Stability of Allopurinol in Extemporaneously Compounded Oral Suspensions with Oral Mix and Oral Mix SF.
Bibliographic record
Abstract
Allopurinol is a xanthine oxidase inhibitor used to reduce the production of uric acid in the body. Commercial tablets may be crushed and suspended in a compounding vehicle and provide an alternative dosage form for patients with difficulty swallowing, such as children. The stability of a compounded preparation of allopurinol 20 mg/mL was evaluated in ready-to-use vehicles, namely Oral Mix and Oral Mix SF. A stability indicating HPLC method was developed and validated to assess the amount of allopurinol over time. Formulations were stored in tightly closed, light resistant plastic containers at both room temperature and refrigerated conditions. Chemical analysis, pH measurement and organoleptic assessment were performed at predetermined time points up to 90 days. Antimicrobial effectiveness testing was also performed after 90 days of storage at room temperature. The stability study demonstrated that the allopurinol 20 mg/mL suspensions prepared from commercial tablets in Oral Mix and Oral Mix SF was stable up to 90 days under the tested conditions.

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.
