However because of the long half-life of aminoglycosides in neonates this once daily regimen is more like steady state dosing achieved by 8 hourly dosing in adults.
The potential association between CYP3A5*3, CYP3A4*22, PPARA, POR*28 genotypes and steady state dose-adjusted Tac C0 (C0/D, μg*L-1/mg) or CsA C2 (C2/D, μg*L-1/mg) concentration, 2 7 weeks post-transplantation was investigated.
The same results were shown for both loading and steady-state doses when serum and subcutaneous drug levels were measured [ 5].
Most studies look at the steady-state dose-response of the average phosphorylated substrate versus the kinase-phosphatase balance (K t / P t ).
In this paper, we have studied the steady-state dose-response in basic PDC motif and a modified PDC motif using analytical and numerical methods.
Accurate measurement and steady-state dosing of low aqueous concentrations of hydrophobic PCBs at ng L 1 levels has been challenging in the past.
However, Schalekamp et al. observed a 3.7-mg lower weekly phenprocoumon steady-state dose for CYP2C9*2 carriers and a 4.4-mg lower weekly dose for CYP2C9*3 carriers compared with wild-type carriers [ 36].
In summary, steady-state dosing of clopidogrel 75 mg qd (following a 300 mg loading dose) and dabigatran etexilate 150 mg bid demonstrated no effect on dabigatran PK or PD, or its PK/PD relationships (aPTT, ECT, or TT).
However, these solutions did not appreciably change the steady-state dose responses (data not shown), indicating that under these conditions and model parameters, reaction rate fluctuations do not constitute a significant source of signaling variability.
The objectives of this modeling study were to estimate the differences in the average steady-state dose-normalized BPA plasma and urinary concentrations between adults and children < 2 years of age after BPA administration and to determine the expected average steady-state plasma concentrations of BPA and BPA-Glu in young children after typical feeding scenarios.
Steady-state dose-corrected trough plasma sunitinib concentrations were derived using data from patients who had taken sunitinib for ≥ 10 consecutive days by correcting observed concentrations in patients who underwent dosing modifications based on the 37.5-mg starting dose (starting dose ÷ actual dose).
