Relationship of serum ACE inhibition to oral dose of enalapril in normotensive volunteers
Bibliographic record
Abstract
OBJECTIVES: To determine the relationship between oral dose of enalapril and parameters describing serum angiotensin converting enzyme (ACE) inhibition. METHODS: Four different oral doses of enalapril maleate (2.5, 5, 10 and 20 mg) were administered to six healthy normotensive volunteers, in a four-period crossover study. Serum ACE inhibition profiles were determined in each case using a synthetic substrate, hippuryl-histidyl-leucine (HHL). Pharmacodynamic parameters of the drug (Emax and AUEC0-->24) were calculated and their relationship to oral doses investigated using linear regression analysis. RESULTS: There was no significant relationship between drug dose and the two pharmacodynamic parameters (Emax and AUEC0-->24). The r2 values were 0.548 (F=3.63, P=0.153) and 0.6360 (F=5.24, P=0.106) for Emax and AUEC0-->24, respectively. CONCLUSION: The extent of serum ACE inhibition, as the main determinant of the blood pressure lowering effect of enalapril, is not dose-dependent within the single dose range of 2.5-20 mg.

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.
