Zero-order and first-order kinetics

FAQ

Those who are looking for an answer to the question «Zero order kinetics drugs?» often ask the following questions:

❓ When can drugs change from first to zero order kinetics?

A maximum rate of reaction is reached when drug concentration achieves 100% enzyme saturation. Beyond this concentration, clearance will be zero-order.

Question from categories: zero order kinetics drugs mnemonic drug delivery drug release

❓ Degradation kinetics of drugs?

Degradative reactions in pharmaceutical formulations take place at definite rates & are chemical in nature. Degradation kinetics aims to predict the intrinsic stability of a drug in order to anticipate problems that may arise during development 5

What Is Zero Order Kinetics? Zero order kinetics is a way of describing how the body uses and breaks down some medicines. While the rate at which the body eliminates most drugs is proportional to...

1.2.1 Zero order kinetics of drug release Zero order release kinetics refers to the ...

In contrast to methanol, other specific medications that show zero-order elimination are salicylates, omeprazole, fluoxetine, phenytoin, and cisplatin, which, when ingested at toxic levels, will achieve a higher concentration of the substance within the body over time versus the same amount of the substance that uses first-order elimination.

Zero order: a constant amount of drug is eliminated per unit time. For example 10mg of a drug maybe eliminated per hour, this rate of elimination is constant and is independent of the total drug concentration in the plasma. Zero order kinetics are rare Elimination mechanisms are saturable. Examples of zero order elimination include ethanol, phenytoin and salicylates (at high doses)

Ethanol follows zero order kinetics because the cofactor for ADH, NAD +, is quickly depleted. The elimination of ethanol depends only on how fast the liver can regenerate NAD + from NADH, which occurs at a constant rate; Phenytoin follows so-called non-linear pharmacokinetics, meaning that it follows zero order kinetics when given in high doses and first order kinetics when given in low doses

Zero order elimination kinetics: a constant amount (eg. so many milligrams) of drug is eliminated per unit time; First order kinetics is a concentration-dependent process (i.e. the higher the concentration, the faster the clearance), whereas zero order elimination rate is independent of concentration.

The best known example of zero order kinetics is alcohol. There are no notable examples of therapeutic drugs that have saturable metabolism and zero order kinetics. However, some therapeutic drugs...

A few substances are eliminated by zero-order elimination kinetics, because their elimination process is saturated. Examples are Ethanol, Phenytoin, Salicylates, Cisplatin, Fluoxetin, Omeprazol.

What does ‘zero tolerance’ on drugs mean?

A consistence of zero tolerance is the absolute dichotomy between the legality of any use and no use and the equating all illicit drugs and any form of use as undesirable and harmful to society. That contrasts the views of those who stress the disparity in harmfulness among drugs and would like to distinguish between occasional drug use and problem drug use.

A drug can have only linear or nonlinear kinetics?

Under these conditions, a constant amount of drug is eliminated per unit time no matter how much drug is in the body. Zero order kinetics then apply rather than the usual first order kinetics where a constant proportionof the drug in the body is eliminated per unit time. Some examples of drugs which exhibit non-linear kinetic behaviour are phenytoin, ethanol, salicylate and, in some individuals, theophylline.

Can orally administered drugs have a zero compartmental absorption?

Some drugs, notably insulin, are routinely administered SC. Drug 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.
