on linear and semi-log scales for doses of 2 mg and 5 mg from study 25542 show that sublingual asenapine exhibits linear 2-compartment pharmacokinetics over this dose range, (see Figure 35 to Figure 38). When administered sublingually, linearity over the range of 0.02 mg to 5 mg is confirmed by the mean Apply nonlinear pharmacokinetics to describe steady-state plasma concentrations following parenteral and/or oral phenytoin therapy. Introduction Pharmacokinetics provides a mathematical basis to assess the time course of drugs and their effects in the body. It enables the following processes to be quantiﬁed: Absorption Distribution Metabolism Equations/Useful_pharmacokinetic_equ_5127 2 Constant rate infusion Plasma concentration (during infusion) C k CL 0 1 e kte Plasma concentration (steady state) C k CL 0 Calculated clearance (Chiou equation) CL k CC Vd C C CC t t 2 2 0 12 12 12 21 Short-term infusion Peak (single dose) C Introduction to Pharmacokinetics and Pharmacodynamics Pharmacokinetics is currently deﬁned as the study of the time course of drug absorption, distribution, metabo-lism, and excretion. Clinical pharmacokinetics is the application of pharmacokinetic principles to the safe and effective therapeutic management of drugs in an individual patient.

Nonlinear pharmacokinetics is the characteristic of drugs that briefs that the absorption and bioavailability can cause increases in drug concentrations that are disproportionately high or low relative to the change in dose.

Adverse events, observed included granulocytopenia, dizziness and tolerability Tadalafil has linear pharmacokinetics over the dose range of 2.5–20 mg.12 A steady state of tadalafil is reached after 5 days of daily administration, Linear pharmacokinetics is so-called because the graph of the relationship between the various factors involved (dose, blood plasma concentrations, elimination, etc.) gives a straight line or an approximation to one.

For a drug with linear PK, we would expect that a 2-fold increase in dose would result in a 2-fold increase in drug exposure. When the dose of EPO is doubled from 1 μg/kg to 2 μg/kg, the exposure increases more than 2-fold. ◼Nonlinear pharmacokinetic drugs pose a challenge in therapy management due to their complex nature.
