Brief Summary

The objective of this study is to compare the rate and extent of absorption of two Tramadol Contramid® OAD 300 mg controlled-release tablets from two different manufacturing sites, administered as 1 x 300 mg controlled-release tablet under fasting conditions. The effect of food on the to-be-marketed formulation was also assessed.

Outcome Measures

Primary Outcomes (3)

• AUC(0-t)

  Area under the plasma concentration (AUC) versus time curve to the last measurable concentration.

  48 hours

• AUC(0-∞)

  The area under the plasma concentration (AUC) curve was estimated by extrapolating to infinity AUC0-t. The extrapolation to infinity was done by regression with the last log-transformed data to estimate the terminal area by means of the line that maximized R'2 (coefficient of determination). The units are ng.h/mL. h=hours

• Cmax

  Maximum plasma concentration (Cmax)

Secondary Outcomes (2)

• Tmax

• t1/2

• Use of any drugs known to induce or inhibit hepatic drug metabolism (examples of inducers: barbiturates, carbamazepine, phenytoin, glucocorticoids, omeprazole; examples of inhibitors: antidepressants (Selective serotonin reuptake inhibitors \[SSRIs\]), cimetidine, diltiazem, macrolides, imidazoles, neuroleptics, verapamil, fluoroquinolones, antihistamines) within 30 days prior to administration of the study medication.
• Use of an investigational drug or participation in an investigational study within 30 days prior to dosing.
• Clinically significant history or presence of any gastrointestinal pathology (e.g. chronic diarrhea, inflammatory bowel diseases), unresolved gastrointestinal symptoms (e.g. diarrhea, vomiting), liver or kidney disease, or other conditions known to interfere with the absorption, distribution, metabolism, or excretion of the drug.
• Any clinically significant history or presence of neurological, endocrinal, cardiovascular, pulmonary, hematologic, immunologic, psychiatric, or metabolic disease.
• Use of prescription medication within 14 days prior to administration of study medication or over-the-counter products (including natural food supplements, vitamins, garlic as a supplement) within 7 days prior to administration of study medication, except for topical products without systemic absorption and hormonal contraceptives.
