Bioequivalence Studies of Tacrolimus Capsule under Fasting and Fed Conditions in Healthy Male and Female Subjects
Bibliographic record
Abstract
The bioequivalence of tacrolimus (CAS 104987-11-3) 5 mg capsules was assessed in two single-dose, open-label, randomIzed 2-way crossover trials with a minimum washout period of 14 days; one trial was conducted under fasting condition (n = 44) and the other one under fed condition (n = 48). Blood samples were collected over a 120-h period and concentrations were assayed using a liquid chromatography tandem mass spectrometry (LCMS/MS) method. A non-compartmental method was used for calculation of pharmacokinetic parameters. Under fasting conditions, mean AUC(0-t), AUC(0-inf) and C(max) were comparable between the test (296 ng x h/mL, 318 ng x h/mL and 32 ng/ mL, respectively) and the reference formulations (289 ng x h/mL, 309 ng x h/mL and 33 ng/mL, respectively). T(max) was reached between 1.5 and 2 h post-dose. Mean AUC(0-t), AUC(0-inf) and C(max) were also comparable under fed conditions (154 ng x h/mL, 169 ng x h/mL and 7.6 ng/mL, respectively, for the test and 161 ng x h/mL, 176 ng x h/mL and 7.5 ng/mL, respectively, for the reference formulation). Under fed conditions, T(max) was reached between 5 and 6 h post-dose. 90% geometric confidence intervals were all within the acceptable 80-125% limit, suggesting bioequivalence between the generic product and the innovator product.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
