Pharmacokinetics

Pharmacokinetics is the branch of pharmacology that describes how the body affects a specific substance after administration.

ADME

ADME stands for Absorption, Distribution, Metabolism, and Excretion in pharmacokinetics.

Pharmacokinetics and Pharmacodynamics

Pharmacokinetics describes the movement of a drug in the body, while pharmacodynamics describes the effect of the drug on the body.

Single-Compartment Model

In the single-compartment model, the most common model of elimination is first-order elimination.

Two-Compartment Model

In the two-compartment model, elimination commonly occurs in the central compartment.

Non-Linearity

Non-linearity can be affected by factors such as saturation of metabolic pathways or protein binding.

Bioavailability

Bioavailability is the proportion of the drug that reaches its site of action.
Bioavailability is 100% for a drug administered intravenously.

Formula to Calculate Drug Concentration

The formula to calculate the amount of a drug in the blood plasma that has the potential to bring about its effect is: Conc. = Dose / (Vd * ka).

Steady State

At steady state, the rate of drug administration is equal to the rate of drug elimination.

Compartmental Analysis

The advantage of compartmental analysis over noncompartmental analysis is that it provides a more detailed understanding of the pharmacokinetic processes.

Ecotoxicology

The main focus of ecotoxicology is the study of the effects of toxic substances on ecosystems.
