eff = effective half-life; bio = biologic half-life; A1 = partition coefficient for fast component of serum clearance; α = half-time for fast component of serum clearance; A2 = partition coefficient for slow component of serum clearance; β = half-time for slow component of serum clearance.
Whole-body clearance was monoexponential. Serum clearance was biexponential and conformed to the following equation: A1exp(−a1t) + A2exp(−a2t). A1 and A2 are partition coefficients, and respective t1/2 values correspond to ln(2)/a. All half-lives are in hours.
