Pharmacokinetics: The Absorption, Distribution, and Excretion of Drugs OBJECTIVES After studying this chapter, the reader should be able to: • Explain the meaning of the terms absorption, distribu-tion, metabolism, and excretion. • List two physiologic factors that can alter each of the processes of absorption, distribution, and excretion.

Pharmacokinetics is the study of the time course of a drug within the body and incorporates the processes of absorption, distribution, metabolism, and excretion (ADME). The simplest pharmacokinetic concept is that based on concentration of drug in the biological matrix.

Absorption is a primary focus in drug development and medicinal chemistry, since a drug must be absorbed before any medicinal effects can take place. Moreover, the drug's pharmacokinetic profile can be easily and significantly changed by adjusting factors that affect absorption. Absorption is the first step in pharmacokinetics. In this video you'll learn the steps This video on Absorption is the first in the Pharmacokinetics series.

First-pass metabolism decreases with age, which may increase systemic absorption of some medications such as oral nitrates, beta-blockers, estrogens, and calcium channel blockers. Pharmacokinetics Basics- Absorption, Distribution, Metabolism and Excretion. The four processes involved when a drug is taken are absorption, distribution, metabolism and elimination or excretion (ADME). Pharmacokinetics is the way the body acts on the drug once it is administered.

Chart Pharmacokinetics Clinical implications The rate of absorption determines the required time for the administered drug to reach an effective plasma concentration and may thus affect the onset of the drug effect.

Monitoringdrugintheblood (plasma/serum)orsiteofmeasurement The differential equation that follows relates changes in drug concentration in the blood with time to the absorption and the elimination rates: dX dt DK aX a KX (6.4) where dX=dt is the rate (mg h1) of change of amount Pharmacokinetics 2 - Absorption - YouTube.

Absorption . The first stage of pharmacokinetics is absorption which refers to the way that a drug is being absorbed from its pharmaceutical formulation into the bloodstream. One major factor influencing absorption is the route of drug administration.

In this video you'll learn the steps absorption is generally slower SC than IM, due to poorer vascularity. Absorption can be facilitated by heat, massage or vasodilators. It can be slowed by coadministration of vasoconstrictors, a practice commonly used to prolong the local action of local anesthetics. As above, arm > thigh. 6. Inhalation In pharmacology (and more specifically pharmacokinetics), absorption is the movement of a drug into the bloodstream. Absorption involves several phases.

Dosage forms (eg, tablets, capsules, solutions), consisting of the drug plus other ingredients, are formulated to be given by various routes (eg, oral, buccal, sublingual, rectal, parenteral, topical, inhalational).
