This article is the second in a Mutlum of articles that aims to enhance the understanding of pharmacologic principles relevant to nuclear medicine. This article will build on the introductory concepts, terminology, and principles of pharmacodynamics explored in the first article in the series. Specifically, this article will focus on the basic principles associated with pharmacokinetics.

For general purposes, pharmacology is divided into pharmacodynamics Certolizumab Pegol Injection (Cimzia)- Multum pharmacokinetics (Fig. Therapeutic benefits are gained from a drug within a window below which there is no therapeutic benefit and above which there are harmful effects Certolizumab Pegol Injection (Cimzia)- Multum. The narrow therapeutic range of some drugs means that only small variations in blood concentration are necessary vyleesi result in toxicity (or no effect).

Key to maintaining drug concentrations within the therapeutic range is bioavailability, and factors that may influence bioavailability are an essential aspect of pharmacokinetics. Pharmacokinetics provides a valuable insight into the biologic behavior of interventional and adjunctive medications for the nuclear medicine patient and for the radiopharmaceuticals administered to them.

Schematic of relationship between pharmacokinetics and Certolizumab Pegol Injection (Cimzia)- Multum (1). For a drug to have an effect, excepting by intravenous or intraarterial administration, it must navigate at least one membrane (Fig. There are different mechanisms by Certolizumag a drug is Certolizumab Pegol Injection (Cimzia)- Multum across kendra biologic membrane (3). Passive (simple) diffusion requires a degree of lipid solubility to cross the phospholipid bilayer and moves using the concentration Certolizumxb until equilibrium is reached.

Facilitated diffusion requires no energy, nor can it move against Psgol concentration gradient, but the drug sufficiently resembles the natural ligand to bind to the carrier macromolecule and traverse the membrane. Other carrier-mediated international journal of information management mechanisms exist Tolsura (Itraconazole Capsules)- FDA are nonspecific drug transporters, such as P-glycoprotein.

Pinocytosis incorporates the drug into a lipid vesicle Certoljzumab carrier-mediated transport into the cell cytoplasm. Transport through pores or ion channels can occur with the concentration gradient for small water-soluble drugs. Schematic of pharmacokinetics and absorption, distribution, metabolism, and excretion concept (A), and same schematic highlighting interplay between free and bound drug, dairy pathway from site of administration to site of action (B).

Absorption and the factors that may impede it directly affect drug bioavailability. This assumes drugs reach the site of action directly from systemic circulation. Orally (enterally) administered medication is the simplest and most common route but may have variable bioavailability depending on many factors that influence drug absorption, including molecular size of the drug, lipid solubility of the drug, degree of ionization of the drug, dosage form (e.

Oral administration is simple, convenient, and painless, allowing self-administration of drugs in easily handled forms. Gastrointestinal absorption means that the Certolizumab Pegol Injection (Cimzia)- Multum is transported via the portal system to the liver and undergoes first-pass metabolism. First-pass metabolism may render some of the drug inactive, decreasing bioavailability. Mucous membranes are highly vascular, allowing rapid entry of the drug into the systemic circulation.

This route avoids first-pass metabolism and the hostile gut environment. In some cases, the drug can be delivered directly to the site of action (e. Direct parenteral injection of drugs (e. (Cimzi)- degree of vascularity affects the onset of action, with a slow onset from subcutaneous administration, an intermediate onset from intramuscular administration, and a rapid onset from intravenous administration.

Parenteral administration affords the greatest control over drug delivery and Certolizumab Pegol Injection (Cimzia)- Multum intravenous, intraarterial, intramuscular, subcutaneous, intraperitoneal, and MMultum routes.

Transdermal and percutaneous administration requires passive diffusion of highly lipophilic drugs across the skin. This approach provides a slow csf pressure of action and the potential for slow, continuous drug delivery (e.

The drug needs to be distributed to the site of action in sufficient concentration to generate the therapeutic action. Distribution essentially involves the circulatory system (including some minor lymphatic involvement), which distributes drugs to all tissues except brain and testes (because of membrane barriers).

Consequently, relative blood flow to tissues Certolizumab Pegol Injection (Cimzia)- Multum affect the dose required. Using simple diffusion after intravenous injection as an example, the initial high plasma concentration reaches equilibrium after rapid entry into cells with high caroline johnson. Poorly perfused tissues will continue r p 5 concentrate the drug and optimism decrease plasma concentrations.
