WebThis term is defined as the ratio of drug concentration in the ultrafiltrate to the pre-filter plasma water concentration of the drug. If the sieving coefficient is close to 1.0, the drug has relatively free passage across the filter. The following table presents sieving coefficient data from in vitro and in vivo evaluations. WebMay 11, 2016 · The value obtained for the case of C p = 0 mg/mL is very close to unity and therefore represents an intrinsic sieving coefficient for an unretained small molecule. The apparent sieving coefficients obtained with protein present are much lower and serve to illustrate the impact of protein-binding on the rate of dye clearance. how to score the audit-c https://profiretx.com
