A Study of the Potential Interaction Between Bazedoxifene and Atorvastatin in Healthy Postmenopausal Women
Bibliographic record
Abstract
Abstract An open‐label, 3‐period study was conducted in 30 healthy postmenopausal women (mean age, 58.4 years) who received a single oral dose of atorvastatin 20 mg on day 1 (period 1), multiple daily dosing of bazedoxifene 40 mg on days 4‐11 (period 2), and coadministration of atorvastatin 20 mg + bazedoxifene 40 mg on day 12 (period 3). Serial blood samples were collected (24 hours after bazedoxifene and 72 hours after atorvastatin) and assayed for bazedoxifene, atorvastatin, and its ortho‐hydroxy and para‐hydroxy metabolites. Pharmacokinetic parameters were calculated using noncompartmental methods. Bazedoxifene exposure was not altered with coadministration of atorvastatin 20 mg (Cmax and AUCss were within bioequivalence limits). Similarly, atorvastatin and ortho‐hydroxyatorvastatin exposure was equivalent with or without coadministration with bazedoxifene. Para‐hydroxyatorvastatin concentrations were below the limit of quantitation under both conditions. Cmax for atorvastatin and ortho‐hydroxyatorvastatin was 14% and 18% lower, respectively, and Tmax was 20% and 34% longer, respectively, with the combination compared with atorvastatin alone. There were no serious adverse events, and no subjects discontinued the study because of safety. No clinically significant pharmacokinetic interaction was observed between bazedoxifene and atorvastatin or its active metabolites, indicating they may be safely coadministered without dosage adjustment.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
