Abstract
The study was performed to compare the bioavailability of two Pramipexole 0.125 mg tablet formulations: the test formulation was pramipezan (pramipexole) manufactured by Cobalt Pharmaceuticals, Canada/ Arrow Farmacutica Ltda * . Sifrol (Pramipexole) from Boehringer Ingelheim do Brasil Qumica e Farmacutica Ltda was used as reference formulation. The study was conducted open with randomized two period crossover design and 8 days wash out period in 48 volunteers of both sexes. Plasma samples were obtained over a 48 hour interval. Pramipexole was analyzed by LC-MS-MS in the presence of Tansulosina as internal standard. The mean ratio of parameters C max and AUC 0-t and 90% confidence intervals of correspondents were calculated to determine the bioequivalence. The means AUC 0-t for test and reference formulation were 8201.90 pg.h/mL and 7891.56 pg.h/mL, for AUC 0- were 8574.71 pg.h/mL and 8288.01 pg.h/mL and, for C max 642.09 pg/mL and 633.94 pg/mL, respectively. Geometric mean of pramipezan (pramipexole) /Sifrol 0.125 mg individual percent ratio was 103.61% AUC 0-t , 103.13% for AUC 0- and 100.81% for C max . The 90% confidence intervals were 98.02 -109.51%, 97.95 -108.59%, 93.06 -109.21%, respectively. Since the 90% confidence intervals for C max , AUC 0-t and AUC 0- were within the 80 -125% interval proposed by Food and Drug Administration, it was concluded that Pramipezan (pramipexole) 0.125 mg tablet was bioequivalent to Sifrol 0.125 mg tablet according to both the rate and extent of absorption.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
