Package ICSpkTS September 4, 2012 Type Package Title Simulation of pharmacokinetic trials after administration of inhaled corticosteroids. Version 1.0 Date 2012-09-04 Author Benjamin Weber Maintainer Benjamin Weber <benjaminweber@ufl.edu> Description Simulation of pharmacokinetic (PK) trials after administration of inhaled corticosteroids (ICS). PK trials can be simulated in a parallel design after administration of two different hypothetical ICS, two different formulation of the same ICS, or the same formulation of an ICS in a different patient population. 90 % confidence intervals of the geometric means ratios for the area under the concentration time curve (AUC) and the maximum plasma concentration (Cmax) will be calculated. Individual and average plasma concentration time profile plots as well as tables containing the individual and average plasma concentration time data and the individual PK parameters (e.g., clearance, volume of distribution, absorption rate constant, lung deposition) and PK metrics (AUC, Cmax) can be optionally obtained.
