  1. 01HumanRandomized controlled trialPharmacokinetics

    In healthy volunteers, tesamorelin did not change simvastatin exposure: AUC and Cmax ratios stayed within the usual no-effect range.

    In plain wordsIn healthy volunteers, tesamorelin did not change how much simvastatin the body took up, compared with simvastatin alone.

    Summary
    For simvastatin, A/B ratios of least squares geometric means and corresponding 90% confidence intervals (CIs) for AUC0-t , AUC0-inf and Cmax were contained within the usual no effect range of 80-125%.
    1 context sentence
    Summary · context
    In two randomized, two-way crossover studies, subjects were administered 2 mg tesamorelin on Days 1-7 with 80 mg simvastatin or 100 mg ritonavir co-administered on Day 6 (Treatment A), and a single dose of simvastatin or ritonavir alone on Day 6 (Treatment B).

  3. 03HumanRandomized controlled trialPharmacokinetics

    In healthy volunteers, the lower 90% CI of the ritonavir Cmax ratio with tesamorelin was 74.8%, a minor decrease in rate of exposure.

    In plain wordsIn healthy volunteers, tesamorelin slightly lowered the peak ritonavir level compared with ritonavir alone; the authors call this a minor decrease.

    Summary
    but the lower CI for Cmax was 74.8%, suggesting a decreased rate of exposure.

    Summary · context
    since the A/B ratios for AUCs and Cmax parameters were approximately 90%, these were minor decreases
