Pharmacokinetics of Sulfisoxazole in Young and Elderly Subjects
Bibliographic record
Abstract
The pharmacokinetics of sulfisoxazole was studied in 6 elderly (age 63-75 years) and 7 young (age 22-37 years) healthy nonsmoking volunteers following the oral administration of 2 g of Gantrisin. The plasma levels of sulfisoxazole obtained in the postabsorption phase were higher in the elderly subjects. There was no significant variation between the two groups of volunteers in the absorption rate constant, Cmax, bioavailability, the fraction of the dose of sulfisoxazole excreted unchanged, the area under the plasma curve of the N4-acetyl conjugate formed, and in the apparent volume of distribution of the drug. The tmax value and plasma half-life of sulfisoxazole were significantly longer, and the total body and renal clearances of the drug decreased in the elderly subjects. Diminished renal function as estimated by the creatinine clearance and urinary flow may explain the slower elimination of sulfisoxazole in the elderly subjects. Therefore, advancing age should be considered as a factor in the adjustment of sulfisoxazole dosage.

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.
