After intravenous administration of I—1.3 mg/rrf of bortezomib in patients without renal or hepatic impairment, there is a rapid distribution phase (<10 minutes), followed by a longer elimination phase of 5—15 hours. Plasma protein binding averaged 83%. The mean terminal elimination in preclinical studies was 5.4 hours, with an average clearance of 66 Uh. Peak pharmacodynamic activity (proteasome inhibition) occurred at I hour with a mean of 61% inhibition and a tyi of 24 hours. Inhibition of the 20S subunit was 10—30% at 96 hours. Proteasome inhibition is highly concentration dependent. 

Using ultrafiltration techniques, several investigators have reported protein-bound and nonprotein-bound fractions of plasma aluminium. Lundin et al. (1978) studied the partition of aluminium in the plasma of 10 normal individuals using ultrafiltration with membranes having a cutoff of 6,000-8,000 daltons. The results obtained showed that the protein binding averaged 59% of total serum aluminium. 

To understand the estimation of average drug-receptor binding energies... 

Figure 7-3 shows a comparison of observed binding energies with the calculated average binding energies for a few drugs. 

Until now, we have discussed the use of additivity schemes to estimate global properties of a molecule such as its mean molecular polarizability, its heat of formation, or its average binding energy to a protein receptor. 

Com symp soflds are also dry products, have a smaller average size, and are comparatively sweeter (12). Both maltodextrins and com symp soflds are used to prevent caking enhance dispersibiUty and solubiUty provide body or bulk impart deskable texture bind, carry, and protect flavors control extmsion expansion provide viscosity form films and coatings provide an oxygen barrier inhibit crystallization control sweetness improve sheen improve organoleptic characteristics slow meltdown and improve freeze—thaw stabiUty.
