and 30 kg/m2 inclusively.
  • Clinical laboratory values within 10% above or below the laboratory's stated normal range; if not within this range, the clinical investigator will decide if they were not clinically significant and recorded this fact on the Case Report Form (CRF).
  • Healthy according to the physical examination and laboratory results.
  • Normal cardiovascular function according to a 12-lead electrocardiogram (ECG).
  • Non-smoker or subjects smoking no more than 5 cigarettes per day (or equivalent) and able to abstain from smoking during inpatient phases of the study.
  • Subjects covered by Social Security in compliance with the recommendations of French Law relating to biomedical research.
  • Subjects with normal dietary requirements (neither vegetarian, nor on a diet).

You may not qualify if:

  • History of hypersensitivity to tramadol or any other compounds.
  • Presence or significant history of gastrointestinal, liver or kidney disease, or any other conditions known to interfere with the absorption, distribution, metabolism or excretion of drugs.
  • Presence or significant history of cardiovascular, pulmonary, haematological, neoplasic, neurological, psychiatric, endocrine, immunological or dermatological disease.
  • Presence or significant history of glaucoma.
  • Supine pulse rate lower than 45 beats per minute (bpm) after 5 minutes at rest or higher than 100 bpm.
  • History of hypotensive episodes or a standing systolic blood pressure reading of \<100 mmHg or a diastolic reading of \<45 mmHg, measured on the screening day.
  • History of hypertensive episodes or a supine systolic blood pressure reading of \>145 mmHg or a diastolic reading of \>95 mmHg, measured on the screening day.
  • Presence of atrioventricular (AV) block assessed during pre-study evaluation or during the study. The lower limit considered for a first degree AV block was be a PR interval of 200 millisecond (msec).
  • Maintenance therapy with any drug, or history of drug dependency, alcohol abuse (\>3 units of alcohol per day), or serious psychological disease.
  • Subjects consuming large quantities of drinks containing xanthine bases (coffee, tea, chocolate or cola; more than 6 cups or glasses per day).
  • Any clinically significant illness in the previous 21 days before day 1 of this study.
  • Subjects who had undergone general anesthesia within 3 months prior to the present study.
  • Use of drugs known to affect liver enzymes (eg, inducers or inhibitors of Cytochrome P450) in the previous 30 days before day 1 of this study (eg, all barbiturates, corticosteroids, di \& methyl-phenylhydantoin).
  • Use of any medication (including OTC preparations) in the previous 14 days before day 1 of this study.
  • Donation of 350 mL (or more) of blood in the previous 3 months or participation in another clinical trial in the previous 3 months before day 1 of this study.
  • +8 more criteria
