简要总结
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.

- •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).
排除标准

- •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.
