Abstract
OBJECTIVE: To describe the pharmacokinetics of cyclosporine (CyA) in healthy dogs after oral administration alone or in combination with orally administered cimetidine. ANIMALS: 10 healthy adult Beagles. PROCEDURE: Dogs were randomly assigned to receive CyA alone or CyA in combination with cimetidine. After a washout period of 2 weeks, dogs then received the alternate treatment. The CyA plus cimetidine treatment required administration of cimetidine (15 mg/kg of body weight, PO, q 8 h) for 8 days and administration of CyA (5 mg/kg, PO, q 24 h) on days 6 through 8. The CyA treatment alone required administration of CyA (5 mg/kg, PO, q 24 h) for 3 days. On the third day of CyA administration during each treatment, blood samples were collected immediately before (time 0) and 0.5, 1, 1.5, 2, 2.5, 3, 5, 7, 9, 11, 13, 15, 21, and 24 hours after initiating CyA administration. RESULTS: Time until maximum CyA concentration was significantly longer for CyA in combination with cimetidine. Assessment of estimated pharmacokinetic variables revealed a significantly faster rate of change in the distribution phase for CyA in combination with cimetidine. Maximum CyA concentration differed significantly among dogs but did not differ significantly between treatments. CONCLUSIONS AND CLINICAL RELEVANCE: Analysis of our data suggests that cimetidine may affect absorption of orally administered CyA, but overall, it does not affect the pharmacokinetics of CyA. There is considerable variability in the maximum concentration of CyA among dogs, and monitoring of blood concentrations of CyA during treatment is advised.

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
